Reversal of Peroneal Tenodesis With Allograft Reconstruction of the Peroneus Brevis and Longus: Case Report and Surgical Technique.

Chronic peroneal tendinopathy and tears represent a challenging clinical situation. Traditionally, tenodesis of the torn tendon to the remaining healthy tendon has been advocated if more than half of the tendon is compromised. Allograft reconstructions have been reserved for patients with functional muscles and both peroneal tendons extensively compromised. We report a unique case of a peroneal tenodesis takedown and reconstruction of both peroneal tendons using semitendinosus allograft. A description of the surgical technique and tips are provided. Peroneal tendon function is crucial to maintain a balanced hindfoot. To the best of our knowledge, reconstruction of both peroneal tendons after a tenodesis has not been previously reported. Allograft reconstruction of the peroneal tendons arises as a feasible alternative in patients with residual pain and weakness after a failed tenodesis surgery LEVELS OF EVIDENCE: Therapeutic Level IV, case study.
