The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. In human females the femora converge more than in males because the pelvic bone is wider in females. In the condition genu valgum the femurs converge so much that the knees touch one another. The opposite extreme is genu varum (bow-leggedness)
Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [1] especially in the femur and tibial bones, but can also occur genetically at birth.
Some exercises to strengthen the quadriceps and hamstring muscles include leg curls, leg lifts, prone knee flexion with resistance band and knee extensions. Some stretches to help prevent injury to the posterior cruciate ligament include stretching of the hamstring muscles by extending the legs, toes pointing up, leaning forward until the ...
Commonly used exercises include isometric quadricep sets, side lying clamshells, leg dips with internal tibial rotation, etc. The idea is that because the medial side is most often stretched by the more common lateral dislocation, medial strengthening will add more stabilizing support.
Step counts and minutes are both useful ways to measure physical activity, a new study suggests. A greater number of steps per day or minutes of exercise per week are both associated with lower ...
Anti-rotation exercises refer to any exercise in which you’re resisting a rotational force, explains physical therapist Kate Bochnewetch, D.P.T., C.S.C.S., founder of the Running DPT in Buffalo ...
The knee is allowed to sag into complete extension. The opposite hand grasps the lateral portion of the leg at the level of the superior tibiofibular joint, increasing the force of internal rotation. While maintaining internal rotation, a valgus force is applied to the knee while it is slowly flexed. If the tibia's position on the femur reduces ...
Tibial nerve: Actions: Medially rotates tibia on the femur if the femur is fixed (sitting down) or laterally rotates femur on the tibia if tibia is fixed (standing up), unlocks the knee to allow flexion (bending), helps to prevent the forward dislocation of the femur while crouching: Identifiers; Latin: musculus popliteus, poplit=ham (pit) of ...
