Revision total hip arthroplasty using third-generation cementing technique

A total of 83 consecutive first-revision total hip arthroplasties were perf ormed in 83 patients using pressurized vacuum-mixed cement, a third-generat ion cementing technique. At a median follow-up of 3.6 years (range, 1.5-6.3 years), the overall failure rates (radiographic loosening, re-revision, or both) were 39% for the femoral components and 30% for the acetabular compo nents. With definite radiographic loosening as an endpoint, the cement-bone interface achieved was the only significant factor to predict stem durabil ity, with an adjusted odds ratio of 1.8 (95% confidence interval, 1.1-3.0). On the acetabular side, bone stock was the only significant factor, with a n adjusted odds ratio of 5.3 (95% confidence interval, 4.0-27.7). In this r etrospective cohort study, femoral cement pressurization per se did not app ear to improve the results over those of other studies using second-generat ion techniques.
