Patient-ready. 90 Day warranty. The Chattanooga OptiFlex 3 Knee CPMis designed to provide anatomical motion for CPM knee patients from pediatric to adult. This is a brand new item and comes with a one year warranty. Continuous Passive Motion is a postoperative procedure designed to aid in patient recovery after joint surgery. This unit is typicallyused postoperatively for total knee replacement and Anterior Cruciate Ligament (ACL) repairs. After extensive joint surgery, if a patientfails to move the joint, tissue around the joint will become stiff and scar tissue will form, resulting in a joint with limited range ofmotion. By repeatedlyexercisingand extending the affected joint through a prescribed arc of motion for an extended period of time, theOptiFlex 3 CPM Unit lessens the adverse effects of immobilization and trauma on the knee joint. All of our equipment is patient-ready with a one year warranty.
