Patients with mild osteoarthritis of the elbow joint can be treated with needle knife therapy by a specialized physician, and for those with severe conditions the effect of needle knife therapy is not obvious. For patients with mild osteoarthritis of the elbow joint with joint pain and radiographic examination of joint osteophytes, needle and knife treatment can loosen the muscle fascia around the joints, so that the mechanics around the joints are balanced, which is conducive to the relief of pain. In addition to needle knife treatment can also be applied to anti-osteoporosis drugs such as anti-osteoporosis pills. For more serious osteoarthritis, with obvious narrowing of the joint space, obvious limitation of joint movement, persistent pain, progressive deformity, etc., surgical treatment is considered, and arthroplasty, osteotomy, artificial joint replacement, etc. can be chosen according to the condition, occupation, and age. Osteoarthritis of the elbow joint requires a visit to the hospital, evaluation by a specialized physician according to the specific condition, and needle knife treatment.
