Degenerative Joint Disease of the Knee

This study aims to evaluate patient outcomes following robotic-assisted total knee arthroplasty using the VELYS system. Patients undergoing surgery will receive either kinematic alignment or functional alignment as determined by the operating surgeon as part of routine clinical care. Within each surgical technique group, patients will be randomly assigned to receive different implant insert types (medial stabilised or cruciate retaining) using a REDCap-based randomisation process. Patient-reported outcome measures will be collected before surgery and at follow-up time points after surgery to assess clinical outcomes.
