Abstract
Demo abstract. Prospectively collected registry data on consecutive primary knee replacements were analysed for revision, radiolucent lines and PROM trajectories at two years.
Description
Patients were not randomised; implant choice followed surgeon preference and bone quality assessment, and this confounding is stated openly.
Radiographic review used a standardised zone-based scoring sheet with two independent assessors.
Innovation / discovery
A lightweight, surgeon-maintained registry with mandatory PROM capture at discharge proved sustainable without dedicated research staff.
Surgical / procedural method
Consecutive series, standard ERAS pathway, PROMs at baseline, 6 months and 2 years, radiographs reviewed independently.
Research findings
- Early revision rates were comparable between groups in the demo dataset.
- Non-progressive radiolucencies were more frequent in one tibial design.
- PROM capture compliance exceeded 80% once digital collection was introduced.
