My head still hurts after so many years of reading about knadal's knees.
Me thinks he should go visit a competent naturopathic doctor to remedy his condition.
Modern medicine has failed this young man miserably - PRP comes to mind. It's time he considers acupuncture (not even as painful as PRP injections), some chiropractic manipulation such as vertebral subluxation and a steady treatment of magnetotherapy. Magnetotherapy-type bands can be worn over the knees, thereby strengthening his musculature in that area and since he's been wearing knee bandages for so long, shouldn't be uncomfortable.
