Objectives: The increased prevalence of anterior cruciate ligament (ACL) reconstructions has led to an increased need for revision ACL reconstructions. Despite the lack of comparative literature, two-stage revisions are often undertaken under the pretense they are safer. Through careful patient selection, pre-operative planning, and meticulous attention to detail, single stage revisions can be performed with good outcomes, decreasing healthcare costs, morbidity and recovery time for the patient. The objective of this paper is to present an algorithm (Figure 1) to determine single-stage or two-stage approaches to ACL revision with good outcomes in recreational and elite athletes. Methods: All revision ACL reconstructions performed by the senior author from September 2009 to July 2016, with minimum two year follow-up, were retrospectively reviewed. Outcomes measured were: any further surgery, graft re-rupture, re-revision, Tegner score, and knee injury and osteoarthritis outcomes score (KOOS). For the elite athlete population, return to play time, duration and level compared to pre-injury were also determined. Results: Ninety-four procedures were performed in 93 patients. This included 41 in elite athletes. In this series only 2 (2%) two-stage procedures were undertaken. At an average of 4.3 years (range: 2-8.5 years) post surgery, there had been two re-revisions. There were two further instances of graft failure which had not been re-revised. The graft failure rate was therefore 4.3%. There were 17 subsequent procedures, including six arthroscopic partial meniscectomies, five removal of prominent implants, and one total knee arthroplasty. The average Tegner score was 8.2 preoperatively, and 7.1 at follow up. At follow up, the average KOOS scores 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. Thirty-six of 41 elite athletes returned to play, at an average of 338 days post surgery. At an average of 4.6 years, 29 were still playing professionally. Of these, 15 were at the same level, and 14 at a lower level. Five players returned to play but have since retired. This occurred at an average of 3.1 years post op, at an age of 30. Conclusion: Single stage ACL revisions can be performed reliably in the majority, but not all, patients with persistent or recurrent instability following failed ACL reconstruction with good clinical outcomes and return to play, even in the elite athletic population.

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.

ImportanceDespite advances in surgical techniques and postoperative rehabilitation, long-term anterior cruciate ligament (ACL) graft rupture rate remains high. The increasing number of primary ACL reconstructions in an ageing population will lead to increasing revision reconstructions. Revision cases may have higher failure rates and worse patient-reported outcomes compared with primaries. While two-stage revisions may be indicated in certain complex cases, whether this is comparatively equivalent or even superior to revisions done in a single stage would assist preoperative planning.ObjectiveThe objective of this systematic review was to analyse and compare patient-reported outcomes and failure rate of single-stage versus two-stage revision ACL reconstruction.Evidence reviewUsing PubMed, MEDLINE Complete and Ovid MEDLINE databases, a review was performed using Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines to identify level I–IV outcomes of revision ACL reconstruction with a minimum follow-up of 24 months.FindingsThree studies reported outcomes of two-stage revisions with mean follow-up of 61.6 months, while 21 studies reported single-stage revisions with mean follow-up of 47.4 months. Pooled rate of two-stage revisions was 3.1% compared with 6.8% in single-stage (p=0.068). Clinical failure was reported in 5.1% of 79 two-stage patients compared with 13.8% of 533 single-stage patients (p<0.05). Within the single-stage cohort, there was a greater clinical failure rate (+8.7%, p<0.05) for patients with less than 48 months follow-up. Those with > 48 months follow-up had a higher rerupture rate (+5%, p<0.05) and a significantly greater sum of squared deviations (p<0.05) compared with those with < 48 months follow-up. Patient-reported outcomes have demonstrated two-stage revision patients with higher IKDC A and B scores than single-stage.Conclusions and relevanceAlthough two-stage revisions may be performed in more complex cases, there are limited short-term data available regarding their outcomes. Two-stage revisions demonstrated comparable clinical outcomes and lower rate of revision surgery and clinical failure compared with single-stage revisions. Studies with shorter follow-up (24–48 months) showed higher clinical failure rates. Those with longer follow-up (>48 months) showed higher graft rerupture rates. The decision to perform staged reconstruction should made on whether adequate tunnel placement and fixation can be established in a single setting.Level of evidenceLevel IV.

Background: There is increased interest in understanding the preoperative determinants of postoperative outcomes. Return to play (RTP) and the patient-reported minimal clinically important difference (MCID) are useful measures of postoperative outcomes after anterior cruciate ligament reconstruction (ACLR). Purpose: To define the MCID after ACLR and to investigate the role of preoperative outcome scores for predicting the MCID and RTP after ACLR. Study Design: Case-control study; Level of evidence, 3. Methods: There were 294 active athletes enrolled as part of an institutional ACL registry with a minimum 2-year follow-up who were eligible for inclusion. A questionnaire was administered to elicit factors associated with RTP. Patient demographic and clinical data as well as patient-reported outcome measures were captured as part of the registry. Outcome measures included the International Knee Documentation Committee (IKDC) subjective knee evaluation form, Lysholm scale, and 12-Item Short Form Health Survey (SF-12) physical component summary (PCS) and mental component summary (MCS). Preoperative outcome score thresholds predictive of RTP were determined using a receiver operating characteristic (ROC) with area under the curve (AUC) analysis. The MCID was calculated using a distribution-based method. Multivariable logistic models were fitted to identify predictors for achieving the MCID and RTP. Results: At a mean (±SD) follow-up of 3.7 ± 0.7 years, 231 patients were included from a total 294 eligible patients. The mean age and body mass index were 26.7 ± 12.5 years and 23.7 ± 3.2 kg/m2, respectively. Of the 231 patients, 201 (87.0%) returned to play at a mean time of 10.1 months. Two-year postoperative scores on all measures were significantly increased from preoperative scores (IKDC: 50.1 ± 15.6 to 87.4 ± 10.7; Lysholm: 61.2 ± 18.1 to 89.5 ± 10.4; SF-12 PCS: 41.5 ± 9.0 to 54.7 ± 4.6; SF-12 MCS: 53.6 ± 8.1 to 55.7 ± 5.7; P < .001 for all). The corresponding MCID values were 9.0 (IKDC), 10.0 (Lysholm), 5.1 (SF-12 PCS), and 4.3 (SF-12 MCS). Preoperative score thresholds predictive of RTP were the following: IKDC, 60.9; Lysholm, 57.0; SF-12 PCS, 42.3; and SF-12 MCS, 48.3. These thresholds were not independently predictive but achieved significance as part of the multivariable analysis. In the multivariable analysis for RTP, preoperative SF-12 PCS scores above 42.3 (odds ratio [OR], 2.73; 95% CI, 1.09-7.62) and SF-12 MCS scores above 48.3 (OR, 4.41; 95% CI, 1.80-10.98) were predictive for achieving RTP; an ACL allograft (OR, 0.26; 95% CI, 0.06-1.00) was negatively predictive of RTP. In the multivariable analysis for the MCID, patients with higher preoperative scores were less likely to achieve the MCID ( P < .0001); however, a higher preoperative SF-12 MCS score was predictive of achieving the MCID on the IKDC form (OR, 1.27; 95% CI, 1.11-1.52) and Lysholm scale (OR, 1.08; 95% CI, 1.00-1.16). Medial meniscal injuries, older age, and white race were also associated with a decreased likelihood for achieving the MCID. Conclusion: Preoperative SF-12 MCS and PCS scores were predictive of RTP after ACLR; patients scoring above 42.3 on the SF-12 PCS and 48.3 on the SF-12 MCS were more likely to achieve RTP. Additionally, we defined the MCID after ACLR and found that higher SF-12 MCS scores were predictive of achieving the MCID on knee-specific questionnaires.

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.

Background: The occurrence of physiologic knee hyperextension (HE) in the revision anterior cruciate ligament reconstruction (ACLR) population and its effect on outcomes have yet to be reported. Hypothesis/Purpose: The prevalence of knee HE in revision ACLR and its effect on 2-year outcome were studied with the hypothesis that preoperative physiologic knee HE ≥5° is a risk factor for anterior cruciate ligament (ACL) graft rupture. Study Design: Cohort study; Level of evidence, 2. Methods: Patients undergoing revision ACLR were identified and prospectively enrolled between 2006 and 2011. Study inclusion criteria were patients undergoing single-bundle graft reconstructions. Patients were followed up at 2 years and asked to complete an identical set of outcome instruments (International Knee Documentation Committee, Knee injury and Osteoarthritis Outcome Score, WOMAC, and Marx Activity Rating Scale) as well as provide information regarding revision ACL graft failure. A regression model with graft failure as the dependent variable included age, sex, graft type at the time of the revision ACL surgery, and physiologic preoperative passive HE ≥5° (yes/no) to assess these as potential risk factors for clinical outcomes 2 years after revision ACLR. Results: Analyses included 1145 patients, for whom 2-year follow-up was attained for 91%. The median age was 26 years, with age being a continuous variable. Those below the median were grouped as “younger” and those above as “older” (age: interquartile range = 20, 35 years), and 42% of patients were female. There were 50% autografts, 48% allografts, and 2% that had a combination of autograft plus allograft. Passive knee HE ≥5° was present in 374 (33%) patients in the revision cohort, with 52% being female. Graft rupture at 2-year follow-up occurred in 34 cases in the entire cohort, of which 12 were in the HE ≥5° group (3.2% failure rate) and 22 in the non-HE group (2.9% failure rate). The median age of patients who failed was 19 years, as opposed to 26 years for those with intact grafts. Three variables in the regression model were significant predictors of graft failure: younger age (odds ratio [OR] = 3.6; 95% CI, 1.6-7.9; P = .002), use of allograft (OR = 3.3; 95% CI, 1.5-7.4; P = .003), and HE ≥5° (OR = 2.12; 95% CI, 1.1-4.7; P = .03). Conclusion: This study revealed that preoperative physiologic passive knee HE ≥5° is present in one-third of patients who undergo revision ACLR. HE ≥5° was an independent significant predictor of graft failure after revision ACLR with a >2-fold OR of subsequent graft rupture in revision ACL surgery.

Background: The incidence of anterior cruciate ligament (ACL) injury in the adolescent population is increasing. The quadriceps tendon–patellar bone autograft (QPA) has been established as a reliable graft choice for ACL reconstruction in the adult population. Purpose: To investigate graft failure, ability to return to sport, patient-reported functional outcomes, joint laxity, and subsequent injury among adolescent patients >2 years after primary ACL reconstruction with the QPA. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients who underwent QPA ACL reconstruction performed by a single surgeon were identified from an existing database. Information available in the database included demographics, concomitant/subsequent injuries, surgical procedures, graft failure, return to sport, and Lachman examination collected by medical record review. Pediatric International Knee Documentation Committee (Pedi-IKDC) and Lysholm scores were collected by telephone or during a clinic visit >2 years postoperatively. Results: The final cohort included 81 of 104 consecutive adolescent patients aged 10 to 18 years (mean ± SD, 15.9 ± 1.7 years at the time of surgery) for whom follow-up information was collected at >2 years after surgery. The cumulative incidence of graft failure within the 36-month follow-up period was 1.2% (95% CI, 0.1%-11.4%). The rate of ipsilateral non-ACL injuries was similar (1.2%; 95% CI, 0.2%-7.6%). Contralateral ACL and non-ACL injuries requiring surgical intervention were documented in 9.8% (95% CI, 4.9%-19.5%). The median Pedi-IKDC score was 94 (interquartile range, 89-98). The median Lysholm score was 99.5 (interquartile range, 89.0-100.0). At 36 months after surgery, 87.9% (95% CI, 81.4%-94.9%) of individuals had returned to play. Conclusion: The quadriceps tendon–patellar autograft is a novel graft that demonstrates excellent stability and favorable patient-reported outcomes. Based on these results, the QPA is a reliable choice for primary ACL reconstruction in adolescent patients.

Objectives: The incidence of ACL injuries in WNBA athletes has been on the rise, despite the high rates of ACL injury there is a paucity of recent research examining the effect of ACL reconstruction on RTP and performance in these athletes. This cohort study seeks to quantify the effect of ACL reconstruction on RTP and performance on WNBA athletes. Methods: All ACL tears sustained in the WNBA from 1997-2018 were identified. BMI, age and position at the time of injury were collected for each player. RTP rates were calculated and performance data was collected for each player before and after injury to determine changes in playing time and statistical performance. Players who successfully RTP after ACL reconstruction were compared to a group of healthy controls who were matched by age, years of experience, position, height, and BMI. Statistics at one year and three years’ post-injury were compared to assess acute and longitudinal changes in performance relative to pre-injury baseline. Results: A total of fifty-nine WNBA players sustained an isolated ACL tear during the study period. Forty-one (69.5%) were able to RTP. There was no difference in demographic characteristics between forty-one players and matched controls. Following RTP athletes played an average of 7.5±12.8 fewer games, 5.1±9.2 fewer minutes per game, and scored 3.7±5.0 less points per game in their first year compared to the year prior to injury. (Table1) When compared to matched controls, WNBA players returning from ACL reconstruction demonstrated a significant decline in games played, games started, minutes per game, rebounds, assists, and blocks per game in their first season after RTP. These differences resolved by year three post-surgery (Table 2). Conclusions: There is a high RTP rate following ACL reconstruction in WNBA athletes. Players may experience a decrease in playing time and performance initially when returning to play, however these variables were found to return to baseline over time.

Background: Despite the importance of return-to-play (RTP) rates, second anterior cruciate ligament (ACL) injury rates, and patient-reported outcomes of athletes returning to sports after ACL reconstruction (ACLR), these outcomes have not been evaluated together across a single cohort nor the pre- and intraoperative factors influencing outcomes explored. Purpose: To prospectively report outcomes after ACLR relating to RTP, second ACL injury, and International Knee Document Committee (IKDC) scores in a large cohort of athletes at a single center to examine the influence of pre- and intraoperative variables on these outcomes. Design: Cohort study; Level of evidence, 3. Methods: A consecutive cohort of 1432 athletes undergoing primary ACLR by 2 orthopaedic surgeons was followed up prospectively more than 2 years after surgery. Pre- and intraoperative findings were reported with outcomes at follow-up relating to RTP, second ACL injury, and IKDC. Between-group differences for each outcome were reported and the predictive ability of pre- and intraoperative variables relating to each outcome assessed with logistic regression. Results: There was >95% follow-up 2 years after surgery. The RTP rate was 81%, and of those who returned, 1.3% of those with patellar tendon grafts and 8.3% of those with hamstring grafts experienced ipsilateral rerupture (hazard ratio, 0.17). The contralateral ACL injury rate was 6.6%, and the IKDC score at follow-up was 86.8, with a greater proportion of patients with patellar tendon grafts scoring <80 on the IKDC (odds ratio, 1.56; 95% CI, 1.15-3.12). There was no relationship between time to RTP and second ACL injury, and there was a moderate correlation between ACL–Return to Sport After Injury score and RTP at follow-up ( P < .001, rho = 0.46). There were a number of differences in pre- and intraoperative variables between groups for each outcome, but they demonstrated a poor ability to predict outcomes in level 1 athletes at 2-year follow-up. Conclusion: Findings demonstrated high overall RTP rates, lower reinjury rates with patellar tendon graft after 2-year follow-up in level 1 athletes, and no influence of time to RTP on second ACL injury. Despite differences between groups, there was poor predictive ability of pre- and intraoperative variables. Results suggest pre- and intraoperative variables for consideration to optimize outcomes in level 1 athletes after ACLR, but future research exploring other factors, such as physical and psychological recovery, may be needed to improve outcome prediction after ACLR.

Background: Treatment of anterior cruciate ligament (ACL) injuries in the adolescent population continues to be complicated by an unacceptably high rate of secondary ACL injury. Purpose: To describe the failure rate and outcomes after a hybrid pediatric ACL reconstruction (ACLR) employing transphyseal hamstring (TPH) autograft combined with an extra-articular technique using an iliotibial band (ITB) autograft. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients undergoing combined TPH-ITB ACLR between January 2012 and April 2017 with a minimum 2-year follow-up were reviewed. With the goal of decreasing ACL graft injury in this high-risk group, this technique employed anteromedial portal drilling for TPH with an extraosseous femoral ITB technique and intra-articular TPH-ITB grafts fixed within the tibial bone tunnel. Demographics, bone age, standing alignment radiograph for growth and mechanical axis grade, return to sport, graft failure, and patient-reported outcome measures were analyzed. Results: A total of 61 knees in 60 adolescents underwent the combined TPH-ITB ACLR, with 57 knees (93.4%) meeting inclusion criteria with a mean follow-up of 38.5 months (range, 24-78 months). Only 3 of 57 knees (5.3%) sustained ACL reinjury. The mean age was 13.0 years (range, 11-16 years) with 36 male patients (mean bone age, 14.2 years) and 21 female patients (mean bone age, 13.3 years), and 91% of patients (52 of 57) returned to sport. Participants demonstrated a high functional level at final follow-up, with a mean score of 91.2 (range, 46.7-100) on the Pediatric International Knee Documentation Committee (Pedi-IKDC) Subjective Knee Evaluation Form and mean score of 22.4 (range, 4-30) on the Pediatric Functional Activity Brief Scale (Pedi-FABS). To critically assess growth, a cohort with ≥18 months of growth remaining at surgery was evaluated at maturity. No difference was seen in mean operative and nonoperative leg growth (49.7 mm and 49.8 mm). Although no family reported cosmetic or functional alignment or length concerns, 1 of 18 (5.5%) had a final limb length discrepancy >10 mm (12 mm) and a perioperative alignment difference (0-Grade II valgus). Conclusion: Combined TPH-ITB ACLR in adolescents resulted in high activity levels (Pedi-FABS, 22.4; median, 25) and a low (5.3%) graft failure rate at a mean 38.5 months.
