Pros and cons of knee injection with sodium hyaluronate
Injecting sodium hyaluronate into the knee offers benefits such as relieving joint pain and promoting cartilage repair. However, potential drawbacks include local allergic reactions and increased risk of infection.
1. Benefits
Injecting sodium hyaluronate into the knee helps nourish the articular cartilage and is effective in improving knee joint effusion. It also alleviates pain caused by inflammation. Sodium hyaluronate provides lubrication, effectively reducing friction between cartilage surfaces and minimizing pain during physical activity.
2. Drawbacks
Knee injection of sodium hyaluronate may trigger local allergic reactions, causing symptoms such as pain and warmth at the injection site. In severe cases, it may lead to localized swelling. Because sodium hyaluronate nourishes the knee cartilage, the injection may create an opportunity for bacterial invasion, potentially resulting in local infection.
In addition, if an infection occurs after injecting sodium hyaluronate into the knee, treatment with oral antibiotics such as cefradine tablets or cephalothin tablets should be administered under a physician's guidance.
