The Cost-Effectiveness of Platelet-Rich Plasma Compared With Hyaluronic Acid Injections for the Treatment of Knee Osteoarthritis.

Purpose: To examine the cost-effectiveness of a series (total of 3 injections) of intra-articular platelet-rich plasma (PRP) injections in comparison to that of hyaluronic acid (HA) viscosupplementation for the treatment of symptomatic knee osteoarthritis.

Methods: Outcome data regarding the use of PRP or HA injections for the treatment of symptomatic knee osteoarthritis were determined from the highest-quality data (Level I) available in the literature until 2015. Health utility values were then derived from these high-quality data.

Débridement of small partial-thickness rotator cuff tears in elite overhead throwers.

Unlabelled: Elite overhead throwing athletes with rotator cuff tears represent a unique group of patients with an ultimate goal of returning to their previous level of competition. We hypothesized débridement of small partial-thickness rotator cuff tears would return the majority of elite overhead throwing athletes to their previous level of competition. Preoperative and intraoperative findings on 82 professional pitchers who had undergone débridement of partial-thickness rotator cuff tears were evaluated using our database.
