Abstract

Osteoarthritis is a significant cause of chronic pain in the elderly population with hip osteoarthritis as one of the main causes of functional disability and joint pain in adults older than 55 years. Recently, platelet rich plasma (PRP) injections have been introduced for treatment of osteoarthritis. The aim of this systematic review is to assess its effectiveness in the management of hip osteoarthritis. We performed a search of the literature for published prospective studies that assessed the effectiveness of PRP injections in the treatment of hip osteoarthritis, with a minimum follow-up of 3 months. Primary outcome measures were WOMAC and VAS scores. Five trials were identified with 185 patients undergoing treatment with ultrasound-guided intra-articular injections of PRP, compared with patients treated with hyaluronic acid alone (n = 148) or hyaluronic acid combined with PRP (n = 31) in one study. PRP was shown to improve patient outcome scores at follow-up at 6 and 12 months; however, there was no significant difference seen between patients treated with PRP or hyaluronic acid alone. Following this systematic review, we cannot currently recommend the use of intra-articular injections of PRP for the treatment of hip OA. Given that intra-articular steroid injections are the only such injection recommended by international guidelines for the treatment of hip OA, further studies comparing PRP to steroid would be of benefit to determine the value of PRP injections in hip OA.
