The authors of that study commented: "In the absence of rigorous scientific clarification, information on biomaterials is frequently a source of confusion and misleading generalisations worrying to orthopaedic surgeons."

Indeed, from their inception eighteen years ago, the performance of zirconia ceramic balls (Fig. 1) has been both confusing and controversial. Given the diversity of clinical results, it may well be true that not all zirconia balls were created equal. Thus, the above quotation appears as salient today as it was in 1999. A more recent French study reinforced this opinion: Hamadouche et al. noted that they could find only two studies that demonstrated favorable clinical results with the use of zirconia balls2.
