Clinician reviewing knee imaging alongside motion-derived data for early osteoarthritis stratification
Growth Catalyst · The Keep Clinic

KNEE-MotionMRI

Stratifying knee osteoarthritis before the damage shows.

A non-invasive, clinically-driven, AI-powered platform proposed by The Keep Clinic that integrates two previously disconnected domains: real-time biomechanical motion analysis and MRI-based structural imaging.

The dual-modality approach is designed to enable earlier, more precise detection and stratification of knee osteoarthritis before structural damage occurs — delivered as an app using a mobile phone camera.

Feasibility Programme

The Clinical Challenge

A degenerative condition, usually caught late.

Prevention and management of knee osteoarthritis focuses on healthy lifestyles and reducing joint overuse. But left untreated, it progresses to knee replacement. Current diagnostic methods rely heavily on static MRI imaging and subjective assessment that often detect the disease only after irreversible joint damage has occurred.

528m

People living with osteoarthritis globally, with knee joints most affected at 365 million

5.4m

People affected in the UK in 2020, expected to reach 6.4 million by 2030

1 in 3

GP visits accounted for by knee osteoarthritis, alongside over 100,000 knee replacements a year

Today’s Pathway
  1. 01

    Static MRI imaging

    The standard tool for assessing knee soft tissues — meniscus and cartilage — but manually interpreted and captured at rest.

  2. 02

    Subjective assessment

    Often detects the disease only after irreversible joint damage has occurred.

  3. 03

    Late-stage detection

    No scalable or accessible tool captures early functional decline — instability or poor control — that precedes visible MRI change.

  4. 04

    Long waiting lists

    Untreated degeneration leads to knee replacement, with lengthy waits and major NHS expenditure.

The Gap

Siloed systems, one-sided answers

Current diagnostic systems offer either static imaging or surface-level motion analysis. Nothing scalable correlates internal joint structure with external motion function — the correlation that would move screening from late-stage to early-stage.

This programme is a six-month feasibility study. Its purpose is to test whether that correlation exists strongly enough to build on, not to deliver a finished diagnostic.

The Innovation

Proprietary algorithms at three levels of the stack

Rather than relying on manually interpreted MRI results, KNEE-MotionMRI is intended to provide an objective method to quantify multi-modal data and stratify patients for faster diagnosis and more efficient treatment planning.

01

Computer vision

Real-time 3D motion capture from a standard smartphone camera, with no specialist equipment.

02

Deep learning

Motion pattern recognition and MRI feature extraction across both modalities.

03

Fusion layer

A novel layer synthesising functional and anatomical data into a comprehensive digital health phenotype.

Comprehensive overview

A fuller picture of a patient’s condition, accelerating early monitoring and intervention.

Affordable and accessible

Assessment conducted in patients’ homes on everyday devices, widening access for elderly and disabled patients who cannot sustain long appointments at specialist facilities.

Fewer routine scans

Reduced need for frequent MRI through earlier detection and identification of high-risk patients.

Objective quantification

Automatically detecting and quantifying structural lesions via motion, intended to increase accuracy while reducing human error.

Six Months, Four Work Packages

Beyond the Project

What six months is meant to unlock.

The application positions the project as directly supporting NHS Long-Term Plan goals of early intervention and diagnostics, with these intended outputs:

  • A validated clinical use case for early knee osteoarthritis stratification.
  • Demonstrated motion–MRI correlation feasibility.
  • A clear regulatory and IP roadmap forming the foundation for long-term clinical impact.
  • Positioning for a seed-stage investment round to expand into hip and spine modules and virtual MSK care.

Application-Stage Evidence Boundary

What the application does — and does not — establish.

This page describes a funding application for a feasibility study. The cost, speed and market figures in it are proposals and projections, not measured results.

Supported by the application

  • A six-month, £48,859 feasibility application led by The Keep Clinic Limited, proposed to start 1 November 2025.
  • The Keep Clinic is a CQC-registered private medical clinic (Provider ID 1-8692595311) with ethics approval ref 2021_7084 for data collection.
  • In-kind contribution of MRI scans (valued at £450 each) and 3,500+ existing motion analyses.
  • Four work packages covering project management, clinical use-case validation, motion–MRI correlation feasibility, and a regulatory and IP roadmap.

Not established by the application

  • That KNEE-MotionMRI has demonstrated diagnostic accuracy, clinical effectiveness or the stated cost savings.
  • That the £5-per-scan price, sub-two-minute report time or Class II device registration have been achieved in practice.
  • That UKCA/CE marking, NHS adoption or commercial deployment have been completed — WP4 is a roadmap, not an approval.
  • That the application was funded, or that the market and revenue projections in it have been realised.
