Abstract
Incarcerated medial soft tissue after posterolateral knee dislocations has been described, but limited information pertaining to the etiology and management of cutaneous injuries from incarceration exists. We present the case of a 64-year-old man, where reduction of a posterolateral knee dislocation resulted in incarceration of medial ligamentous structures and impending skin necrosis. The patient avoided full-thickness skin necrosis, which could have complicated treatment options. Careful consideration of the soft-tissue envelope of the knee for preventing additional skin injury in the perioperative period should be considered to potentially avert additional necrosis in patients with a 'pucker' sign after knee dislocations.
