[0002] Articular cartilage repair is a treatment for damage or disease of articular cartilage, aiming to restore the normal structure and function of the cartilage. Knee cartilage is prone to damage due to poor usage habits. To achieve cartilage repair, a repair framework is usually used to fix the knee joint area, reducing movement and wear, thereby aiding in the repair of knee cartilage. Patients with articular cartilage wear need to focus on joint protection and maintenance, maintaining a healthy lifestyle to reduce joint stress and help slow the progression of cartilage wear.

[0003] Currently, traditional knee braces consist of two parts, upper and lower, which are installed on the thigh and calf respectively, connected by a connector. Traditional knee braces only secure the upper and lower sides of the leg during use, leaving the joint exposed and failing to provide adequate protection. Utility Model Content

Figure 1 , Figure 2 and Figure 3 As shown, it includes a vertically set first fixing plate 1, and a second fixing plate 5 that swings left and right is hinged below the first fixing plate 1. The lower left end of the first fixing plate 1 is hinged to the upper left end of the second fixing plate 5. The two movable second fixing plates 5 follow the patient's knee joint bending and rotating, without hindering the normal movement of the knee joint.

[0020] An elastic band 3 is provided on the right side of the fixing plate. One end of the elastic band 3 is fixed to the rear side wall of the fixing plate, and the other end of the elastic band 3 is detachably connected to the front side wall of the fixing plate. The first fixing plate 1 is placed on the patient's leg. The patient holds the movable end of the elastic band 3 and wraps it around the leg, fixing the other end of the elastic band 3 to the front side wall of the first fixing plate 1. This paragraph as a whole constitutes a fixing assembly for fixing the fixing plate to the patient's leg. Of course, in the fixing assembly, the movable end of the elastic band 3 and the front side wall of the first fixing plate 1 are provided with Velcro. The hook side of the Velcro is fixed to the movable end of the elastic band 3, and the adhesive side of the Velcro is fixed to the front side wall of the first fixing plate 1. After the movable end of the elastic band 3 is wrapped around the patient's leg, it is fixed to the front side wall of the first fixing plate 1.

[0021] Support plates 6 are vertically fixed on the front and rear side walls of the second fixed plate 5. There are two support plates 6, which are fixed on the front and rear side walls of the support plate 6 respectively. The lower end of the support plate 6 is fixed on the side wall of the second fixed plate 5, and the upper end of the support plate 6 is located on the side wall of the first fixed plate 1.

[0022] The upper end of the support plate 6 is provided with a notch, and a fixing post 13 is provided in the notch. The fixing post 13 is fixed to the side wall of the first fixing plate 1. There are two fixing posts 13, which are fixed to the front and rear side walls of the first fixing plate 1 respectively, corresponding to the two notches. When the first fixing plate 1 is rotated to be parallel to the second fixing plate 5, the fixing post 13 rotates into the notch of the support plate 6, and the two fixing plates are supported by the support plate 6, thereby supporting the legs on both sides of the joint and reducing the burden on the joint.

[0023] An airbag 4 is positioned between the two fixation plates. The upper and lower ends of the airbag 4 are fixed to the corresponding fixation plates. The upper end of the airbag 4 is fixed to the lower right end of the first fixation plate 1, and the lower end is fixed to the upper right end of the second fixation plate 5. When the patient wears both fixation plates, the airbag 4 wraps around the outside of the joint to protect it. An air nozzle 12 is installed on the front of the airbag 4 to control its opening and closing. This entire section constitutes a protective component for the patient's joint. When in use, air is inflated into the airbag 4 through the air nozzle 12, causing the airbag 4 to expand and unfold. When the patient wears the fixation plates, the unfolded airbag 4 wraps around the joint, protecting it from damage and facilitating joint recovery. Alternatively, a heater can be installed at the air nozzle 12. When external gas is introduced into the airbag 4, the heater heats the gas, creating a warm environment for the joint and promoting recovery.
