A ground-breaking research collaboration between NHS Golden Jubilee and the University of Glasgow aims to improve recovery outcomes for patients undergoing knee replacement surgery.

ROBUST-KNEE (Radar-based system fOr gait monitoring versus camera-Based systems integrated with testing of blood-flow occlUsion Strength Training in total KNEE arthroplasty) addresses a critical need for patients who face significant pain, reduced mobility and muscle weakness while waiting for surgery.

The study will focus on a novel application of an exercise therapy and advanced movement monitoring to improve patient outcomes. This includes:

• Testing the effectiveness of Blood Flow Restriction Training (BFRT) – a proven sports medicine technique – as a method of building muscle strength through gentle exercises. This is especially valuable for knee osteoarthritis patients with pain and mobility limitations who may find traditional exercises too challenging.
• Developing and validating a radar-based system to track patient movements in real time. This cutting-edge technology eliminates the need for cameras or wearable devices, ensuring patient privacy and enabling convenient monitoring from home.

The study aims to improve the muscle strength and mobility of patients undergoing knee replacements leading to better recovery and outcome after surgery. Additionally, the study is aiming to validate novel radar technology for in-home monitoring of mobility without active patient involvement.

Dr Swati Chopra, Orthopaedic Research Physiotherapist at NHS Golden Jubilee, commented: “ROBUST-KNEE represents a bold step forward in patient care by combining advanced radar technology with tailored exercise programs. This creative solution shows how fresh perspectives can transform clinical research through technological innovation.

“The privacy-preserving system allows for real-time activity monitoring without requiring cameras or wearable devices, marking a significant departure from traditional approaches.”

Professor Jon Clarke, Orthopaedic Consultant at NHS Golden Jubilee, added: “This research reflects NHS Golden Jubilee’s commitment to developing innovative solutions that improve patient outcomes while addressing the unique challenges faced by those awaiting surgery.

“Once proven, this technology and training is easily scalable with potential applications across various patient groups across Scotland and further afield.”

The study follows on from the recent strengthening of a strategic academic partnership between NHS Golden Jubilee and the University of Glasgow, reflecting a shared commitment to advancing medical research.

Funded by the prestigious Medical Research Council Impact Acceleration Award (MRC-IAA) after a competitive review process, the study will utilise the hospital's motion analysis lab for clinical validation of innovative interventions and a novel radar system for monitoring patients’ walking patterns objectively. It will also fund additional state-of-the-art equipment for this and future studies, benefiting an ever-growing population of patients with osteoarthritis.

Dr Julien Le Kernec, of the University of Glasgow’s James Watt School of Engineering, said: “ROBUST-KNEE is just one example of how, through this partnership with NHS Golden Jubilee, we’re laying the groundwork for advancements that will benefit patients across the NHS and beyond.

"This project exemplifies the power of academic and clinical collaboration in tackling critical healthcare challenges. By combining state-of-the-art technology with novel therapeutic approaches, we hope to transform how patients prepare for and recover from surgery."

As the study progresses, the findings from ROBUST-KNEE will hopefully shape the future of knee replacement recovery, as well as establishing a model for integrating innovative technologies and therapies into routine care.
