I am going to have a total knee replacement due to having medial bone on bone on my bowlegged knees. I am concerned about my legs being straight after a lifetime of bowlegs, particularly on the new alignment of muscles and tendons that have been used to my bowleggedness. Will this cause additional discomfort and/or physical therapy to get the muscles to adapt to the new alignment after the TKR? I would appreciate hearing from anyone who has had this done. Thanks.
