This compares the outcomes of hip and knee replacement surgery as measured by howRu (n=116) and EQ-5D (n=59,036), with both cohorts using the Oxford Hip and Knee scores as a common comparator. Outcome is the difference between the score prior to surgery and six months after surgery. For hip replacement, the correlation of outcome between howRu and Oxford hip score was r=0.77, for EQ-5D r=0.64. For knee replacement, the correlation of outcome between howRu and Oxford knee score was r=0.86, for EQ-5D r=0.59.
