The docking technique for lateral ulnar collateral ligament reconstruction: surgical technique and clinical outcomes.

Abstract

Lateral ulnar collateral ligament (LUCL) reconstruction is a commonly used surgical approach for the treatment of posterolateral rotatory instability (PLRI). We hypothesized that favorable clinical results could be obtained using the docking technique. Between 1996 and 2009, the docking technique was used for surgical reconstruction of the LUCL in 8 patients with purely ligamentous posterolateral rotatory instability of the elbow. The clinical results of these patients were retrospectively reviewed. At a mean follow-up of 7.1 years (range, 5.2-9.4 years), 6 patients (75%) demonstrated complete resolution of lateral elbow instability, and 2 (25%) reported occasional instability with activities of daily living. The mean Mayo Elbow Performance Score was 87.5 (range, 75-100). Subjective assessment revealed that all patients were satisfied with their clinical outcome. LUCL reconstruction using the docking technique facilitates simple graft tensioning and excellent graft fixation. Clinical results are comparable with previously reported studies with a low complication rate.
