Introduction: As popularity of total knee arthroplasty (TKA) has increased, so have the expectations of patients with regards to function and outcomes. This study uses motion capture to analyze knee kinematics and gait cycle to characterize return to function of the operative limb compared to the non-operative limb at 3 and 6 months following primary TKA. Methods A prospective control trial performed at a tertiary referral center. 28 patients completed pre-operative motion capture analysis, with 22 patients completing the 3-month, and 19 completing the 6-month assessment. Data was collected using a VICON® Motion Capture system. Subjects performed 6 trials of walking starting from a standing position. Data was analyzed at pre-op, 3- and 6-months post-op for gait parameters (step length, width, stride length), gait cycle, and kinematic measures (joint position and range of motion [ROM]). Results No between-limb differences were observed for step or stride length. Step width remained wider at 6-months post op than prior to surgery (2.2±0.6cm, p
