Total hip arthroplasty (THA) has become well-known as being one of the most successful procedures with much long-term positive clinical results. However, revision surgeries are still required. The four most common failure modes for THAs, “reasons for revision”, are loosening, dislocation or instability, fracture, and infection. The goal of a hip arthroplasty register is to gather information on patients that undergo a total hip arthroplasty and factors pertaining to their surgery which may affect their outcome for future years such as the reason for revision. Analysis of this data can help with the allocation of healthcare funds and the efficacy of on both the clinical and device side. The objective of this research was to compile the national registries for hip replacements into a global registry, comparing the data from different countries and statistically analyzing the reasons for revision. Global trends of revision surgeries were identified and projected. A total of 37 national joint registries were identified, of which 15 contained data on the failure modes. The results showed that the reason for revision had a significant effect on the percentage of revisions with loosening leading to a significantly greater percentage of revisions than any other reason. For the countries with the most complete data, it was found that the country did not have any significant effect on the percentage of revision. Additionally, when analyzing various countries over a 5-6-year period, it was found that the year did not significantly affect the percentage of revisions.
