CPM Knee Machine Continuous Passive Motion Physical Therapy Rehab

A continuous passive motion (CPM) knee rehabilitation device that moves the knee through a controlled range of flexion and extension without active muscle effort from the patient. A CPM for knee replacement and other knee procedures, it fits continuous passive motion knee replacement rehabilitation protocols and supports prescribed range-of-motion exercises to maintain joint mobility and reduce post-operative stiffness. Microprocessor-controlled with adjustable settings and an automatic safety reversal, it suits hospitals, rehabilitation centers, physiotherapy clinics, and home use under professional guidance.

How to Use

1. Position — place the machine on a stable, flat surface such as a hospital bed or treatment couch.
2. Adjust supports — set the thigh and calf supports to the patient's leg length, aligning the knee with the machine's pivot point.
3. Secure the leg — rest the leg on the supports and fasten the straps so the limb is stable without restricting circulation.
4. Set parameters — switch on and use the hand controller to set the prescribed flexion, extension, speed, and duration.
5. Start — begin the passive cycle and watch the first movements to confirm alignment and comfort.
6. Monitor — observe the patient throughout; stop immediately for discomfort, unusual resistance, or any problem.
7. Finish — at session end, stop the machine, release the straps, and carefully remove the leg.

Where It's Used

A CPM for knee replacement and post-surgical knee rehabilitation tool, it manages post-operative stiffness after total or partial knee replacement, ACL and PCL reconstruction, meniscus repair, and post-traumatic stiffness. Used in hospitals, rehabilitation centers, and physiotherapy clinics, and at home when prescribed by a qualified healthcare professional.

Handling & Safety

1. Professional guidance — operate this CPM orthopedic machine per the prescribed rehabilitation protocol and the healthcare professional's instructions.
2. Inspect before use — check the frame, leg supports, straps, power cord, and hand controller; don't use if anything is damaged or loose.
3. Keep it clean — wipe with a soft cloth and hospital-approved disinfectant after each use; keep liquids out of the motor housing and controller.
