Common Peroneal Nerve Injury Due to an All-Inside Repair of the Posterior Horn of Lateral Meniscus

Abstract

Case: An 18-year-old man sustained a peroneal nerve (PN) injury during an all-inside repair of the posterior horn of the lateral meniscus from the medial portal. Although he could dorsiflex his ankle actively after emergence from general anesthesia, he had a foot drop on the day after surgery. Exploration of the PN at 5 months postoperatively revealed that the nerve was entrapped by the suture. Fifteen months after a nerve repair using a sural nerve graft, he recovered from the foot drop. Conclusion: This case report highlights the risk of PN injury during an all-inside repair of the posterior horn of the lateral meniscus.
