Involves evaluation and treatment of patients with pain and disability from arthritic joints. When non-operative measures have failed a patient, arthroplasty (joint replacement) may be their best option. In an arthroplasty procedure the degenerated, worn-out surface of a joint is removed, and replaced with an artificial joint surface. Patients very often experience excellent or complete relief of their pain and return of their function, allowing them to carry on with their lives. The joint replacement surgeons at Maine Orthopaedic Center are trained and experienced in arthroplasty, including minimally invasive techniques and partial and total joint replacement techniques in the shoulder, hip, knee, and elbow.
