PAPrKA is a University of Manchester-led study investigating physical activity trajectories before and after knee replacement using smartphone and wearable data.

Clinical Context and Unmet Need

Knee arthroplasty is a common procedure, but recovery outcomes vary widely. Traditional assessments rely on clinic visits and questionnaires, which do not fully capture real-world recovery patterns.

Study Design and RADAR-base Integration

• Ongoing recruitment
• Population: patients undergoing knee replacement
• RADAR-base supports:
  • Smartphone-based activity tracking
  • Wearable data integration
  • Longitudinal real-world monitoring

Solution

RADAR-base enables continuous capture and integration of real-world activity data, providing objective insights into recovery patterns.

Impact

• Changes in service delivery: Remote post-operative monitoring
• Improved outcomes (potential): Better recovery understanding
• Collaboration: Multi-site research integration
• Operational excellence: Digital measurement innovation
• Patient involvement: Passive and active data contribution

PAPrKA highlights how RADAR-base enables objective, real-world measurement of recovery following surgery. If translated into practice, this could support personalised rehabilitation, improved patient counselling, and enhanced surgical outcomes.
