OptiFlex – The Story Behind the OptiFlex Knee CPM

When the Chattanooga Group first began research on continuous passive motion devices for the knee, we found a market that was staid and stagnant. Other manufacturers thought their designs needed no improvement, though the word from clinicians indicated otherwise. As a result, our engineers went to work, listening to the advice from physicians, nurses and therapists to find features that were needed. This is how the OptiFlex Knee CPM was born. It’s a true innovation! Features like Progressive ROM, Oscillation Zone, Fast Back and Comfort Zone didn’t exist before OptiFlex. Imagine the difference these features can make in your patients, enhancing comfort, compliance and outcome. Our handheld pendant is ergonomically designed with easy-to-use buttons, back-lit display for maximum visibility, multiple language interface, context sensitive help and even a tough Santoprene bumper and seal.
