Early tibial loosening in the Attune total knee arthroplasty system: a retrieval analysis of clinical, demographic, and implant-related factors
Aseptic tibial loosening in the Attune TKA system is significantly associated with poor cement adhesion, while the redesigned Attune S+ baseplate demonstrated improved cement coverage. No adverse polyethylene degradation was observed. These findings highlight the role of implant design and cement adhesion in early failure and underscore the value of retrieval analysis for improving TKA outcomes.
