Description
STAK Knee Stretcher is a clinically proven medical stretching device designed for home use, enabling patients to perform effective daily stretching to regain their full range of movement -both bending (flexion) and straightening (extension) -after knee replacement, major knee surgery, or injury. The standard STAK tool is highly effective at restoring knee flexion, while our new high-intensity extension add-on provides a superior solution for those struggling with knee straightening.
Lightweight and easy to use, the STAK is supplied with an accompanying chair that ensures optimal, comfortable high-intensity stretching. It is both self-motivating and empowering, helping patients achieve the best possible outcomes.
The STAK allows you, the patient, to generate high-intensity stretches that break down scar tissue in your knee, reducing stiffness and pain. As this scar tissue remodels, new healthy tissue forms, restoring your range of movement. Improvements are often seen within days, and we recommend an 8-week treatment period for achieving a 30° improvement .
STAK Specialist Physio Sessions
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.
For those with severe extension loss, our high-intensity extension add-on specifically targets knee straightening deficits. Even a small loss of extension - as little as 5° -can significantly impact walking patterns, increasing strain on the quadriceps, leading to pain, weakness, and even episodes of knee giving way. Research has shown that limited knee extension alters gait mechanics, disrupts shock absorption, and contributes to long-term joint stress. This advanced STAK component provides a superior, highly effective solution for restoring full extension, improving walking efficiency, and preventing compensatory muscle overuse.
