Abstract:
This study investigates knee joint biomechanics during lunges under varying tibial angles and external loads using musculoskeletal modeling and finite element analysis. Twenty-six healthy young men performed lunges at tibial inclination angles relative to the ground (60° and 90°) under two external load conditions. Knee joint moment was higher at 60° than at 90°. External load affected knee stiffness, with lower rotational stiffness under the 98 N external-load condition. Under the 90° tibial-angle condition with external load, peak stress and displacement were concentrated in the posterior horn of the meniscus. These findings provide biomechanical support for lunge-based training and rehabilitation.

The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
