Description
Summary:The cost of primary total hip replacement products approaches 65% of the total reimbursement. Durability of total hip replacement resides with the acetabular component. This systematic review and meta-analysis determined if the outcomes of durability, function, and adverse events associated with cemented all-polyethylene acetabular components was similar to other acetabular designs, holding other variables constant. Randomized controlled trials only were evaluated. Two independent reviewers collected the data from 6 randomized controlled trials. Appropriate statistical analysis was performed. There was no statistical difference in regard to the outcomes at various time points (≤3, 4-8, and ≥10 years) in the 907 implants evaluated. There does, however, appear to be a trend toward abject failure with cemented all-polyethylene acetabular component implants consistent with findings of increased radiolucencies more than 10 years out. The issue of increased radiolucencies over time and failure with these types of implants bears closer scrutiny.
