Total Knee Arthroplasty as the Primary Surgical Treatment After Knee Dislocation

Traumatic knee dislocation (KD) is a rare but serious injury, and a missed diagnosis or incorrect treatment can be limb-threatening due to a significant risk of neurovascular injury. The mechanism of injury is often high-energy trauma, but there is a rising tendency of KD after low-energy trauma in the obese patient. KD often results in multiligament injury which can be a complicated surgical task with long recovery time, especially in older patients. This report presents 4 cases where patients older than 50 years with traumatic KD have been treated with a total knee arthroplasty of revision type as an alternative to multiligament reconstruction.
