ABSTRACT

Introduction: Patellofemoral pain syndrome (PFPS), commonly referred to as runner's knee, poses a significant challenge in orthopaedic and sports medicine due to its prevalence and impact on individuals engaged in physical activities. This condition manifests as anterior knee pain and is often exacerbated during movements such as running, climbing stairs, or prolonged sitting. Aim: Aim of the study is to compare the effects of open and closed kinetic exercise with or without additional Hip strengthening exercises on pain, knee function and Q angle among the athletes with patellofemoral pain. Method: In this experimental study, 30 subjects diagnosed with PFPS were divided into two groups: Group A underwent open and closed kinetic chain exercises, while Group B performed the same exercises supplemented with hip strengthening exercises. Pre and post-test assessments were conducted using outcome measures such as the Numerical Pain Rating Scale (NPRS), Kujala Anterior Knee Pain Scale (KAKS), and Q angle measurement. Results: Both Group A and Group B showed significant improvements in NPRS, KAKS, and Q angle measurements after six weeks of intervention. However, Group B, which received hip strengthening exercises in addition to kinetic chain exercises, exhibited greater improvements in pain reduction and functional outcomes compared to Group A. Conclusion: The findings of this study highlight the effectiveness of incorporating hip strengthening exercises into rehabilitation protocols for individuals with PFPS. The combination of open and closed kinetic chain exercises with hip strengthening yielded superior outcomes in pain reduction and functional improvement compared to kinetic chain exercises alone.
