Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The difference in osteotomy thickness between the medial and lateral condyles of the distal femur (the thickness of the lateral condyle of the distal femur minus the thickness of the medial condyle); | — |
Secondary
| Measure | Time frame |
|---|---|
| Valgus angle of distal femur in coronal plane (included angle between mechanical axis of femur and anatomical axis of distal femur in coronal plane);Rotational osteotomy angle of posterior femoral condyle (included angle between femoral condylar line and posterior condylar line);Knee Society Score, KSS;Visual Analogue Scale, VAS;Size of femoral and tibial prostheses;Knee Injury and Osteoarthritis Outcome Score,KOOS;Difference in osteotomy thickness of posterior femoral condyle (osteotomy thickness of lateral femoral condyle minus osteotomy thickness of medial femoral condyle);Tibial plateau osteotomy thickness difference (medial tibial plateau osteotomy thickness minus lateral tibial plateau osteotomy thickness);Time and economic costs of manual preoperative planning and AI preoperative planning; | — |
