How to tell right and left tibia? Place the tibia on the anterior surface of your leg with the tibial tuberosity facing anteriorly (not touching your leg). What side is the medial malleolus on? It should be medial, towards the midline of the body.
FIBULA Lateral malleolus Head Lateral malleolus Head
How to tell R from L fibula Place the fibula on the table with the smooth side of the lateral malleolus facing down. Pretend to trace the malleolus. Notice that one side (posterior) is straight and the other side (anterior) is curved. Place the smooth surface of the lateral malleolus against your sock at your own lateral malleolus. The curved edge should face anteriorly, not posteriorly.
Patella Lateral articular facet Medial articular facet The Lateral facet is larger. If you place the patella on your desk, it will always fall onto the lateral articular facet.
Turning An Ankle Into A 'Knee' Patient was a five-year-old girl with Ewing's sarcoma, a cancerous tumor, behind her left knee. Surgeons at The Children's Hospital of Philadelphia used a limb-sparing technique called rotationplasty to remove the diseased portion of bone, turn the shortened portion of the leg bone in a half-circle and reattach it, with the ankle joint functioning as a knee. With a prosthetic attached to the mobile joint, the child, now 13, enjoys gymnastics and cheerleading.
