At STAK Orthopaedics, we are dedicated to revolutionising the treatment of knee stiffness and pain. With nearly 20 years of experience in physiotherapy and orthopaedics, Dr Sara Aspinall is the UK’s foremost expert in arthrofibrosis. As the only physiotherapist in the world with a PhD in arthrofibrosis (knee stiffness and pain), Dr Aspinall combines cutting-edge scientific knowledge with a passion for exceptional patient care.

The STAK tool was born out of frustration with seeing the gains made during physiotherapy sessions being lost by the next appointment. Treating patients with stiff knees highlighted the need for a solution that provided consistent, high-intensity stretching every day.

With the STAK tool, patients can benefit from controlled, high-intensity stretching at home, naturally breaking down scar tissue while reducing pain and stiffness. It’s like having your own physiotherapist available at all times, offering convenience and exceptional care. With the tailored and proven STAK programme, you can take charge of your recovery, improve your range of motion, break down scar tissue, regain strength, enhance neuromuscular control, and experience long-lasting improvements in function and overall quality of life.

At STAK Orthopaedics, we also collaborate with NHS and private hospitals, training their teams in the use of the STAK tool and sharing our expertise in managing challenging cases of knee stiffness. Our partnerships extend to private physiotherapy clinics, osteopaths, and chiropractors, ensuring the best outcomes for patients across a wide spectrum of care.
