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...
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...

Summary
This summary is machine-generated.

Fatigue significantly reduces knee control in female soccer players during cutting tasks. This diminished control, particularly at initial contact, highlights the need for interventions to mitigate fatigue

Area of Science:

  • Sports Biomechanics
  • Motor Control
  • Female Athlete Health

Background:

  • Fatigue is a common factor in sports injuries.
  • Understanding biomechanical changes during fatigue is crucial for injury prevention.
  • Female athletes may exhibit different responses to fatigue compared to males.

Purpose of the Study:

  • To investigate the impact of a sequential fatigue protocol on lower extremity biomechanics.
  • To analyze biomechanical alterations during a crossover cutting task in female soccer players.
  • To identify specific kinematic changes associated with fatigue in this population.

Main Methods:

  • Eighteen female collegiate soccer players performed a fatigue protocol and crossover cutting trials.
  • Lower extremity biomechanics were captured using 3D motion analysis and force plates.
  • Repeated-measures ANOVAs compared biomechanics at pre-fatigue, 50% fatigue, and 100% fatigue stages.

Main Results:

  • Knee flexion at initial contact significantly decreased with increasing fatigue (pre: -32°, 50%: -29°, 100%: -22°).
  • Knee adduction at initial contact was significantly higher pre-fatigue and at 50% fatigue compared to 100% fatigue (pre: 9°, 50%: 8°, 100%: 6°).
  • Fatigue led to diminished knee control at initial contact.

Conclusions:

  • Sequential fatigue significantly alters sagittal and frontal plane knee kinematics in female soccer players.
  • Diminished knee control at initial contact suggests increased injury risk.
  • Interventions should focus on maintaining frontal plane alignment and increasing knee flexion during fatigue.
