This study is being done to determine how well a needle can be placed into your knee joint with the use of an ultrasound machine for guidance and to find out if specific nerves can be reached with anesthetic or placebo to prevent the pain in the knee. We are interested if we can reach the specific nerve that will be anesthetized to prevent the pain.
