Sponsor's own description
The Q angle, also known as the quadriceps angle, is defined as the angle formed between the quadriceps muscles and the patella tendon. It was first described by Brattstrom in 1964 (1). The Q angle is the angle between the line extending from the anterior superior of the spina iliaca to the midpoint of the patella and the line extending from the midpoint of the patella to the tuberositas tibia (2). Normally, this angle is between 8-14 degrees in men and 11-20 degrees in women. Any alignment change that increases the Q angle is thought to increase the lateral force on the patella. The Q angle is generally evaluated in static postures in the literature. The Q angle value varies according to the patient's gender, the contractility of the quadriceps, and the patient's posture (standing or supine) (3). Q angle was evaluated in a static posture with a standard goniometer or computerized biophotogrammetry (4) Q angle changes with the forces applied by dynamic structures. It is insufficient to evaluate only in a static posture. Therefore, the aim of this study is to examine the effect of dynamic structures on the Q angle using 2D gait analysis (video) and to detect the early signs of deviation of changes in the q angle.
