Background: Gluteal tendinopathy is a common cause of lateral hip pain. Percutaneous ultrasonic tenotomy (PUT) has been used successfully for the treatment of tendinopathy of the elbow, knee, and ankle, but its use in the hip has not been described.
Purpose: To evaluate the efficacy of PUT in patients who did not respond to nonsurgical management of gluteal tendinopathy.
Study design: Case series; Level of evidence, 4.
Methods: A total of 29 patients with gluteal tendinopathy (mean age, 62 years) who did not respond to nonsurgical treatment were enrolled in this prospective study and underwent ultrasound-guided PUT in an outpatient setting. Patients with a history of ipsilateral hip surgery were excluded. All patients initially underwent magnetic resonance imaging or a computed tomography arthrogram demonstrating tendinopathy and/or partial tearing of the gluteus minimus or medius tendon or both tendons. Outcomes were assessed with a visual analog scale (VAS) for pain, the Harris Hip Score evaluation, and the 12-Item Short Form Health Survey (SF-12) before the procedure and at subsequent follow-up visits or by telephone interviews at 3 weeks, 3 months, 6 months, and final follow-up (range, 18-30 months).
Results: The mean final follow-up was at 22 months postoperatively. At final follow-up, VAS scores had improved from a preprocedural mean ± SD of 5.86 ± 1.73 to 2.82 ± 2.22 (P < .01). Harris Hip Scores improved from a preprocedural mean of 60.03 ± 10.86 to 77.47 ± 14.34 (P < .01). Total SF-12 scores improved from a mean of 29.93 ± 5.39 (51% optimal) to 34.41 ± 4.88 (64% optimal) (P < .01). No complications were reported. At final follow-up, when asked whether they would have the procedure again, 15 patients replied "yes definitely," 3 replied "yes probably," 3 replied "maybe," 1 replied "likely not," and 2 replied "definitely not." There were 3 patients who eventually had hip abductor tendon repair, and their PUT procedures were considered failures.
Conclusion: PUT is an effective treatment, with good results for patients with gluteal tendinopathy.
