Passive and weight bearing knee kinematics of 8 patients undergoing total knee arthroplasty

This database includes motion capture of the knee kinematics of 8 patients (mean ± SD: age, 70.4 ± 8.9 years; height, 161.9 ± 10 cm; weight, 78.6 ± 26.7 kg; 7 females) with end-stage knee osteoarthritis (grade III to IV on the Kellgren–Lawrence classification) that underwent total knee arthroplasty. Patients performed a standardized barefoot treadmill gait analysis using the KneeKG™ system (Emovi, Montreal, Canada) one week before and three months after TKA. Additionally, passive flexion-extension was recorded before and after total knee arthroplasty implantation using the Knee 3 computer assisted surgery system (Brainlab, Munich, Germany). The anatomical axes of the KneeKG™ and CAS systems were homogenised using two-level, multi-body kinematics optimisation. Knee kinematics computations followed the International Society of Biomechanics conventions.
