Transcatheter mitral valve replacement versus redo surgery for mitral prosthesis failure: A systematic review and meta-analysis [PDF]
Frontiers in Cardiovascular Medicine, 2023 BackgroundTranscatheter mitral valve replacement (TMVR) has emerged as an alternative to redo surgery. TMVR compared with redo surgical mitral valve replacement (SMVR) in patients with mitral prosthesis failure remains limited.

Biomechanical study of screw-supported prosthesis in acetabular revision [PDF]
Bone & Joint ResearchAims: Acetabular bone defects pose a common challenge in revision total hip arthroplasty (THA). Our team has applied screw-supported prostheses to the revision of severe acetabular defects and achieved good early clinical results.

Biomechanical Evaluation of a Novel Bionic Hip Prosthesis Designed for Optimized Load Transfer and Initial Stability [PDF]
Orthopaedic SurgeryObjective In total hip arthroplasty, the femoral component design requires a trade‐off between initial stability and stress shielding. We designed the new bionic hip arthroplasty (BHA) prosthesis with compression and tension screws to mimic compression ...

Trends of mechanical consequences and modeling of a fibrous membrane around femoral hip prostheses [PDF]
, 1990 In the present study, the effects of a fibrous membrane between cement and bone in a femoral total hip replacement were investigated. The study involved the problem of modeling this fibrous membrane in finite-element analyses, and its global consequences

Prospective five-year subsidence analysis of a cementless fully hydroxyapatite-coated femoral hip arthroplasty component [PDF]
, 2013 Early subsidence >1.5 mm is considered to be a predictive factor for later aseptic loosening of the femoral component following total hip arthroplasty (THA).

Modes of failure of Trifecta aortic valve prosthesis
Interactive CardioVascular and Thoracic Surgery, 2022 Abstract OBJECTIVES Several concerns have been recently raised regarding the durability of Trifecta prostheses. Different mechanisms of early failure were reported. Our aim was to study in a large population the modes of failure of Trifecta valves.
