Background technique

Knee osteoarthritis is a common clinical orthopedic disease. The disease develops to the end stage and seriously affects the quality of life of patients. Only a single compartment is involved in about 1/3 of the total number of patients, and lesions mostly involve the medial compartment. For patients with knee osteoarthritis with single compartment involvement, unicompartmental arthroplasty has gradually replaced traditional total knee arthroplasty and high tibial osteotomy due to its advantages of less trauma, faster postoperative recovery, and no damage to other structures of the knee joint During surgery and imaging examination, the doctor usually needs to assist the patient to do the knee joint varus or valgus, and it will continue until the end of the filming. For patients with severe joint pain who cannot stand, the doctor also needs to help the patient to take the weight-bearing film of the lower limbs. . For this method, not only will the doctor be injured by radiation, but it is also difficult to ensure that the angle of varus and valgus of the knee joint is consistent every time it is taken. Relying on the doctor's personal experience will inevitably affect the reproducibility and reliability of imaging data. sex.
