Symptoms of lumbar synovitis

The lumbar spine is the area most prone to problems. It can be said to be the most vulnerable part of the human body. If you are not careful, your lumbar spine will be injured, which will damage your physical condition to a certain extent. When synovitis occurs in the lumbar spine, you will feel that your walking is hindered, or even impossible to walk normally again.

Knee synovitis has no age limit and 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, limping, high local skin temperature, swollen and tense skin, or bloody fluid after joint puncture due to impact, twisting, and excessive exercise of the knee joint during exercise.

The onset can be slow or acute, with symptoms including pain and swelling in the knee joint, increased local temperature and limited joint movement. The severity of symptoms is related to the nature of the disease and the amount of fluid effusion in the joints. When the knee is actively flexed, the pain worsens and there is a feeling of swelling. During the examination, the tenderness point was not fixed and the floating patella test was positive.

Chronic synovitis presents as knee pain and swelling that is more pronounced with increased activity. When examining the knee joint movement, friction can be felt and a thickened bursa can be palpated. Most patients have quadriceps atrophy. Floating patella test was positive.

1. In young and middle-aged people, it is mostly caused by acute trauma and chronic injury. Acute trauma includes: knee sprain, meniscus injury, collateral ligament or cruciate ligament injury, joint effusion or sometimes blood accumulation, manifested as acute traumatic synovitis of the knee.

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

3. Sometimes it may be caused by simple synovial injury of the knee joint or long-term chronic knee strain, which can cause gradual swelling and dysfunction of the knee joint, and then form chronic knee synovitis.

4. Infection, among which synovial tuberculosis infection is the most common. Generally speaking, the synovium is rich in blood vessels, has good blood circulation, and has strong resistance to bacteria. However, when infected with tuberculosis bacteria, the disease progresses slowly and its symptoms vary from time to time.

Because the synovium is distributed in joints such as the hip, knee, ankle, and shoulder, synovitis can occur in these joints. Among them, the knee joint is the joint with the most synovium, the largest articular surface and the most complex structure. Because the knee joint bears heavy loads and moves a lot, it has more chances of being injured, infected or degenerated. Therefore, knee synovitis is the most common in clinical practice.
