Randomized Controlled Trial
Platelet-rich fibrin matrix in the management of arthroscopic repair of the rotator cuff: a prospective, randomized, double-blinded study.
Arthroscopic rotator cuff repair has a high rate of patient satisfaction. However, multiple studies have shown significant rates of anatomic failure. Biological augmentation would seem to be a reasonable technique to improve clinical outcomes and healing rates. ⋯ Platelet-rich fibrin matrix was not shown to significantly improve perioperative morbidity, clinical outcomes, or structural integrity. While longer term follow-up or different platelet-rich plasma formulations may show differences, early follow-up does not show significant improvement in perioperative morbidity, structural integrity, or clinical outcome.

Comparative Study
Femoral cortical suspension devices for soft tissue anterior cruciate ligament reconstruction: a comparative biomechanical study.
Optimization of anterior cruciate ligament (ACL) fixation is desired to improve graft healing. New soft tissue cortical suspension devices for femoral tunnel fixation should be biomechanically evaluated. ⋯ Adjustable-length loop devices may need to be retensioned after cycling the knee and fixing the tibial side to account for the increased initial displacement seen with these devices.

The Achilles tendon is one of the strongest tendons in the human body, and yet it frequently ruptures, which is a substantial clinical problem. However, the cause of ruptures remains elusive. ⋯ Earlier studies have demonstrated that specific training regimens to treat tendon injury can improve tendon composition and mechanical properties. This study supports the notion that treatment measures should aim to increase tendon collagen content and improve micromechanical quality of the tendon matrix.

Muscle injury is the most common injury type in professional soccer players. Despite this, risk factors for common lower extremity injuries remain elusive. ⋯ Intrinsic factors found to increase muscle injury rates in professional soccer were previous injury, older age, and kicking leg. Injury rates varied during different parts of the season and also depending on match location.

Intra-articular hip injuries in national hockey league players: a descriptive epidemiological study.
Intra-articular hip injuries are thought to be common in professional ice hockey; however, injury incidence and missed playing time have not been previously documented. Furthermore, it is not known if injury incidence differs between player positions. ⋯ Hip labral tears are the most frequently encountered intra-articular hip injury in the NHL player and can lead to an average of 8 man-games missed per injury. Goaltenders were not at higher risk when measuring injuries per hours played but were at significantly greater risk of an intra-articular hip injury than other on-ice players (RR, 4.7) when measured per game played.
