At 1 month after total knee replacement (TKR), it is common to experience pain during knee bending exercises and a burning sensation around the knee, as the tissues are still healing. Mild discomfort that settles within a couple of hours after physiotherapy is usually expected. However, the pain should gradually decrease over the next few weeks. If the burning sensation is severe, associated with increasing swelling, redness, wound discharge, fever, or if the pain is worsening instead of improving, you should be evaluated to rule out infection, nerve irritation, or implant-related issues.
