A randomized controlled trial was performed to assess the effect of a rim cutter device on cement mantles in modern elective total hip arthroplasty using a flanged acetabular component. Forty patients were randomized to a rim cutter (21) or control (19) group. A statistically significant improvement in cement penetration was demonstrated in zone 1 (10.1 vs 8.6 mm, P = .023), and in cement mantle thickness in zones 2 and 3 (7.8 and 6.7 mm vs 5.7 and 5.4 mm [P < .001 and P = .017]), with a reduced incidence of bottoming out of the socket (1/21 vs 8/19 [P = .007]). Cement mantle thicknesses greater than 8 mm were achieved more consistently in the rim cutter group (30% vs 2%). This technique improves cement penetration and mantle thickness in a reliable manner.
