The results of TAA are promising, but the revision rate is higher than for total hip or knee arthroplasty. TAA outcome measurement by means of registers has several specific requirements necessitating additional documentation beyond the basic data set. For methodological reasons the evaluation of results is more complex than for hip or knee arthroplasty. It will therefore be essential to standardise data collection and evaluation and develop a methodology addressing the specific needs of TAA.

The few studies published in French include only a limited number of cases, but their follow-up is long and the revision rate consistent with register data. There is no indication of any type of bias in French scientific publications relative to the reproducibility of THA results.
