This injection is used to treat the symptoms of osteoarthritis (OA).
Joints Affected by Osteoarthritis

Healthy joints contain synovial fluid. This fluid lubricates and provides nutrients to the joints. One change that happens with OA is the synovial fluid becomes thinner and less useful as a lubricant for the joint.
With viscosupplementation, hyaluronic acid, which is found in synovial fluid, is injected into the knee joint. This makes the synovial fluid act as a better lubricant. It is hoped that this will reduce pain and improve function of the joint. In some cases, getting this injection may help to postpone surgery on the knee joint.
Viscosupplementation may be a good option if you have tried other types of treatment and these have failed.
