Because medial elbow stability is essential for stiff elbow release, surgical techniques have been reported for reconstructing medial elbow stability. However, medial collateral ligament (MCL) defects, caused by inevitable detachment and resection performed for complete release, make the reconstruction more challenging. To our knowledge, no study has evaluated the outcomes after using a flexor-pronator fascia patch in medial elbow reconstruction for open release of stiff elbows. We hypothesized that this technique is effective for repairing MCL defects.MethodsWe retrospectively reviewed the records of 10 patients. The MCL defects were all reconstructed with a flexor-pronator fascia patch. An external fixator was used in all patients. One patient could not be contacted and was thus excluded from the study. Outcome measures included stability, range of motion, Mayo Elbow Performance Score, ulnar nerve symptoms, power grip, and radiographic findings.ResultsThe mean follow-up period was 19.6 months; all elbows were stable by the last follow-up. One patient presented with moderate elbow instability and then regained stability 3 months after the external fixator was removed. The Mayo Elbow Performance Score improved from 58 points to 94 points, and the mean flexion arc improved from 40° to 133°. No radiographic manifestations of elbow dislocation or suture anchor looseness were observed.ConclusionA flexor-pronator fascia patch provides sufficient stability for repairing MCL defects without restricting the range of motion gained during arthrolysis.
