Brief summary
Dynamic knee valgus (DDV) is an erroneous movement pattern of the lower limb that occurs in multiple planes. It results from a combination of hip joint adduction, femoral anteversion, knee abduction and external tibial torsion .
Detailed description
Dynamic knee valgus (DDV) is an erroneous movement pattern of the lower limb that occurs in multiple planes. It results from a combination of hip joint adduction, femoral anteversion, knee abduction and external tibial torsion . DDV is also referred to as a mechanism in which the knee joint moves medially relative to the hip and foot with the centre fixed to the ground.

Eligibility
Inclusion criteria
* Age between 18-50 years. * Absence of any lower extremity pain. * Having a frontal plane projection angle of 10 and above in the descent phase of squatting on one leg. * Having active or regular physical activity. * Volunteering to participate in the study.
Exclusion criteria
* Active knee pain. * History of patellar instability. * Presence of rheumatic diseases such as osteoarthritis, rheumatoid arthritis. * History of trauma or injury causing ligament laxity in the ankle, hip or knee. * Having a neurological disease that may impair the ability to perform any lower limb movement. * Having undergone any lower extremity surgery before. * Having received physiotherapy from hip, knee and ankle in the last 6 months. * To be benefiting from another treatment during the study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Frontal Plane Projection Angle (FPPA) | 6 weeks | FPPA is measured as the angle between a line drawn from the marked point on the proximal thigh to the knee joint and another line extending from the knee joint to the ankle during maximum knee flexion. A 2D analysis is performed through single-leg squat (SLS), vertical jump (VJ), and single-leg landing (SLL). An increase of 10° or more in FPPA during a single-leg squat is categorized as Observable Dynamic Knee Valgus (DKV). |
| Lower Extremity Clinical Measurements | 6 weeks | Clinical measurements help assess the functional performance of the lower extremities and prevent injuries. Key parameters include Q-angle, hip anteversion angle, tibial torsion, ankle dorsiflexion, and rearfoot angle. Standardized tests such as goniometer-based Q-angle measurement, Craig's test for hip anteversion, and subtalar joint neutral positioning for dorsiflexion are utilized. |
| Balance Evaluation | 6 weeks | Static balance was assessed with the Single Leg Stance Test (SLST), while dynamic balance was evaluated using the Y Balance Test (YBT) in three directions: anterior, posteromedial, and posterolateral. |
| Proprioception Assessment | 6 weeks | Proprioception was evaluated using the Active Joint Position Sense (AJPS) test, which measures the ability to replicate a target angle. Measurements were conducted with a Baseline digital goniometer, and angular deviation was recorded to determine accuracy. |
