Vertical patella dislocation or "dorsal fin patella" is a rare but potentially debilitating orthopedic condition characterized by the displacement of the kneecap in a vertical direction. It occurs when the patella moves out of its normal position within the trochlear groove of the femur, rotating along its vertical axis resulting in the articular surface facing either medially or laterally. The mechanism of injury is primarily through axial rotation injury at the knee but could also occur secondary to a medial or lateral trauma to the patella. This dislocation can cause significant pain, immobility, and instability of the knee joint. Closed reduction to restore the patella to its proper alignment is a non-surgical technique that is uncommonly employed to treat vertical patella dislocations due to the inherent risk of osteochondral lesions. Here, we present a case of a 39-year-old male with a vertical patella dislocation after sustaining a traumatic blow to the knee during a Jiu-jitsu sparring exercise with a partner. This injury was successfully managed by a closed reduction in the emergency department.
