Porous tantalum cementless acetabular components show stable fixation, positive outcomes and “excellent survivorship” at 10- to 15-year follow-up for revision hip arthroplasty, according to data presented at the Virtual EFORT Congress.

Ibrahim and colleagues retrospectively reviewed 102 patients who had received porous tantalum cups during revision THA from 2003 to 2009. Mean age was 80 years. The primary outcome measure was revision of the acetabular component at a minimum of 7 years of follow-up. Secondary outcome measures included radiological assessment and patient-reported outcome measures, such as preoperative and postoperative SF 12 and WOMAC scores.

After adjusting for patients with a minimum 10-year follow-up, Ibrahim and colleagues found implant survivorship was 95.3%. Total WOMAC scores improved from 46.8 preoperatively to 64.4 postoperatively. Likewise, SF 12 scores improved from 29 preoperatively to 32 postoperatively.

Radiographic results showed a well-fixed implant with no loosening or migration. Few complications were reported, with four patients requiring revision, according to Ibrahim.

“Compared with the available literature, we are still the largest cohort available with excellent survivorship of 95.3%,” he said.

While mortality unrelated to surgery and loss to follow-up are potential limitations, Ibrahim said porous tantalum implants provide “excellent clinical and radiological outcomes.”
