Hello,

i am 35 years old. I have had knee problems since I was a child. Back in february 06 I fell on my right knee while roller blading and had 13 stiches. The cut healed and there are no torn ligaments or tendons, but my doctor only did x-rays of my knee. He said my knee caps pull to the outer sides. This has caused my knee to grind down from over use and wear. Now I can barley handle the pain I am in. My knee comes out of place now. This has happened three different times now. Twice before my rollerblading accident ond once since then. I have been doing some therapy to try strengthening my thigh muscles to try pulling my knee cap back where it should be, but this has only made it hurt worse. My main question is: do I need a knee replacement?

Thank you,
