Posterior cruciate ligament the tibia. The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement. It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface. Although each PCL is a unified unit, they are described as separate anterolateral and posteromedial sections based off where each section's attachment site and function. During knee joint movement, the PCL rotates such that the anterolateral section stretches in
Tuberosity of the tibia necessary to allow for normal function. Tenderness in the tibial tuberosity can arise from Osgood-Schlatter’s syndrome or deep infrapatellar bursitis. A bony prominence on the tibial tuberosity can be the result of ongoing Osgood-Schlatter’s irritation in an adolescent with open growth plates, or what remains of Osgood-Schlatter’s in adults. Tuberosity of the tibia The tuberosity of the tibia or tibial tuberosity or tibial tubercle is a large oblong elevation on the proximal, anterior aspect of the tibia, just below where the anterior surfaces of the lateral and medial tibial condyles end. It gives attachment to the patellar ligament, which attaches
