LAS VEGAS — Patients who underwent total knee arthroplasty and had a previous patella fracture had implant survival rates similar to patients who underwent total knee arthroplasty with osteoarthritis, according to research presented at the American Academy of Orthopaedic Surgeons Annual Meeting, here.
Matthew Houdek, MD, and colleagues retrospectively analyzed 122 patients (mean age: 66 years; mean follow-up: 6 years) who underwent TKA and had a previous patella fracture between 1990 and 2013. These patients were compared for implant survival with 20,474 patients with osteoarthritis (OA) who underwent TKA during the same span. Although most fractures were treated surgically, 40% of patients had fixation hardware removed prior to TKA, whereas 86% underwent patellar resurfacing. Complications and Kaplan-Meier survivorship were evaluated.
