Background:
The 'Tritanium' (Stryker, New Jersey, USA) highly porous acetabular cup is a new implant used in revision hip arthroplasty.
Aim:
To determine the early results of this device.
Methods:
A prospective study of 43 acetabular component revisions performed using the implant between March 2007 and February 2008 was undertaken. All procedures were performed at a single centre with standard approach and follow up.
Results:
The mean age of patients at surgery was 66 years. Mean follow up was 18.2 months. AAOS classification revealed 17% Type 1, 49% Type 2, 24% Type 3 and 5% Type 4 defects at surgery. 5% had no bone defect. Bone graft was used to in 73% of patients. Mean Harris Hip Score improved from 68 pre-operatively to 86 at the last follow-up. Cup integration was seen in 95% of patients by 6 weeks. One patient with pelvic discontinuity had symptomatic aseptic loosening which was revised.
Conclusion:
The 'Tritanium'acetabular cup has been successful in achieving rapid osseointegration with few complications. The management of pelvic discontinuity continues to be a challenge.
