Sodium vitrate is more effective in improving the symptoms of arthritis in non-infectious arthritis, but not in infectious arthritis. Sodium vitrate is the main component of synovial fluid secreted by the joints, and after injection into the joints, it can play the role of anti-inflammatory, pain relief, lubrication and promotion of cartilage nutrition. It is effective in improving pain, stiffness and limitation of movement caused by osteoarthritis, rheumatoid arthritis and gouty arthritis. In the injection of sodium vitrate at the same time should pay attention to appropriate rest, with hot compresses, baking, massage and other physiotherapy, as well as follow the doctor’s instructions oral glucosamine sulfate and other cartilage protection drugs for treatment can improve the efficacy. In case of infectious arthritis caused by pus in the joint, sodium vitrate should not be injected, otherwise it will easily cause the spread of infection. Intra-articular injection of sodium vitrate should be strictly aseptic, and it is recommended that patients go to a regular hospital for treatment, and have a regular aseptic operation carried out by a specialized doctor.
