MEDIAL PATELLOFEMORAL LIGAMENT RECONSTRUCTION FOR NEGLECTED PATELLAR DISLOCATION POST TOTAL KNEE ARTHROPLASTY

Abstract

Patellar dislocation is considered to be an infrequent complication post total knee arthroplasty, however identifying the exact underlying pathology that led to this condition is critical, rupture medial structure could result inpatellar subluxation or permanent dislocation. We present this case report of medial patellofemoral ligament rapture reconstruction that was done to treat this unfortunate event of chronic patellar permanent dislocation following total knee arthroplasty that was neglected for four months after sustaining a twisting injury.
