Randomized Controlled Trial
Clinical and Structural Evaluations of Rotator Cuff Repair With and Without Added Platelet-Rich Plasma at 5-Year Follow-up: A Prospective Randomized Study.
Platelet-rich plasma (PRP) has been studied with the objective of reducing the retear rate and improving functional outcomes after rotator cuff repair. Only one study to date has reported its midterm effect. ⋯ NCT01029574 ( ClinicalTrials.gov identifier).

Comparative Study
Allogenic Pure Platelet-Rich Plasma Therapy for Rotator Cuff Disease: A Bench and Bed Study.
Although platelet-rich plasma (PRP) is a popular option for rotator cuff disease, the underlying mechanism of PRP and its clinical indications are unclear. Further, some kinds of PRP might be detrimental to patients. Allogenic PRP prepared through a standardized process and fully characterized could eliminate variations in PRP as well as uncertainties regarding its use in each patient, which could provide clues about its mechanism of action and indications for its use. ⋯ Allogenic PRP could be a treatment option for rotator cuff disease.

Ulnar collateral ligament (UCL) reconstruction (UCLR) has shown reliable rates of return to play, with conflicting results on pitching performance after players' return. ⋯ MLB players experienced a high rate of return to play and previous level of play after UCLR. Pitching workload was maintained after returning to play. Pitching performance initially decreased the first year after returning and then improved or reverted to previous levels after the first year from UCLR.

Hip arthroscopy for femoroacetabular impingement (FAI) has been shown to improve patient outcomes, especially for returning to sport. Although previous studies often evaluated outcomes 2 years after hip arthroscopy, there has been no analysis of the progression of patient improvement over time or with respect to achieving the minimal clinically important difference (MCID). ⋯ Hip arthroscopy for FAI yields significant improvements in patient outcomes within 2 years of surgery. The majority of improvement occurs within 3 months after surgery, but certain outcomes, such as returning to sport, QoL, and pain, can continue to improve through 2 years.

Previous studies have demonstrated that hip arthroscopy is an effective treatment for symptomatic femoroacetabular impingement (FAI) in professional athletes across a variety of sports. However, the return-to-play rates and postoperative performance of elite basketball players after hip arthroscopy are currently unknown. ⋯ Elite basketball athletes who undergo hip arthroscopy for the treatment of FAI return to their presurgical levels of competition at a high rate. These athletes demonstrate no significant overall decrease in performance upon their return to play.
