There are 2 types of hazards associated with intra-articular sodium vitamate injections: 1. Sodium vitamate injections into the joint can treat osteoarthritis of the joint under normal circumstances. If the drug is not injected within the joint cavity when sodium vitrate is injected, but within the synovial membrane, it will lead to particularly severe pain in the knee joint and temporarily lead to joint dysfunction.2. The hazards of sodium vitrate injection also include infection in the knee joint. If the lack of awareness of aseptic operation during the process of sodium vitrate injection leads to infection within the knee joint, the consequences will be very serious and will cause tissue infection, and even need to do surgery to treat completely.
