Influence of Geometry and Extent of Coating on Survival of Cementless Distal-Locking Revision Stems at 7 to 18 Years.

Background: We aimed to compare the long-term clinical outcomes, complications, and survival of 2 revision stems with different geometries, extents of coating, and distal-locking mechanisms.

Methods: We retrospectively compared outcomes at a minimum of 7 years following revision THA using 2 proximally coated distal-locking stems: 98 Ultime first-generation (G1) and 116 Linea second-generation (G2) stems. Ten-year Kaplan-Meier survival was assessed considering stem re-revision for any reason and for aseptic reasons.

Bilateral One-Stage Revision of Infected Total Hip Arthroplasties: Report of Two Cases and Management of Antibiotic Therapy.

Recommendations for the management of chronic and bilateral total hip arthroplasty (THA) infection are lacking. However, this type of infection involves medical problems concerning the management of the antibiotic therapy. We report two cases of such infections operated as one-stage revision.
