I went to a local chiropractor about a year ago for my back, when he was done adjusting my back he ask if any thing else was bothering me. I told him my knee had been bothering me for about 3 weeks but there was probably nothing he could do. He said let me take a look at it. So he had his assistant come out with some magnets put them on my knee,poke and prodded a little, then straightened my leg out and gave it a twist. From that moment on my knee has not bothered me. I couldn't believe it! So you might try a chiropractor
