I had my metal removed 2 years after my tfp. My accident is comming up to 3 years. All I can say it removal for me has resulted in the knee feeling week and it clicks constantly. I had an x-ray taken before the metalwork was removed that showed arthritis was an issue -poor alignment of the bone during initial surgery has not help either! I am 67yrs. My knee is stiff all the time just as it was before metal removal. I should add I go to the gym most days, do aqua aerobics twice a week and have a personal trainer session weekly. I have been told I will need a knee replacement, and that they are never as sucessfull after tfp damage.
