Lots of tendons and ligaments pass around the knee. When these get damaged, the knee can become painful.
Precise remedial massage will work on all of the soft tissue around the knee to help bring relief from pain and restore full range of movement.
And if you've compensated for your painful knee by adapting the way that you walk, then you may find that you've begun to ache in your other leg or hip. Remedial massage can help sort that out, too.
