Now I next week I have to have a manipulation on my legt leg because I dont have good flextion or extension in my knee. Have any one every heard of any complications with having this much done on one leg in less then one year. I'm will ony be 50 years old this year and have have had my share on problems with this knee and more than anything I just wnt it to work propertly like the right one
