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.

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.

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.

Quantitative muscle fat-fraction magnetic resonance (MR) imaging techniques correlate with semiquantitative Goutallier scores with failure after rotator cuff (RC) repair. ⋯ MR imaging-derived RC muscle PDFF is associated with isometric strength independent of muscle atrophy and tendon rupture in shoulders with early and advanced degenerative changes. It therefore provides complementary, clinically relevant information in tracking RC muscle composition on a quantitative level.

Previous studies have shown hip arthroscopy to be a highly effective treatment for symptomatic femoroacetabular impingement (FAI) in a wide range of athletes; however, the rate of return to play and length of career after hip arthroscopy in professional football players are unknown. ⋯ Hip arthroscopy for treatment of FAI and associated pathologic abnormalities in professional football players resulted in a high rate of return to play. The study's findings demonstrate that 87% of the arthroscopic procedures allowed professional football players to return to play, linemen were less likely to return compared with other positions, and the presence of microfracture did not significantly affect the return to play rate. These findings support hip arthroscopy as an effective procedure to treat FAI and related pathologic abnormalities in the professional football player, and this information is important for proper counseling of athletes with FAI.
