Joint registries: what can we learn in 2016?

Abstract

Aims: To demonstrate, with concrete examples, the value of in-depth exploration and comparison of data published in National Joint Arthroplasty registry reports.

Patients and methods: The author reviewed published current reports of National Joint Arthroplasty registries for findings of current significance to current orthopaedic practice.

Results: A total of six observations that demonstrate actionable or unexpected findings from joint registries are described. These include: one third to one half of all arthroplasty failures in the first decade occur in the first one to two years; infection rates after arthroplasty have not declined in the last three decades; infection after TKA is more common in men than women; outcomes of TKA are more variable in young compared with older patients; new technologies (uncemented implants and crosslinked polyethylene) have improved results of THA and a real-time shift in use of ceramic femoral heads is occurring in THA.

Conclusion: These six observations may be used to better understand current practice, stimulate practice improvements or suggest topics for further study. Cite this article: Bone Joint J 2017;99-B(1 Supple A):3-7.
