Clinical Assessment after Periprosthetic Distal Femur Fracture Repair with Weight-Bearing CT

IPeriprosthetic distal femur fractures (PDFFs) following total knee arthroplasty (TKA) pose a growing challenge due to rising TKA rates and aging populations. This thesis examines the efficacy of open reduction and internal fixation (ORIF) with locking plates in 16 patients at Western University's London Health Sciences Centre, Canada. It utilizes Su and Rorabeck-Taylor classification systems and weight-bearing computed tomography (WBCT) to evaluate outcomes. All patients achieved radiographic union at one year without complications, yet patient-reported outcomes (KOOS Pain: 62.1, ADL: 47.9, KSS: 37.1, UCLA: 3.7) revealed moderate functional recovery with persistent limitations, showing no correlation with fracture type or screw placement. WBCT enhanced stability assessment. While ORIF ensures bone healing, the findings highlight the need for improved rehabilitation strategies. This study informs PDFF management, significant given Canada's projected $13 billion TKA burden by 2030.
