Yes, red and near-infrared light therapy is generally compatible with joint replacements, including a partial knee replacement and a Birmingham hip resurfacing implant, because the device does not send electrical current through the body. However, we recommend checking with your orthopedic surgeon before using it directly over or near the replaced joint, especially if the surgery was recent or you have pain, swelling, warmth, or other complications. If approved by your doctor, start with the lowest brightness and a short session, and stop if you feel unusual discomfort.
