Lumbar Manipulation & Exercise for Knee Pain?

A new case study supports the use of lumbar spinal manipulation for anterior knee pain and quadriceps weakness. A 20-year-old man who underwent ACL reconstruction of the left knee with continued knee pain and quadriceps weakness presented for chiropractic care. He was prescribed exercises to improve his quadriceps strength and received side-lying rotational spinal manipulation. After a course of eight weekly treatments, he returned to pain-free participation in recreational sports.
