DALLAS — At the Orthopaedic Research Society Annual Meeting, Elizabeth H. Copp discussed kinematic differences between operated and contralateral knees after unicompartmental knee arthroplasty compared with total knee arthroplasty.
“We had patients perform a chair-rise, stair-ascent and stance phase of gait while we took biplane images as well as used preoperative CT [scans] to create 3D bone models,” she said. “[UKA] knees remained in varus and had much more similar kinematics to the contralateral knee as well as the native knee.”
