Background: As anterior cruciate ligament (ACL) reconstruction is performed increasingly in the United States, the rate of revision ACL reconstruction continues to rise. A paucity of literature exists with respect to repeat ACL revision surgery. Purpose: To evaluate the functional outcomes of patients who had undergone at least 2 revision ACL reconstructions. Study Design: Case series; Level of evidence, 4. Methods: The records of all patients who had undergone repeat revision ACL reconstructions between 1998 and 2009 were retrospectively reviewed. Data collected included patient demographics, operative findings, pre- and postoperative physical examination findings, radiographs, and Tegner, Lysholm, and International Knee Documentation Committee (IKDC) subjective scores. Results: Fifteen patients had undergone repeat revision ACL reconstruction during the study period. Mean age was 27 years (range, 18-57 years). Mean follow-up was 5 years (range, 2-10 years). At the time of repeat revision surgery, new tunnels were drilled in 9 of 15 (60%) cases. Of those, 8 of 9 (89%) were drilled because femoral tunnels were deemed “too anterior.” During repeat revision, 11 of 15 (73%) patients were noted to have a meniscal tear, and 9 of 15 (67%) had International Cartilage Repair Society (ICRS) grade 3 or 4 chondral lesions. Mean Lysholm score was 60 preoperatively and increased to 82 postoperatively (P < .001). Mean preoperative IKDC score was 59, which increased to 80 postoperatively (P < .001). Mean preoperative Tegner score was 6.0. Mean postoperative Tegner score was 4.5, with only 4 of 15 (27%) patients having returned to their prior activity level (P < .001). Two patients (13%) sustained a traumatic rerupture. Presence of grade 3 or 4 chondral lesions and body mass index greater than 28 at the time of repeat revision were associated with a “fair” or “poor” outcome by Lysholm score (P = .007 and P = .03, respectively) and IDKC subjective scoring (P = .04 and P = .007, respectively). Conclusion: Repeat revision ACL reconstruction may improve the functional outcomes of patients who have failed revision ACL reconstruction. Most patients do not return to prior activity level following repeat revision. Presence of grade 3 or 4 chondral lesions and body mass index greater than 28 were associated with worse outcomes.

Meniscal sparing surgery is a widely utilised treatment option for unstable meniscal tears with the aim of minimising the risk of progression towards osteoarthritis. However, there is limited data in the literature on meniscal repair outcomes in skeletally immature patients. To evaluate the re-operation rate and functional outcomes of meniscal repairs in children and adolescents. We performed a retrospective review of all patients who underwent arthroscopic meniscal repair surgery between January 2007 and January 2018. All patients were under the age of 18 at the time of surgery. Procedures were all performed by a single surgeon. Information was gathered from our hospital Electronic Patient Records system. The primary outcome measure was re-operation rate (need for further surgery on the same meniscus). Secondary outcome measures were surgical complications and patient reported outcome measures that were International Knee Documentation Committee (IKDC), Tegner and Lysholm scores. We identified 59 patients who underwent 66 All-inside meniscal repairs (32 medial meniscus and 34 Lateral meniscus). Meniscal repairs were performed utilizing FasT-Fix (Smith and Nephew) implants. There were 37 males and 22 females with an average age of 14 years (range 6-16). The average follow-up time was 53 months (range 26-140). Six patients had concomitant anterior cruciate ligament reconstruction surgery along with the meniscal repair. There were no intra-operative complications. The re-operation rate for meniscal repairs was 16.6% (11 cases) with 2 patients requiring further meniscal repairs and 9 patients underwent partial meniscectomies. The mean postoperative IKDC score was 88 (44-100), Tegner score was 7(2-10) and Lysholm score was 94 (57-100). Our results showed that arthroscopic repair of meniscal tears in the paediatric population is an effective treatment option that has a low failure rate and good postoperative clinical with the advantage of preserving meniscal tissues.

To report outcomes after combined medial patellofemoral ligament (MPFL) and medial patellotibial ligament (MPTL) reconstruction and test associations between prognostic factors and clinical outcomes. It was hypothesised that combined MPFL and MPTL reconstruction would result in significant improvement in function, and that outcomes would be associated with age, sex, Beighton score, concomitant articular lesions, and preoperative function. All combined reconstructions of MPFL and MPTL were reviewed. Inclusion criterion was minimum 2-year follow-up. Exclusion criteria were age at surgery ≥ 35years and concomitant osteotomies. Kujala, Tegner and Marx scores were completed prospectively. Patients were evaluated at a minimum 2-year follow-up. Associations between potential prognostic factors and Kujala and Tegner scores were tested using bivariate analyses followed by multivariate regression models. Of 22 patients (26 knees), 19 (23 knees) met inclusion criteria, and 16 (20 knees) were available for follow-up. Mean age at surgery was 18years (range 14.5-23). Mean follow-up was 43months (range 24-73). Postoperative Kujala score significantly improved compared to before surgery (86.4 ± 12.5 vs. 54.9 ± 15.2, p < 0.01). Postoperative Tegner score was nonsignificantly higher compared to before surgery (4.8 ± 2.4 vs. 4 ± 3, p = ns) and lower compared to before first patella dislocation (4.8 ± 2.4 vs. 5.9 ± 1.2, p < 0.01). Postoperative Kujala score was associated with male sex (p = 0.02), with medial patellofemoral chondral lesions (p = 0.01) and with preoperative Kujala score (p = 0.05). Postoperative Tegner score was associated with male sex (p < 0.01), with preoperative Tegner level (p < 0.01), and with Beighton score (p < 0.01). Patella apprehension was recorded in two knees (10%) in two patients. Combined MPFL and MPTL reconstruction in young adults results in significant improvement in subjective knee function with minimal risks, although preinjury activity levels are not consistently restored. Associated factors of improved outcome include higher preoperative knee scores and activity levels, medial patellofemoral chondral lesions, decreased Beighton scores, and male sex. This supports the advisability of the procedure and can also assist in setting realistic goals for specific groups of patients. Case series, Level IV.

Bucket-handle tears represent a subtype of meniscal injuries that involve a full-thickness longitudinal tear. These tears are challenging and demanding. The present systematic review and meta-analysis aimed to evaluate return-to-sport outcomes in young adults with isolated bucket-handle meniscal tears treated surgically through meniscal repair. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with two independent reviewers selecting studies from PubMed, Web of Science, and Scopus databases. Studies were included if they involved patients over 16 years old, with isolated bucket-handle tears, a minimum of one-year follow-up, and reported postoperative Tegner scores. Five studies comprising 168 individual knees met these criteria and were analyzed. Quality assessment employed the Newcastle-Ottawa Scale. Data analysis was conducted in R(R Foundation for Statistical Computing, Vienna, Austria) for pooled outcome calculations. The primary outcome was the postoperative Tegner score, representing a return to sports; secondary outcomes included changes in Tegner and Lysholm scores and failure rates. Two cohort studies and three case series were included, with quality ratings ranging from fair to poor. The mean patient age was 27.8 years, and the mean follow-up was 82.4 months. The pooled postoperative Tegner score was 5.94 (95% CI: 5.41-6.46), indicating a high return to recreational sports. The mean change in Tegner score was 2.48 (p = 0.0604), which was not statistically significant, while Lysholm score improvement was significant at 31.16 points (p = 0.0093). The pooled failure rate across studies was 14% (95% CI: 0-42%). Patients with isolated bucket-handle meniscal tears undergoing surgical repair demonstrate a high rate of return to recreational sports, with significant improvements in Lysholm scores. However, failure rates and study quality variability suggest further high-quality research to make safer conclusions.

<h3>Objectives</h3> To compare the outcomes between autograft and allograft reconstruction in patients with PCL deficiency. During the extraction of data and its comparison and interpretation in the development of this meta-analysis, the lack of standardisation in patient follow-up with regards to length of follow-up, modalities measured, and reports of adverse events were notable. Many studies were thus excluded due to failure to meet preset inclusion criteria. The subsequent data analysis therefore became limited in its translation towards guiding clinical and surgical practice. The development of a standardised pre and post-operative assessment and follow-up criteria will not only benefit patients, but will also ensure that future systematic reviews conducted will carry a higher impact towards guiding clinical practice. <h3>Method</h3> Medline, EMBASE, and the Cochrane Library databases were searched from January, 1980 until December 1 st, 2016 to identify all relevant articles. Clinical outcomes including International Knee Documentation Committee (IKDC), Tegner and Lysholm scores, joint laxity and posterior tibial displacement were evaluated. Dichotomous outcomes were pooled into odds ratios while continuous outcomes were pooled into weighted mean differences (MD) using random effects meta-analysis. <h3>Results</h3> We conducted a systematic review looking at outcomes of isolated PCL reconstruction comparing autograft vs allograft sources. Clinical outcomes including International Knee Documentation Committee (IKDC), Lysholm and Tegner scores, joint laxity, and posterior tibial displacement were evaluated. Amongst the 145 unique articles found through the screening process, 25 studies, with a combined patient population of 900, were deemed eligible for inclusion in this study. Post-operative improvement was observed regardless of graft source. Pooled findings revealed that autografts demonstrated a statistically significant post-operative activity as measured by Tegner scores (MD: 0.5, 95% CI 0.03, 0.9; p=0.04) and a reduced posterior laxity (MD: −1.2, 95% CI −1.6,–0.8; p&lt;0.00001). <h3>Conclusions</h3> However, despite a statistically significant improvement, there is difficulty establishing a clinically significant improvement. This stems from the absence of a standardised guideline of measuring pre-operative and post-operative functions. One example is the inconsistent usage of IKDC scores between studies, a failure of reporting both pre and post-operative IKDC scores, and subjective reporting as either ‘normal’ or ‘abnormal’ rather than following a protocol. Thus, the development of a systematic approach to assess patients before and after operations, along with establishment of an agreed minimally clinical important difference will lend to more impactful data analysis and ease of generating guidelines.

Background:Injury to the quadriceps tendon is rare and most commonly occurs in middle-aged men. Few reports are available regarding outcomes after quadriceps tendon rupture in younger patients.Purpose/Hypothesis:To review the clinical outcomes of patients who underwent quadriceps tendon repair at age ≤40 years. We hypothesized that this cohort would experience better clinical outcomes in comparison to historical older controls.Study Design:Case series; Level of evidence, 4.Methods:Using an institutional database, we retrospectively identified patients who underwent quadriceps tendon repair between January 2009 and December 2017. Patients were included in the study if they were aged ≤40 years at the time of surgery and had sustained an isolated, complete tendon rupture. Patient and injury characteristics were recorded. Patients were contacted to complete a custom survey, the 2000 International Knee Documentation Committee (IKDC) form, the Lysholm scale, and the Tegner scale.Results:Included were 38 patients (86.8% male; mean age, 32.0 ± 6.9 years; age range, 15-40 years), with a mean follow-up of 5.9 ± 2.3 years (range, 2.4-11.3 years). At final follow-up, the mean IKDC score was 74.1 ± 22.6 (range, 26.4-100.0), and the mean Lysholm score was 85.4 ± 20.0 (range, 30-100), which were similar if not inferior to historical controls of patients >40 years. Only 16 patients (42.1%) had unchanged or higher Tegner scores after surgery, whereas 22 patients (57.9%) reported lower postoperative activity level. Overall, 91.2% (31/34) of workers returned at a mean 3.9 months after surgery, whereas 63% (12/19) of athletes were able to return to play at 8.8 months. At final follow-up, 12 patients (31.6%) reported persistent pain and stiffness in their knees. Additionally, 3 patients (7.9%) reported pain without stiffness, and 4 (10.5%) reported stiffness without pain. Patients reporting pain or stiffness had significantly lower IKDC scores, Lysholm scores, postoperative Tegner scores, and change in their Tegner score at final follow-up in comparison to those who did not report pain or stiffness.Conclusion:Although patients aged ≤40 years had satisfactory outcomes after quadriceps tendon repair, this injury resulted in significant long-term sequelae in a substantial percentage of patients, despite their youth. Further, this group did not have better outcomes compared with historical controls aged > 40 years.

Arthroscopic Reconstruction of the Posterior Cruciate Ligament With Use of a Quadruple Hamstring Tendon Graft With 3- to 5-Year Follow-up

Recurrent patellar dislocation is a frequent knee disorders in young, active patients. Medial patellofemoral ligament reconstruction (MPFLR) can restore knee stability and function, but the rate of return to sports is less clear. The aim of this study was to evaluate rate of return to sport following treatment of recurrent patellar dislocation with isolated MPFLR. Between 2011 and 2018, 113 patients with recurrent patellar dislocation were treated with isolated MPFLR at an academic center. Pre-injury sports participation and Tegner score, pre-operative subjective IKDC score, time to return to sports, and post-operative Tegner and subjective IKDC scores were collected, with a minimum of follow-up of 2years. One hundred and three patients (91%) were evaluated at a mean of 4.5 ± 2.5-year post-operative. 92 patients (89%) participated in sports prior to onset of patellar instability. At final follow-up, 84 of these 92 patients (91%) were able to return to sports. The mean time from surgery to return to sports was 10.4 ± 8.6months (range: 2-48months). 62 patients (67%) returned to the same (50 patients) or higher (12 patients) level. 22 patients (26%) returned at a lower level. 19 of these patients attributed this decreased participation to ongoing knee problems. The median Tegner score was noted to decrease from 5 pre-injury to 4 post-operatively (p = 0.02). Isolated MPFL reconstruction allowed return to pre-injury sports in 91% of patients, with 67% of patients returning to the same or higher level than pre-injury. Mean time to return to sports was 10months and post-operative Tegner score was noted to be modestly decreased from pre-injury level. IV.

Background:Despite marked improvements in stability after lateral ankle ligament repair, many patients do not return to their preinjury activity level. There are few studies addressing athletes’ assessment of their ability to return to play after lateral ankle ligament reconstruction for recurrent instability.Purpose:To determine the rate of return to the preinjury activity level among physically active patients after the modified Broström procedure (MBP) for recurrent lateral ankle instability.Study Design:Case series; Level of evidence, 4.Methods:Included were patients who had undergone a primary MBP by a single surgeon over a 6-year period and had a minimum 24 months of follow-up. A telephone questionnaire was conducted to ascertain the patient’s ability to return to sport and/or work activity at final follow-up. Activity levels were evaluated utilizing the Tegner activity score. Outcome scores and other measured variables were compared between patients who returned to their preinjury level and those who did not. The reasons for failing to return were also documented.Results:Of the 59 patients who met the inclusion criteria, 41 (69%; 20 men and 21 women) participated in the telephone interview. Results indicated that 22 (54%) returned to their prior level of activity (returners). The mean age of returners was 27.2 years; for nonreturners, the mean age was 27.1 years. Most patients (36/41; 88%) were satisfied with surgery and the overall outcome. Of the 19 nonreturners, 7 (37%) noted ankle-related reasons for not returning (pain: 57%; residual instability: 29%; decreased range of motion: 14%), and 12 (63%) cited non–ankle-related reasons. The mean preinjury and postoperative Tegner score for returners was 6.8. Moreover, 7 of 14 (50%) high-level athletes with preinjury Tegner scores ≥8 returned to their preinjury activity level. For high-level athletes who did not return to their previous level, the mean postoperative Tegner score was 6.6, and only 1 (7%) cited an ankle-related reason for not returning.Conclusion:A high patient satisfaction rate was reported after the MBP for recurrent lateral ankle instability. The majority of patients who did not return to their preinjury level cited a non–ankle-related factor as the reason for not returning to sport. This was especially true for the higher level athletes.

This retrospective case series describes a hybrid fixation technique and determines the clinical outcomes, knee function, and activity level of patients at short-term follow-up. Seventeen patients (18 knees) with unstable osteochondritis dissecans (OCD) lesions involving the knee were treated with a hybrid fixation technique in which the salvageable fragment was fixed and osteochondral autograft transplantation system (OATS) was used for the unsalvageable fragment. Thirteen lesions involved the medial femoral condyle, 4 involved the lateral femoral condyle, and 1 involved the patella. Mean patient age was 17 years (range 12-28 years). All lesions were International Cartilage Repair Society (ICRS) grade III or IV. The patients were prospectively followed postoperatively. Outcome measures included the International Knee Documentation Committee (IKDC) score, Knee injury and Osteoarthritis Outcome Score (KOOS), and the Tegner activity scale. At mean follow-up of 36 months (range 24-67.2 months), the mean postoperative KOOS scores, given as mean (SD), were as follows: Quality of Life (QoL) 91.1 (17.0), Activities of Daily Living (ADL) 99.5 (1.5), Sport 94.5 (11.2), Pain 97.4 (5.8), and Symptoms 95.9 (6.5). Mean IKDC score was 96.2 (7.0). There was no significant difference between mean preinjury (7.95, SD = 1.1) and mean postoperative (7.45, SD = 1.5) Tegner scores (P = 0.363). The mean Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score was 87.5 at a mean 7.8 months (range 3-18 months) postoperation. There were no reported complications. The results of this case series suggest that patients with partially salvageable OCD lesions involving the knee can have positive short-term outcomes and can expect a low complication rate when treated with a hybrid technique of fixation with osteochondral autograft transfer.

It is unclear whether the biomechanical superiority of the inlay technique over the transtibial technique, arising from avoidance of the killer turn at the graft-tunnel margin of the proximal tibia during posterior cruciate ligament (PCL) reconstruction, leads to better knee scores or greater knee stability. This systematic review was designed to compare Tegner and Lysholm scores, and posterior residual laxity of the knee, between single-bundle PCL reconstruction using transtibial and inlay techniques. We searched MEDLINE®, Embase®, and the Cochrane Library for studies comparing Tegner and/or Lysholm scores and posterior residual laxity, in patients who underwent PCL single-bundle reconstruction with the transtibial and tibial inlay techniques. There were no restrictions on language or year of publication. Studies were included if they compared clinical outcomes in patients who underwent PCL single-bundle reconstruction with the transtibial and tibial inlay techniques; they simultaneously reported direct comparisons of transtibial and tibial inlay PCL single-bundle reconstruction; and their primary outcomes included comparisons of postoperative scores on knee outcome scales and posterior residual laxity. A total of seven studies (including 149 patients having surgery using a transtibial approach, and 148 with the tibial inlay approach) met the prespecified inclusion criteria and were analyzed in detail. Our systematic review suggested that there are no clinically important differences between the transtibial and the tibial inlay single-bundle PCL reconstruction in terms of Tegner or Lysholm scores. Of the five studies that assessed Lysholm scores, one favored the transtibial approach and four concluded no difference on this endpoint; however, the observed differences in all studies where differences were observed were quite small (< 7 of 100 points on the Lysholm scale), and likely not clinically important. Of the four studies that compared postoperative Tegner scores, three identified no differences between the approaches, while one favored the tibial inlay approach by a small margin (0.5 of 11 points) suggesting that there likely is no clinically important difference between the approaches in Tegner scores, either. Finally, we identified no difference between the approaches in terms of residual laxity, either among the seven studies that presented data using Telos radiographs, or the five that reported on patients with residual laxity greater than Grade 2 on a four-grade scale of posterior drawer testing (28/107 for transtibial and 26/97 for tibial inlay). We found no clinically important differences between the transtibial and tibial inlay approach for PCL reconstruction. Based on the best evidence now available, it appears that surgeons may select between these approaches based on clinical experience and the specific elements of each patient's presentation, since there do not appear to be important or obvious differences between the approaches with respect to knee scores or joint stability. Future randomized trials are needed to answer this question more definitively. Level III, therapeutic study.
