How Do I Treat a Sprained Knee?

Synovitis of the knee joint is a sterile type of inflammation caused by sprains of the knee joint and various intra-articular injuries. The abnormal function of the synovium can cause the joint fluid to be generated and absorbed abnormally, and the knee joint will produce fluid. The morphological changes of the synovial membrane can also invade the cartilage of the knee joint. If not treated in time, it can lead to knee osteoarthritis, and there is a great disability crisis.

Causes of knee synovitis

1. Most young people are caused by acute trauma and chronic injury. Acute trauma includes: knee sprain, meniscus injury, collateral ligament or cruciate ligament injury, fluid in the joint or sometimes blood, manifested as acute knee traumatic synovitis.

2. Synovitis in the elderly is mainly caused by mechanical biochemical stimuli due to cartilage degeneration and bone hyperplasia, secondary to synovial edema, exudation and effusion.

3. Sometimes it can be caused by simple knee synovial injury or chronic chronic knee strain, which can gradually make the knee joint swell and dysfunction, and then form chronic knee synovitis.

4. Infection, the most common of which is synovial tuberculosis infection. Generally speaking, the synovium has abundant blood vessels, good blood circulation, and strong resistance to bacteria. However, in the case of tuberculosis infection, the disease progresses slowly and its symptoms Performance is good and bad.

Clinical manifestations of knee synovitis

There is no age limit for knee synovitis and it can occur at any age. For young people, they usually have a large amount of exercise, so they are prone to swelling, pain, difficulty in movement, walking, lameness, high local skin temperature, and swollen and tense skin due to knee joints being hit, twisted, and excessive exercise during exercise Or joint puncture bleeding fluid.

Knee Synovitis

1. The knees and eyes at both sides of the patellar ligament are bulging and full, and feel palpable with hands, and even have a cystic sensation. If the joint effusion exceeds 50 ml, the floating palate test is positive.

2. The joint puncture extraction liquid is mostly yellow, clear, or pink with blood, and the bacterial culture is negative.

3. X-ray examination showed no abnormalities in the bone quality of the synovitis, or there were degenerative changes, or there were free bodies in the joints, and bone spurs at the edges of the joints.

Diagnosis of knee synovitis

Examination revealed that the knee flexion and extension were limited, squatting was difficult and accompanied by pain, and there were localized tenderness points around the joint, and the floater test was positive. Chronic traumatic synovium may not have a history of obvious trauma. It mainly manifests that the knee joint is soft and has limited movement, and the swelling persists and does not dare to squat. Aggravated when activities increased, relieved after rest. Prolonged illness can be felt to the knee capsule hypertrophy. For those who have multiple knee effusions or who have repeated effusions, joint effusions can be performed. It can reflect the nature and severity of synovitis. Therefore, joint puncture and synovial fluid examination have important reference value for the diagnosis and differential diagnosis of knee synovitis.

Knee Synovitis Treatment

1. Timely discovery and timely treatment

2. Western medicine for the treatment of knee joint synovitis mainly includes oral drugs, joint cavity

Injecting drugs, rinsing, surgery, etc.

3. Traditional Chinese medicine external therapy, massage therapy, etc.

Knee synovitis prevention

To prevent traumatic synovitis, wear knee pads and protect the knee joints during physical activities. Warm up before exercise. Usually strengthen the muscles around the knee joint strength exercises and ligament flexibility exercises.

Prevention of synovitis caused by osteoarthritis, usually pay attention to exercise, choose appropriate exercise methods according to individual physical conditions, such as walking, jogging, Tai Chi, swimming, etc., step by step. Reasonable and effective exercise can prevent bone hyperplasia, maintain joint flexibility, and reduce the occurrence of chronic injuries.
