Description

technical field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a knee joint tissue balance measuring device and a measuring method thereof. Background technique

[0002] The knee joint is mainly composed of femur, tibia and patella. With the aging of the social population, knee joint disease has become a common disease affecting the elderly. Total knee replacement surgery is an effective method for the treatment of advanced lesions. Knee replacement refers to replacing a knee joint that has been severely damaged and cannot travel normally with a prosthesis, and restores the balance between the knee joint and the flexion gap, the balance between the medial and lateral gaps and the corresponding soft tissue during the total knee replacement process. The balance of the knee joint is a very critical step, and the measurement of the extension and flexion gap between the knee joints is a very important indicator to determine wh...
