Comparative Study
Biomechanical analysis of the pectoralis major tendon and comparison of techniques for tendo-osseous repair.
Various described surgical techniques exist for the repair of pectoralis major ruptures at the tendo-osseous junction. It is unclear how these techniques restore the native properties of the pectoralis major tendon because its biomechanical properties have not been described. ⋯ Transosseous repair, suture anchors, and endosteal Pec Buttons appear to confer similar biomechanical integrity for pectoralis major repair. Restricting early activities to thresholds below the identified failure loads seems prudent until soft tissue healing to bone is reliably achieved.

The majority of previous literature focusing on spinal injuries in American football players is centered around catastrophic injuries; however, this may underestimate the true number of these injuries in this athletic cohort. ⋯ Spinal and axial skeleton injuries occur frequently in the NFL and can result in significant time missed from practices and games. Tackling and blocking result in the greatest number of injuries, and players performing these activities are the most likely to sustain a spinal injury. The results of this study may be used as an impetus to formulate strategies to prevent spinal injuries in American football players.

Soccer is the most common cause of sporting fracture, but little is known about patient outcome after such fractures. ⋯ Most patients sustaining a fracture while playing soccer will return to soccer at a similar level. While over one third of them will have persisting symptoms 2 years after injury, for the majority, this will not impair their soccer ability.

Review Meta Analysis
A systematic review of complications and failures associated with medial patellofemoral ligament reconstruction for recurrent patellar dislocation.
Patellofemoral instability affects activities of daily living and hinders athletic participation. Over the past 2 decades, more attention has been paid to medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar dislocations/subluxations. Numerous techniques have been reported; however, there is no consensus regarding optimal reconstruction. ⋯ Medial patellofemoral ligament reconstruction has a high rate of success for patients with patellofemoral instability; however, the complication rate of 26.1% associated with this procedure is not trivial. This study quantified complications and documented the variety of complications reported in outcomes-based literature.

Comparative Study
The positive effects of different platelet-rich plasma methods on human muscle, bone, and tendon cells.
Clinical application of platelet-rich plasma (PRP) in the realm of orthopaedic sports medicine has yielded variable results. Differences in separation methods and variability of the individual may contribute to these variable results. ⋯ The utilization of different PRP separations may result in a potentially beneficial effect on the clinically relevant target cells in vitro, but it is unclear which platelet concentration or PRP preparation may be optimal for the treatment of various cell types.
