 [ Symptoms ] i may need knee replacement surgery soon i have always been quite bowed legged will the procedure straighten my legs  i am 56 years old and a former long distance runner i have been diagnosed with osteoarthritis in both knees i suffered a torn meniscus at age 43 which was removed and have not been able to run since that leg has become more bowed since i am concerned that straightening out the bowed legs will cause issues elsewhere such as the hips since i was not born with straight legs [ Disease ] i had my right knee replaced 11 months ago the surgeon will take several images of your thigh knee and leg and send scans off to some place that will design a customize replacement just for your knee mine was made of stainless steel my doctor had an actual one to show me in his office so i do not think that anything else would be changed i asked a half dozen friends the name of the surgeon who replaced their knee and chose the doctor most frequently mentioned  of course i asked if they would use himher again if needed during my in house physical therapy i met 3 patients who had both knees replaced jokingly i added that it sound like a crazy thing to do the responses were since each knew that the other one would eventually need replacing 1 for insurance reasons 2 to minimize time taken off from work hope this helps and good luck p s since my right knee was replaced it took several weeks before i could drive my car you might want to take this into consideration
