TL;DR
Cementless primary femoral stems are a reliable option for rTHA in patients with preserved metaphyseal bone, demonstrating low aseptic loosening rates and favorable functional outcomes at mid- to long-term follow-up.
BACKGROUND The influence of collar design on femoral stem survival in total hip arthroplasty (THA) remains debated despite its potential biomechanical advantages. This registry analysis investigated whether collared stems demonstrate superior survival compared to non-collared designs in primary THA. METHODS A retrosp...
Bone loss remains one of the challenges in revision total knee arthroplasty (rTKA). Trabecular Metal (TM) metaphyseal cones have been increasingly used to achieve stable fixation. While short- and mid-term results are promising, long-term outcomes remain poorly documented. The objective of this study was to evaluat...
This review evaluates the clinical indications, surgical rationale, and outcomes of six targeted component-retention strategies in revision total hip arthroplasty (THA) designed to reduce operative morbidity and preserve host bone stock. This is a narrative review. A structured but non-systematic search of PubMed/MEDLI...
The findings support the idea that when components are well-fixed and compatible, isolated component revision may serve as a less morbid option for rTKA and further studies are required to corroborate these findings.
Background: Porous tantalum implantation is a head-preserving alternative to core decompression in osteonecrosis of the femoral head. Reporting has declined in North America and Europe while continuing elsewhere; outcomes are discordant. Prior syntheses are dated and treated the two endpoints as interchangeable. Method...
