I am trying to walk normally but my knee buckles just as it did before surgery I am 6 weeks into my recovery and therapy had have a manipulation at 4 weeks in wasn’t bending. Therapy is brutal. Seems like the therapy team each have different technique that are painful ( soooo focused on the bend ) I am left with no other choice but to take it like a champ. Of course the following morning I am as stiff and unbendable as I was the day before so I cycle use my ball for exercises and walk five minutes or more every hour. I have osteoarthritis in this knee my pain and problems started when I was sixteen, found a benign tumor in the bone that had caused a break at nineteen now because of the size of the bone and dead tissue mass the bone had to be cut and they also placed rods in the bones so I am so looking forward to just walking without buckling.
