Doctors use a nerve block called an adductor canal block to numb the area around your knee before major knee surgery. This study is checking how often the numbing medicine spreads beyond the intended nerves to reach other nerves in your leg, and whether that extra spread affects how well the block works.
The adductor canal block is very effective at relieving pain after knee surgery, but doctors don't fully understand why. This research will help explain whether numbing medicine reaching additional nerves in the leg is part of what makes this technique so successful.

After you receive your adductor canal block before surgery, the research team will test the feeling and movement in your leg using simple, safe methods — like touching your skin with soft materials and asking you to move your foot. These tests will help them see which nerves were numbed by the medicine. The testing takes only a short time and happens as part of your normal surgical care.
