When performing an inside-out meniscal repair of the posterior horn of the medial meniscus, which structure is at greatest risk of iatrogenic injury if the needles are passed too far posteriorly and medially?

Explanation:
The correct option is c. During an inside-out repair of the posterior horn of the medial meniscus, the saphenous nerve and its infrapatellar branch are at the greatest risk of injury when placing posteromedial incisions or passing needles blindly. A protective retractor is essential. The popliteal vessels are central, and the common peroneal nerve is at risk during lateral meniscus repairs.
