After a snowboarding accident I was left with a knee that I couldn't run on. I saw physios for 2 years and saw no improvement. 2 months of osteopathy(twice a week) and yoga(3 classes + 20 minutes at home on the other days per week) and I was good to go, running, snowboarding, the works. I find I still need to do some yoga every now and again(maybe once or twice a month) but apart from that it's forgotten.
