PURPOSE: The objective of this study is to evaluate the clinical and immunologic effects of intra-articular doses of platelet-rich plasma (PRP) in arthroscopic hip surgery for femoroacetabular impingement. METHODS: Preoperatively, patients were randomized either to receive an intra-articular injection of PRP (group I, n = 30) or not to receive PRP (group II, n = 27) at the end of hip arthroscopic surgery. To evaluate the clinical outcome and follow-up, we used the modified Harris Hip Score (mHHS) 3, 6, and 24 months after surgery. Pain was evaluated using a visual analog scale 24 hours, 48 hours, 3 months, and 6 months after surgery. The radiologic outcome was analyzed using radiographs and magnetic resonance imaging (MRI) obtained before surgery and 6 months after surgery. Labral integration and joint effusion were evaluated with MRI at 6 months. For statistical analysis, an independent t test and the Wilcoxon rank sum test were used (P < .05 was considered statistically significant). RESULTS: The visual analog scale score 48 hours after surgery was 3.04 in group I compared with 5.28 in group II (P < .05). At the 3-month follow-up, the mHHS was 91.79 in group I versus 90.97 in group II (P = .65). At the 24-month follow-up, the mHHS was 93.41 in group I (P = .56) versus 92.32 in group II (P = .52). At the 6-month follow-up, MRI showed no effusion in 36.7% of patients in group I versus 21.1% of patients in group II (P = .013). Regarding labral integration, no statistical differences were observed between the groups (P = .76). CONCLUSIONS: In this randomized study, PRP resulted in lower postoperative pain scores at 48 hours and fewer joint effusions at 6 months. These findings suggest that PRP may have a benefit regarding postoperative inflammation; however, the long-term clinical benefit is unclear. LEVEL OF EVIDENCE: Level II, lesser-quality randomized controlled trial.
