Stiffness and pain secondary to end-stage dysfunctional osteoarthritis of the elbow can pose a therapeutic dilemma. Although total elbow arthroplasty is successful in older patients with low functional demand, alternatives to joint replacement must be found in the younger, more active individual. Interposition arthroplasty provides a salvage option for young, high-demand patients who hope to minimize functional restrictions of the affected extremity. The procedure traditionally involves release of both collateral ligaments and the joint capsule, resulting in a higher risk for postoperative instability and complications...

The medial collateral ligament (MCL) is the most commonly injured ligament in the knee. Historically, nonsurgical management for these injuries has been favored for a majority of grade I-III sprains, particularly femoral-based. However, when coupled with other injuries such as meniscotibial ligament tears or distal Stener type avulsion tears, early surgical management for these cases is recommended. This will allow for stabilization and protection of the meniscus in addition to preventing residual valgus laxity, especially related to more severe Stener-like avulsions of the superficial MCL that can be seen with meniscotibial ligament tears...

The aim of this Technical Note is to reconstruct the medial collateral ligament complex with the superior medial collateral ligament and posterior oblique ligament as anatomically as possible. An allograft or contralateral semitendinosus autograft is used for anatomic reconstruction of the superior medial collateral ligament and posterior oblique ligament. After bony fixation, the tendon bundles are sutured to the remnants of the medial collateral ligament complex. Thus, the tubular grafts are pulled apart to form a flat shape that resembles that of the normal medial ligaments...

The medial collateral ligament serves as the primary stabilizer to valgus stress on the medial side of the knee and is the most commonly injured ligament in the knee. Medial collateral ligament reconstruction can provide improved stability and clinical outcomes for patients. Advancements in techniques, including the use of an adjustable-length-loop suspensory fixation device through a longitudinal incision, have been introduced in recent years. The purpose of this Technical Note and video is to provide a minimally invasive method for medial collateral ligament reconstruction with adjustable-loop femoral fixation and posteromedial corner plication...

BACKGROUND: Proper soft-tissue balance was essential in total knee arthroplasty (TKA). Superficial medial collateral ligament (sMCL) release has been recommended in correction of severe varus knee. However, it has concerns of overcorrection. This study aimed to analyze coronal plane laxity in sMCL-released TKA patients. METHODS: We prospectively collected data from TKA patients who were operated from January 2015 to November 2018. All patients went through the same surgical steps; however, sMCL was left intact in mild-to-moderate deformity (sMCL-intact), while it was completely released in patients with severe deformity (sMCL-released)...

Lateral patellar dislocations are the second most common type of traumatic knee injury, accounting for approximately 2-3% of cases, the most common being anterior cruciate ligament (ACL) injury. There are several well-documented anatomical risk factors predisposing to patellofemoral instability for example: patella alta, trochlear dysplasia, ligamentous laxity, and genu valgum. Co-existing medial collateral ligament injury in cases of patellar dislocations in the absence of ACL injury is uncommon and infrequently reported in the literature...

Meniscal root tears remain a common problem, with devastating biomechanical and clinical consequences. Thankfully, numerous techniques have been developed to repair the symptomatic meniscal root tear. However, rates of conversion to arthroplasty are reported to be 21% to 33% at 10 years, and persistent extrusion of the meniscus at follow-up is a known limitation of current root repair techniques. There is also growing evidence that some medial meniscal root tears may be an effect of meniscal extrusion, rather than the cause of it...

Arthroscopic access to the posterior root of the medial meniscus is often difficult in a tight medial compartment. To facilitate ease of access, partial lengthening of the medial collateral ligament (MCL) "pie-crusting" has been advocated to increase the working space of the medial compartment during arthroscopy. Purported benefits of MCL include increased visualization and decreased misdiagnosis during diagnostic arthroscopy, decreased iatrogenic chondral injuries with instrumentation, and postoperative medial compartment off-loading...

The superficial medial collateral ligament (sMCL) of the human knee joint has functionally separate anterior and posterior fiber bundles. The two bundles are alternatively loaded as the knee flexion angle changes during walking. To date, the two bundles are usually not distinguished in knee ligament simulations because there has been little information about their material properties. In this study, we conducted quasi-static tensile tests on the sMCL of matured porcine stifle joints and obtained the material properties of the anterior bundle (AB), posterior bundle (PB), and whole ligament (WL)...
