Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
Muscles that Move the Leg01:23

Muscles that Move the Leg

The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
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...
Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Summary
This summary is machine-generated.

Forefoot landing increases knee adduction moments, potentially straining the anterior cruciate ligament (ACL). Landing technique impacts lower extremity biomechanics differently based on the athletic task performed.

Area of Science:

  • Biomechanics
  • Sports Medicine
  • Orthopedics

Background:

  • Anterior cruciate ligament (ACL) injuries are common in athletes.
  • Injuries often occur during landing with the ankle dorsiflexed.
  • Limited research quantifies biomechanics of specific landing patterns.

Purpose of the Study:

  • Evaluate effects of two landing techniques (forefoot, rearfoot) on lower extremity biomechanics.
  • Analyze biomechanical differences during sidestep cutting and pivot tasks.

Main Methods:

  • Single-group repeated measures design.
  • Twenty NCAA Division I female soccer players participated.
  • Measured kinematic and kinetic parameters during forefoot and rearfoot landings in sidestep cutting and pivot tasks.

Main Results:

  • Forefoot landing significantly increased knee adduction moment compared to rearfoot landing for both tasks.
  • Rearfoot landing increased knee valgus angle during sidestep cutting.
  • Forefoot landing increased knee valgus angle during pivoting.

Conclusions:

  • Foot landing technique significantly influences lower extremity biomechanics.
  • Forefoot landing may increase ACL strain due to higher knee adduction moments.
  • Biomechanical demands are task-dependent, varying between landing techniques and athletic tasks.
