Dataset description

This dataset captures the physical changes in natural hip joint specimens across varying levels of acetabular clearance, ranging from natural tissue to extra-large clearance configurations. It features comprehensive metadata logs (SpecimensLog.csv and Degraded-Pre-test Ratio.csv) alongside an organised repository of sequential photographic observations taken at every hour for eight hours of testing. The collection is designed to support the analysis of material degradation, and component pairing, under controlled experimental conditions.
