Lateral condyle of tibia

The lateral condyle of tibia forms the outer portion of the expanded upper part of the tibia. It’s superior articular surface is nearly rounded in shape. The central portion of the lateral condyle’s articular surface is concave and directly articulates with the lateral condyle of the femur. The outer margin is covered by a C-shaped cartilaginous rim known as the lateral meniscus, which acts as a shock absorber and provides stability to the knee joint. On the medial side of the superior articular surface, there is a prominent bony tubercle that flanks the lateral extent of the intercondylar eminence.

The upper border of both the lateral and medial condyles serves as an attachment site for the capsular ligament of the knee joint. Additionally, the margins of the fibular articular facet provide attachment for the capsular ligament of the superior tibiofibular joint. Anteriorly, the lateral condyle of tibia attaches to the iliotibial tract, while posteriorly, the groove on the back of the lateral condyle of tibia accommodates the tendon of the popliteus muscle.
