A new study has demonstrated that platelet-rich plasma (PRP) injections improve pain and function in patients with knee arthritis at 1-year follow-up. The study was interesting because not only did it use patient questionnaires to judge improvement in symptoms of pain and knee function, but serial MRI scans were also performed to see if the arthritis progressed. The study showed that the arthritis didn’t progress in any part of the knee at 1 year.
This is a very interesting study as contributes to the increasing body of knowledge about the usefulness of PRP in the treatment of arthritis.
We are currently using PRP injections in selected patients with knee arthritis as a joint-preservation strategy.
