PurposeThe purpose of this study was to compare clinical and radiologic outcomes biological ligament reconstruction (BLR) versus nonbiological (NBLR) for chronic injuries involving the ulnar collateral thumb's metacarpophalangeal joint.MethodsForty-two patients who underwent static BLR (n = 24) or NBLR 18) were included in retrospective analysis. Preoperative, postoperative, contralateral thumb measurements (clinical evaluation, radiographs, subjective outcome questionnaires) compared over a mean 38 months follow-up.ResultsAverage postoperative interphalangeal joint ranges motion 2° 54° 0 71°, respectively, 0° 58° NBLR. Average grip pinch strengths, relative unaffected hand, 102% 84% 103% 89%, respectively. All demonstrated stability with firm end point, thumb. The average Quick Disabilities Arm, Shoulder, Hand score among all 12 disability/symptom module, sports 17 work module. Stiffness reported four patients, no patient sustained wound-related issues other complications.ConclusionsNonbiological generates short-term comparable those BLR, potentially allowing expedited recovery rehabilitation.Type study/level evidenceTherapeutic IV. joint.
