Platelet-rich plasma (PRP) is shown to be beneficial in many pathologies.  The use of PRP in arthroscopic hip surgery demonstrates early pain relief and decreased post-operative effusion rates.  A randomized prospective study evaluated 57 patients who had arthroscopic hip surgery for femoral acetabular impingement.  30 patients received PRP injection after surgery and reported a decrease in VAS pain score at 48 hours and MRI showed less post-operative effusion rates when compared to control (Rafols et al).

A study conducted in sheep showed that PRP clot associated with microfractures filled chondral hip lesions with similar characteristics to hyaline cartilage (Milano et al).  Additionally, Mardones use of PRP clot for hip chondral lesions show excellent results.  13 patients with hip chondral lesions treated with microfracture, stem cell concentrate and PRP clot, all showed significant improvement at 3 and 6 month follow-up with Vail Hip and Modified Harris Hip Scores.  At 6 months, 4 patients had complete fill of the defect and congruity with native cartilage (Mardonnes et al).

Conclusion:  There are clinical benefits and decreased effusions with the use of PRP during and after arthroscopic hip surgery.  Hip chondral lesions are commonly found in femoral acetabular impingement during hip arthroscopy, PRP use is a promising treatment.
