Arthroscopic treatment of post-traumatic elbow contracture

The purpose of this study was to evaluate range of motion and patient-reported outcome after complete arthroscopic release of post-traumatic elbow contracture. Fourteen consecutive patients who underwent elbow arthroscopy and capsular release were reviewed retrospectively at a minimum follow-up of 1 year. Pain and range of motion were measured. Patient outcome was assessed with the American Shoulder and Elbow Surgeons Elbow Assessment Form. Mean self-reported satisfaction on a visual analog scale was 8.4 out of 10. Only 6 patients continued to have pain, with a mean maximum pain score of 4.6 out of 10. Flexion increased from a mean of 117.5 degrees to 133 degrees, and extension improved from a mean of 35.4 degrees to 9.3 degrees. In those patients with a preoperative arc of motion less than 100 degrees (10 patients), the mean arc of motion improved from 69 degrees to 119 degrees. All patients had improved function after the procedure, with a mean self-reported functional ability score of 28.3 out of 30. There were no neurovascular complications. The improvement in range of motion and functional outcome compares favorably with open-release procedures. Combined with the potential benefits of improved joint visualization and low surgical morbidity, arthroscopic release of post-traumatic elbow contracture appears to be a reasonable alternative to open techniques.
