Surgical management of lateral epicondylitis combined with ligament insufficiency.

Abstract

Lateral collateral ligament (LCL) insufficiency may occur in patients with chronic lateral epicondylitis (LE). We report on 14 consecutive patients with chronic LE and LCL insufficiency. We performed a retrospective review of 14 patients with LE and LCL insufficiency diagnosed between 2006 and 2015. The patients had undergone débridement for LE and ligament reconstruction for LCL insufficiency. The study included 9 men and 5 women with an average age of 53 years (range, 41-69 years). The mean follow-up period was 36 months (range, 24-97 months). We analyzed the pain visual analog scale score; Mayo Elbow Performance Score; Disabilities of the Arm, Shoulder and Hand score; range of motion; and posterolateral rotatory drawer test. We compared histories of steroid injection, trauma, and surgery. The pain visual analog scale score, Mayo Elbow Performance Score, and Disabilities of the Arm, Shoulder and Hand score were significantly improved postoperatively and improved in all patients. Three patients had mild instability on the stress test at final follow-up. All patients had a history of steroid injection, 2 had a history of trauma, and 3 had a history of surgery. The number of steroid injections and the number of cases receiving steroid injections more than 3 times were significantly higher in patients with LCL insufficiency. Assessment of stability is important in patients with chronic LE and risk factors such as multiple steroid injections. Simultaneous surgical treatment including open débridement and ligament reconstruction provides satisfactory pain relief and functional improvement in patients with LE and LCL insufficiency.
