11 weeks post TKR and everything going well. Back to gentle chair yoga, hydrotherapy swimming and walking. Sometimes long 4 or 5 miles but often shorter because of other activities. At first we would drive to a flat soft walk such as a beach, riverside or canal. Lately though I can walk on my own from the house. I felt really good . However yesterday my non surgery leg buckled under me which was really frightening and uncomfortable. I hobbled to a bench and my husband went and got the car. I can't seem to get comfortable now, slept really badly, so I am tired, but my legs are restless and just uncomfortable. I know rest and ice etc will help but I've lost so much confidence and feel quite down. I see my osteopath next week, she is really good and will sort me out. I have mild arthritis in that leg doesn't need surgery. Don't feel I can leave the house alone now
