Revolutionising Osteoarthritis Care: How MAI Motion Improves Knee Function Assessment

Introduction: Tackling the Challenge of Knee Osteoarthritis

Osteoarthritis is one of the most common joint conditions globally, impacting millions—especially in the knees. It brings persistent pain, stiffness, and can make everyday activities like walking or climbing stairs a struggle. Accurate assessment of knee function is crucial for diagnosing osteoarthritis and crafting effective, personalised treatment plans. Yet, traditional assessment methods often fall short, focusing mainly on joint structure rather than how the knee moves in real life. Enter MAI Motion : a cutting-edge technology that’s transforming how healthcare professionals examine knee health. By capturing detailed movement data, MAI Motion is opening up new possibilities for both doctors and patients.

With healthcare systems stretched thin and many low-risk patients—including those with suspected osteoarthritis—unable to access timely evaluations, innovative and accessible assessment tools like MAI Motion are more essential than ever.

Understanding the Knee and Osteoarthritis

To appreciate how MAI Motion makes a difference, it’s helpful to understand the knee’s complexity. This joint is a marvel of bones, cartilage, ligaments, and muscles working in harmony to provide both movement and stability. Osteoarthritis erodes the smooth cartilage that cushions the joint, leading to pain, swelling, and decreased mobility. Simple tasks can become significant challenges, directly affecting quality of life. Early diagnosis is vital, as timely intervention can slow joint damage and ease symptoms.

Traditional tools like physical exams, X-rays, and MRIs are valuable, but they mostly offer snapshots of the knee’s structure. They often miss how the joint performs during real-world movements. This is the gap MAI Motion fills—capturing the true performance of the knee in action and providing clinicians with insights into a patient’s movement capabilities, beyond what static images can reveal.

What Is MAI Motion and How Does It Work?

MAI Motion is an advanced technology that brings knee assessment into the digital age by analysing real-time movement. Using high-tech sensors and smart algorithms, it tracks knee angles, speed, and the distribution of weight across the joint during everyday activities. Think of it as a 3D, dynamic motion picture of how your knee actually works—not just how it looks when still. With this in-depth view, clinicians can spot subtle issues in knee movement that are often missed by traditional assessments. The result is a personalised movement profile, empowering targeted treatment and smarter rehabilitation.

Impressively, MAI Motion can leverage standard video equipment—using simple RGB or more advanced RGB-D (Red Green Blue Depth) image sequences—to estimate human movement with accuracy. This makes sophisticated knee analysis more accessible and less dependent on expensive, specialised machinery.

The Benefits of MAI Motion in Clinical Care

Integrating MAI Motion into osteoarthritis care offers numerous advantages. Its dynamic, detailed analysis gives clinicians a clearer picture of joint function, supporting more accurate diagnoses and tailored treatment plans. Motion analysis can detect early changes in gait or weight distribution that may signal the onset of joint issues—long before they become obvious. This allows for early intervention, from targeted physiotherapy to personalised surgical planning, enhancing treatment success rates.

MAI Motion is also non-invasive and provides immediate results, making it an ideal tool not only for diagnosis but for ongoing monitoring through rehabilitation . A recent validation study showed that the MAI Motion system could gather robust biomechanical data with a streamlined three-repetition approach, rather than the traditional five. This reduces patient fatigue without sacrificing accuracy, making the process more patient-friendly and clinically practical.

Looking Ahead: The Future of Knee Assessment

Technology like MAI Motion is paving the way for an exciting future in osteoarthritis care. Research is ongoing to make these systems even smarter by integrating artificial intelligence that could predict disease progression or optimal treatments. There’s also potential to combine MAI Motion with wearable devices, allowing continuous tracking of knee health outside the clinic. As these tools become more widely adopted, knee care will shift from a reactive to a proactive, personalised model—offering patients better and more adaptable support.

Importantly, researchers have found that small differences (up to 10 degrees) in knee motion range could help better identify changes in walking patterns or track progression over time. Insights like this are shaping a future where technology leads to earlier intervention and improved quality of care.

Conclusion: A New Era in Osteoarthritis Care

MAI Motion signals an important shift in how we understand and treat knee osteoarthritis . By moving from static images to dynamic, individualised motion analysis, clinicians gain a much deeper understanding of the joint’s health. This leads to more precise diagnoses, better treatment strategies, and ultimately, a higher quality of life for patients. As this technology evolves, it brings hope for a future of healthcare that’s more accurate, effective, and tailored to each person. With MAI Motion at the forefront, the prospect of living better with osteoarthritis has never looked brighter.
