Help! I've been diagnosed with osteoarthritis in both knees at the age of 50. Having seen the MRIs and Xrays its bone on bone. Im having problems walking, going up and down stairs and anything to do with bending the knees. Have had extensive physio and both knees have been injected with hyaluronic acid which did not help. Am on a range of pain medication which is not working. Has anyone had a total knee replacement? if so, how long were you in hospital for & what were you able to do when you left hospital? Did you receive any help at home? (from Social Services)? What sort of things were problematic? Which aids were you using to help you walk?
