OptiFlex 3 CPM Accessories & Patient Pad Kits

The OptiFlex 3 is a continuous passive motion (CPM) system used in knee rehabilitation, and this collection focuses on the replacement pads and accessories that keep those units clean, comfortable, and ready for the next patient. Whether you manage a rehab clinic, an orthopedic practice, or a home recovery setup after knee surgery, having fresh patient contact surfaces on hand is what keeps therapy sessions comfortable and hygienic.

CPM therapy relies on the limb resting against the machine for extended, repetitive movement cycles, so the pad interface matters more than most people expect. Worn, compressed, or soiled padding leads to skin irritation and reduced patient tolerance during long sessions. That's why the OptiFlex 3 CPM Patient Pad Kit (20533) uses a soft sheepskin/fleece surface — it cushions bony prominences, wicks moisture, and distributes pressure gently along the leg through each flexion and extension cycle. Designed specifically to fit OptiFlex CPM units, the kit replaces the components that contact the patient directly, making it a natural single-use or single-patient consumable for infection control.

A common question from clinics and caregivers is how often these pads should be replaced. As patient-contact items, pad kits are typically swapped between patients or when the fleece shows compression and matting, since sheepskin loses its cushioning and moisture-management properties over time. Home users renting or owning an OptiFlex unit during post-operative recovery should keep a spare kit available so therapy is never interrupted by a worn or soiled pad.

When ordering, confirm the kit is compatible with your specific OptiFlex model — the 20533 kit is built for OptiFlex CPM units. If you're outfitting a broader rehabilitation program, browse related device families such as the 3 Series to round out your equipment and consumables in one place.
