As your range of movement improves you learn to properly activate the muscles to enable you to get strong and use your new range of motion in daily life.
As your range of movement improves you will learn to properly activate your muscles to get strong and use your new range of motion in daily life.
It is a result of an exaggerated inflammatory immune response to surgery – scar tissue continues to build – unless you perform daily high intensity stretching to break it down.
Patients can now benefit from high-intensity stretching daily at home using effective, natural, specific and targeted stretching techniques.
You are in control of the intensity of your stretch and can see and feel the progress. You know its working!
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. In your follow-up sessions, your progress will be monitored, range of motion recorded and any issues which may arise worked through together.
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.
Results vary based on starting range and ability.
Some progress faster and regain more mobility. Less severe cases will progress more quickly.

STAK Knee Stretcher Fact
Over 98% of patients would recommend our programme to a friend.
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.”
“In a clinical trial patients using the STAK increased their ROM on average 30° compared to receiving standard physiotherapy gained only 8°. The STAK patients also reported greatly reduced knee pain.”
“The device can be considered a cost-effective and valuable treatment following TKR. This is likely to increase the overall satisfaction rate and has potential to reduce the need for MUA.”
