I was in a similar situation with PT. My therapist would try to bend my knee without progress. He said “with most people, I can tell that I can make progress but with you, I hit a hard stop”. He advised me that I was wasting time and money by continuing PT. My surgeon concurred with this. Prior to these surgeries, I had been a sprinter in the Sr. Games and an ardent weight lifter. With my pain & immobility, I quit my gym. About 6 months passed as my body aches (74 yrs. Old) increased and the future looked dark. At my wife’s persuasion, I rejoined a gym and started doing what I could, mostly upper body, and am now feeling much better overall. I look forward to my next step with the Mayo Clinic. I have to wait until April to go, since I had to change my health insurance to be covered outside my area, which means that they won’t pay for a preexisting condition until a 3 month wait period expires. Never Give Up!!!
