Distal femoral replacement (DFR) with megaprostheses is a salvage revision total knee arthroplasty (rTKA) procedure indicated in cases with massive bone defects in the distal femur. As long as these implants achieve fixation only in the diaphysis, the high aseptic loosening rate reported in some series is probably related to a lack of rotational stability. Two patients with extensive distal femoral bone defects with preservation of the metaphyseal-diaphyseal junction underwent rTKA.

Background: The initial outcomes of transcatheter aortic valve replacement in patients with left ventricular outflow tract calcification are poor. Furthermore, balloon-expandable transcatheter aortic valve replacement is associated with an increased risk of annular rupture, and self-expandable transcatheter aortic valve replacement is associated with worse post-operative residual paravalvular leakage grades. Therefore, developing an optimal method for transcatheter aortic valve replacement for patients with left ventricular outflow tract calcification is desirable.

This article introduces a surgical technique for cross-intrinsic transfers (CIT) to correct ulnar drift in rheumatoid hands performed under wide-awake local anesthesia no tourniquet (WALANT). This approach allows real-time adjustment of tendon transfer tension and active patient participation in hand movements and deformity correction during the procedure. It can be combined with other surgeries such as prosthetic replacement arthroplasties of the MCP joints.

Background: Since the transcatheter valve-in-valve (ViV) procedure was introduced in 2007, a few cases of infective endocarditis (IE) following the ViV procedure have been reported, which can be predisposed by older age, pre-existing medical conditions, and procedural techniques. Paravalvular abscesses constitute a rare complication of IE, resulting from extending IE beyond the valve annulus, less commonly caused by species. This complication is more common in prosthetic valves, particularly bioprosthetic valves.

Department of Medical Ultrasonics, the First Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China.
Background: Transcatheter valve-in-valve replacement (TMViVR) is an alternative option for patients with bioprosthetic valve failure (BVF) who are at high surgical risk. Although infective endocarditis (IE) after transcatheter mitral valve-in-valve replacement is unusual, it is associated with significantly high mortality.
Case Presentation: An 81-year-old male patient was admitted with intermittent thoracic tightness, chest pain persisting for 3 years, and shortness of breath with nausea for 1 week.
