“…Trauma, a high level of activity, and obesity may increase the risk of breakage by increasing the load across the joint surface [7,8]. Other factors to take into account are mechanical properties of the ceramics, implant design, and surgical techniques in implantation of the prosthesis [8].…”

“…The initial studies reported instances of bearing chipping and fractures [10,20,24]. Improvements in ceramic manufacturing, namely hot isostatic pressing, resulted in decreased grain size and yielded a noticeable decrease in the rate of material fracture and chipping [24].…”

Background Alternative bearing materials in THA have been developed to reduce the incidence of osteolysis. Alumina-on-alumina bearings exhibit extremely low wear rates in vitro, but concerns exist regarding component impingement with the potential for dislocation and the occurrence of noise. Questions/purposes We determined generation of squeaking and the relationship between squeaking and component position. Methods We prospectively entered 436 alumina-on-alumina, cementless, primary THAs in 364 patients into our institutional database. All procedures were performed with the same surgical technique and the same implant. We obtained Harris Hip scores and a noise questionnaire and assessed radiographic component position and loosening. We determined the difference in abduction angle between squeakers and nonsqueakers. Minimum followup was 2 years (average, 3.5 years; range, 2.0-6.2 years).

In the 1980s, zirconia was introduced for THA with the expectation of lower polyethylene wear and better clinical results. However, several studies have reported poor survivorship of zirconia-polyethylene THA. We performed a systematic review and meta-analysis of zirconiapolyethylene THA to confirm or refute the theoretical advantages of this combination. Of 163 studies identified by a comprehensive search, seven met our selection criteria. These involved 769 hips of 586 patients with a mean age of 56.8 years and a minimum followup of 60 months (mean, 89.2 months; range, 60-155 months). The consolidated revision rate of zirconia-polyethylene THA at 89.2 months was higher than that of nonzirconia-polyethylene THA by 5% (risk difference, 0.05; 95% confidence interval, 0.02-0.08). Subgroup meta-analysis suggested THAs with zirconia heads from Ceraver had more revision surgery than nonzirconia heads (risk difference, 0.08; 95% confidence interval, 0.03-0.14), whereas zirconia heads from DePuy did not (risk difference, 0.02; 95% confidence interval, À0.01-0.06). The meta-analysis for annual linear polyethylene wear (which did not involve zirconia heads from Ceraver because of insufficient descriptions) showed no difference between zirconia and control groups. Collectively, THAs with high-quality zirconia heads appear to have prosthesis survivorship and polyethylene wear equivalent to those of THAs with traditional materials, but differing quality among zirconia heads could lead to poor survivorship of prostheses. Level of Evidence: Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
