Knee synovial fold syndrome

Brief introduction of knee synovial fold syndrome Knee joint synovial folds are repeatedly damaged or stimulated, causing a series of knee joint instability, bounce, pain and other knee joint lesions caused by synovial degeneration and hyperplasia, called knee synovial fold syndrome. This disease is similar to meniscus injury, patella softening, and the general examination is difficult to diagnose, so it is often neglected in the clinical, early targeted treatment can not be delayed, and ultimately surgical treatment. If it can be diagnosed early, acupuncture-based comprehensive treatment can achieve better results. Pain in the knee can be expressed as total knee pain, anterior knee pain, or anterior knee pain, but the pain in the upper medial space of the patellofemoral joint of the knee is mostly painful. Some patients have a sore knee joint pain. After standing for a long time, they have obvious pain in the knee joint, and the extension and flexion are limited. Some patients have an interlocking phenomenon in the knee joint (the feeling of being stuck). Most patients have a transient tibia in the knee joint with a low-pitched sound, which improves after a little activity. Jumping, going up and down the stairs, the pain is aggravated when the position is suddenly raised, and you can't stand up even after you kneel down. Long-term disease can occur in the knee muscles, ligaments disuse atrophy, knee joints are soft and weak, some patients have knee joint activity, there is friction, a small number of patients have fluid in the joint cavity. basic knowledge The proportion of illness: 0.0034% Susceptible people: no special people Mode of infection: non-infectious Complications: Arthritis

Causes of knee synovial fold syndrome

Due to violent impact on the knee joint, repeated large-scale movement of the knee joint, as well as meniscus injury, synovitis and other intra-articular lesions, stimulate the synovial folds to make it inflammatory, edema, hyperplasia, hypertrophy, adhesion and loss of elasticity, can not follow the joint Stretching and stretching, stretching and deforming, squeezing and rubbing the articular cartilage when sliding over the femoral condyle, causing acute and chronic inflammation of the synovial membrane on the joint, and even causing erosion of the cartilage surface of the femoral condyle. The swelling of the inner side wall is squeezed into the bony tissue. Cause symptoms.

Wrinkles are obviously thickened after continuous injury, and the ischemia is pale and gradually fibrotic. The synovial wall is thickened under the microscope, and the subarachnoid tissue is replaced by fibrous tissue, and few mononuclear cells invade.

Knee synovial fold prevention

1). The most important thing is to prevent joint damage. Pay attention to exercise before exercise.

2). In addition, because the synovial membrane in the long-term chronic inflammation process, it can gradually thicken, affecting the normal metabolism of synovial fluid, so it is a serous effusion, and can cause fibrosis and cause joint adhesion, affecting normal activities.

3). Properly perform the flexion and extension of the knee joint, do more static muscle strengthening exercises of the lower limb muscles, strengthen the exercise of the quadriceps, and generally do not have knee joint dysfunction.

Especially in young patients, after stopping exercise and treating with synovitis, most of them can be cured. For a longer course, the synovial folds have lost their elasticity and need to be completely removed by surgery. After the operation, the knee joint was not fixed, and the knee flexion activity was possible 5 days after the operation.

Complications of knee synovial fold syndrome Complications

It can cause progressive organic damage to the joints, and severe synovial adhesions can cause joint function loss. In severe cases, not only the knee joint activity is limited, but also the quadriceps of the quadriceps appear to have different degrees of atrophy, and more often have different degrees of arthritis.

Symptoms of knee synovial fold syndrome Common symptoms Knee joint can not fully straighten the knee joint space and pain, knee joint pain, joint swelling and pain

Pain in the knee can be expressed as total knee pain, anterior knee pain, or anterior knee pain, but the pain in the upper medial space of the patellofemoral joint of the knee is mostly painful. Some patients have a sore knee joint pain. After standing for a long time, they have obvious pain in the knee joint, and the extension and flexion are limited. Some patients have an interlocking phenomenon in the knee joint (the feeling of being stuck). Most patients have a transient tibia in the knee joint with a low-pitched sound, which improves after a little activity. Jumping, going up and down the stairs, the pain is aggravated when the position is suddenly raised, and you can't stand up even after you kneel down. Long-term disease can occur in the knee muscles, ligaments disuse atrophy, knee joints are soft and weak, some patients have knee joint activity, there is friction, a small number of patients have fluid in the joint cavity.

Examination of knee synovial fold syndrome

X-ray films showed no obvious abnormalities, and arthrography showed abnormal folds. Arthroscopy can confirm the diagnosis. However, arthroscopic examination is more serious than needle knife treatment, so there is not much inspection.

Diagnosis and differentiation of knee joint synovial fold syndrome

diagnosis

1. History of trauma, history of strain, history of illness.

2. Knee joint pain recurrent, no weight-bearing activity has a sound of sound and joint friction, muscle atrophy around the knee joint becomes loose, or thinner than the healthy side.

3. The tenderness above the humerus, the medial tenderness is more common than the lateral tenderness, and sometimes with the knee joint activity, the painful cord sliding on the femoral joint surface can be felt on the medial edge of the tibia.

4. The patient's knee joint is straight, the muscles are relaxed, and the tibia is pushed from the outside to the inside, which can induce pain or friction. Pressing the tibia gently can cause pain.

5. There is no obvious abnormality in X-ray film, and abnormality of wrinkles can be seen in arthrography. Arthroscopy can confirm the diagnosis. However, arthroscopic examination is more serious than needle knife treatment, so there is not much inspection.

Differential diagnosis

Identification of knee joint tuberculosis, knee ligament injury, and knee dislocation.
