After orthopedic surgery, part of an effective therapy program includes movement to keep the affected area from becoming stiff and scar tissue from forming.

If the joint does become stiff and scar tissue forms, it can result in a joint with limited range of motion, which can take months of physical therapy to recover from.


Continuous passive motion (CPM) devices are used during rehabilitation after surgery to:

  • Control post-operative pain
  • Reduce inflammation
  • Provide passive motion to a specific area
  • Protect the healing process
  • Prohibit the area from becoming stiff
  • Prevent the development of scar tissue
  • Optimize the recovery process

A CPM device will continuously move the joint through a controlled range of motion. The specific range is dependent upon the joint, but in most cases the range of motion is increased over time.


Sanus DME offers post-surgical CPM in form of OptiFlexK1, which is an easy-to-use device that patients can learn to operate and use within the comfort of their homes. OptiFlexK1 is used after many orthopedic surgeries, including knee and ACL surgery, to prevent stiffness, scar tissue and loss of motion to make recovery as comfortable and effective as possible.


Sanus DME representative will typically deliver the OptiFlexK1 device directly to a patient’s home and show them how to use it. If a patient has any questions or challenges using the device, they will have access to their Sanus DME rep by phone or email as well as 24/7 support through the patient portal.

Providing and supporting a total care experience that meets and exceeds patient needs and goals, including post-surgical care. With extensive joint surgery, there will always be some scar tissue. However, with OptiFlexK1, we see to minimize the development of scar tissues that can be painful, maximize range-of-motion and accelerate recovery and the ability to return to daily activities.
