Treatment of Recalcitrant Iliotibial Band Friction Syndrome with Open Iliotibial Band Bursectomy

Abstract

Background Iliotibial band friction syndrome (ITBFS) is an overuse injury causing lateral knee pain. There is evidence that the pathological lesion is in fact an inflamed bursa underlying the iliotibial band (ITB) rather than an inflamed ITB itself. Hypothesis Resection of the bursa underlying the ITB in ITBFS patients will relieve their pain and allow them to return to their preinjury activity level. Study Design Case series; Level of evidence, 4. Methods We describe the technique of ITB bursectomy and report a minimal 20-month follow-up of patients who had ITB bursectomies performed by a single surgeon. The patients completed a survey detailing their preoperative and postoperative symptoms and activities. Results The senior author performed 12 consecutive cases of ITB bursectomies (12 patients). One was excluded from the study (previous microfracture). The average age at surgery was 32 years (standard deviation, 5; range, 24-41). There were 7 men and 4 women. Postoperatively, patients were able to return to their preinjury Tegner activity levels, and the visual analog pain scores decreased by an average of 6 points (P < .001). Six patients were completely satisfied with the surgical outcome, 3 were mostly satisfied, 2 were somewhat satisfied, and none were dissatisfied. Nine of 11 patients said that knowing what they know now, they would have the surgery performed again for the same problem. Conclusion Iliotibial band bursectomy successfully reduces knee pain in patients with ITBFS and allows them to return to their preinjury level of activity. The great majority of patients were satisfied with the results of the procedure.
