Synovial fluid is a joint washer. His research is used in the diagnosis of various joint diseases. They mainly include infectious, aseptic or septic arthritis, osteoarthritis.
The analysis reveals which synovial fluid has a volume, as well as its transparency and color. In addition, biochemical parameters are also noted, for example, the concentration of uric acid, glucose, and total protein.
The purpose of the study may be to assess the condition during a routine examination or in case of suspected development of the disease. In addition, tests indicate the effectiveness (or lack of effect) of the treatment used.
Synovial fluid is taken during arthrocentesis. During this procedure, the skin in the area of the joint is treated with an antiseptic. For pain relief, a local anesthetic is administered. Then, using a syringe with a needle, a small amount of liquid is pumped out. After sampling, the needle is carefully removed from the joint.
Depending on the threshold of pain sensitivity, the degree of discomfort will also manifest itself. When administering an anesthetic, the patient may feel a slight sipping. During the collection of material, discomfort or a feeling of bursting may appear. Passing the needle through the joint membrane can cause short-term pain. Over the course of several days, the puncture site can be unpleasant.
At the end of the procedure, a bandage and a load are applied. To alleviate pain and reduce swelling, ice packs may be applied to the puncture site. During the first few days it is recommended to exclude the load on the joint. In the case of difficulties with limb movements, increased soreness, swelling, redness, or pus formation after arthrocentesis, a doctor should be visited.
The main complications of this study are infection and joint hemorrhage. Before the procedure, it is necessary to notify the doctor of all the available features of the condition, as well as discuss with him all the possible consequences.
When cartilage tissue of the articular surface is affected, a degenerative-dystrophic disease develops. It is called osteoarthrosis. Persons with a genetic predisposition and overweight fall into the risk group for the development of this pathology. In addition, postponed surgical interventions and joint injuries can serve as provoking factors.
In patients with osteoarthritis, synovial fluid loses its protective and lubricating properties. This occurs as a result of a gradual decrease in molecular weight and concentration of hyaluronic acid. This is one of the natural components that make up synovial fluid.
The restoration of its viscosity is carried out using a special gel. This drug contains hyaluronic acid.
The goal of the therapeutic course is to form a synovial fluid prosthesis (gel implant). Treatment involves the introduction of three injections. The interval between injections is one week.
Thus, synovial fluid is replaced. The gel implant is able to withstand shock loads of the joint.
Injection is a sterile, viscous, resilient, high molecular weight prosthesis for single use. The syringe with the drug should be stored in the refrigerator at a temperature of two to fifteen degrees. Before the injection (for twenty to forty minutes), the drug must be removed and left at room temperature.
When using the gel, exposure to other drugs is not expected.
