Problems solved by technology

[0003] However, the existing devices for monitoring the knee joint are not wearable, they are all used in the recovery stage of the disease, and cannot be effectively prevented, and cannot be monitored for a long time; at the same time, during the monitoring process of the knee joint, for monitoring There are defects in the selection of parameters and the weight assignment of parameters, and the overcoming of these difficulties will help to effectively carry out long-term and feasible monitoring of the knee joint without affecting the normal life of the human body

Abstract

The invention relates to a knee joint load mechanics analysis device, which includes an acceleration sensor, an angular velocity sensor, a position sensor, an electromyography sensor, a flexible wearable part, a wrist wearable part, and an external intelligent terminal. There are at least two sets of sensors and position sensors respectively, 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 will not be affected. Through the device of the present invention, long-term monitoring of knee joint performance and prevention monitoring of knee joint deterioration can be realized.

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...
