Abstract

The invention relates to a load mechanical analysis device for the knee joint. The load mechanical analysis comprises at least two acceleration sensors, at least two angular velocity sensors, at leasttwo position sensors, at least two myoelectricity sensors, a flexible wearable part, a wrist wearable part and an external intelligent terminal; the acceleration sensors, the angular velocity sensors, the myoelectricity sensors and the position sensors are respectively arranged in thighs and the calves of the human body, and the flexible wearable part can ensure the normal life of the human bodyis unaffected. By the arrangement, long-term monitoring of performance of the knee joint and prevention monitoring of deterioration of the knee joint can be achieved.

Description

technical field [0001] The invention relates to a knee joint measurement and analysis device, in particular to a knee joint load mechanics analysis device. Background technique [0002] The knee joint is the largest load-bearing joint in the human body. Knee osteoarthritis is the most common musculoskeletal disease and the main cause of disability in middle-aged and elderly people. 85% of total knee replacements are due to knee osteoarthritis. One of the common problems in total knee arthroplasty is the treatment of bone defects. Bone defects can occur in the tibia, femur, and patella, and are more common in tibial plateau bone defects. The incidence of bone defects in the distal femur is lower than that in the tibia. Distal bony defects can increase the flexion-extension gap of the knee joint, especially the flexion gap. The main causes of bone defects in primary total knee arthroplasty include tibial plateau wear, osteonecrosis, condylar hypoplasia, trauma, and inflammato...
