Patellar tendon ruptures are rare after graft harvest for anterior cruciate ligament (ACL) reconstruction. Few reports are available in the literature. ⋯ Patellar tendon ruptures are rare after ACL graft harvest. These ruptures usually occur in either a proximal-medial and distal-lateral pattern or an entirely distal pattern, in contrast to the proximal-only tear pattern commonly observed in unharvested patellar tendons. Good objective and subjective results were achieved with repair of postoperative patellar tendon ruptures using suture anchors and Dall-Miles cable augmentation, followed by aggressive, immediate range of motion exercises.

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
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.

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.
