Objectives: Graft selection for skeletally mature adolescents undergoing anterior cruciate ligament (ACL) reconstruction is guided by surgeon and patient preference. In young patients returning to high-risk cutting and pivoting sports, graft rupture is the most feared complication of ACL reconstruction. Some studies have demonstrated slightly lower rates of graft failure and decreased laxity in the short term associated with patellar tendon (BTB) autografts as compared to hamstring (HS) autografts, but these studies are limited by their heterogeneity of ages and activity level. The purpose of this study is to compare the rates of graft failure between BTB and HS ACL reconstruction cohorts matched by age, sex, and sport. Methods: A single-institution retrospective review was performed of consecutive patients less than 19 years of age treated with ACL reconstructions using either patellar tendon (BTB) or hamstring (HS) autograft performed by a single surgeon. Skeletally mature or nearly mature patients in “high-risk” ACL injury sports (basketball, football, soccer, lacrosse, and gymnastics) were initially treated with hamstring autografts but the graft preference transitioned to BTB autografts as the preferred graft choice during the study period. This transition in graft preference for adolescents participating in “high risk” sports allows for a comparison of outcomes based on graft types. Inclusion criteria were ages 13 – 18 years, participation in a “high risk” sport, and minimum 24-month follow-up. The two cohorts of patients were matched by age, gender, and sport. The primary outcome measure was graft rupture. Results: One hundred twenty-six patients with an average age of 15.8 years (range 13 – 18 years) met inclusion criteria. There were 60 BTB reconstructions and 66 HS reconstructions. There were 55 females and 71 males. There was no difference in age, sex, BMI, or laterality between groups. There were more patients who played soccer in the BTB cohort (44%) vs HS cohort (22%) and fewer who played basketball in the BTB cohort (24%) vs HS cohort (38%), p = 0.005. There were no differences between the BTB and HS cohorts in terms of meniscus tears (60% v 68%, p = 0.34), meniscus repair (20% v 30%, p = 0.19), or partial meniscectomy (33% v 39%, p = 0.48). Mean duration of follow-up was 41 months (range 24-78 months). There was a difference in follow-up between cohorts (BTB 36 months and HS 50 months, p < 0.05). There were 16 graft ruptures (12.6%). There was no difference in the rate of graft rupture between cohorts (BTB 10.0% vs HS 15.2%, p = 0.45). Mean time to graft rupture was 21 months (range 8 – 35 months) and Kaplan-Meier survival curves demonstrated no difference between cohorts. The mean age of graft failures within the BTB cohort was 15.5 years as compared to 16.1 years for those that did not have a graft failure (p=0.268). The mean age of graft failures within the HS cohort was 14.9 years as compared to 15.9 years for those that did not have a graft failure (p<0.05). Conclusion: ACL reconstruction in adolescents returning to high-risk sports can be performed utilizing BTB or HS autografts with similar rates of graft rupture. Patients under the age of 15 years have a greater risk of failure associated with HS autograft as compared to patients 16 years of age and older with the same graft. In contrast, BTB grafts have similar failure rates regardless of age. There is a trend toward lower rates of graft rupture associated with BTB autografts, but additional patients will be necessary to determine if this trend will become a statistically significant difference.

Background: Graft selection for skeletally mature adolescents undergoing anterior cruciate ligament (ACL) reconstruction is guided by surgeon and patient preference. In young patients returning to high-risk cutting and pivoting sports, graft rupture is the most feared complication of ACL reconstruction. Some studies have demonstrated slightly lower rates of graft failure and decreased laxity in the short term associated with patellar tendon (BTB) autografts as compared to hamstring (HS) autografts, but these studies are limited by their heterogeneity of ages and activity level1-3. The purpose of this study is to compare the rates of graft failure between BTB and HS ACL reconstruction cohorts matched by age, sex, and sport. Methods: A single-institution retrospective review was performed of consecutive patients less than 19 years of age treated with ACL reconstructions using either patellar tendon (BTB) or hamstring (HS) autograft performed by a single surgeon. Skeletally mature or nearly mature patients in “high-risk” ACL injury sports (basketball, football, soccer, lacrosse, and gymnastics) were initially treated with hamstring autografts but the graft preference transitioned to BTB autografts as the preferred graft choice during the study period. This transition in graft preference for adolescents participating in “high risk” sports allows for a comparison of outcomes based on graft types. Inclusion criteria were ages 13 – 18 years, participation in a “high risk” sport, and minimum 6-month follow-up. The two cohorts of patients were matched by age, gender, and sport. The primary outcome measure was graft rupture. Results: One hundred fifty-two patients with an average age of 16 years (range 13 – 18 years) underwent ACL reconstruction during the study period. There were 71 BTB reconstructions and 81 HS reconstructions. There were 64 females and 88 males. There was no difference in age, sex, BMI, or laterality between groups. There were more patients who played soccer in the BTB cohort (44%) vs HS cohort (20%) and fewer who played basketball in the BTB cohort (24%) vs HS cohort (41%), p = 0.005. There were no differences between the BTB and HS cohorts in terms of meniscus tears (61% v 72%, p = 0.15), meniscus repair (21% v 32%, p = 0.13), or partial meniscectomy (32% v 33%, p = 0.90). Mean duration of follow-up was 28 months (range 7-57 months). There was no difference in follow-up between cohorts (BTB 28 months and HS 29 months, p = 0.19). There were a total of 16 graft ruptures (10.5%). There was no difference in the rate of graft rupture between cohorts (BTB 8.5% vs HS 12.3%, p = 0.60). Mean time to graft rupture was 21 months (range 8 – 35 months) and Kaplan-Meier survival curves demonstrated no difference between cohorts. Conclusions: ACL reconstruction in adolescents returning to high-risk sports can be performed utilizing BTB or HS autografts with similar rates of graft rupture. There is a trend toward lower rates of graft rupture associated with BTB autografts, but additional patients will be necessary to determine if this trend will become a statistically significant difference.

Objectives: ACL reconstruction in adolescents is commonly performed with hamstring autografts. In the adolescent population with very high activity levels, graft rupture is the most feared complication of ACL reconstruction. Young age, higher activity level, allografts, and small graft diameter have been shown to be predictors of graft failure. The applicability of this data to pediatric ACL reconstructions is limited due to heterogeneity of ages, graft constructs, and tunnel techniques. The purpose of this study is to evaluate the association of soft tissue graft constructs and graft rupture following pediatric transphyseal ACL reconstruction. Our hypothesis is that allograft-augmentation of grafts is associated with an increased risk of graft rupture. Methods: A single-institution retrospective review was performed of consecutive patients. Inclusion criteria were age less than 20 years and transphyseal ACL reconstruction with hamstring autograft, with or without allograft augmentation. Graft constructs included 4-strand doubled semitendinosus and gracilis (4-STG), 5-strand tripled semitendinosus and doubled gracilis (5-STG), 6-strand doubled gracilis and semitendinosus plus allograft (6-STGAllo), and 7-strand tripled semitendinosus and doubled gracilis plus allograft (7-STGAllo). Exclusion criteria included multiligament reconstruction and less than 6 months follow-up. The primary outcome was graft rupture. Results: Three hundred fifty-five patients (157 males, 198 females) with an average age of 15.3 years were identified to meet inclusion criteria. Graft constructs included 4-STG (198), 5-STG (91), 6-STGAllo (65), and 7-STGAllo (1). Average graft diameter was 8.3 mm 4-STG, 8.9 mm 5-STG, and 9.2 mm 6-STGAllo. Age and graft sizes were significantly different across groups with older patients (p <0.001) and larger graft sizes (p <0.001) being found in patients with allograft-augmented grafts. Mean duration of follow-up was 26 months (range 6-56 months). There were 51 graft ruptures (14.3%). The failure rate of each construct was 13.6% 4-STG, 11.9% 5-STG, and 19.7% 6-STGAllo. Time to graft failure was 16 months (range 2-40 months), with 49% of failures occurring before 12 months and 24% after 24 months. Twenty-four patients (6.7%) had a contralateral ACL tear during the follow-up period. Table 1 provides population characteristics by graft rupture status. This data suggests that patients who sustain a graft rupture may be slightly younger (p=0.07) and have lower BMI (p=0.07) than those patients without graft rupture. Odds ratios for graft failure by graft construct, controlling for age and graft size were calculated. Patients with 6-STGAllo grafts had an odds ratio of 2.6 (95% CI: 1.02, 6.50) of graft rupture as compared to 4-STG. Conclusion: ACL reconstruction with hamstring autograft combined with soft tissue allograft have a 2.6 times risk of graft rupture as compared to hamstring autograft without augmentation. In situations where the surgeon harvests an inadequately sized 4-strand autograft, we recommend tripling the semitendinosus to produce a larger graft diameter rather than augment with an allograft.

Background: Graft failure and low rates of return to sport are major concerns after anterior cruciate ligament (ACL) reconstruction, particularly in a population at risk. Purpose: To evaluate the association between reconstruction techniques and subsequent graft rupture and return-to-sport rates in patients aged 16 to 30 years participating in pivoting sports. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective study of patients undergoing primary ACL reconstruction with a bone–patellar tendon–bone (B-PT-B) graft, quadrupled hamstring tendon (4HT) graft, or hamstring tendon graft combined with anterolateral ligament reconstruction (HT+ALL) was conducted by the Scientific ACL NeTwork International (SANTI) Study Group. Survivorship data from Kaplan-Meier analysis were analyzed in multivariate Cox regression models to identify the prognosticators of graft ruptures and return to sport. Results: Five hundred two patients (mean age, 22.4 ± 4.0 years) with a mean follow-up of 38.4 ± 8.5 months (range, 24-54 months) were included. There were 105 B-PT-B, 176 4HT, and 221 HT+ALL grafts. The mean postoperative scores at latest follow-up were the following: Lysholm: 92.4 ± 8.6, Tegner: 7.4 ± 2.1, and subjective International Knee Documentation Committee (IKDC): 86.8 ± 10.5 for B-PT-B grafts; Lysholm: 91.3 ± 9.9, Tegner: 6.6 ± 1.8, and subjective IKDC: 85.4 ± 10.4 for 4HT grafts; and Lysholm: 91.9 ± 10.2, Tegner: 7.0 ± 2.0, and subjective IKDC: 81.8 ± 13.1 for HT+ALL grafts. The mean side-to-side laxity was 0.6 ± 0.9 mm for B-PT-B grafts, 0.6 ± 1.0 mm for 4HT grafts, and 0.5 ± 0.8 mm for HT+ALL grafts. At a mean follow-up of 38.4 months, the graft rupture rates were 10.77% (range, 6.60%-17.32%) for 4HT grafts, 16.77% (range, 9.99%-27.40%) for B-PT-B grafts, and 4.13% (range, 2.17%-7.80%) for HT+ALL grafts. The rate of graft failure with HT+ALL grafts was 2.5 times less than with B-PT-B grafts (hazard ratio [HR], 0.393; 95% CI, 0.153-0.953) and 3.1 times less than with 4HT grafts (HR, 0.327; 95% CI, 0.130-0.758). There was no significant difference in the graft failure rate between 4HT and B-PT-B grafts (HR, 1.204; 95% CI, 0.555-2.663). Other prognosticators of graft failure included age ≤25 years ( P = .012) and a preoperative side-to-side laxity >7 mm ( P = .018). The HT+ALL graft was associated with higher odds of returning to preinjury levels of sport than the 4HT graft (odds ratio [OR], 1.938; 95% CI, 1.174-3.224) but not compared with the B-PT-B graft (OR, 1.460; 95% CI, 0.813-2.613). Conclusion: In a high-risk population of young patients participating in pivoting sports, the rate of graft failure with HT+ALL grafts was 2.5 times less than with B-PT-B grafts and 3.1 times less than with 4HT grafts. The HT+ALL graft is also associated with greater odds of returning to preinjury levels of sport when compared with the 4HT graft.

Objectives: Most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome. The purpose of this study was to determine if revision ACL graft choice predicts outcomes related to sports function, activity level, OA symptoms, graft re-rupture, and reoperation at six years following revision reconstruction. We hypothesized that autograft use would result in increased sports function, increased activity level, and decreased OA symptoms (as measured by validated patient reported outcome instruments). Additionally, we hypothesized that autograft use would result in decreased graft failure and reoperation rate 6 years following revision ACL reconstruction. Methods: Revision ACL reconstruction patients were identified and prospectively enrolled by 83 surgeons over 52 sites. Data collected included baseline demographics, surgical technique and pathology, and a series of validated patient reported outcome instruments (IKDC, KOOS, WOMAC, and Marx activity rating score). Patients were followed up for 6 years, and asked to complete the identical set of outcome instruments. Incidence of additional surgery and re-operation due to graft failure were also recorded. Multivariate regression models were used to determine the predictors (risk factors) of IKDC, KOOS, WOMAC, Marx scores, graft re-rupture, and re-operation rate at 6 years following revision surgery. Results: 1234 patients were successfully enrolled with 716 (58%) males. Median age was 26. In 87% this was their first revision. 367 (30%) were undergoing revision by the surgeon that had performed the previous reconstruction. 598 (48%) underwent revision reconstruction utilizing an autograft, 599 (49%) allograft, and 37 (3%) both autograft and allograft. Median time since their last ACL reconstruction was 3.4 years. Questionnaire follow-up was obtained on 810 subjects (65%), while phone follow-up was obtained on 949 subjects (76%). The IKDC, KOOS, and WOMAC scores (with the exception of the WOMAC stiffness subscale) all significantly improved at the 6-year follow-up time point (p<0.001). Contrary to the IKDC, KOOS, and WOMAC scores, the 6-year MARX activity scale demonstrated a significant decrease from the initial score at enrollment (p<0.001). Graft choice proved to be a significant predictor of 6-year Marx activity level scores (p=0.005). Specifically, the use of an autograft for revision reconstruction predicted improved activity levels [Odds Ratio (OR) = 1.54; 95% confidence intervals (CI) = 1.14, 2.04]. Graft choice proved to be a significant predictor of 6-year IKDC scores (p=0.018), in that soft tissue grafts predicted higher 6-year IKDC scores [OR = 1.62; 95% confidence intervals (CI) = 1.09, 2.414]. For the KOOS subscales, graft choice did not predict outcome score. Graft re-rupture was reported in 55/949 (5.8%) of patients by their 6-year follow-up: 37 allografts, 16 autografts, and 2 allograft + autograft. Use of an autograft for revision resulted in patients 6.04 times less likely to sustain a subsequent graft rupture than if an allograft was utilized (p=0.009; 95% CI=1.57, 23.2). Conclusion: Improved sports function and patient reported outcome measures are obtained when an autograft is utilized. Additionally, autograft type shows a decreased risk in graft re-rupture at six years follow-up. Surgeon education regarding the findings in this study can result in potentially improved revision ACLR results for our patients.

Background: Clinical studies have demonstrated significant advantages of combined anterior cruciate ligament and anterolateral ligament reconstruction (ACL+ALLR) over isolated ACL reconstruction (ACLR) with respect to reduced graft rupture rates, a lower risk of reoperation for secondary meniscectomy, improved knee stability, and higher rates of return to sports. However, no long-term studies exist. Purpose/Hypothesis: The purpose of this study was to compare the outcomes of isolated ACLR versus ACL+ALLR at long-term follow-up. The hypothesis was that patients who underwent combined procedures would experience significantly lower rates of graft rupture. Study Design: Cohort study; Level of evidence, 3. Methods: Patients undergoing primary ACL+ALLR between January 2011 and March 2012 were propensity matched in a 1:1 ratio to patients who underwent isolated ACLR during the same period. A combination of face-to-face and telemedicine postoperative follow-up was undertaken. At the end of the study period (March 2020), medical notes and a final telemedicine interview were used to determine whether patients had experienced any complications or reoperations. The Knee injury and Osteoarthritis Outcome Score, International Knee Documentation Committee score, Lysholm score, and Tegner score were collected for all patients. Graft survivorship was assessed using Kaplan-Meier analysis. Logistic regression was performed to account for the potential effect of activity level on graft rupture rates. Results: A total of 86 matched pairs were included in the study. The mean ± SD age was 32.2 ± 8.8 years (range, 22-67 years) in the ACL+ALLR group and 34.7 ± 8.5 years (range, 21-61 years) in the isolated ACLR group. The mean duration of follow-up was 104.33 ± 3.74 months (range, 97-111 months). Patients who underwent combined ACL+ALLR versus isolated ACLR experienced significantly better ACL graft survivorship (96.5% vs 82.6%, respectively; P = .0027), lower overall rates of reoperation (15.3% vs 32.6%; P < .05), and lower rates of revision ACLR (3.5% vs 17.4%; P < .05). Patients undergoing isolated ACLR were at >5-fold greater risk of graft rupture (odds ratio, 5.549; 95% CI, 1.431-21.511; P = .0132), regardless of their preinjury activity level. There were no significant differences between groups with respect to other complications or any clinically important differences in patient-reported outcome measures. Conclusion: Patients who underwent combined ACL+ALLR experienced significantly better long-term ACL graft survivorship, lower overall rates of reoperation, and no increase in complications compared with patients who underwent isolated ACLR. Further, patients who underwent isolated ACLR had a >5-fold increased risk of undergoing revision surgery at a mean follow-up of 104.3 months.

Objective This prospective randomized study was performed to compare the outcomes of two operative methods of anterior cruciate ligament (ACL) reconstruction based on either bone–patellar tendon–bone (BTB) grafts or hamstring tendon (HT) grafts. Methods Among 100 patients, 96 completed the full follow-up period and were included in the final analysis (48 in the BTB group and 48 in the HT group). The patients were evaluated preoperatively and 1, 3, 6, and 12 months after ACL reconstruction. The Kujala score, Tegner score, and Knee injury and Osteoarthritis Outcome Score (KOOS) were among the parameters used to evaluate the patients. Results Both groups were comparable in terms of sex, age, and body mass index. None of the analyzed scores were significantly different between the BTB and HT groups at either the initial or last visit. Both groups demonstrated improvement at the 12-year follow-up according to the Kujala score and most categories of the KOOS. The Tegner activity level score showed significant improvement in the HT but not BTB group. Conclusion Patients undergoing ACL reconstruction with BTB and HT grafts show comparable improvement in functional results after 1 year of rehabilitation.

Background Several studies have examined ACL injury history among relatives of patients undergoing ACL reconstruction, but they have primarily analyzed adult populations with variable results. Additionally, few studies have examined concomitant injuries or post-operative outcomes among pediatric patients with a family history of ACL tear. Therefore, the purpose of this study was to identify the proportion of pediatric ACL patients with a first degree relative who had suffered an ACL tear while also examining concomitant meniscal or ligamentous injuries and subsequent complication rates. Methods 1009 patients who underwent ACL reconstruction at an urban tertiary care children’s hospital between January 2009 and May 2016 were contacted via email and/or telephone and asked to complete a follow-up survey. Data collected included subsequent complications – including graft rupture, contralateral ACL injury, and meniscus tears – along with information regarding any relatives who had suffered an ACL tear. Patient medical records were reviewed to determine the age of the patient at the time of surgery as well as concomitant meniscus and ligamentous injuries at the time of injury. Results 425 patients who underwent primary ACL reconstruction completed the survey. The mean age at surgery was 15.0? 2.4 years with a mean follow-up time of 4.6? 2.1 years. Patients were stratified into three groups by the number of first degree relatives (parent or sibling) who had an ACL tear history: no relatives, one relative, or more than one relative. 101 respondents (23.8%) reported at least one first degree relative who had previously torn an ACL. 15 (3.5%) had more than one first degree relative with an ACL tear. There were no differences in the age at time of surgery or the number of concomitant meniscus and ligamentous injuries suffered across the three stratified groups. While children with zero or one affected first degree relative had similar rates of graft failure (11.4% and 9.3%, respectively), those with two or more affected first-degree relatives had a significantly higher graft failure rate (40.0%, p=0.003). There were no differences in the number of post-operative contralateral ACL tears (p=0.438) or meniscus tears (p=0.477) across the groups. When these complications were analyzed together as one outcome, patients with more than one affected first-degree relative suffered more combined graft ruptures, contralateral ACL tears, and meniscal tears (53.3%) than patients with zero (21.9%) or only one affected first degree relative (22.1%, p=0.02). This group of patients also suffered more total complications that required surgical intervention (66.7%) than patients with zero (21.0%) or only one affected first degree family member (22.1%, p<0.001). Conclusion/Significance Patients undergoing primary ACL reconstruction who have a strong family history of ACL tear appear more likely to suffer a post-operative graft rupture and suffer a complication requiring surgery.

AbstractThe current review aims to compare the outcomes of anterior cruciate ligament (ACL) reconstruction in the female population after patellar–tendon–bone and hamstring grafts. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All original randomized controlled trials and prospective cohort studies that compared clinical outcomes after female ACL reconstruction using hamstring versus patellar–tendon–bone grafts were included. All clinical outcomes reported by three or more studies were included. Fifteen publications, with 948 female patients, were included. Most outcomes were reported to have no significant graft differences by all studies that reported the outcome. These included all the outcomes for objective knee scores (International Knee Documentation Committee [IKDC] objective knee score), neuromuscular testing (quadriceps strength, hamstring strength, and single hop test), graft rupture or failure, and subjective knee scores (Lysholm score and IKDC subjective knee score). The pivot shift test, flexion deficit, and presence of crepitus were also reported to have no significant graft differences by all studies. Some studies reported a significant difference in anteroposterior laxity (Lachman's test and instrumented laxity), range of motion deficits (extension deficit), and sports and activity level (Tegner score). However, these statistically significant differences were noted to be clinically insignificant due to the normal population variation or standard error of measurement of these tools of evaluation. Patients reconstructed with patellar-tendon–bone grafts have a higher risk of kneeling pain. There was no significant difference in the incidence of crepitus. Most of the outcomes following female ACL reconstructions showed no clinically and statistically significant difference when either patellar–tendon–bone or hamstring autograft was used. These included outcomes for anteroposterior laxity, objective knee scores, neuromuscular testing, graft rupture or failure, subjective knee scores, sports and activity level, and crepitus. This a level II study.

Background: The increased prevalence of anterior cruciate ligament (ACL) reconstruction has led to an increased need for revision ACL reconstructions. Despite the growing body of literature indicating that single-stage revision ACL reconstruction can yield good outcomes, there is a lack of data for determining when and how to safely perform a single-stage revision. Purpose: To assess the outcomes, graft failure rates, and return-to-play rates of a decision-making algorithm for single-stage revision ACL reconstruction. Study Design: Case series; Level of evidence, 4. Methods: We reviewed a consecutive series of revision ACL reconstructions performed by the senior author between September 2009 and July 2016 with minimum 2-year follow-up. All patients were assessed, and decision making was undertaken according to the algorithm. Outcomes measured were further surgery, graft rerupture, re-revision, Tegner score, and Knee injury and Osteoarthritis Outcome Score (KOOS). For the elite athlete population, return-to-play time, duration, and level of play after surgery as compared with preinjury were also determined. Results: During this period, 93 procedures were performed in 92 patients (40 elite athletes). Two 2-stage procedures were undertaken, leaving 91 single-stage procedures (91 patients) to form the basis for further study. At a mean 4.3 years (SD, 2.2 years) after surgery, there had been 2 re-revisions (2.2%) and 2 further instances of graft failure that had not been re-revised (total graft failure rate, 4.4%). There were 17 subsequent procedures, including 6 arthroscopic partial meniscectomies, 5 removals of prominent implants, and 1 total knee arthroplasty. The mean Tegner score was 8.02 before graft rerupture and 7.1 at follow-up. At follow-up, the mean KOOS outcomes were 79.3 for Symptoms, 88.0 for Pain, 94.2 for Activities of Daily Living, 73.6 for Sport, and 68.9 for Quality of Life. Of 40 elite athletes, 35 returned to play at a mean 11.2 months (SD, 3.6 months) after surgery. Conclusion: Single-stage revision ACL reconstructions can be performed reliably in the majority of patients, with good clinical outcomes, low rerupture rates, and high-return-to play rates, even in the elite athlete population.

Background: Revision anterior cruciate ligament (ACL) reconstruction can be potentially devastating for a patient. As such, it is important to identify prognostic factors that place patients at an increased risk for graft failure. There are no data on the effects of patellar tendinopathy on failure of ACL reconstruction when using a bone–patellar tendon–bone (BPTB) autograft. Purpose/Hypothesis: The purpose of this study was to investigate the association of patellar tendinopathy with the risk of graft failure in primary ACL reconstruction when using a BPTB autograft. The hypothesis was that patellar tendinopathy would result in higher rates of graft failure when using a BPTB autograft for primary ACL reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: All patients undergoing ACL reconstruction at a single institution from 2005 to 2015 were examined. A total of 168 patients undergoing primary ACL reconstruction with a BPTB autograft were identified. Patients’ magnetic resonance imaging scans were reviewed for the presence and grade of patellar tendinopathy by 2 musculoskeletal fellowship–trained radiologists; both were blinded to the aim of the study, patient demographics, surgical details, and outcomes. Patients were divided into 2 groups: failure (defined as presence of symptomatic laxity or graft insufficiency) and success of the ACL graft. Statistical analyses were run to examine the association of patellar tendinopathy with failure of ACL reconstruction using a BPTB autograft. Results: At a mean follow-up of 18 months, there were 7 (4.2%) patients with graft failure. Moderate or severe patellar tendinopathy was associated with ACL graft failure ( P = .011). Age, sex, and side of reconstruction were not associated with the risk of graft failure, although the majority of patients who failed were younger than 20 years. The use of patellar tendons with moderate to severe tendinopathy was associated with a relative risk of ruptures of 6.1 (95% CI, 1.37-27.34) as compared with autograft tendons without tendinopathy. Conclusion: Moderate or severe patellar tendinopathy significantly increases the risk of graft failure when using a BPTB autograft for primary ACL reconstruction. Patellar tendinopathy should be considered when determining the optimal graft choice for patients undergoing primary ACL reconstruction with autograft tendons.
