Fig. 4From: Case report: unusual posteromedial capsular lesion with posterior lateral meniscus root tear in two patients with constitutional genu recurvatum presenting after an acute ACL injuryTrans-notch view of the posteromedial capsular lesion case 1 (A). The needle indicates the normal positioning of the posteromedial viewing portal described by Siboni et al. [24]. Once established this portal allowed to explore the extra-articular component of the tear (B) and revealed a partial tear of the semimembranosus (SM) tendon. From this perspective it is possible to appreciate the relationship between the SM and the posteromedial capsule (PMC).
