The published results of the clinical studies involving many of the arthroplasty implants, especially implants developed in the United States, were highly influenced by reports from the center that developed the implant.
This often had a substantial effect on the reproducibility of the outcome data.
There appeared to be relevant differences between the medical research systems in Europe and the United States that also affected the reproducibility and applicability of the results for the average surgeon.
Registry data can contribute substantial added value to an informed discussion of arthroplasty outcomes.
