Patellar complications frequently limit the success of total knee arthroplasty. In addition to
the musculoskeletal forces themselves, patellar tendon elastic properties are essential for …

Background: The complexity of the spatial dynamic flexion axis (DFA) of the elbow joint
makes the elbow prosthesis design and humeral component alignment challenging. This …

Background The ability of the quadriceps muscles to extend the knee depends on the
moment arm of the knee-extensor mechanism, which is described by the moment arm of the …

Muscle moment arm is a property that associates muscle force with joint moment and is
crucial to biomechanical analysis. In musculoskeletal simulations, the accuracy of moment …

Background: For total knee arthroplasty (TKA), the optimal rotational position of the femoral
component is felt to be critically important. The current knee joint kinematics measurement …

Mechanical loading of the knee joint is connected to pathologies involving structural
degeneration of the knee, including knee osteoarthritis. Information of knee joint loading …
