Description
Technical Field
The invention relates to a medical appliance, in particular to a knee osteoarthritis burden reduction adjusting brace.
Background
Degenerative osteoarthropathy, also known as osteoarthritis, degenerative arthritis, senile arthritis, hypertrophic arthritis, is a degenerative disease, which is caused by degenerative injury of articular cartilage, reactive hyperplasia of articular margin and subchondral bone, and the like due to aging, obesity, strain, trauma, congenital abnormality of joint, joint deformity and other factors. It is common to the middle-aged and the elderly, and is better at the joints with heavy load and more movement (such as cervical vertebra, lumbar vertebra, knee joint, hip joint, etc.). Excessive weight bearing or use of these joints can promote degenerative changes. The clinical manifestations are slowly developing joint pain, tenderness, stiffness, joint swelling, limited mobility and joint deformity.
The main symptom is arthralgia, usually, resting pain, which is pain after rest, and the pain is relieved after a moment of activity, but the pain is aggravated after excessive activity.
The main treatment method of the disease is to reduce the load and excessive large-amplitude movement of the joints so as to delay the progress of the disease. Obese patients should lose weight and reduce the load on the joints. When the joints of the lower limbs have pathological changes, a crutch or a walking stick can be used to reduce the burden of the joints. Physical therapy and proper exercise can keep the range of motion of joints, and splint supports, walking sticks and the like can be used as necessary, thereby being helpful for controlling acute symptoms. Anti-inflammatory analgesic drugs can alleviate or control symptoms, but should be used with caution and not taken for a long time after assessing patient risk factors. Chondroprotective agents such as glucosamine sulfate have symptomatic relief and improved function, while long-term administration can delay the structural progression of the disease.
