Technical Field
The utility model belongs to the technical field of orthopedics nursing articles for use, relate to the brace, especially a knee joint brace for osteoarthritis patient.
Background
Osteoarthritis is the most common form of arthritis, a condition that affects millions of people worldwide. This occurs when cartilage wears away, which results in swelling, pain and difficulty moving without protective cushioning (cartilage) of the bone and bone ends. One method of treating osteoarthritis is the use of an osteoarthritis brace. Knee braces are commonly applied to the legs to treat osteoarthritis and other painful conditions of the knee. Such braces typically include an upper support, a lower support, and one or more hinge assemblies pivotally interconnecting the upper and lower supports. The upper support portion is secured to the thigh of the wearer and the lower support portion is secured to the calf of the wearer. The hinge assemblies are located on one side of the wearer's knee, and the condyle pads are typically located between each hinge assembly and the adjacent side of the knee. Knee braces are primarily designed to correct abnormal flexion inward or outward of the knee (i.e., varus and valgus correction, respectively) and to prevent the femur from contacting the tibia "bone-to-bone" within the medial and/or lateral compartment of the knee when the patient is bearing weight during walking. This act of lifting the femur, lowering the tibia, or preventing contact between the femur and tibia as the knee straightens during heel strike is commonly referred to as "unloading" of the knee joint. With knee unloading, the continual stimulation of the degenerated cartilage in the (medial or lateral) compartment of the affected knee can reduce pain and further reduce injury to the knee.
At present, the knee joint brace designed according to the functional requirements has the problem that the angle of a hinge assembly and the inward or outward abnormal bending of the brace are difficult to control in the application process, so that a knee joint brace for osteoarthritis patients needs to be designed to solve the problems of the existing knee joint brace.
