- Rolling and Gliding Mechanism:
- bones forming joint are femur, tibia, & patella;
- two femurs converge toward the knee and each tibia is nearly vertical, femur & tibia meet angle of some 5-12 deg;
- greater angle results in genu valgum;
- lesser angle results in genu varum;
- femur ends in two rounded condyles joined anteriorly to from patellar articular surface and separated posteriorly by a deep
- condyles are almost in line w/ front of shaft, but they project backward well beyond shaft, as in letter J, circumstance of
significance in movement of the joint;
- medial condyle is larger, more curved, & projects further than lateral condyle, accounting for angle between femur & tibia;
- sides of condyles are roughened and project somewhat as medial and lateral epicondyles;
- tibial plateua:
- on its expanded upper end, tibia has 2 slightly concave condyles separated by an intercondylar eminence and the sloping areas
in front and behind it;
- low elevation, tibial tuberosity, for insertion of quadriceps, is situated at the junction of anterior border of shaft with expanded
upper end of the tibia;
