Table 2.
Variable | Total cementation with fully cemented stem | Hybrid cementation with press fit stem |
---|---|---|
Advantage | Easy to implant | Potential for bone stock preservation |
Better initial stability | Less stress shielding | |
Potential benefit of intramedullary elution of antibiotics | Optimizing mechanical alignment by diaphyseal referencing | |
More variability in component positioning and sizing | Easy to remove | |
Useful especially in diaphyseal bowing | Applicable in patients with previous DFO or HTO | |
Disadvantage | Difficult to remove | Potential for end-of-stem pain |
Decreased references for proper alignment | Potential forcing of component into suboptimal position without offset stem | |
Risk of periprosthetic fractures with canal preparation |
DFO: distal femoral osteotomy, HTO: high tibial osteotomy.
