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...

Embodiment Construction

[0036] Such as figure 1 As shown, the knee joint load mechanics analysis device of the present invention is characterized in that it includes an acceleration sensor, an angular velocity sensor, a position sensor, an electromyographic sensor, a flexible wearable component, a wrist wearable component, and an external intelligent terminal. The acceleration sensor, There are at least two sets of angular velocity sensors, myoelectric sensors, and position sensors, which are respectively arranged at the thigh position and the calf position of the human body. The flexible wearable parts can ensure that the normal life of the human body is not affected. The acceleration sensor, angular velocity sensor , a position sensor, and an electromyographic sensor are arranged on the flexible wearable part near the thigh and the calf, and the flexible wearable part also includes a processor, a memory and a wireless communication device inside; the wrist wearable part is provided with a touch disp...
