Use of Platelet-Rich Plasma for the Treatment of Acetabular Labral Tear of the Hip

Abstract

Objective This study aims to assess whether ultrasound-guided injection of platelet-rich plasma can safely and effectively treat symptoms associated with acetabular hip labral tears. Design Institutional review board approval was gained for a prospective study of eight patients (N = 8), who have previously failed conservative management, to receive ultrasound-guided injection of platelet-rich plasma at the site of hip labrum tear. We assessed pain reduction and functional ability at baseline and then 2, 6, and 8 wks after injection, using the visual analog scale and Harris Hip Score, respectively. Results Statistically significant differences in Harris Hip Score were seen 2 wks (86.5 ± 10.8, P < 0.01), 6 wks (88.0 ± 10.7) P < 0.01), and 8 wks (92.1 ± 11.6, P < 0.01) after injection as compared with baseline (76.0 ± 13.4). Corresponding improvements were seen in visual analog scale 2 wks (1.0, P < 0.01 at rest, 2.5, P < 0.01 with activity), 6 (0.9, P < 0.01 at rest, 2.3, P < 0.01 with activity), and 8 wks (0.5, P < 0.01 at rest, 1.3, P < 0.01 with activity) compared with baseline (3.8 at rest, 5.4 with activity). Conclusions Ultrasound-guided injection of platelet-rich plasma holds promise as an emerging, minimally invasive technique toward symptom relief, reducing pain, and improving function in patients with hip labral tears.

Hip Pain in an Athlete

“…If symptoms remain, a magnetic resonance arthrogram should be pursued. Image-guided IA injection with CSI and anesthetic can provide pain relief, with PRP as an emerging option (28). Lack of symptom improvement or evidence of acetabular injury should prompt surgical referral.…”
