How it works
No complex dashboards. No wearable required. Just what matters — in 90 seconds a week.
A single number showing how your joints compare to your chronological age. 7 inputs at onboarding. Updated from 3 questions weekly.
Is your Knee Age going up or down? An 8-week trend shows whether your lifestyle is protecting or ageing your joints.
Not twenty suggestions. Exactly three specific, evidence-based actions for this week — drawn from the R.E.P.A.I.R.™ framework built across 25 years of clinical practice.
As your behaviour improves, your score improves. The goal: make your Knee Age lower than your chronological age. Then keep it there.
Why it matters
The science
Every action is derived from six evidence-based pillars developed across 25 years of clinical orthopaedic practice.
Score weightings will be calibrated against clinical outcomes data during the validation phase.
