Retrospective review of 76 revision TKAs performed at Hospital for Special Surgery (1980–1988) evaluating a hybrid fixation technique: cemented metaphyseal surfaces combined with press-fit uncemented fluted diaphyseal stems, with modular metal wedges/augments for bone defects. Outcomes assessed by HSS knee score and survivorship analysis at mean 3.5-year follow-up.
When performing revision TKA, this technique — cement only on metaphyseal cut surfaces with uncemented fluted diaphyseal stems.
Provides reliable fixation (83% 8-year survival) while preserving diaphyseal bone stock for future revision; don't be alarmed by radiopaque lines around the uncemented rods on follow-up imaging, as they carry no association with clinical failure.
