Dr Sara Aspinall, a leading expert in arthrofibrosis with nearly 20 years of experience in physiotherapy and orthopaedics, is the only physiotherapist in the world with a PhD in arthrofibrosis. Her passion for exceptional patient care led to the development of the STAK tool, designed to provide consistent, high-intensity stretching for knee stiffness and pain. The STAK programme helps patients break down scar tissue, reduce pain, and regain range of motion with daily, controlled stretching at home. Dr Aspinall works closely with NHS and private hospitals, training teams to manage challenging knee cases and ensuring optimal outcomes for patients. Through collaborations with physiotherapy clinics, osteopaths, and chiropractors, STAK Orthopaedics delivers lasting improvements in function and quality of life for patients across the UK.
