1 Previous studies have shown a 3-year mortality of 24.7% in CRT recipients vs. 38.1% in the control population. 2 Mortality in CRT has been associated with several pre-implant risk factors that predict mortality.
However, there are still problems like the sizing of implants, risk of disease transmission, and limited availability [ 8, 9].
As compared to the trochlea, the posterior aspect of the lateral column is non-articular and allows for posterior placement of implant without risk of injury to the cartilage or risk of impingement with flexion and extension.
The comprehensive Scandinavian Registers have reported on prosthesis revision rates across entire countries, providing our best estimates of implant revision risk in large, national populations.
For patients having received this particular implant combination risk factors were identified which were associated with the occurence of implant failure.
"Because of this, and because removing these implants carries risk in itself, we are not advising routine removal of these implants".
Implant overhang risks adverse soft-tissue interaction while uncovered cut bone surfaces (underhang) risks increased postoperative bleeding or development of heterotopic bone.
Clinical and radiographic follow-up showed all components to be stable, no implants at risk of loosening, no observable osteolysis, and no observed change in bone density.
In comparison to permanent implants the risk of inflammatory reactions is significantly reduced and no foreign material is left in the body using degradable materials.
It has also been used to determine whether implants are ready for the final restoration [35] or ready to be loaded [33] and to identify the implants at "risk" [36].
Among both cemented and uncemented implants, revision risk was lower in older than in younger patients.
