Abstract Purpose: Despite various challenges, orthopaedic sports surgeons are still providing the arthroscopic service in developing countries like Nepal; however, it is hardly being reported. The main purpose of this study was to compare the clinical outcomes and complications of patients undergoing arthroscopic ACLR in the Urban group and that of the Rural group. Methods: We evaluated a total of 194 patients, including 98 patients in the Urban group and 96 patients in the Rural group, undergoing arthroscopic ACLR between August 2015 and February 2018. The subjective evaluations were performed using the Tegner-Lysolm score and International Knee Documentation Committee (IKDC) form. The laxity assessments were performed using the Lachman test and the Pivot-shift test. The functional evaluation included the ROM, single-leg hop test, and overall IKDC score. Radiological assessment was performed according to the IKDC guidelines. SPSS was used for data analysis. Results: There was statistically significant differences in the subjective assessments between 2 groups. No statistically significant differences existed between 2 groups in terms of Laxity and Functional assessments. However, the proportion of laxity, in terms of Lachman test and Pivot-shift test, was higher in the young and active individuals and the proportion of abnormal and severely-abnormal in all parameters of functional outcomes was higher in the older female in the Rural group. Graft failure occurred in 19(17.6%) knees in the Urban group and 17(16.8%) knees in the Rural group. Graft failure in the urban group was higher in young and active male patients, whereas failure in the Rural group was more in female patients. Similarly, overall infection occurred in 13 (6.2%) knees, including 5 (2.3%) deep infections and 8 (3.8%) superficial infections. Conclusion: We advised the similar rehabilitation protocol for all the patients; however, the outcomes were significantly lower in patients living in rural areas as they are found to have poor compliance with the rehabilitation protocol. The overall graft failure rate was 17.2%; however, the reoperation rate was higher in the Urban group than the Rural group. The rate of deep infection was higher in the Rural group as compared to the Urban group.

This study compared clinical outcomes obtained after single-bundle anterior cruciate ligament (ACL) reconstruction using the anteromedial (AM) and transtibial (TT) techniques, which comprise the conventional transtibial (cTT) and modified transtibial (mTT) techniques. This study included clinical randomized controlled trials and prospective and retrospective controlled trials with AM and TT techniques from the PubMed and Embase databases and the Cochrane Library. All databases were searched from January 2010 to July 2020. Two independent evaluators verified the quality of the included studies using the Cochrane Collaboration’s risk of bias tool and the Newcastle-Ottawa Scale (NOS). Outcome measures analysed included the Lachman test, pivot-shift test, side-to-side difference (SSD), Lysholm score, Tegner activity scale, International Knee Documentation Committee (IKDC) grade and score. Ten randomized controlled trials (RCTs) and 16 prospective and retrospective controlled trials were included with a total of 2202 patients. There were 1180 patients and 1022 patients in the AM and TT groups, respectively. Compared to the cTT group, superior postoperative results were observed in the AM group based on the negative rate of the Lachman test and the pivot-shift test, IKDC grade and score, Lysholm score, Tegner activity scale and SSD (p < 0.05). However, there was no significant difference between the AM and mTT groups (p > 0.05). Compared to the conventional TT technique, the AM technique exhibited superior clinical outcomes. Nevertheless, the modified TT and AM techniques had comparable results. With neither of the techniques (mTT or AM) producing significantly superior outcomes, surgeons can choose either of them depending on their preferences.

Background: Bone–patellar tendon–bone (BPB) autografts and hamstring tendon (HT) autografts are 2 popular choices for anterior cruciate ligament reconstruction (ACLR). Although existing meta-analyses have explored the clinical outcomes between BPB and HT autografts, none have based their analysis on studies with just femoral suspensory fixation methods. Purpose: To evaluate and compare clinical outcomes, particularly graft failure and knee stability, of ACLR with BPB or HT autografts with suspensory femoral fixation. Study Design: Systematic review; Level of evidence, 4. Methods: A literature search was conducted of studies reporting single-bundle ACLR with BPB autografts and HT autografts with suspensory fixation with a minimum 24-month follow-up. Graft failure rate, knee stability, and clinical outcomes were compared for BPB versus HT autografts. Knee stability was measured with the Lachman test, pivot-shift test, and KT-1000/2000 arthrometer side-to-side difference (SSD). Clinical outcomes were measured with Lysholm scores and the Tegner activity scale, as well as rate of return to preinjury sports. Donor site morbidity among included studies was reviewed. A random-effects model was used for calculations of summary estimates. Subgroup, sensitivity, and trial sequential analyses were conducted. Results: Five studies were included. Graft failure was seen more often in the HT group than the BPB group, and this was statistically significant ( P = .03). However, the trial sequential analysis outcome indicated that the included sample size was not large enough to support a solid positive finding. The analysis showed no significant difference in SSD, Lachman test, pivot-shift test, rate of return to sports, Lysholm score, or Tegner score between groups. Subgroup analyses found no significant difference between groups. Conclusion: This meta-analysis demonstrated no significant differences in knee stability and knee functional outcomes between BPB and HT autografts with suspensory fixation. More evidence is needed to prove the lower risk of failure with use of BTB autograft with suspensory fixation.

Background: Comprehensive studies evaluating quadriceps tendon (QT) autograft for anterior cruciate ligament (ACL) reconstruction are lacking. The optimal choice of graft between bone–patellar tendon–bone (BPTB), hamstring tendon (HT), and QT is still debatable. Hypothesis: The current literature supports the use of QT as a strong autograft with good outcomes when used in ACL reconstruction. Study Design: Meta-analysis; Level of evidence, 2. Methods: A systematic search of the literature was performed in PubMed, MEDLINE, Cochrane, and Ovid databases to identify published articles on clinical studies relevant to ACL reconstruction with QT autograft and studies comparing QT autograft versus BPTB and HT autografts. The results of the eligible studies were analyzed in terms of instrumented laxity measurements, Lachman test, pivot-shift test, Lysholm score, objective and subjective International Knee Documentation committee (IKDC) scores, donor-site pain, and graft failure. Results: Twenty-seven clinical studies including 2856 patients with ACL reconstruction met the inclusion criteria. Comparison of 581 QT versus 514 BPTB autografts showed no significant differences in terms of instrumented mean side-to-side difference ( P = .45), Lachman test ( P = .76), pivot-shift test grade 0 ( P = .23), pivot-shift test grade 0 or 1 ( P = .85), mean Lysholm score ( P = .1), mean subjective IKDC score ( P = .36), or graft failure ( P = .50). However, outcomes in favor of QT were found in terms of less donor-site pain (risk ratio for QT vs BPTB groups, 0.25; 95% CI, 0.18-0.36; P < .00001). Comparison of 181 QT versus 176 HT autografts showed no significant differences in terms of instrumented mean side-to-side difference ( P = .75), Lachman test ( P = .41), pivot-shift test grade 0 ( P = .53), Lysholm score less than 84 ( P = .53), mean subjective IKDC score ( P = .13), donor-site pain ( P = .40), or graft failure ( P = .46). However, outcomes in favor of QT were found in terms of mean Lysholm score (mean difference between QT and HT groups, 3.81; 95% CI, 0.45-7.17; P = .03). Conclusion: QT autograft had comparable clinical and functional outcomes and graft survival rate compared with BPTB and HT autografts. However, QT autograft showed significantly less harvest site pain compared with BPTB autograft and better functional outcome scores compared with HT autograft.

Background: The biomechanical function of the anterolateral structure (ALS), which includes the anterolateral joint capsule and anterolateral ligament (ALL), remains a topic of debate. Hypothesis: The ALS contributes to knee joint stability during the Lachman test and the pivot-shift test in anterior cruciate ligament (ACL)–deficient knees. Study Design: Controlled laboratory study. Methods: Fourteen fresh-frozen hemipelvis lower limbs were used. For 7 specimens, the anterior one-third of the ALS and the residual ALS were cut intra-articularly with a radiofrequency device. Subsequently, the ACL was cut arthroscopically. For the other 7 specimens, the ACL was cut first, followed by the anterior one-third of the ALS and the residual ALS intra-articularly. During the procedures, the iliotibial band (ITB) was kept intact. At each condition, the anterior tibial translation (ATT) during the manual Lachman test and the acceleration of posterior tibial translation (APT) and the posterior tibial translation (PTT) during the manual pivot-shift test were measured quantitatively with an electromagnetic measurement system. The mean values of those parameters were compared among 6 groups (ACL intact, one-third ALS cut, all ALS cut, ACL cut, ACL/one-third ALS cut, and ACL/all ALS cut). Results: The mean ATTs during the Lachman test and the mean APTs and PTTs in the ACL-cut conditions (ACL cut, ACL/one-third ALS cut, and ACL/all ALS cut) were significantly larger than those under the ACL-intact conditions (ACL intact, one-third ALS cut, all ALS cut) ( P < .01). However, no statistically significant differences were observed among the intact, one-third ALS–cut, and all ALS–cut conditions, within the ACL-intact or ACL-cut conditions. Conclusion: Intra-articular dissection of the ALS did not increase the ATT during the Lachman test or the APT and PTT during the pivot-shift test under the intact condition of the ITB, regardless of the integrity of the ACL. When the ITB is intact, the ALS does not have a significant role in either anterior or dynamic rotatory knee stability, while the ACL does. Clinical Relevance: Recent growing interest about ALL reconstruction or ALS augmentation may not have a large role in controlling either anterior or dynamic rotatory knee instability in isolated ACL-deficient knees.

Objectives: Single-bundle, anatomic anterior cruciate ligament reconstruction (ACLR) may not fully restore rotatory knee stability, and the addition of a lateral extra-articular tenodesis (LET) has been proposed as means for reducing residual rotatory knee instability. However, the magnitude of the in vivo, time zero effects of these procedures on rotatory knee instability remain poorly defined. The pivot shift test is used to assess for rotatory knee instability; however, it is a subjective grading system with limited generalizability and ability to predict clinical outcomes. Consequently, a quantified pivot shift (QPS) test software application, PIVOT iPad, has been developed and validated to measure the magnitude of rotatory knee laxity. The objective of this study was use intraoperative QPS (iQPS) to assess for differences in residual rotatory knee instability after ACLR versus ACLR augmented with lateral extra-articular tenodesis (ACLR + LET.) Methods: During examination under anesthesia (EUA), QPS was performed on both the operative and non-operative knees prior to ACLR (Figure 1A) Three, yellow ¾ inch markers were attached to skin overlying bony landmarks: lateral epicondyle, Gerdy’s tubercle and 3 cm posterior to Gerdy’s tubercle. The PIVOT software application was used to measure lateral compartment translation (Figure 1B) ACLR were randomly augmented with a LET if the lateral compartment translation measured during QPS was greater than or equal to double the amount of lateral compartment translation measured for the unaffected knee. iQPS measurements were subsequently performed after either ACLR or ACLR + LET with sterile markers (Figure 1C) iQPS data were recorded and compared to both the preoperative QPS measurements of the affected and unaffected knees. Based upon normative QPS data established from a database of >150 previously performed ACLR at our institution, it was determined that 8 patients in each group would be required to achieve 80% power with an effect size of 1.2 mm and an alpha level of 0.05. Post-procedure iQPS data were compared to preoperative QPS measurements with paired samples t-tests. Results: iQPS measurements were performed in 20 ACLR (10 ACLR and 10 ACLR + LET). The mean age in the cohort was 17.3 years old (range: 17-24 years old.). Both ACLR and ACLR + LET resulted in significant decreases in rotatory knee instability when compared to preoperative QPS measurements (pre-ACLR: 4.7 ± 1.9 v. post-ACLR: 1.3 ± 0.70, P < 0.001; pre-ACLR +LET: 3.6 ± 1.8 v. post-ACLR + LET: 0.9 ± 0.5, P < 0.001.) When comparing isolated ACLR to ACLR + LET, no significant differences were observed in the magnitude of change in iQPS between the pre and post-intervention states (ACLR: - 3.5 ± 1.6 mm v. ACLR + LET: -1.5 ± 3.1 mm, P = N.S.) Furthermore, there were no significant differences in lateral compartment translation between the operative knees and non-operative knees (ACLR: -0.1 ± 0.9 mm v. ACLR + LET: -0.5 ± 1.0 mm, P = N.S.), suggesting that neither ACLR nor ACLR + LET led to over-constrained kinematics. Conclusion: In this randomized control study, both ACLR and ACLR + LET resulted in significant decreases in rotatory knee instability. However, there were no significant differences in time-zero, rotatory knee instability detected between isolated ACLR versus ACLR combined with LET in patients. The utility of combining a LET with ACLR remains unclear, and future research is necessary to refine the indications for LET in patients with high-grade rotatory knee instability.

Background: Several arthroscopic techniques for the treatment of avulsion tibial spine fractures have been described in the literature. Purpose: To evaluate the outcomes of the arthroscopically assisted stainless steel wiring technique in the treatment of avulsed tibial spine in adults. Study Design: Case series; Level of evidence, 4. Methods: This retrospective study involved 28 patients (28 knees), 16 to 42 years of age, with tibial spine avulsion fracture that was treated using arthroscopic reduction and cerclage wire fixation by a single surgeon between March 2015 and August 2018. The degrees of avulsion in these patients were type II (n = 12), type III (n = 10), and type IV fractures (n = 6). Clinical assessment included International Knee Documentation Committee (IKDC) objective score (which noted swelling), range of knee movement, Tegner activity scale, Lachman test, and pivot-shift test compared with the normal opposite knee. Results: The mean follow-up period was 24.1 months (range, 18-30 months). The mean IKDC score was 93.7 (range, 88.5-98.9); the IKDC score was normal in 22 patients and nearly normal in 6 patients. The Lachman test was grade 1 in 25 patients and grade 2 in 3 patients, whereas the pivot-shift test was grade 0 in 26 patients and grade 1 in 2 patients. All patients achieved their preinjury Tegner activity levels. Radiological assessment showed healing in all patients within a mean of 12 weeks after surgery. Conclusion: The outcomes of all patients were satisfactory; fixation by cerclage wiring permitted reduction of tibial spine fragment anatomically to its fracture bed, provided stable fixation in displaced tibial spine avulsion, and allowed for early rehabilitation and weightbearing because of stable fixation.

AbstractTechniques using the anteromedial portal (AMP) and accessory anteromedial portal (AAMP) are commonly used in anterior cruciate ligament (ACL) reconstruction. The aim of this study was to investigate the radiological and clinical outcomes of arthroscopic single-bundle ACL reconstruction using the AMP or AAMP technique to drill the femoral tunnel. The records of 157 patients who underwent single-bundle ACL reconstruction using the AMP or AAMP technique between 2011 and 2015 were reviewed. The femoral tunnel clock-face position and femoral tunnel and tibial tunnel anterior–posterior (AP) inclination angles were assessed on axial or AP magnetic resonance images. At last follow-up, the Lachman test and pivot-shift test were used to evaluate AP and rotational stability, respectively. The Lysholm knee scoring scale and the International Knee Documentation Committee (IKDC) form were used to evaluate clinical and functional results. No statistically significant differences were found between the groups in patient age, sex, follow-up period, or affected side distribution. The mean femoral tunnel inclination angle was 31.13 ± 8.06 degrees in the AMP group and 30.17 ± 9.02 degrees in the AAMP group (p = 0.513). The tibial tunnel inclination angle in the AMP group (16.28 ± 7.89 degrees) was not different from that in the AAMP group (13.70 ± 6.08 degrees). No significant differences were observed between the two groups in the Lachman test, pivot-shift test, Lysholm knee scoring scale, or IKDC scores. The AAMP technique was not clinically superior to the AMP technique in ACL reconstruction. This is a retrospective comparative study and its level of evidence is III.
