Explanation:
The saphenous nerve (specifically its sartorial branch) is at the greatest risk of injury during an inside-out repair of the medial meniscus. To protect it, a posteromedial incision is made, and a retractor is placed anterior to the medial head of the gastrocnemius to protect the neurovascular structures. The common peroneal nerve is at risk during lateral meniscus repairs. Reference: Campbell's Operative Orthopaedics, 14th Edition.
