Forty-two participants with PFP were allocated to either the TTE group or the control (C) group. The TTE group received a 4-week telehealth-based exercise programme supervised through real-time video conferencing, while the C group followed a self-guided stretching exercise. Pain intensity was assessed using the Visual Analogue Scale, while functional performance was evaluated with hop tests and the step-down test. Dynamic knee valgus was measured by the frontal plane projection angle during a single-leg squat. In addition, the study used a specific health questionnaire which evaluated knee pain and function, including the self-administered Kujala Patellofemoral Questionnaire (KPQ). All outcomes were assessed both before and after the intervention.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>After the 4-week interventions, the results showed a significant interaction between the group and the time of pain intensity, functional performance and dynamic knee valgus (p&lt;0.001). The TTE group demonstrated significant pain reduction (p&lt;0.001) and improved KPQ score (p&lt;0.001), while the C group showed no significant changes. TTE participants also exhibited improved functional performance in the hop and step-down tests. Additionally, dynamic knee valgus was significantly decreased in the TTE group.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n
