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.

Randomized Controlled Trial Multicenter Study Comparative Study
Calcific tendinitis of the rotator cuff: a randomized controlled trial of ultrasound-guided needling and lavage versus subacromial corticosteroids.
Calcific tendinitis of the rotator cuff (RCCT) is frequently diagnosed in patients with shoulder pain, but there is no consensus on its treatment. ⋯ On average, there was improvement at 1-year follow-up in both treatment groups, but clinical and radiographic results were significantly better in the barbotage group.

There have been no previous studies showing clinical outcomes according to treatment options of posterior cruciate ligament (PCL) injury with mild grade 2 or less posterior translation (<7 mm) combined with posterolateral rotatory instability. ⋯ Simultaneous reconstruction of the PCL and PLC is recommended when addressing PCL injuries with mild grade 2 or less posterior translation combined with posterolateral rotary instability.

Comparative Study
Biomechanical comparison of anatomic single- and double-bundle anterior cruciate ligament reconstructions: an in vitro study.
Arthroscopic identification of the anteromedial (AM) and posterolateral (PL) bundle locations of the anterior cruciate ligament (ACL) has facilitated an improved quantitative description of ACL anatomy. Few studies have directly compared the biomechanical laxity of anatomic single-bundle (SB) versus anatomic double-bundle (DB) ACL reconstruction techniques based on precise anatomic descriptions. ⋯ Although significant differences between reconstructions were observed for internal rotation, the small magnitude of these differences (<3°) may not have clinical significance.
