Symptoms of synovitis

Synovitis is a common joint disease, which is more common in the knee joint. Moreover, because the knee joint has more synovium and has the most complex structure, the clinical symptoms of synovitis are mainly due to the common disease of the knee joint, which can cause congestion, edema and some vasodilation. Common serious injuries can be injuries, and the treatment of synovitis mainly focuses on exercise, health care and external application.

In daily life, preventive care is still necessary to avoid excessive activity and strain of the knee joint. If a fracture occurs, timely treatment must be sought, otherwise some symptoms of synovitis will occur. Therefore, eating less fatty meat and sweets in daily life can also be helpful.

Most cases of knee synovitis occur concurrently with the above-mentioned various knee injuries, but it can also occur alone or be secondary to knee osteoarthritis, the latter mostly occurring in the elderly. Many young and middle-aged people have a history of acute knee trauma, after which the knee joint begins to experience mild edema, pain, limited movement and lameness. Synovial reactive effusion usually appears 6-8 hours after the injury, with obvious swelling and heat in the knee joint and fear of movement. Examination revealed limited flexion and extension of the knee joint, difficulty in squatting and accompanied by pain, localized tenderness points around the joint, and a positive floating patella test. Chronic traumatic synovium may have no obvious history of trauma, and the main symptoms are weakness and limited movement of the knee joint, persistent swelling, and fear of squatting. It gets worse with increased activity and gets better with rest. Those who have been ill for a long time may feel a thickening of the knee joint capsule.

After synovial injury of the knee joint, the synovium shows congestion, edema and neutrophil infiltration. Synovial blood vessels dilate, plasma and cells extravasate, producing a large amount of exudate. At the same time, synovial cells are active and produce a large amount of mucin. The exudate contains red blood cells, white blood cells, bilirubin, fat, mucin and cellulose. In severe cases, the joint effusion is bloody. Joint swelling and limited movement. If not treated promptly, synovial hypertrophy, intra-articular adhesions and cartilage degeneration may occur in the late stage. If the injury is repeated, the synovial reaction may become chronic, manifested by infiltration of lymphocytes and plasma cells. These phenomena are all nonspecific synovial reactions.

When a synovial defect is caused by severe injury, it heals faster because synovial cells can regenerate and proliferate, and other tissues and cells can also biochemically transform into synovial cells. However, in severe hyperplastic knee arthritis, the synovial villi become edematous, hypertrophic, and thickened, forming many synovial folds of varying sizes and shapes, the subsynovial connective tissue fibers proliferate, and the synovial tissue undergoes biological aging, which significantly reduces the synovial tissue's ability to regenerate and repair. Traditional Chinese medicine believes that this disease is caused by exogenous evils, joint injuries, blocked acupoints, and fluid accumulation. Therefore, the synovitis clearing paste adopts the principle of transdermal drug delivery, which directly acts on the synovial membrane of the joints. It has the effects of promoting blood circulation and removing blood stasis, dredge meridians and collaterals, dispel wind and cold, and can effectively promote local blood circulation, improve the nutrition of surrounding tissues, promote the restoration of blocked microcirculation in the joints, and restore the dynamic balance of production and absorption of synovial fluid.

The above are the main symptoms of synovitis. After the knee joint is damaged, the synovium shows congestion, edema and neutrophil infiltration. The swelling persists and the patient dares not squat. It gets worse with more activity and gets better with rest. Avoid excessive activity and strain on the knee joint. If a fracture occurs, seek medical treatment in time, otherwise some symptoms of synovitis will occur.
