For different groups of people, the choice of prosthetic leg knee prosthesis components is not the same, roughly divided into the following groups of people:
1. Inactive patients
For patients who do not move frequently, when choosing prosthetic leg knee prosthesis components, the problem of sudden knee flexion and falls may not be considered. General prosthetic leg knee prosthesis components can satisfy this group of people.
2. Patients with long residual limbs who can control the knee joint with consciousness
For patients with long residual limbs who can control the knee joint consciously, the control function of the swing phase should be mainly considered when choosing prosthetic leg knee prosthesis components.
3. Thigh amputee patients with short residual limbs
For thigh amputee patients with short residual limbs, prosthetic leg knee prosthesis components with relatively stable support should be considered first. The specific products are mainly link-type knee joints or load-bearing self-locking knee joints.
4. Patients who engage in heavy physical labor or live in poor ground conditions
For patients who are engaged in heavy physical labor or living in poor ground conditions, more consideration should be given to freely swinging and fixed switchable knee joint prostheses in order to meet the usual sports and adapt to the ground environment.
5. Young patients with knee disarticulation
For young patients with disarranged knee joints, they prefer to use link-type knee joints with hydraulic devices with good step frequency followability.
