Tibiofemoral Contact Area-Determination and Implications

In vivo tibiofemoral cartilage‐to‐cartilage contact area of females with medial osteoarthritis under acute loading using MRI

“…Similar to results of this study, it has been reported that the medial compartment has larger tibiofemoral contact area than the lateral compartment. Kettelkamp and Jacobs (27) reported that the medial tibiofemoral contact area of cadaver knees under clamped compression averaged 1.64 times that of the lateral tibiofemoral contact area. Fukubayashi and Kurosawa (9) reported the average medial-to-lateral tibiofemoral contact area ratio of 1.26 under 500N of compression and Morimoto et al (11) reported an average ratio of %1.30 under 1000N of compression.…”

“…Understanding contact area changes may help elucidate the relationship between disease, mechanics, and compensatory effects and may provide a mechanism to monitor treatment effects. Tibiofemoral contact mechanics or contact areas under compressive loading have been studied using cadaver specimens with various experimental conditions (7,(9)(10)(11). However, it is unknown how much human in vivo tibiofemoral cartilage-tocartilage contact area changes when the knee joint is exposed to acute loading of similar magnitude to physiologic conditions.…”

Tibiofemoral Alignment: Contributing Factors to Noncontact Anterior Cruciate Ligament Injury

“…The area of contact between the articular surfaces on the medial side of the joint is greater than the area of contact on the lateral side of the joint 33 . In addition, the lateral tibial plateau is more convex than the concave medial tibial plateau.…”

The Contact Area and Pressure Distribution Pattern of the Knee:A Study of Normal and Osteoarthrotic Knee Joints

“…Kettelkamp & Jacobs (1972) demonstrated the tibiofemoral contact area under a 30-80N load by roentgenographic methods. The contact area after the removal of the menisci was 468 mm2 on the medial and 297 mm2 on the lateral side.…”
