Purpose: The purpose of this prospective study was to evaluate the arthroscopic treatment of trochanteric bursitis in patients who have not responded to nonoperative treatment. Methods: Thirty patients were enrolled in this study to evaluate the results of arthroscopic bursectomy. Outcomes were assessed by use of a visual analog pain scale, Harris Hip Score, Short Form 36 Health Survey, and additional specific hip function questions. Patients were given the self-administered outcome questionnaires before surgery and at subsequent follow-up visits. Of the patients, 25 were available for a mean follow-up of 26.1 months (range, 13.8 to 41 months). Results: Pain scores on the visual analog scale improved from a preoperative mean of 7.2 (0, no pain; 10, worst pain) to a postoperative mean of 3.1 at final follow-up (P = .0001). Mean Harris Hip Scores improved from a mean of 51 preoperatively to 77 at follow-up (P = .0001). Improvements were also noted in the physical component summary scores of the Short Form 36. The mean physical function score improved from 33.6 preoperatively to 54 at follow-up (P = .022), and in the pain category, the mean score improved from 28.7 to 51.5 (P = .001). One postoperative complication occurred, a seroma that required repeat surgery. One patient had a failed arthroscopic bursectomy and subsequently underwent open bursectomy with resolution of symptoms. Conclusions: Arthroscopic bursectomy appears to be an effective option for recalcitrant trochanteric bursitis and is a viable alternative to open bursectomy. In this prospective study patients had good pain relief and improved function compared with their preoperative status. Improvements in a patient’s status are usually evident by 1 to 3 months after surgery and appear to be lasting. Level of Evidence: Level IV, therapeutic case series.

Study Design

After approval was obtained from our institutional review board, patients were enrolled in the study if they met the inclusion criteria of continued bursal pain and limitation of function (painful abnormal gait, pain with activities of daily living, or inability to lie on the affected side at night) after nonoperative treatment of at least 6 months’ duration. The diagnosis was made from the patient’s history, physical examination, and response to injection. A critical feature in the examination

Results

The mean length of follow-up was 26.1 months (range, 13.8 to 41 months). The visual analog scale scores improved from a preoperative mean of 7.2 to a postoperative mean of 3.1 at final follow-up (0, no pain; 10, worst pain) (P = .0001). Improvements were seen early, at the 1-month examination, and did not tend to deteriorate over time (Fig 4).

Overall, Harris Hip Scores improved from a mean of 51 preoperatively to 77 at final follow-up (P = .0001). Again, early and intermediate data showed

Discussion

When the diagnosis of trochanteric bursitis is made, most patients improve with nonoperative measures. However, when nonoperative interventions fail and the patient’s pain continues, surgical treatment is considered. Historically, this has been done successfully via an open technique.8, 9, 10 Open techniques have included bursectomies, resection and release of the IT band, or even resection of a portion of the greater trochanter.

Recently, endoscopic release of the IT band has been used to treat

Conclusions

Arthroscopic bursectomy appears to be an effective option for recalcitrant trochanteric bursitis in carefully selected patients and is a viable alternative to open bursectomy. In this prospective study patients had good pain relief and improved function compared with their preoperative status. Improvements in a patient’s status are usually evident by 1 to 3 months after surgery and appear to be lasting.
