A Lot of things can happen to cause a knee injury. You can tear your meniscus or your achilles tendon doing sports, a severe fall or even at work sometimes. The tear to your meniscus can cause pain by having less cushion in the knee to stop the impact of both bones hitting each other. A tear to the achilles tendon can make it very hard to even move your knee. When these tears happen you can get arthroscopy surgery to shave the muscle down so it can heal. When you have arthritis or have joint problems you would have to get a knee replacement surgery.
