Outcome of release of the lateral extensor muscle origin for epicondylitis.

Fifty-five elbows in 53 patients affected by lateral epicondylitis for more than a year were operated on with lateral extensor release. Fifty-one patients (53 elbows) were followed-up 90 months postoperatively by two independent observers using Verhaar's score and the subjective grading scheme described by Svernlöv and Adolfsson. According to Verhaar's score 26 (49%) were excellent or good and 27 (51%) fair or poor. Women had significantly worse results than men (p<0.005). In the self-assessment there was no significant difference between men and women and 20 (40%) of the patients rated their elbows as completely recovered, 26 (47%) as improved, 7 (13%) as unchanged, and none as worse. Patients whose symptoms remained unchanged after operation were re-examined and found to have other conditions that were likely to have caused the pain. Lateral release can reduce symptoms in chronic lateral epicondylitis but some residual pain can be anticipated.
