The aim of the study is to evaluate the myofascial chain lines in addition to the general evaluation parameters in patients with patellofemoral pain syndrome (PFPS) and to determine whether deviations from normal in the myofascial structure have an effect on the development of PFPS. There will be two groups in this study. One of the groups will consist of 28 patients aged between 25-50 years. The other group will consist of 28 healthy individuals between the ages of 25-50 years. Postural problems that can be seen in the superficial anterior myofascial chain line will be evaluated. These problems: forward head, q-angle, genu varum, genu valgum, foot postural problems (pes planus, pes kavus vb.) and pelvic tilt. In addition to all these assessments, knee pain and the biomechanical properties of the anterior myofascial tissue will be evaluated.

Primary | Knee pain | Visual Analogue Scale (VAS) will be used in the assessment of pain severity. VAS expresses pain severity between a score of 0 (no pain) and 10 (unbearably severe pain). The subject is asked to mark the score that best reflects the severity of knee pain he/she feels. | baseline | |
Primary | Forward head | The end point of the superficial anterior myofascial chain considered in the study is the mastoid process. And to this point attach muscles such as the sternocleidomastoid (SCM) that affect head and neck movements and position. In case of shortness of these muscles, forward tilt of the head may occur. The craniovertebral angle will be considered in determining the forward tilt of the head. In this study, markers will be placed on the mastoid process and C7 spinous process to determine the craniovertebral angle. Photographs of the individual will be taken from the front and side, and then the craniovertebral angle will be calculated using the Tracker 4.11.0 software on these photos. FHP is characterized as pathologic when the craniovertebral angle (CVA) is =50°. | baseline | |
Primary | Q-Angle | For the Q angle, the angle between a straight line from the SIAS to the center of the patella and the line from the center of the patella to the center of the tuberositas tibia will be measured with a goniometer. While the Q angle can be between 6° and 27°, its approximate average value is 15°. Increasing or decreasing the Q angle increases the pressure in the lateral and medial compartments of the patellofemoral joint.
4- Genu varum |
baseline | |
Primary | Genu varum | The individual in the standing position is asked to unite the lower extremities while maintaining 0° extension of the knees. The distance between the medial condyles is measured as the medial malleolar are in contact. If the distance is more than 1 cm, it indicates the genu varum. | baseline | |
Primary | genu valgum | The individual in the standing position is asked to unite the lower extremities while maintaining 0° extension of the knees. The distance between the medial malleolar is measured as the medial condyles are in contact. If the distance is more than 1 cm, it indicates the genu valgum. | baseline | |
Primary | pes planus | Pes Planus will be evaluated with navicular drop test. The distance between the navicular bone and the ground is measured while the individual sits on the chair with the hip-knee joint in 90º flexion and the subtalar joint in neutral position. Then, the distance between the navicular bone and the ground is measured again while the individual is standing in a position with equal weight on both extremities. The difference between the two measurements is recorded. 10 mm or more difference is considered pes planus. | baseline | |
Primary | foot posture | Foot posture will be evaluated using the Foot posture index, a six item foot posture assessment tool, where each item is scored between -2 and +2 to give a sum total between -12 (highly supinated) and +12 (highly pronated). Items include: talar head palpation, curves above and below the lateral malleoli, calcaneal angle, talonavicular bulge, medial longitudinal arch, and forefoot to rearfoot alignment. | baseline | |
Primary | pelvic tilt | The position of the pelvis will be evaluated with a digital pelvic inclinometer device to determine whether the pelvis has tilted anteriorly or posteriorly. The digital pelvic inclinometer is a valid and reliable method for the evaluation of pelvic tilt. The device consists of two calipers and the calipers are placed on the SIAS (spina illaca anterior posterior) and SIPS (spina illaca posterior superior) of the pelvis. The score on the digital display is recorded. "-" values indicate posterior pelvic tilt, "+" values indicate anterior pelvic tilt. | baseline | |
Primary | Biomechanical and viscoelastic properties of myofascial tissues | Biomechanical and viscoelastic properties of myofascial tissues will be evaluated with MyotonPro digital palpation device which is a valid and reliable. In the measurements, the Myoton probe will be placed perpendicular to the fibers of the tissue to be measured and when the probe reaches a sufficient depth, 3 repetitive mechanical stimulus (15ms, 0.40N) will be given to the tissue that has pre-compressed (0.18N). The passive tone and stiffness properties will be calculated by the device from the average of the oscillatory responses of the tissue to this mechanical stimulus. Measurements were taken 3 times from each point and the average values will be used in statistical analysis | baseline |
