Randomized Controlled Trial Comparative Study
A comparative study of meniscectomy and nonoperative treatment for degenerative horizontal tears of the medial meniscus.
It is still debated whether a degenerative horizontal tear of the medial meniscus should be treated with surgery. ⋯ There were no significant differences between arthroscopic meniscectomy and nonoperative management with strengthening exercises in terms of relief in knee pain, improved knee function, or increased satisfaction in patients after 2 years of follow-up.

There are conflicting reports regarding the association between isokinetic concentric quadriceps and hamstring strength deficits and ratios and risk for hamstring injuries in athletes. ⋯ Isokinetic strength data collected from collegiate players at the NFL Scouting Combine were not useful for predicting risk of hamstring injury in subsequent professional NFL competition. These data call into question commonly accepted assumptions about risk factors for hamstring injury, at least for elite collegiate American football players, when the temporal relationship between Cybex testing and actual injury is several months.

Acromioclavicular (AC) joint separation is a common injury, usually affecting young adults. Controversy exists regarding whether to excise the distal clavicle when surgical intervention is required. ⋯ The study suggests that excision of the distal clavicle in this procedure is not associated with increased anterior-posterior or superior-inferior instability in this model.

Sex-specific outcomes have been reported in anterior cruciate ligament reconstruction as well as in osteoarthrosis progression, but there are currently no related published data on autologous chondrocyte implantation (ACI). The present prospective study was performed to investigate sex-dependent differences in the results after ACI. ⋯ Autologous chondrocyte implantation is a promising treatment option for full-thickness cartilage defects of male and female knee joints. Female patients with patellar defects have worse prognostic factors.

Tibial eminence fractures occur most commonly in skeletally immature children. Several techniques using physeal-sparing fracture fixation have been described, but their structural properties have not been evaluated. ⋯ Suture anchors provide inconsistent fixation for tibial eminence fractures.
