Abstract

This prospective study evaluates 100 consecutive Harris-Galante Porous (Zimmer, Warsaw, IN) noncemented femoral prostheses 4 to 8 years after surgery. Two femoral components were revised for aseptic loosening. The mean Harris hip score was 56 before surgery and 92 at final follow-up evaluation, with moderate thigh pain seen in 6%. Ingrowth was classified as bony (89%), stable fibrous (8%), and unstable (3%). A pedestal formed in 18%, measurable subsidence occurred in 22%, and endosteal erosion occurred in 12%. Patients with pedestal formation had a higher incidence of unstable growth pattern (P < .05). Patients with bony ingrowth had a lower mean subsidence (0.38 mm) than those with fibrous stable ingrowth (3 mm) and unstable ingrowth (7.5 mm) (P < .05). Thigh pain correlated with the type of ingrowth, and endosteal erosion with the linear polyethylene wear. Survival analysis was 97.5% at 8 years.

      Many reports have supported excellent long-term results of the Harris-Galante I acetabular cup [2,3]. However, because of relatively poor short-term and midterm results of the Harris-Galante stem [4,5], few long-term studies regarding the stem side have been published [6,7]. This study is a long-term follow-up study of the Harris-Galante THA that focused on the cup side and the stem side.

      The Kaplan-Meier survivorship probability with femoral revision as the end point was 90% (95% CI, 80.8%-95.2%) in our cohort. Petersilge et al [13] in their prospective study, which includes a subset of patients also in this study, documented a postoperative mean HHS of 92 at 5.8 years in a population of cementless HGP hip arthroplasties. Archibeck et al [2] also found a high postoperative HHS with second-generation cementless hips, reporting a mean of 94 at 10 years.
