Introduction: Current incidence of recurrent anterior cruciate ligament (ACL) instability is 5%, but revision surgery is challenging and requires a thorough analysis of potential risk factor. Moreover, recurrent and chronic ACL instability can result in medial tibio-femoral osteoarthritis (OA). Beside various soft tissue patterns, bony morphologies like a steep posterior tibial slope are associated with an increased anterior tibial translation (ATT) and rotatory instability in the ACL deficient knee. To address the instability and the osteoarthritis a combined procedure is necessary in these patients, however, little is known about the efficacy of such combined procedures. Therefore, the objective of this study was to evaluate the patient reported outcomes and knee stability following combined high tibial osteotomy (HTO) with ACL reconstruction in middle-aged patients with recurrent or chronic cruciate ligament deficiency and mild to moderate medial compartment osteoarthritis (OA). Hypotheses: Methods: Surgical reports and prospectively collected patient reported outcome scores (IKDC, Lysholm, WOMAC, VAS for pain, and Tegner activity score) as well as clinical examination were evaluated retrospectively with a mean follow up of 45.2 ± 14.7 months. Inclusion criteria were 1) high tibial osteotomy with concomitant anatomic ACL reconstruction. Data at final followup were compared to baseline values using the Wilcoxon signed rank test (p < 0.05). Results: 44 patients met the inclusion criteria. 16/44 suffered a graft failure after primary ACL reconstruction, and 8/44 had chronic ACL instability, but had a previous subtotal medial meniscus resection. Mean patient age at surgery was 38.2 ± 10.5 years (range: 18 – 63) with a mean varus alignment of 4.5° ± 1.5°. All patient reported significantly improved outcome scores at final follow-up (VAS 4.3 to 1.5, Lysholm 52.4 to 73.5, IKDC 56.5 to 70.9). However, the change in Tegner score at final follow-up (3.4 to 4.5) was not significant. At final followup 25/44 patients had a removal of the fixation plate. Conclusion: The results of this study indicate, that high tibial osteotomy combined with anatomic single bundle ACL reconstruction is a good treatment option in active middle aged patients suffering from recurrent or chronic ACL deficiency with mild to moderate medial compartment OA. At a median follow-up of 24 months patient reported outcome scores were improved. Especially in patients with multiple ACL reconstruction failures realignment osteotomies should be considered.

Surgical Data

Objectives: Revision anterior cruciate ligament (ACL) reconstruction remains a challenge for orthopaedic surgeons, as results are persistently inferior to those of primary reconstructions. There is very limited data regarding outcomes at 6 years following revision ACL surgery. The purpose of this study was to report the rate of reoperation, further revision, and conversion to total knee arthroplasty (TKA) in a large cohort of revision ACL reconstructions Methods: Patients undergoing revision ACL reconstructions were identified and prospectively enrolled between 2006 and 2011. Data collected included baseline demographics, intraoperative surgical technique, and a series of validated patient-reported outcome instruments. Patients were followed up by questionnaire and telephone at 6 years following index revision surgery and asked if they had undergone any further surgical procedures to either knee. If a patient reported having undergone subsequent surgery, operative reports detailing the subsequent procedure(s) were obtained and categorized. Results: Six-year follow-up subsequent surgical data was available for 951/1234 patients (77%). In this available cohort, 556 (58%) were male, mean age was 28 years (range 12-61 years) and mean BMI was 26.1 (range 17.1-47.5). Allograft was used in 510 (54%) cases, BTB autograft in 234 (25%), soft tissue autograft in 174 (18%) and other grafts were used in the remaining 33 (3%). Their index surgery was their first revision ACL reconstruction in 822 (86.4%), in 108 (11.4%) it was their second, and in 21 (2.2%) it was their third or greater. This revision procedure was a mean of 5.7 years (range 0.1-26 years) from their prior ACL reconstruction. At six years following the index revision procedure, 16.2% of the cohort underwent at least 1 subsequent surgical procedure on their index knee. Of the reoperations, 29% were meniscal procedures (71% meniscectomy, 18% repair), 21% were articular cartilage procedures (79% chondroplasty, 15% microfracture, 3% OATS, 3% ACI), 11% were for arthrofibrosis, 9% for hardware removal, and 6% were for a subsequent revision ACL reconstruction. Surprisingly, only 5% reported having undergone a subsequent TKA on their ipsilateral knee. During this same 6-year follow-up period, 6% of the cohort (n=53 patients) underwent a subsequent surgery on their contralateral knee, of which 36 were ACL reconstructions. Conclusion: Our data shows that there is a reoperation rate of greater than 15% following ACL revision, which is an important point of discussion between surgeons and their patients. Of particular interest is that there was a 6% rate of recurrent ACL failure and 5% rate of subsequent TKA in this young cohort 6 years following a revision ACL reconstruction.

Background: Meniscal and chondral lesions are commonly associated with anterior cruciate ligament (ACL) tears, and these lesions may play a role in patient outcomes after ACL reconstruction. Purpose: To determine the effects of the presence and location of meniscal and chondral lesions at the time of ACL reconstruction on patient-reported outcomes at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with no prior knee surgery who underwent primary ACL reconstruction by a single surgeon between 2010 and 2014 were included in this study. Those meeting inclusion criteria were divided into the following groups based on the arthroscopic diagnosis: patients without concomitant meniscal or chondral lesions, patients with isolated meniscal lesions, patients with isolated chondral lesions, and patients with both chondral and meniscal lesions. Patient-reported outcomes (Short Form–12 [SF-12] physical component summary [PCS] and mental component summary [MCS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], and Lysholm scale) were assessed at a minimum of 2 years from the index surgery. Results: A total of 151 patients met the inclusion criteria and were included in the study. The mean age at the time of surgery was 36.2 years (range, 14-73 years), and the mean follow-up was 3.2 years (range, 2.0-5.6 years). At the time of surgery, 33 (22%) patients had no concomitant lesions and served as the control group, 63 (42%) patients had isolated meniscal lesions, 21 (14%) patients had isolated chondral lesions, and 34 (22%) patients had both chondral and meniscal lesions. There was significant improvement in all outcome scores postoperatively for the 3 groups ( P < .05 for all outcome scores). The presence of a meniscal tear and laterality of the meniscal lesion did not have a negative effect on any postoperative outcome scores. Patients with isolated chondral lesions had significantly lower postoperative WOMAC scores compared with patients without chondral lesions ( P < .05). No significant differences were found for all other scores. Patients with patellofemoral chondral lesions had significantly lower postoperative SF-12 PCS and Lysholm scores than patients with tibiofemoral chondral lesions ( P < .05). Conclusion: Patients with ACL tears achieved improved functional scores at a mean 3.2 years after ACL reconstruction. While meniscal lesions did not affect postoperative outcomes in the short term, chondral lesions were identified as a predictor for worse outcomes.

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: There is no consensus regarding the best treatment approach for skeletally immature children with anterior cruciate ligament (ACL) injuries. High-quality studies with long-term follow-up are lacking, and evidence to support decision making is limited. Purpose: To evaluate functional and patient-reported outcome, surgical history, and complications among young adults who sustained an ACL injury before the age of 13 years and were treated with active rehabilitation and the option of delayed ACL reconstruction if needed. Study Design: Case series; Level of evidence, 4. Methods: Forty-six children aged <13 years with a total intrasubstance ACL injury were included. None of these patients had additional injuries that warranted early surgery. At final follow-up at a mean 8 years after the time of injury, 44 patients remained in the study. The same test battery was conducted at baseline, 1 and 2 years, and final follow-up at approximately 18 years of age. The test battery included functional tests (hop tests and isokinetic muscle strength tests of quadriceps and hamstrings), patient-reported outcome measures (including the Knee injury and Osteoarthritis Outcome Score and the International Knee Documentation Committee Subjective Knee Form), and clinical examination. Medical records were reviewed to assess surgical history and complications. Results: At a mean 8 years of follow-up, 24 patients (55%) had undergone ACL reconstruction, and 16 (36%) had undergone meniscal surgery. Quadriceps muscle strength symmetry was >90% for 30 patients (68%). Mean leg symmetry indexes for hop and strength tests were consistently >90%, except for the single-hop test and hamstrings muscle strength for ACL-reconstructed knees. Mean ± SD International Knee Documentation Committee scores were 86.3 ± 13.7 for the ACL-reconstructed knees and 90.6 ± 11.8 for the nonreconstructed knees. At final follow-up, forty patients (91%) remained active in sports, but 29 (66%) restricted their activity level to nonpivoting sports. Conclusion: Active rehabilitation may have a role in treatment of children with ACL injury. Approximately 50% of children may cope well, even to adulthood, without a surgical intervention. The other half may develop instability that warrants ACL reconstruction, and one-third may require meniscal surgery.

Background: Quadriceps tendon (QT)–bone autografts used during anterior cruciate ligament (ACL) reconstruction have provided comparable outcomes and decreased donor-site morbidity when compared with bone–patellar tendon–bone (BPTB) autografts. No study has directly compared the outcomes of the all–soft tissue QT autograft with that of the BPTB autograft. Hypothesis: Patient-reported knee outcome scores and rates of postoperative complication after primary ACL reconstruction with QT autografts are no different from BPTB autografts at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 75 patients who underwent primary autograft ACL reconstruction with QT or BPTB autografts between January 1, 2015, and March 31, 2016, at a single hospital center were contacted by telephone and asked to complete the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation, Tegner activity level scale, and Lysholm knee scoring scale. Information about the subsequent surgeries performed on the operative knee was also collected. Statistical analysis was performed using the Kruskal-Wallis test and the Fisher exact test for categorical data. Results: Fifty patients (28 QT, 22 BPTB) completed the surveys at a mean follow-up of 33.04 months (range, 24-44 months). For the QT versus the BPTB group respectively, the median IKDC scores were 94.83 (interquartile range [IQR], 7.61) versus 94.83 (IQR, 10.92) ( P = .47), the median Tegner scores were 6 (IQR, 2.5) versus 6 (IQR, 2.75) ( P = .48), and the median Lysholm scores were 95 (IQR, 9) versus 95 (IQR, 13) ( P = .27). Additionally, 2 QT patients and 3 BPTB patients required follow-up arthroscopy for arthrolysis ( P = .64). There was 1 graft failure in the QT group requiring revision surgery. Conclusion: There was no statistical difference in patient-reported knee outcomes or graft complication rates between the QT and BPTB autograft groups at a minimum 2-year follow-up after primary ACL reconstruction. This study highlights that the all–soft tissue QT autograft may be a suitable graft choice for primary ACL reconstruction.

AbstractThe objective of this study was to provide a comprehensive systematic review and meta-analysis to compare patient-reported outcomes and functional knee parameters of anterior cruciate ligament (ACL) reconstruction surgery with semitendinosus (ST) and ST-gracilis (G) grafts. This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines. All studies in PubMed and Embase that reported functional knee parameters and patient-reported outcomes after ACL reconstruction with ST and ST-G grafts independently were included in the review. Selected end points for random effects, pairwise meta-analysis included side-to-side deficit (%) in isokinetic peak torque, peak torque ratio (%), side-to-side difference (mm) in anterior laxity, and patient-reported outcome scores at minimum 2-year follow-up. A total of 15 primary references comprising 1,109 participants were identified. The ST group had decreased side-to-side deficit in isokinetic peak torque when compared with the ST-G group for flexion at 60 degrees/s (p = 0.02) and 180 degrees/s (p = 0.01) at 2-year follow-up. There were no significant differences in side-to-side difference in anterior laxity (p = 0.81), hamstring/quadriceps peak torque ratios at 60 degrees/s (p = 0.83) and 180 degrees/s (p = 0.36), and patient-reported outcomes in the International Knee Documentation Committee score (p = 0.06) and Lysholm score (p = 0.67). The addition of the gracilis tendon to the hamstring autograft in ACL reconstruction results in increased side-to-side deficits in isokinetic peak flexion torque. However, patient-reported outcome scores and knee laxity measurements are comparable with those of ST grafts.

Objectives: There is a general consensus that Jones fractures should be treated operatively with an intramedullary screw in high-level athletes. However, there is disagreement among team physicians, without conclusive evidence as to when the athlete should be allowed to return to play. The objective of this study is to report our experience of early return to sport in collegiate athletes after intramedullary screw fixation of Jones Fractures. Methods: All skeletally mature collegiate athletes with a true Jones fracture of the base of the fifth metatarsal that was treated by one of two orthopaedic surgeons with operative intramedullary screw fixation over a 23 year period (1994-2016) were identified and records reviewed retrospectively. All return to play and complication data was obtained from the athletic trainer database at the two universities. Fixation consisted of a single intramedullary screw (10 partially threaded cannulated screws, 13 cannulated variable pitch screws, 3 solid screws). The athletes were allowed to weight bear as tolerated in a CAM boot immediately postoperatively, and return to play with a carbon fiber insert as soon as they could tolerate activity. In 2016, patients were contacted to complete patient reported outcome scores that included the Foot and Ankle Ability Measure (FAAM) score and a brief survey specific to our study, as well as follow-up radiographs if possible. Results: 26 Jones Fractures were treated in 25 collegiate athletes. The average age was 20 years (18-23). Overall, athletes returned to play or training at an average of 3.5 weeks (1.5-6). All in-season athletes returned to play within 4.5 weeks (1.5-4.5). Off-season athletes returned to play within 4-6 weeks. There were no cases of nonunion (clinically or radiographically). Three screws were removed due to symptomatic skin irritation. There was one re-fracture following screw removal after documented radiographic and clinical fracture union. This patient was treated with repeat cannulated percutaneous screw fixation. The athlete returned to play in 2 weeks. One screw was noted to be broken on an ankle radiograph 1 year post-op, but the fracture was healed and the athlete was playing division 1 sports without symptoms, and continued professionally without symptoms. 18/25 athletes completed patient reported outcome scores at an average of 7.95 years (range 1.2-17) follow-up. The average estimated percent of normal for activities of daily living was 93.8% (70-100%, and for athletic participation was 90.3% (40-100%). Follow up radiographs were obtained on 13/26 fractures at an average of 6.48 years (range 1.2-16) with no nonunion, malunion, or additional hardware complications identified. Conclusion: Athletes with Jones fractures can safely be allowed to return to play after intramedullary screw fixation as soon as their symptoms allow without significant complications. In our experience, this is usually within 4 weeks from injury.

Background: Several long-term (≥20 years) follow-up studies after anterior cruciate ligament (ACL) reconstruction have been published in recent years, allowing for a systematic evaluation of outcomes. Purpose: To summarize outcomes at ≥20 years after ACL reconstruction and identify patient and surgical factors that affect these results. Study Design: Systematic review; Level of evidence, 4. Methods: Prospective studies of primary ACL reconstructions with hamstring or bone–patellar tendon—bone (BTB) autograft via an arthroscopic or a mini-open technique and with a mean follow-up of ≥20 years were identified. When possible, the mean scores for each outcome measure were calculated. Factors identified in individual studies as predictive of outcomes were described. Results: Five studies met the inclusion and exclusion criteria with a total of 2012 patients. The pooled mean follow-up for patient-reported outcome measures was 44.2% (range, 29.6%-92.7%) and in-person evaluation was 33.2% (range, 29.6%-48.9%). Four studies (n = 584) reported graft tears at a mean rate of 11.8% (range, 2%-18.5%) and 4 studies (n = 773) reported a contralateral ACL injury rate of 12.2% (range, 5.8%-30%). Repeat non-ACL arthroscopic surgery (4 studies; n = 177) to the ipsilateral knee occurred in 10.4% (range, 9.5%-18.3%) and knee arthroplasty (1 study; n = 217) in 5%. The pooled mean of the International Knee Documentation Committee subjective knee function (IKDC) score was 79.1 (SD, 21.8 [3 studies; n = 644]). In 2 studies (n?= 221), 57.5% of patients continued to participate in strenuous activities. The IKDC-objective score was normal or nearly normal in 82.3% (n = 496; 3 studies), with low rates of clinically significant residual laxity. Moderate-severe radiographic osteoarthritis (OA) (IKDC grade C or D) was present in 25.9% of patients (n = 605; 3 studies). Medial meniscectomy is associated with increased risk of radiographic OA. Radiographic OA severity is associated with worse patient-reported knee function, but the association with knee pain is unclear. Conclusion: Currently available prospective evidence for ACL reconstruction with hamstring or BTB autograft provides several insights into outcomes at 20 years. The rates of follow-up at 20 years range from 30% to 93%. IKDC-objective scores were normal or nearly normal in 82% and the mean IKDC-subjective score was 79 points.

Clinical Stability

Background: The short-term outcomes of anterior cruciate ligament (ACL) reconstruction with bone–patellar tendon–bone or hamstring tendon (HT) graft are excellent with good clinical stability and patient-reported outcomes. Although some studies have reported the long-term outcomes of bone–patellar tendon–bone graft ACL reconstruction, few have reported the outcomes of HT graft ACL reconstruction. Purpose: To assess clinical and radiographic outcomes of HT graft ACL reconstruction with femoral cortical button fixation at a minimum 20-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: A prospective study was performed in which all patients undergoing isolated transtibial primary ACL reconstruction between 1994 and 1996 with HT graft and femoral cortical button fixation were assessed clinically and radiographically. Follow-up was obtained in 48 of 94 patients (51%). Median (interquartile range) age at operation was 31 years (26-39 years); median follow-up was 21 years (20-22 years); 65% were male; and 48% had meniscal injury at surgery and underwent partial meniscectomy. Graft rupture, reoperation, and contralateral injury rates were assessed; clinical stability was measured using the KT-1000 arthrometer; patient-reported outcomes were assessed (International Knee Documentation Committee [IKDC], Lysholm, Forgotten Joint Score, Tegner activity, Knee injury and Osteoarthritis Outcome Score [KOOS], Anterior Cruciate Ligament Quality of Life [ACL-QOL], EuroQol 5-Dimension 5-Level [EQ-5D-5L]); and radiographic osteoarthritis (defined as Kellgren-Lawrence grade ≥2) was assessed for the ipsilateral and the contralateral knee. Results: Graft rupture occurred in 4 patients (8%), contralateral injury in 4 patients (8%), and reoperation in 15 patients (31%), which consisted mainly of meniscal tears or hardware removal. In patients with an intact graft, excellent patient-reported outcome measures (PROMs) were noted, with a median Lysholm of 90 (78-100), subjective IKDC of 86 (72-95), and KOOS–Sports of 86 (58-100). There was low awareness of the operated knee (Forgotten Joint Score, 81 [60-96]) and good quality of life (ACL-QOL, 85 [75-94]; EQ-5D-5L, 0.87 [0.83-1.00]). Median side-to-side difference, as measured with the KT-1000 arthrometer, was 1 mm (-1 to 3 mm). Radiographic osteoarthritis was evident in 49% of ipsilateral and 10% of contralateral knees and was associated with meniscectomy at index surgery and decreased PROMs at follow-up. Conclusion: Long-term outcomes of transtibial HT graft ACL reconstruction with femoral cortical button fixation are generally good with a low failure rate, low awareness of the operated knee, and good clinical stability. Radiographic osteoarthritis was evident in approximately half of the patients at 20-year follow-up and was associated with meniscectomy at index surgery and decreased PROMs at follow-up.

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.
