Figure 5. — Illustrations of the knee showing the danger zones. (A) The danger zone in repairing the lateral meniscus through the AM portal (shaded pink). The blue lines simulate a straight all-inside meniscal repair device inserted through the AM portal, and D1 and D2 indicate the distances from the lateral and medial edges of the PT to the lateral and medial borders of the peroneal nerve along the meniscocapsular junction, respectively. P1 is the distance between the medial edge of the PT and the lateral border of the popliteal artery on the posterior edge of the lateral meniscus, and PD1 is the danger zone for popliteal artery injury. (B) The danger zone in repairing the lateral meniscus through the AL portal (shaded orange). The black lines simulate a straight all-inside meniscal repair device inserted through the AL portal, and D3 and D4 indicate the distances from the lateral and medial edges of the PT to the lateral and medial borders of the peroneal nerve along the meniscocapsular junction, respectively. P2 is the distance between the medial edge of PT and the lateral border of the popliteal artery on the posterior edge of the lateral meniscus, and PD2 is the danger zone for popliteal artery injury. AL, anterolateral; AM, anteromedial; PT, popliteal tendon.
