In some cases, after a joint dislocation, trauma, or fracture, a person experiences prolonged joint pain and discomfort and goes to the hospital to have a radiograph taken, and the doctor says, “You have traumatic arthritis. Or the doctor may say, “You may have traumatic arthritis in this joint” at the time of injury. Traumatic arthritis is not new to many people, but not many people really know what it is. What is traumatic arthritis? Traumatic arthritis, as the name suggests, is a disease caused by trauma with degenerative degeneration of articular cartilage and secondary cartilage proliferation and ossification as the main pathological changes, and joint pain and activity dysfunction as the main clinical manifestations. It is more common in young adults and athletes. Traumatic arthritis mostly occurs in the joints with frequent activities or weight-bearing, such as the knee, ankle, elbow joints. Why does traumatic arthritis occur when there is only a sprain and no fracture? When a joint is sprained and the X-ray does not show a fracture; or when an intra-articular fracture is anatomically repositioned, even if the X-ray shows that the fracture is repositioned and healing well, it does not mean that the joint function will be fully restored. This is because there may be concomitant damage to cartilage, meniscus, synovium, ligaments, and fascia, which do not show up on the X-ray. Joint deformities (e.g., internal and external knee rolls, ankle tilt, tumors, etc.), angular deformity of fracture healing, frequent movement of certain joints or frequent adoption of a particular posture, heavy obesity or unilateral limb weight-bearing after amputation, etc., can cause cumulative injuries and aggravate wear and tear and destruction of joint surfaces. How to prevent or reduce traumatic arthritis? Intra-articular fractures should be anatomically repositioned to ensure smooth joint surfaces, which is why orthopedic surgeons require surgery for intra-articular fractures even though they are not heavily displaced. Appropriate immobilization is needed to allow the joint to rest and the damaged tissues to be repaired. Moderate and active functional exercise can reduce the swelling and adhesion of the joint and reduce the degeneration of cartilage. How to treat traumatic arthritis? 1, for the etiology of treatment: fracture healing joint functional activities after a long time there is pain, should be timely MRI examination. To understand the meniscus, articular cartilage or ligament damage and repair degree. For deformity healing should be corrected early. Reduce weight, adjust the type of work if necessary; 2, symptomatic treatment: oral pain medication, blood circulation and blood stasis Chinese medicine; 3, physical metallotherapy, including: direct current therapy, infrared therapy, ultrasound therapy; magnetic therapy, etc.; 4, support to assist in reducing the weight of the joints, the joint cavity injection of medication; 5, traditional Chinese medicine, acupuncture, tui-na, osteopathic therapy, traditional Chinese medicine fumigation, poultices outside the paste treatment; 6, surgical treatment: arthroscopic joint cleaning, osteotomy, orthopedic correction, arthroscopic joint cleaning, osteoclasty, surgery. Surgery: including arthroscopic arthrocentesis, osteotomy, joint fusion, joint replacement, etc.
