Hyaluronic Acid - Can it help after Arthroscopy?

Hyaluronic Acid has been shown to have limited success when used in isolation to treat osteoarthritis. It helps some but not all people, and its benefits may be short lived.

A new study has looked at the use of Hyaluronic Acid after knee arthroscopy. The results of a Weill Medical College investigation showed that patients receiving a series of three injections after their knee surgery had less pain and increased mobility on follow up at 3 and 6 months.

Points to consider:

Knee arthroscopy for osteoarthritis has been shown to be of little benefit unless mechanical symptoms of meniscal tears exist.

The study was limited by a small sample size. A much larger study is required before any benefit can be confirmed.

Having three injections after surgery is likely to slightly increase the risk of infection. Any benefit would need to be large enough to offset this increased risk.

It will be interesting to see what future research reveals.
