The common failure modalities of TKR
The common failure modalities of TKR
23. The LCS Compete unconstrained femoral component allow the use of condylar augments and steam extension
24. VVC is an acronym for:
25. The LCS Complete VVC femoral component allows the use of condylar augments and stem extensions
26. The LCS Complete VVC femoral component has the same external geometry as the LCS Complete femoral component
27. Femoral metaphyseal sleeves can be used with all femoral components
28. M.B.T. revision tibial components have the same plateau dimension as the standard M.B.T. component
29. M.B.T. revision platform accept tibial block augments
??30. M.B.T. block augments are the same shape as Sigma modular augments
3.5S103
31. Tibial sleeves can be used with block augments
??32. Tibial stem extensions can be used with M.B.T. revision components
3.5S103
33. Hinge knees are recommended for
34. The Noiles Rotating Hinge (NRH) flexes to
35. The NRH is manufactured from
36. The single curve of the femoral component sagittal profile is designed to
37. The hinge pin provides M/L and A/P stability
38. The polyethylene bumb stop limits hyper extension to
39. The NRH femoral coronal geometry is
??40. The NRH bearing does not suffer edge loading because
3.5S105
41. The grooves in NRH femoral augments are designed to
42. NRH femoral metaphyseal sleeves are manufactured from
01. The most usual cause of mechanical failure is
02. Large amounts of polyethylene debris can cuse
03. What can be the consequence of malalignment or too much constraint?
04. The early signs of prosthetic loosening are
05. Radiolucent lines are not uncommon around the tibia, even in well-fixed implants.
06. Lucent lines greater than 2mm or lines increasing in size over time indicate a potential failure
07. Compressive bone strength of the proximal tibia is greatest in the :
08. The strength of femoral metaphyseal bone is generally higher than that of the tibia
09. A Type F1 femoral defect involves minimal cancellous bone damage to
10. An F2A classificatin involves damage to both condyles
11. An F2B the classification involves damage to both condyles
12. The Type 1 tibia is characterised by
13. A Type T2A L defect is a lateral tibial defect
14. The Sigma TC3 intercondylar box dimension is identical to that of the Sigma PS component
15. The Sigma TC3 femoral component has the same external geometry as the Sigma PS component
16. The TC3 tibial bearing insert has the same bearing geometry as the Sigma PS insert
17. The height of the TC3 tibial spine is
18. Sigma femoral stems augments are manufactured from
19. Sigma femoral stem extensions are available in
??20. Sigma femoral augments can be used in combination
