Background:
In patients with chronic lateral epicondylitis who have failed nonoperative treatment, open or percutaneous release of the common extensor origin (CEO) without subsequent reconstruction tends to result in good clinical outcomes. However, surgery can lead to iatrogenic injuries of the lateral collateral ligamentous complex, causing posterolateral rotatory instability (PLRI).
Purpose:
To determine the clinical outcomes of lateral ulnar collateral ligament (LUCL) reconstruction using a triceps tendon graft after failed open CEO surgery.
Study Design:
Case series; Level of evidence, 4.
Methods:
A total of 103, patients underwent revision surgery at a single institution because of PLRI after failed open release of the CEO (Hohmann procedure) between January 2007 and October 2016. The primary surgery had been performed at other institutions in all cases. Of these patients, 72 were available for follow-up (49 by clinical examination, 23 by telephone interview). Standardized clinical examination; Mayo Elbow Performance Score (MEPS); 11-item version of the Disabilities of the Arm, Shoulder and Hand Score (QuickDASH); subjective elbow value (SEV); and patient satisfaction were assessed at least 2 years after LUCL reconstruction.
Results:
The mean age of patients in the study was 46.9 years (range, 21-74 years), and the mean follow-up was 2.8 years after revision surgery. The mean MEPS was 78.9, and the mean QuickDASH score reached 20.4. The mean SEV was 78.6%, and 75% of the patients rated the surgery as good to excellent. Complications were detected in 14% of the patients, and 9 needed revision surgery, primarily owing to graft failure with recurrent instability (n = 5).
Conclusion:
LUCL reconstruction in patients with PLRI after release of the CEO can restore elbow stability and achieve high patient satisfaction. However, outcome scores and revision rates in this cohort were inferior to published outcomes of primary LUCL reconstruction for treatment of noniatrogenic or traumatic PLRI.
