Synovitis of the knee, in the elderly, is mostly secondary to osteoarthritis of the knee, mainly due to mechanical biochemical irritation from cartilage degeneration and bone proliferation, secondary to synovial edema, exudation and effusion of the knee. In young adults it is mostly due to acute trauma and chronic injury. Acute traumatic injuries include: knee sprains, meniscal injuries, lateral collateral or cruciate ligament injuries, intra-articular effusion or sometimes blood accumulation, manifesting as acute traumatic synovitis of the knee. Sometimes it can also be caused by simple knee synovial injury, such as a mild trauma, or a long-term chronic knee strain. In addition to wind, cold and dampness, the knee joint can gradually become swollen and dysfunctional, resulting in chronic synovitis of the knee joint. The swollen joint type is mainly swollen after excessive exercise, and the pain varies in severity. In the non-swollen type, joint pain predominates and is often accompanied by mild swelling. Studies have confirmed that both types are essentially the same, but differ only in the degree of synovial pathological changes. Researchers have found that after prolonged single-motion overload of the knee joint, the synovial tissue becomes congested and edematous, and the exudation of red and white blood cells and fibrin is positively correlated with the increase in intra-articular pressure and the decrease in oxygen partial pressure. Inflammation formation, thus, it is believed that the occurrence of traumatic synovitis after excessive exercise is not only related to the repetitive_strike of the joint surface and injury to the joint capsule, but also plays an important role in the development and regression of the disease process. Synovitis is a joint lesion in which the synovial membrane is stimulated to produce inflammation, resulting in the dysregulation of secretion to form a fluid, which has long affected the normal life of patients, work, and brought a lot of trouble, some patients seek medical help around, repeated attacks, pain, and even psychological overshadowing, synovitis is incurable, then synovitis can be completely cured, we believe that attention to three links: 1, timely and clear Diagnosis Synovitis symptoms are mainly joint swelling, followed by pain, dysfunction, muscle atrophy, so if you find a similar situation should be promptly consulted for a clear diagnosis, to exclude the possibility of other factors, careful examination to prevent missed diagnosis and avoid delays. Some patients are treated blindly without proper diagnosis, losing the best time for treatment. 2, timely and effective comprehensive treatment After the diagnosis of timely formal and effective treatment is very critical, synovitis early is generally mainly the acute phase, using Western medicine methods, such as: hormones, pumping, flushing, antibiotics and other treatment, can achieve satisfactory results, if the treatment is not complete, miss the best treatment period, inflammation gradually transformed into a chronic phase, repeated accumulation of fluid synovial hypertrophy, adhesions, affecting the functional problems of the joint. 3, timely functional exercise and rehabilitation after health care synovial in the treatment process, the joint to stop activities, and perhaps even braking, the purpose is to reduce fluid secretion, but this method is likely to cause loss of joint function, muscle atrophy, inducing other lesions of the joint, we advocate treatment and functional exercise at the same time, to avoid post-healing complications, with the correct functional activities, can accelerate the absorption of fluid, rehabilitation after health care It is very important to take care of the joint after recovery, because normal joints are prone to synovitis, not to mention the healing of synovitis, so it is necessary to take care of the joint after healing, to achieve the above aspects, synovitis can be completely cured.
