Patellar component design influences size selection and coverage

These findings characterized how implant design influenced size selection and coverage in a population of patients. The ability to “upsize” with oval dome components led to increases in bony coverage and better replication of the median ridge compared to round components. Quantifying the interactions between implant design, sizing and coverage for a current implant system in a population of patients supports surgical decision-making and informs the design of future implants.
