Objective data on chronic injuries of the medial collateral ligament (MCL) of the ankle are scarce. Chronic MCL injuries are frequently associated with lateral collateral ligament (LCL) injuries. For patients with chronic combined MCL and LCL injuries, the authors have performed simultaneous surgery of the 2 ligaments. ⋯ MCL insufficiency resulted from medial ankle instability and medial impingement lesions. Outcomes in the patients indicated that MCL reconstruction or resection of medial impingement lesions, performed in addition to LCL reconstruction, is effective for treating chronic combined MCL and LCL injuries of the ankle.

Ankle sprains are among the most common injuries experienced by collegiate athletes. The type of ankle sprain is rarely differentiated in epidemiological studies. This differentiation is necessary, as each ankle sprain type has a unique injury mechanism and recovery period. High ankle sprains commonly result in long recovery periods. Thus, a further examination of the epidemiology of high ankle sprains is warranted. ⋯ The enhanced understanding of the epidemiology of high ankle sprains provided in our study will aid clinicians in developing targeted injury prevention strategies to mitigate the negative consequences of these injuries.

The usefulness of arthroscopic Bankart repair for collision/contact athletes has varied in previous reports. ⋯ In male collision/contact athletes, while the overall clinical outcome was unsatisfactory, a favorable outcome was achieved in athletes without a preoperative glenoid defect and athletes with bone union. The glenoid defect decreased in size postoperatively due to remodeling of the united bone fragment, and the recurrence rate was low when the final glenoid defect size was 5% or less.

The purpose of this study was to investigate clinical outcomes and structural integrity after arthroscopic repair of anterosuperior massive rotator cuff tears (RCTs) and to compare clinical outcomes between healed and retear groups. ⋯ After arthroscopic repair of anterosuperior massive RCTs, 53% of patients exhibited retearing. The healed group had better functional outcomes than the retear group. The subscapularis retear subgroup exhibited significantly inferior outcomes compared with the intact subscapularis repair subgroup.

No previous study has examined arthritic change after meniscectomy with regard to extrusion of the medial meniscus. ⋯ The preoperative extent of intrameniscal degeneration and the preoperative patterns of meniscal tear including horizontal, horizontal flap, and complex tears were associated with preoperative extrusion of the medial meniscus. The preoperative extrusion of the medial meniscus was negatively correlated with outcomes of partial meniscectomy. The preoperative extent of meniscal extrusion can be used as a predictive factor for osteoarthritis in partial meniscectomy.
