The thigh fixing belt 2 is used for fixing the thigh of a human body, the calf fixing belt 3 is used for fixing the calf of a human body, and the brace framework 1 supports the thigh fixing belt 2 and the calf fixing belt 3. Preferably, the brace framework 1 is made of light aluminum alloy material. The brace framework 1 includes brace framework I 11 and brace framework II 12. The brace framework I 11 is symmetrically arranged on the inner side and the outer side of the thigh fixing belt 2, the brace framework II 12 is symmetrically arranged on the inner side and the outer side of the calf fixing belt 3, and the brace framework I 11 and the brace framework II 12 on the same side are hinged, so that the brace is stably fixed on the leg of a human body for support, while not hindering the normal movement of the leg of a human body. A first pressure assembly with adjustable pressure is arranged between the two brace framework I 11, and a second pressure assembly with adjustable pressure is arranged between the two brace framework II 12. The first pressure assembly and the second pressure assembly with adjustable pressure respectively act on the upper part of the knee joint and the lower part of the knee joint, and provide appropriate lateral pressure to the knee joint according to the actual situation of a patient, so as to realize the mechanical correction of the knee joint and the balance reconstruction of the knee joint.

[0030] On the basis of the above-mentioned embodiments, as a preferred embodiment, the same side brace framework Ⅰ 11 and the brace framework Ⅱ 12 are connected by the adjusting chuck 4, and the two adjusting chucks 4 correspond to the inner and outer sides of the knee joint respectively. The adjusting chuck 4 is used to limit the movement of the knee joint to the inner and outer sides and to retain the flexion function of the knee joint.

[0031] On the basis of the above-mentioned embodiments, as a preferred embodiment, the adjusting chuck 4 is a digital adjusting chuck, the fixed disc part of the digital adjusting chuck is fixedly connected with the brace framework Ⅰ 11, and the rotating disc part of the digital adjusting chuck is fixedly connected with the brace framework Ⅱ 12. The digital adjusting chuck can adjust the range of motion of the knee joint according to the progress of the rehabilitation plan, so that the brace can play the roles of stabilization and fixation, support and protection, prevention of deformity, and load bearing after being worn.

[0032] Specifically, when the digital adjusting chuck is 0 degree, the brace framework 1 is in a completely straightened state, the digital adjusting chuck can adjust the brace to be 0-90 degrees in extension and 0-120 degrees in flexion, which meets the requirements of the dynamic and static force structure of the knee joint. It can provide an effective range of motion for normal joints and muscles, while enhancing the stability of the local area, and also enables the knee joint to move within the protection range of the brace.

Specifically, the main components of the BOA knob are: a base, a rotating wheel, and a knob cover 106. The method of use is "press, twist, pull, and drag". When pressed down, the knob cover 106 is twisted to tighten; when loosening is needed, the knob cover 106 is pulled out, and cable I 103 or cable II 104 is pulled to loosen. That is, the ratchet and one-way gear are used. "Press" means pressing the knob cover 106 to engage the internal ratchet and gear; "Twist" means twisting the knob cover 106 to drive the internal rotating wheel to tighten cable I 103; "Pull" means pulling out the knob cover 106 to disengage it from the internal gear and ratchet; "Pull" means that after the internal ratchet and gear disengage, the rotating wheel is in an unrestrained state, the rotating wheel rotates in the opposite direction, and cable I 103 is released.
