Background: In cases of multiple ligaments or medial collateral ligament (MCL) reconstruction, restoring the native anatomy of the posterior oblique ligament (POL) to address chronic valgus instability has been attracting increased attention. Purpose: To review the current literature on postoperative outcomes, complications, and return to sports after superficial MCL-POL (sMCL-POL) reconstruction to restore medial knee integrity. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was conducted based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Two independent reviewers searched the PubMed, Scopus, Embase, and Cochrane Library databases using the terms “posterior oblique ligament,” “posteromedial corner of the knee,” and “reconstruction.” Included were studies that reported postoperative clinical and functional outcomes in patients who had undergone a combined sMCL-POL reconstruction for medial knee instability. The authors evaluated surgical technique, rehabilitation protocol, postoperative outcomes (Lysholm, International Knee Documentation Committee [IKDC], and Tegner scores and valgus stress radiograph), and return to sports and complication rates across the included studies. Results: A total of 6 studies were reviewed. The cohort consisted of 199 patients (121 men and 78 women), with a mean age of 32.7 ± 3.9 years (range, 27.4-36.6 years). The Lysholm and IKDC scores improved from pre- to postoperatively (Lysholm, from 67.2 ± 20.4 to 89.4 ± 3; IKDC, from 45.8 ± 2.1 to 84.8 ± 7.5). The Tegner score produced satisfactory results, from a preoperative mean of 3.3 ± 2.4 to 6.3 ± 0.9 postoperatively. The medial joint opening on valgus stress radiographs ranged from 7.5 ± 1.1 mm preoperatively to 3 ± 3.1 mm postoperatively. After passing activity-specific functional and clinical tests, 88% to 91.3% of the patients were reported to have returned to recreational sports within 6 to 12 months postoperatively, whereas 10% of the patients developed postoperative complications. Conclusion: Satisfactory clinical and functional outcomes, a high rate of return to recreational sports, and a low rate of postoperative complications were reported after an sMCL-POL reconstruction to restore medial knee integrity.

Introduction: The medial collateral ligament (MCL) is the most commonly injured ligament of the knee joint; however, its displacement into the medial knee compartment is rare. Traumatic posterior root of medial meniscus (PRMM) tears are commonly found in high-grade injuries involving anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) tears along with MCL tears. Diagnosis of these injuries can be made by a preoperative magnetic resonance imaging (MRI), but they can be missed at times due to severe soft-tissue swelling in the acute phase. Case Report: A 25-year-old gentleman presented with injury to the front of his left knee 5 days back. On examination, he had a Grade 3 effusion with valgus stress test and posterior drawer test being positive and medial joint line tenderness was present. A firm localized swelling was palpable on the medial joint line. MRI scan revealed a mid-substance PCL tear, ACL sprain, PRMM tear, and tibial side rupture of superficial MCL with proximally migrated wavy MCL fibers lying below the medial meniscus confirmed on arthroscopy. Medial meniscus root repair by pull through technique and PCL reconstruction with a 3-strand peroneus longus graft followed by open MCL repair with augmentation using a semitendinosus graft was performed. Postoperatively, the knee was kept in a straight knee brace for 4 weeks, followed by a hinged knee brace and appropriate physiotherapy were started. At 2 years follow-up, the patient had attained full range of knee motion with good quadriceps strength, tibial step off maintained, and negative posterior drawer test and valgus stress test. Displacement of torn MCL into the medial knee compartment is an extremely rare injury. Proximal or distal avulsion of MCL with intra-articular incarceration has been reported in isolation or associated with ACL tear. Such an injury triad as reported here has not been reported in the literature to the best of our review. Conclusion: In our case, we report a ver

Background: Little is known about the dynamic restraints of the semimembranosus muscle (SM). Purpose and Hypothesis: The goal of the present study was to elucidate the role of (1) passive and (2) active restraints to medial-side instability and to analyze (3) the corresponding tightening of the posteromedial structures by loading the SM. It was hypothesized that points 1 to 3 will significantly restrain medial knee instability. This will aid in understanding the synergistic effect of the semimembranosus corner. Study Design: Controlled laboratory study. Methods: Nine knees were tested in a 6 degrees of freedom robotic setup and an optical tracking system. External rotation (ER; 4 N·m), internal rotation (4 N·m), anteromedial rotation (4-N·m ER and 89-N anterior tibial translation), and valgus rotation (8 N·m) were applied at 0°, 30°, 60°, and 90°, with and without an SM load of 75 N. Sequential cutting of the medial collateral ligament and posterior oblique ligament was then performed. At the intact state of the knee and after each cut, the aforementioned simulated laxity tests were performed. Results: The medial collateral ligament was found to be the main passive stabilizer to ER and anteromedial rotation, resulting in 9.3° ± 6.8° ( P < .05), 8.1° ± 3.6° ( P < .05), and 7.6° ± 4.2° ( P < .05) at 30°, 60°, and 90°, respectively. Conversely, after the posterior oblique ligament was cut, internal rotation instability increased significantly at early flexion angles (9.3° ± 3.2° at 0° and 5.2° ± 1.1 at 30°). Loading the SM had an overall effect on restraining ER ( P < .001) and anteromedial rotation ( P < .001). This increased with flexion angle and sectioning of the medial structures and resulted in a pooled 2.8° ± 1.7° (not significant), 5.4° ± 2° ( P < .01), 7.5° ± 2.8° ( P < .001), and 8.3° ± 4.4° ( P < .001) at 0°, 30°, 60°, and 90° when compared with the unloaded state. Conclusion: The SM was found to be a main active restraint to ER and anteromedial rotation, especially at higher flexion angles and in absence of the main passive medial restraints. The calculated tensioning effect was small in all flexion angles for all simulated laxity tests. Clinical Relevance: A complete semimembranosus avulsion may indicate severe medial knee injury, and refixation should be considered in multiligament injury.

Background There is limited information regarding directly measured load responses of the posterior oblique and superficial medial collateral ligaments in isolated and multiple medial knee ligament injury states. Hypotheses Tensile load responses from both the superficial medial collateral ligament and the posterior oblique ligament would be measurable and reproducible, and the native load-sharing relationships between these ligaments would be altered after sectioning of medial knee structures. Study Design Descriptive laboratory study. Methods Twenty-four nonpaired, fresh-frozen adult cadaveric knees were distributed into 3 sequential sectioning sequences. Buckle transducers were applied to the posterior oblique ligament and the proximal and distal divisions of the superficial medial collateral ligament; 10 N·m valgus moments and 5 N·m internal and external rotation torques were applied at 0°, 20°, 30°, 60°, and 90° of knee flexion. Results With an applied valgus and external rotation moment, there was a significant load increase on the posterior oblique ligament compared with the intact state after sectioning all other medial knee structures. With an applied external rotation torque, there was a significant load decrease on the proximal division of the superficial medial collateral ligament from the intact state after sectioning all other medial knee structures. With an applied external rotation torque, the distal division of the superficial medial collateral ligament experienced a significant load increase from the intact state after sectioning the posterior oblique ligament and the meniscofemoral division of the deep medial collateral ligament. Conclusion This study found alterations in the native load-sharing relationships of the medial knee structures after injury. Sectioning both the primary and secondary restraints to valgus and internal/external rotation of the knee alters the intricate load-sharing relationships that exist between the medial knee structures. Clinical Significance In cases in which surgical repair or reconstruction is indicated, consideration should be placed on repairing or reconstructing all injured medial knee structures to restore the native load-sharing relationships among these medial knee structures.

Abstract Purpose To define the bony attachments of the medial ligaments relative to anatomical and radiographic bony landmarks, providing information for medial collateral ligament (MCL) surgery. Method The femoral and tibial attachments of the superficial MCL (sMCL), deep MCL (dMCL) and posterior oblique ligament (POL), plus the medial epicondyle (ME) were defined by radiopaque staples in 22 knees. These were measured radiographically and optically; the precision was calculated and data normalised to the sizes of the condyles. Femoral locations were referenced to the ME and to Blumensaat’s line and the posterior cortex. Results The femoral sMCL attachment enveloped the ME, centred 1 mm proximal to it, at 37 ± 2 mm (normalised at 53 ± 2%) posterior to the most-anterior condyle border. The femoral dMCL attachment was 6 mm (8%) distal and 5 mm (7%) posterior to the ME. The femoral POL attachment was 4 mm (5%) proximal and 11 mm (15%) posterior to the ME. The tibial sMCL attachment spread from 42 to 71 mm (81–137% of A-P plateau width) below the tibial plateau. The dMCL fanned out anterodistally to a wide tibial attachment 8 mm below the plateau and between 17 and 39 mm (33–76%) A-P. The POL attached 5 mm below the plateau, posterior to the dMCL. The 95% CI intra-observer was ± 0.6 mm, inter-observer ± 1.3 mm for digitisation. The inter-observer ICC for radiographs was 0.922. Conclusion The bone attachments of the medial knee ligaments are located in relation to knee dimensions and osseous landmarks. These data facilitate repairs and reconstructions that can restore physiological laxity and stability patterns across the arc of knee flexion.

Background: Medial collateral ligament (MCL) injuries are common after elbow trauma and in overhead throwing athletes. A hinged elbow orthosis (HEO) is often used to protect the elbow from valgus stress early after injury and during early return to play. However, there is minimal evidence regarding the efficacy of these orthoses in controlling instability and their influence on long-term clinical outcomes. Purpose: (1) To quantify the effect of an HEO on elbow stability after simulated MCL injury. (2) To determine whether arm position, forearm rotation, and muscle activation influence the effectiveness of an HEO. Study Design: Controlled laboratory study. Methods: Seven cadaveric upper extremity specimens were tested in a custom simulator that enabled elbow motion via computer-controlled actuators and motors attached to relevant tendons. Specimens were examined in 2 arm positions (dependent, valgus) and 2 forearm positions (pronation, supination) during passive and simulated active elbow flexion while unbraced and then while braced with an HEO. Testing was performed in intact elbows and repeated after simulated MCL injury. An electromagnetic tracking device measured valgus angulation as an indicator of elbow stability. Results: When the arm was dependent, the HEO increased valgus angle with the forearm in pronation (+1.0°± 0.2°, P = .003) and supination (+1.5°± 0.0°, P = .006) during active motion. It had no significant effect on elbow stability during passive motion. In the valgus position, the HEO had no effect on elbow stability during passive or active motion in pronation and supination. With the arm in the valgus position with the HEO, muscle activation reduced instability during pronation (–10.3°± 2.5°, P = .006) but not supination ( P = .61). Conclusion: In this in vitro study, this HEO did not enhance mechanical stability when the arm was in the valgus and dependent positions after MCL injury. Clinical Relevance: After MCL injury, an HEO likely does not provide mechanical elbow stability during rehabilitative exercises or when the elbow is subjected to valgus stress such as occurs during throwing.

Background: Superior labrum anterior-posterior (SLAP) lesion is a common shoulder injury, particularly in overhead athletes. While surgical management has traditionally consisted of SLAP repair, high rates of revision and complications have led to alternative techniques, such as biceps tenodesis (BT). While BT is commonly reserved for older nonoverhead athletes, indications for its use have expanded in recent years. Purpose: To determine functional outcomes and return-to-sport rates among overhead athletes after BT for SLAP tear. Study Design: Systematic review. Methods: A systematic review was performed for any articles published before July 2019. The search phrase “labral tear” was used to capture maximum results, followed by keyword inclusion of “SLAP tear” and “biceps tenodesis.” Inclusion criteria included outcome studies of BT for isolated SLAP tear in athletes participating in any overhead sports, not limited to throwing alone. Abstracts and manuscripts were independently reviewed to determine eligibility. When clearly delineated, outcome variables from multiple studies were combined. Results: After full review, 8 articles met inclusion criteria (99 athletes; mean age, 19.8-47 years), with baseball and softball players the most common among them (n = 62). Type II SLAP tear was the most common diagnosis, and 0% to 44% of athletes had a failed previous SLAP repair before undergoing BT. Only 1 study included patients with concomitant rotator cuff repair. Open subpectoral BT was most commonly used, and complication rates ranged from 0% to 14%, with wound erythema, traumatic biceps tendon rupture, brachial plexus neurapraxia, and adhesive capsulitis being reported. Combined reported postoperative functional scores were as follows: American Shoulder and Elbow Surgeons, 81.7 to 97; 12-Item Short Form Health Survey physical, 50 to 54; visual analog scale for pain, 0.8-1.5; Kerlan Jobe Orthopaedic Clinic, 66 to 79; and satisfaction, 80% to 87%. The overall return-to-sports rate for overhead athletes was 70% (60 of 86). For studies that clearly delineated outcomes based on level of play/athlete, the combined return-to-sports rate was 69% (11 of 16) for recreational overhead athletes, 80% (4 of 5) for competitive/collegiate athletes, and 60% (18 of 30) for professionals. Conclusion: BT in the overhead athlete offers encouraging functional outcomes and return-to-sports rates, particularly in the recreational athlete. It can be successfully performed as an index operation rather than SLAP repair, as well as in a younger patient population. Careful consideration should be given to elite overhead athletes, particularly pitchers, who tend to experience poorer outcomes.

Background: The medial collateral ligament (MCL) is the most frequently injured ligament of the knee, but it infrequently requires surgical treatment. Current literature on MCL reconstructions is sparse and offers mixed outcome measures. Purpose/Hypothesis: The purpose of this study was to compare the outcomes of isolated MCL reconstruction and multiligamentous MCL reconstruction. Our hypothesis was that in selective patients, MCL reconstruction would significantly improve objective and subjective patient knee performance measures, those being baseline valgus laxity, range of motion, objective and subjective International Knee Documentation Committee (IKDC) scores, Tegner score, and Lysholm knee activity scores. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and utilizing 3 computer-based databases. Studies reporting clinical outcomes of patients undergoing MCL reconstruction due to chronic instability or injury with mean follow-up of at least 2 years and levels of evidence 1 to 4 were eligible for inclusion. All relevant subject demographics and study data were statistically analyzed using 2-sample and 2-proportion z tests. Results: Ten studies involving 275 patients met our inclusion criteria. Of these patients, 46 underwent isolated MCL reconstruction while another 229 underwent reconstruction of the MCL in addition to a variety of concomitant reconstructions. Overall outcomes for all patients were significant for (1) reducing the medial opening of the knee (8.1 ± 1.3 vs 1.4 ± 1.0 mm; P < .001), (2) improving the patient’s objective IKDC score (1.2% vs 88.4%; P < .001), (3) improving the patient’s subjective IKDC score (49.8 ± 6.9 vs 82.4 ± 9.6; P < .001), and (4) improving the Lysholm knee activity score (69.3 ± 5.9 vs 90.5 ± 6.6; P < .001). No differences existed between concomitant reconstruction groupings except that postoperative Lysholm scores were better for MCL/anterior cruciate ligament reconstruction than MCL/posterior cruciate ligament reconstruction (94.3 ± 4.5 vs 84.0 ± 11.7; P < .001). Normal or nearly normal range of motion was obtained by 88% of all patients. Conclusion: The systematic review of 10 studies and 275 knees found that the reported patient outcomes after MCL reconstruction were significantly improved across all measures studied, with no significant difference in outcomes between concomitant reconstructions.
