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

Overview

HYPOTHESIS: 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. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
