Noninvasive Management after a Traumatic Anterior Knee Dislocation in a Cruciate Retaining Total Knee Arthroplasty: A Case Report.

The reported case describes a traumatic anterior knee dislocation of a previous asymptomatic knee after a posterior cruciate-retaining primary knee arthroplasty. The described patient accidentally rolled over her knee six years after the surgical intervention. Anterior traumatic dislocation after knee arthroplasty is an uncommon event often leading to prosthetic's components revision due to its associated ligament injuries. A noninvasive approach was successfully achieved with temporary external fixation and a short period using a rigid knee brace.
