For this reason, implants have been shown to last between ten and fifteen years in the human body.
An exciting material to enter orthopaedics in recent years is OXINIUM Oxidized Zirconium.
Because it can achieve this remarkable reduction in implant wear without sacrificing strength as actual ceramic components do, oxidized zirconium implants have the potential to last significantly longer.
Knee replacement surgery typically takes between one and two hours to complete.
This roughened surface, when rubbing against the plastic component up to two million times per year, can more quickly wear out your implant.
When that happens, you will have to undergo surgery to replace the plastic piece, the femoral component, and possibly even the tibial component.
One remarkable breakthrough has been the creation of the JOURNEY II BCS knee, a second-generation knee replacement that combines the stability and natural motion of the human knee with new low-friction materials that may extend the life of the implant.
However,even this high-quality industry standard has its shortcomings.
Over time, this metal surface can become roughened by bone and bone cement particles trapped between the femoral component and the plastic tibial insert.
With these traditional knee replacement designs, the muscles and ligaments around your new joint have to work harder because the implant's slightly unnatural shapes and resulting motion make these soft tissues move in unfamiliar, stressful ways.
This leads to joint pain, muscle fatigue and the unnatural feeling patients experience while walking or bending in the months after their procedure.
