Transient synovitis

I believe that everyone is not very clear about the term "transient", especially the term "transient synovitis". In fact, transient synovitis mainly refers to the occurrence of synovitis, which occurs frequently in the human body and has obvious causes. This is the explanation of transient synovitis, but it is still too vague. Let me give you a detailed introduction to what transient synovitis means.

Transient: refers to a clinical symptom or sign that appears once or several times in a short period of time, often with obvious inducements, such as after eating certain foods, taking certain drugs, receiving certain clinical treatments or other factors that affect the body. As the triggering factor is removed, the symptom or sign will disappear quickly.

Causes

The inner layer of the joint capsule has a very thin layer of tissue, namely the synovium. Under normal circumstances, the synovium can secrete a small amount of fluid. Its main function is to make the joint surface smoother during friction, just like adding lubricating oil to a machine. When there is some kind of irritant inside the joint, whether it is bacterial, physical or chemical, the synovium will react first, causing congestion and edema, and exuding fluid. Over time, it becomes chronic synovitis.

Clinical manifestations

The joint capsule swells, causing joint swelling.

examine

For patients with excessive or recurrent knee joint effusion, a joint effusion examination can be performed, which can reflect the nature and severity of the synovitis. Therefore, joint puncture and synovial fluid examination are of great reference value for the diagnosis and differential diagnosis of knee synovitis. [1]

diagnosis

Traumatic synovitis of the knee joint is easily misdiagnosed as "benign joint pain" and given simple symptomatic treatment, which has poor results and often leaves sequelae. Because the degree of synovial lesions and changes in joint fluid exudate are positively correlated with increased intra-articular pressure and decreased oxygen partial pressure, increasing the oxygen partial pressure in the joint cavity and reducing the intra-articular pressure can promote the absorption of inflammation and the repair of the synovium[1].

treat

The principle of treatment is to regulate and unblock the obstructed microcirculation. Recovery can be achieved as long as the obstructed microcirculation is unblocked and the output and absorption of synovial fluid secreted by the bursa are balanced. Try to reduce the frequency of water extraction and injection. Excessive water extraction and injection will stimulate the proliferation of subsynovial connective tissue fibers and aging of synovial tissue, which will significantly reduce the regeneration and repair ability of synovial tissue, making further treatment more troublesome. Do not work hard or exercise before the water accumulation is eliminated. Excessive activities will damage bones. It can be simply understood as follows: the bursa is an oil reservoir that refuels the movement of skeletal tendons in order to increase lubrication and reduce friction. If there is water accumulation, the water dilutes the synovial fluid and it cannot play a lubricating role. At this time, intense activities will cause bone friction and eventually damage the bones.
