Femur Femur The femur (, pl. "femurs" or "femora" ) or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and kneecap forming the knee joint. By most measures the femur is the strongest bone in the body. The femur is also the longest bone in the human body. The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate
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
