Flowchart of inclusion and exclusion criteria. The inclusion criteria for this study were patients who had undergone primary TKA using the rKA method with CT-based PSI and with pre- and post-operative long-leg radiograph taken at our facility. Patients with rheumatoid arthritis, who had undergone arthroplasty using conventional alignment methods or other technology assistance, and without long-leg radiographs were excluded. Abbreviations: ACL: anterior cruciate ligament; KA: kinematic alignment; MA: mechanical alignment; PSI: patient-specific instrument; rKA: restricted kinematically alignment; TKA: total knee arthroplasty
