• Conditions: Knee Osteoarthritis
• Interventions: Other: CT and MRI

• Registration Number: NCT05327413
• Lead Sponsor: The Affiliated Hospital of Qingdao University

Brief Summary

This study aims to compare the femoral external rotation measured on CT and MRI to that measured intraoperatively to clarify the influence of residual cartilage on posterior condyle on the preoperative planning of total knee arthroplasty.
