Tibiofemoral wear in standard and non-standard squat: implication for total knee arthroplasty

Abstract: Introduction: Due to the more resilient biomaterials, problems related to wear in total knee replacements (TKRs) have decreased but not disappeared. In the design-related factors, wear is still the second most important mechanical factor that limits the lifetime of TKRs and it is also highly influenced by the local kinematics of the knee. During wear experiments, constant load and slide-roll ratio is frequently applied in tribo-tests beside other important parameters. Nevertheless, numerous studies demonstrate… Show more

“…It has been proven that abnormally high adduction implies osteoarthritis progression in the medial compartment of the knee joint [9,10], while the latter two phenomena are key-parameters in wear propagation between TKR surfaces. Based on the latest results, it was quantitatively determined that the effect of the tibiofemoral force and the slide-roll cause 65% and 15% more removed volume on TKR surfaces respectively [11,12]. It is worth noting that the examined TKRs showed fairly low performance ratio compared to the reference-function, since they only achieved 18-35% of the original physiological rotation described by the reference rotation [7].…”
