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