About this trial
The aim of this study is to examine in detail the ultrasonographic characteristics of the vastus medialis obliquus and vastus medialis longus muscles in individuals with patellofemoral pain syndrome and to compare these findings with those of healthy individuals. It is anticipated that the results obtained will contribute to a better understanding of the muscle-based mechanisms of PFAS and provide a scientific basis for the development of muscle-specific assessment and intervention strategies in physical therapy and rehabilitation practices.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Between the ages of 18 and 65
Have had localized pain in the front of the knee for at least the past 3 months
Experience pain during activities that require stair climbing, squatting, prolonged sitting, or knee flexion
Have been diagnosed with patellofemoral pain syndrome based on clinical evaluation
Disqualifiers
History of previous surgery on the knee joint
History of significant trauma to the knee region within the last 6 months
Diagnosis of meniscus, ligament injuries, knee osteoarthritis, or inflammatory rheumatic disease
Neurological diseases or systemic diseases affecting the musculoskeletal system
Trial population
The study will include individuals aged 18-65 who have been diagnosed with patellofemoral pain syndrome, as well as healthy volunteers with similar characteristics in terms of age and gender. The study group will consist of individuals who have applied to a physical therapy and rehabilitation clinic or who have been referred to relevant units. The control group will be selected from healthy volunteers who do not have any knee pain or lower extremity musculoskeletal problems.

Ultrasonographic Measurement
A B-mode ultrasound device with a high-frequency (7-12 MHz) linear probe will be used to evaluate muscle architecture. Ultrasound is a reliable, reproducible, and non-invasive imaging method for assessing the morphological characteristics of muscle tissue. Ultrasonographic evaluations will be performed by an experienced researcher in musculoskeletal ultrasonography, in a quiet and standard environment. A high-frequency (7-12 MHz) linear probe will be used during measurements. Participants will be placed on the evaluation table in a supine position, with the knee joint fully extended and relaxed. Before measurements, anatomical reference points will be determined using a tape measure, and temporary markings will be made on the skin. Vastus Medialis Obliquus (VMO): VMO muscle thickness measurement will be performed in the region where the oblique orientation of the muscle fibers is prominent, using the upper-medial edge of the patella as a reference. The measurement point will be determ
