Summary: | Posterolateral rotatory instability (PLRI) is the most frequent form of both acute and chronic elbow instability. It is due to mechanical incompetence of the lateral collateral ligament. O’Driscoll et al described treatment of this instability by autologous reconstruction of the lateral ulnar collateral ligament. The aim of our study was to evaluate the medium and long-term clinical, functional and radiological results of patients who were surgically treated for PLRI by this technique. We hypothesized that such ligament reconstruction restores a functional joint complex and durably stabilizes the elbow and limits the long-term risk of osteoarthritis.
All patients treated for symptomatic PLRI by ligament reconstruction since January 1995 and who had a minimum follow-up of 36 months were retrospectively included.
Thirty-two patients (32 elbows) underwent clinical and radiological evaluation with a mean follow-up of 112 months (range, 36-265 months). The success rate of the procedure was 97% with one patient requiring revision reconstruction. Twenty-four patients (75%) were free from pain. Pain was significantly greater in patients with associated lesions (P = .03) and those with morbid obesity (body mass index ≥40) (P = .03). Twenty-nine (91%) patients had resumed their previous activities. Twenty-eight patients (87%) were satisfied or very satisfied. The mean Mayo Clinic score was 96/100 and the QuickDash 14.7/100. Two patients (6%) with accompanying lesions developed severe osteoarthritis.
Elbow ligament reconstruction by the technique of O’Driscoll et al effectively restores stability and limits progression to osteoarthritis in the long term. The only failure in our series was due to several technical errors. Patients who had dislocation with associated lesions or morbid obesity are at risk of poorer functional results. |
