Nerve block injection may ease knee arthritis pain and walking trouble

This study tests whether a numbing and anti-inflammatory injection around knee nerves can reduce pain and improve walking in people with knee arthritis. About 30 adults aged 50 and older with persistent knee pain will receive either the active injection or a placebo (salt water). Both groups will also follow an exercise program. Researchers will measure pain, walking ability, and knee movement before treatment, one hour after, and one month later.
