UP TO 60° RANGE OF MOVEMENT GAIN
weeks programme
VERY SATISFIED WITH TREATMENT
20% of patients will experience stiffness and pain following knee replacement. The STAK offers a new approach to treating your problem. It enables you to carry out effective intense stretching of your knee daily in your own home. Standard physiotherapy exercises simply do not achieve the same results (only 10% of the torque of the STAK).
The STAK can help you after recent surgery or even many years later. It can transform your life whether you have severe motion loss or simply want to get back to higher levels of activity and the things you love doing!
The gadget definitely works! The STAK exercise has removed much of the pain in my knee, there's a massive increase in movement and I'm walking normally after1 week!
To get my knee bending to its full potential that I have got now has to be down to The STAK tool because with normal exercises it just wouldn't work.…….. the STAK is more intense.
My knee is bending 100% better than it was… I can walk 7-8 miles! On holiday the walking is tremendous…. I‘ve climbed a lighthouse with 137 stairs!
After using the STAK tool I know I can keep up with my friends, just after 4 weeks I could feel a huge difference
They sent me home and I was nowhere near 90° so for me having this STAK would have been ideal right from the from the beginning.
After 6 weeks I’m now back riding my bike, coaching netball and I’ve got my life back!
After 1 week the STAK has made a huge difference. My Physio was amazed! ..and its all down to the STAK. You can stretch effectively yourself using your body weight, before I had nothing.
I feel that it's been very useful, it's great and should be in physio departments for people to use.
I didn't expect it to help this much when I was already 6 months after surgery but it's brilliant and feels much stronger!
The STAK was fantastic! It held my knee in place, you knew you were doing it right. It makes you want to do more and gives you encouragement and confidence so you can do it.
She only had 62° flexion, I spoke about the STAK and I was surprised that she had reached 108° flexion just a few weeks later
Stiffness in knee replacements is a top priority for management, ongoing innovation is crucial. The STAK really enhances our non-surgical approach to this challenging issue.
It’s just a fantastic, low cost and really effective alternative treatment compared to the traditional treatments we had before. Since we have been using the STAK tool the MUA rates have fallen.
The STAK tool provides a measurable outcome improvement. The patients get and maintain extra functions over and above what they normally get.
The STAK tool can help with patients after recent surgery or even many years after surgery.
Patients can perform high-intensity stretching in their homes, akin to having a personal physiotherapist. Patients maintain control over the intensity of the stretch and can clearly see progress.
In the most challenging cases where traditional methods, such as extensive physiotherapy, hydrotherapy, continuous passive motion (CPM) machine hire, and manipulation under anaesthetic, fell short the STAK proved to be the solution.

You may be one of the 20% of patients suffering from arthrofibrosis (stiffness and pain) following the trauma of knee surgery or injury.
Your immune system is overreacting causing scar tissue to be deposited in your knee joint.
The scar tissue will continue to build resulting in severe stiffness, pain and loss of range of movement, impacting severely on your quality of life.
The STAK enables you to generate high-intensity stretches which will break down the scar tissue in your knee which is causing you stiffness and pain. Unfortunately, standard physiotherapy exercises do not enable you to generate the intensity of stretch needed to break down the scar tissue.
Weekly online coaching sessions helping you to use the STAK tool to aid your recovery.
STAK Orthopaedics offer physiotherapy support for a range of other injuries and rehabilitation.
STAK work with hospitals to help patients access improved recovery and mobility after knee surgery. You can hire STAK for 6 months to trial with your patients.
In a clinical trial lasting 8 weeks arthrofibrosis patients using the STAK gained on average 30° range of movement compared to patients receiving standard physiotherapy who gained only 8°.
“The STAK tool increases ROM and function whilst reducing stiffness and pain. This study shows the STAK tool would benefit clinical practice for a cost-effective and professional treatment for arthrofibrosis.”

The STAK is a home treatment device designed to help patients regain knee range of movement and reduce stiffness and pain following knee surgery. It offers intense stretching capabilities that break down scar tissue, providing better results than standard physio exercises.
The STAK enables you to generate high-intensity stretches, breaking down scar tissue in the knee joint. This process helps reduce stiffness and pain, allowing new, healthy tissue to form and restoring your knee’s range of movement.
It is recommended to use the STAK device as part of a treatment programme for 4 to 8 weeks, depending on the severity of your stiffness and how long after surgery you start treatment. The majority need 8 weeks, but if you already have 100˚4 weeks should be adequate.
Yes, the STAK can be beneficial even many years after knee surgery. The latest to date is 6 years following TKR. If suffering severe stiffness an extra 4 weeks may be required but the average 30˚ increase still stands.. STAK helps patients with severe motion loss or those looking to improve their activity levels and quality of life.
You can start using the STAK shortly after your knee replacement surgery once clips have been removed. Early intervention with the STAK can pre-emptively address stiffness, yielding exceptional patient outcomes. If wanting to use prior to 2 weeks following surgery please consult Dr Sara Aspinall.
Yes it is beneficial to have physiotherapy support for guidance and monitoring progress. Your physio can help tailor the use of the STAK to your specific needs.
Yes, you can take the STAK to your local physio. We will supply them with a short physio training video. They can assist you in incorporating it into your rehabilitation programme and guide you as you progress.
Absolutely. The STAK can be integrated into your hospital physio sessions. Your hospital physio can help you use the STAK effectively as part of your rehabilitation programme, ensuring you achieve the best possible outcomes.
The frequency of use will depend on your individual treatment plan. Typically, patients use the STAK device 3 times a day for optimal results. If you have less severe stiffness 1-2 times may suffice.
Virtual STAK physio sessions provide remote support and guidance from a STAK Specialist Physiotherapist. They will monitor your progress, adjust your treatment plan as needed, and ensure you are using the device correctly.
Yes, the STAK is designed for ease of use. It comes with clear instructions for self-setup, enabling you to perform effective stretches at home.
The STAK generates high-intensity stretches necessary to break down scar tissue, which standard physio exercises cannot achieve. In clinical trials, patients using the STAK experienced an average gain of 30° in range of movement over 8 weeks, compared to only 8° with standard physio.
Yes, a clinical trial published in The Bone & Joint Journal showed that arthrofibrosis patients using the STAK experienced a significant average gain in range of movement, far surpassing the results of standard physio.
The STAK has received praise from surgeons and physiotherapists. EG Professor Andrew Toms from the Exeter Knee Reconstruction Unit highlighted its ‘unique effectiveness in improving non-surgical approaches to treating knee stiffness’ (see testimonials on our website for more details).
In your first session, we will discuss your goals and what activities you would like to return to. Your knee will be assessed, and your range of movement measured accurately using an App (you will be sent a copy of this if you wish). You will be taught how to complete the STAK programme and all elements will be completed by yourself. You will be shown how you can measure your progress. We will discuss several important elements of the programme and how to tailor it to your individual need. You will feel improvements in your knee after the first session.
Most insurance companies will cover the physiotherapy sessions such as AXA Health, Vitality Health, Simply health, Benenden Health, Westfield Health. Please inform us if you plan to use insurance and we can assist.
Some will include STAK hire but please reach out to your insurance company and check with them.
If not please contact us and we may also be able to help get the insurance company on board.
