We assessed the outcome of arthroscopic iliopsoas release following THA from the registry of a large multi-center hip arthroscopy group.



Iliopsoas impingement and tendinopathy can cause pain after total hip arthroplasty (THA). Open release of the pathological iliopsoas tendon may alleviate pain, although there may be complications associated with the open approach. Few studies have examined the outcomes of arthroscopic release. We assessed the outcome of arthroscopic iliopsoas release following THA from the registry of a large multi-center hip arthroscopy group.


This was a multi-center retrospective review of prospectively recorded data from the MASH (multicenter arthroscopic study of the hip ) group. All consecutive patients with a THA undergoing arthroscopic iliopsoas tendon release for impingement were included. Medical records were examined for baseline demographics, intra-operative details and shortterm
post-operative outcomes including complications. Clinical outcomes were obtained via telephone including the Harris Hip Score (HHS), visual analog scale (VAS) for pain and subjective hip flexion strength (out of 10). Mean follow-up was 27 months (range, 11-62).


There were 25 patients: 12 (48%) male and 13 (52%) female with a mean age of 57.5 years (30 to 83) and body mass index of 28.1 kg/m2 (18.8-39.7). The mean time between THA and iliopsoas release was 28.6 months (6 to 60). Twenty-three (92%) of patients had a steroid injection in to the iliopsoas region: 12(48%) had a transcapsular and 13(52%) had a
distal iliopsoas release from the lesser tuberosity. Concomitant procedures were performed in 9(36%) patients: 4(16%) synovectomy, 3(12%) debridement, 1(4%) removal of loose body and 1(4%) osteophytectomy. There were no complications, although 3(12%) had persistent pain. All patients were discharged on the same day of surgery. There were
no short-term complications or further surgeries. Of the 18 patients available for follow-up, the mean Harris Hip Score was 54.1 (29.7-93.5) pre-operatively and 73.3 (40.7-100) post-operatively (p=0.02). The mean VAS pain score was 2.8 (0-8) with 14 (61.1%) satisfied or very satisfied, 3(16.7%) neutral, and 4 (22.2%) dissatisfied or very dissatisfied with the
outcome. The mean hip strength was 6.8 (0-10) and 10 (55.5%) patients stated they would have the procedure again.

Discussion And Conclusion

Arthroscopic iliopsoas tendon release in THA patients with impingement is overall a successful outpatient procedure with minimal morbidity and no complications. It leads to a significant improvement in functional outcomes although some patients have persistent pain with dissatisfaction. It is a valuable option for managing
painful THA and when diagnosed appropriately may avoid unnecessary revision procedures.
