A small amount of knee dislocations is included in the irreducible knee dislocations group. In such instance, medial femoral condyle is buttonholed through the gap formed by medial retinacular and capsular structures and this prevents reduction. In this study, we present two cases in which there were irreducible posterolateral knee dislocations resulting from a low-energy trauma. In both cases, dimple sign produced by the invagination of the medial retinacular structures and capsule and ecchymosis medially were noted. Soft tissue invaginated between the trochlea and intercondylar notch was extracted by open reduction.
少量膝关节脱位被纳入不可复位膝关节脱位组。在这种情况下，股骨内侧髁通过内侧支持带和关节囊结构形成的间隙穿出，这阻碍了复位。在本研究中，我们报告了两例因低能量创伤导致的不可复位后外侧膝关节脱位病例。在这两例病例中，均观察到内侧支持带结构和关节囊内陷产生的酒窝征以及内侧瘀斑。通过切开复位取出了滑车和髁间切迹之间内陷的软组织。
