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.

Its beneficial to have physiotherapy support for guidance and monitoring progress. Your physio can help tailor the use of the STAK to your specific needs.

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.

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.
