Abstract
This randomized controlled study was conducted to assess the effects of platelet-rich plasma (PRP) on outcomes of total knee arthroplasty (TKA). Forty patients who underwent unilateral TKA were evaluated prospectively; 20 received intraoperative PRP and 20 served as control subjects. The results showed no significant differences in reduction of bleeding, range of motion, swelling around the knee joint, muscle power recovery, pain, Knee Society Scores, and Knee Injury and Osteoarthritis Outcome Score between the 2 groups. Additionally, no distinct clinical characteristics were found in patients who received intraoperative PRP. Therefore, we conclude that intraoperative PRP does not improve outcomes of TKA.
