title: Cementless primary total hip arthroplasty with a tapered, proximally porous-coated titanium prosthesis: a 4- to 8-year retrospective review.
abstract: A consecutive series of 100 primary total hip arthroplasties were performed at a single institution on 87 patients using a cementless collared titanium press-fit stem. Of patients, 87% received a hemispheric porous-coated cup, and 13% received a nonmodular titanium fibermesh press-fit cup. Ten hips were excluded from the longer-term evaluation: 6 were lost to follow-up, and 4 patients were deceased. Ninety hips, with an average follow-up of 81 +/- 12 months, were retrospectively reviewed. The average postoperative hip score was 94, compared with an average preoperative hip score of 42. No postoperative infections were observed, but there were 2 cases of postoperative dislocation (2%) and 1 case of thigh pain (1%) at last follow-up. There were 2 revisions, both for cup failures. There were no femoral component loosenings or revisions. There was no evidence of stem subsidence or instability. These midterm results are encouraging with this stem design.
