OA arthroscopy no help

There is no benefit from arthroscopic surgery for patients with osteoarthritis of the knee, according to a randomised controlled trial conducted by Canadian researchers.

Current NICE guidance states patients with severe osteoarthritis of the knee should be referred for arthroscopic surgery if lifestyle and pharmacological management is ineffective.

But the trial of 92 patients found no significant improvement in pain or joint function in patients with moderate to severe knee osteoarthritis given surgical lavage and arthroscopic debridement procedures.
