If you or someone you know suffers from the pain of osteoarthritis (OA), it most likely has caused both pain and limited movement. It is estimated that almost 14 million Americans suffer from OA of the knee. In a normal knee, there is joint fluid that acts as a lubricant and a cushion. In OA, this fluid may have lost these features and fails to protect the knee cartilage. Injection therapy is like lubrication of the knee.
A lubricant injection is administered in three injections over a 3-week period. Lubrication and pain relief can last for up to 6 month. Some patients can feel relief immediately―in others, the full effect may take 5-9 weeks to develop.
