Area of Science:

  • Orthopedics and Biomechanics
  • Anatomy

Background:

  • Understanding normal lower extremity alignment is crucial for diagnosing and treating musculoskeletal conditions.
  • Existing data on femorotibial alignment, joint line orientation, and lower extremity anatomy requires comprehensive summarization.

Purpose of the Study:

  • To summarize the range and variation of femorotibial alignment.
  • To analyze the horizontal orientation of the hip, knee, and ankle joint lines.
  • To document other relevant anatomic factors of the lower extremity in normal populations.

Main Methods:

  • Two-dimensional frontal plane analysis was employed.
  • Data was collected from normal population groups.
  • Participants were evenly divided according to gender and age.
