A 46 year old gentleman attended our clinic in Chesterfield. After being told he was too young for surgery or any injections, a gentleman from Derbyshire attended our clinic to help him get running again. For the past year he had to stop his passion of running due to severe inside knee pain. Fortunately, a single HA Ostenil injection, (Hyaluronic acid) came to the rescue and got him back to running 5km. 4 months on and he is still completing his 5km in a good time and completes his exercises to keep himself running fit.
