Abstract
Distal femur and/or tibial plateau fractures adversely affect outcomes of TKA; however it is unknown if a previous patella fracture affects outcome. We reviewed 113 patients undergoing TKA with a previous patella fracture from 1990 to 2012. Component survival was compared to 19,641 patients undergoing TKA for osteoarthritis during the same period. The 15-year implant survivals following a previous patella fracture was 86%. There was no difference in implant survival compared to patients undergoing TKA for OA (P=0.31). Knee society scores significantly improved following TKA; however patients with a fracture had complications related to knee flexion. Patients undergoing primary TKA following a patella fracture have similar overall revision free survival compared to those undergoing TKA for OA at 15-years.
