title: The fate of cementless jumbo cups in revision hip arthroplasty.
abstract: We report 5-year minimum results of cementless over-sized cups used in revision hip arthroplasty, with significant associated bone defects. Forty-three porous-coated jumbo cups were used to treat acetabular defects in revision hip arthroplasty in 42 patients with a mean age of 63 (range, 25-86). Morsellized allograft only was used in 27 hips, and bulk allograft was used in 8 cases. Two patients were lost to follow-up, and 5 died after a mean 7 years' follow-up, with retention of their prostheses. In the remaining 36 cases, the mean follow-up was 10 years (range, 6-14 years). Two acetabular components were revised for aseptic loosening and graft resorption. Two cases were complicated by dislocation. A satisfactory 92% Kaplan Meier shell survival rate was seen at 14 years.
