Knee treatment without surgery offers lasting pain relief for 80% of arthritis patients, study finds

A non-surgical procedure that temporarily blocks extra blood vessels in the knee is offering lasting pain relief for people with knee osteoarthritis.

In a clinical study of 194 patients, 80% of them reported significant reductions in knee pain that lasted for at least a full year after receiving the treatment.

The findings highlight a potential alternative for millions of adults with chronic joint pain who have outgrown pain medications or steroid injections — but who want to avoid total knee replacement.
