The Passive Knee Stretch Device:
A Therapeutic Device Aiding Recovery from
Hip Bursitis and Knee Bursitis

This Device is Currently Used in Hundreds of Physical Therapy Clinics and Hospitals in Canada - This Same Device is Now Currently Available for Use in the USA

passive stretching accelerates recovery

Well, I must say that I spent a long time searching for this treatment option. I was introduced to a carpenter (I'll call him Paul) about 6 months ago that had designed and created this device especially for his friend Earl that was attempting to recover from a bad knee injury. Earl was instructed by the doctor to put his foot in a plastic garbage bag while sitting. Once the foot was in the bag, he should stretch and strengthen his knee by sliding his foot forward and back across the floor. Earl complained of the intense pain he encountered when the bag inevitably creased and folded thereby jerking his knee, and soon after that, the first Knee-Flex® Passive Knee Stretch Device was created.

Earl's knee recovered 10 years ago, but Paul continues making more and more of the Knee-Flex® devices every year - mostly for therapy clinics and hospitals in Canada that keep asking for his Knee-Flex® Device.

Knee and Hip Stretching
Without the Strain

This is the final essential tool for knee and hip injury recovery. The Knee-Flex® Passive Knee Stretch Device already has a ten year successful track record in Canadian physical therapy clinics and hospitals. It is already proven to be highly valued by Canadian physical therapists as a major recovery tool for patients suffering from meniscus injuries, knee ligament injuries and post knee-surgery recovery.

The value of this device cannot be underestimated. Anyone suffering from knee joint and hip joint pain knows the importance of flexing the knee joint smoothly and without excessive load. The Knee-Flex® Passive Knee Stretch Device operates without the use of tension bands or any added force aside from the weight of your own leg. Basically, if you are on the road to recovery from a knee injury or hip injury, this device is the first thing you would use to start gaining flexibility back in these joints.

As you slowly start to use the Knee-Flex® Passive Knee Stretch Device more frequently, you should find that your joint recovery will accelerate as well. The increased joint flexing will help connective tissue to regain elasticity; the motion will increase blood flow to the recovering injury as well, aiding in the healing process. The Knee-Flex® Passive Knee Stretch Device is what lies between bedridden immobility and crutches. Using crutches too quickly can be detrimental to your recovering lower body joints, as many patients can certainly attest. A quick slip on the crutch can easily result in your weakened joint bearing your full body weight, often causing a worse re-injury or perhaps a fall.

This seemingly simple device has assisted in the recovery of thousands of patients that have suffered many various injuries. Once a patient is on the path to healing, this device assists the patient in making a fast and full recovery. As with every product we sell, the Knee-Flex® Passive Knee Stretch Device is an FDA Registered Medical Device.

The Knee-Flex® Passive Knee Stretch Device is commonly used to aid in the recovery stage of:

  • Patients recovering from surgery (ie. knee replacement, lathroscopic knee and hip surgery, hip replacement).
  • Patients recovering from a serious knee ligament injury
  • Patients recovering from a serious Hip Injury such as Illiotibial Band Syndrome or Acetabular Labral Tear
  • Patients recovering from Hamstring Pulls, Hamstring Strain, Calf Pulls, Calf Strains
  • Patients recovering from knee or hip dislocations

The Knee-Flex® is a Medical Device - Please Speak with Your Physician or Physical Therapist About Whether this Device is Suitable for Aiding Your Recovery

knee flex is better than heel slides

Before making the transition to crutches, physical therapists prescribe gentle stretching of an injured knee or hip, and if no device is available, they usually prescribe heel slides. They don't prescribe this to annoy you - it is in fact the most important part of knee injury recovery. You probably know of someone that chose not to do these stretches as it is common - and they paid a high price for it. By not listening to the therapist (ie. not stretching), there is a huge chance of re-injuring your knee or even sustaining an injury greater than the original injury ever was.

The Knee-Flex® Passive Knee Stretch Device was created because the heel was not sliding smoothly enough, causing re-injury and additional pain. Physical Therapists encounter the same issues every day when attempting to work with patients who are undergoing therapy from a serious knee or hip injury. This is why a growing number of therapists in Canada purchase these same devices for their own clinics. For patients recovering from serious pain, it allows a more controlled and comfortable method to stretch and strengthen the muscles and ligaments in both the hip and knee joint. The sliding mechanism is extremely smooth and durable, as well as linear - something that becomes very important in such cases.

Proper usage of the Knee-Flex® Passive Knee Stretch Device will aid you in increasing the elasticity and strength of your injured joint. After using the Knee-Flex® Passive Knee Stretch Device over time, your knee joint will be better prepared to handle higher and higher loads. Eventually you will reach a stage where your knee joint can handle crutches or standing for longer and longer period of time. This is the final stage of recovery and depending on age, the nature of the injury, your weight and many other factors, it can take the longest time to complete. But remember, for knee injuries, it pays to be patient! Rushing your knee injury recovery almost never pays.

When combined with ColdCure Wrap® therapy and BFST Wrap® therapy, the Knee-Flex® Passive Knee Stretch Device allows you to comprehensively treat most knee injuries and hip injuries with the most effective home treatments that are available.


The Knee-Flex® Passive Knee Stretch Device is an FDA Registered Medical Device and is suitable for repetitive, industrial usage in hospitals and therapeutic clinics. This device is deemed safe to use without medical assistance and as such is also available for use at home. This device is manufactured with a durable, easy glide track and is constructed almost completely from Canadian hardwoods.

If you aren't a professional athlete but you have a soft tissue knee injury (just like the injuries they get all the time), shouldn't you be getting the best treatment too? Of course you should - and you can. Pro Athletes have unlimited and timely access to Trainers and Physical Therapists that are actively working to get them healed as fast as possible. In almost all cases, Trainers and Therapists will have the patient undergo a treatment regimen that involves using a joint stretch device very similar to the Knee-Flex® Passive Knee Stretch Device.

Knee Flex Usage - Key Points to Keep in Mind

The Knee-Flex® Passive Knee Stretch Device will become an invaluable tool in your knee/hip recovery therapy. When used correctly, this device can strengthen and stretch four different muscle groups as well as stimulate blood flow in the joint for added recovery speed. Once you have spoken with your physician or physical therapist and determined that they approve of heel slide exercises, only then should you begin using the Knee-Flex® device. Once using it, here are a few things to consider:

  • On the first session, loop a belt or bathrobe loop around your foot to assist your efforts. Once you find this is not needed then stop using the loop.
  • Do not fret if you cannot flex your knee. Do what flexion you can and this machine should assist in increasing your range of motion over the long run.
  • Set up the machine in a stable area free from obstruction. Most of our users find a pillow is very helpful as well for sitting/lying on.
  • Always use the machine slowly and in a controlled manner. Quick, jerky movements are not helpful and will only cause added problems.
  • When placing your heel on and off the machine, use your arms to lift it. This will keep the stress off your injured joints.
  • Always follow the manual.

Your Physician or PT will be able to let you know When it is Safe to Start Using the Knee-Flex®


When used properly, the Knee-Flex® has a proven track record of assisting in the speedy recovery of many patients. As I have said on the home page, I have spent a long time searching for this treatment option. This is without doubt, an effective tool for knee and hip recovery. Once a patient deals with the swelling and inflammation through use of the ColdCure Wrap® then begins the BFST® process through the use of the BFST Wrap® it is time to take the third and final step to recovery by beginning a rehabilitation stretching regimen. The safest and most effective way we know to stretch the knee is through use of the Knee-Flex® Passive Knee Stretch Device

Bursitis Inflammation Facts:

Bursitis is the inflammation or irritation of the bursa.

Bursitis is most often caused by repetitive, minor impact on the area, or from a sudden, more serious injury.

Bursitis high-risk activities include gardening, raking, carpentry, shoveling, painting, scrubbing, tennis, golf, skiing, throwing, and pitching.

If bursitis persists and is left untreated, calcium deposits can form within the bursae. These calcium deposits limit range of motion and can lead to a permanently stiff joint.

Incorrect posture at work or home and poor stretching or conditioning before exercise can also lead to bursitis.
