Relationship between Sagittal Spinopelvic Parameters and Knee Joint Function, Position Sense, and Dynamic Balance in Chronic Patellofemoral Pain

Background: Patellofemoral pain (PFP) constitutes one of the most debilitating knee illnesses worldwide. The back and the lower extremities link closely; yet, however, no clarification was found to explain the fundamental and compensatory factors. Purpose: This study investigates the link between sagittal spinopelvic characteristics; (pelvic tilt (PT), lumbar lordosis (LL)) and knee joint function, position sense (JPS), and dynamic balance. Methods: Forty-two (36 females and 6 males) participants with chronic patellofemoral pain syndrome (>3 months). Their ages were (18 to 35 years old). Participants were examined for their degree of pelvic tilt, lumbar lordosis angle, knee joint function, knee joint position sense, and dynamic balance. Results: Pelvic tilt exhibited a moderate negative connection with JPE and a moderate positive relationship with the posterolateral direction of (Y) balance test. However, no significant link detected between pelvic tilt and AKPS, anterior, posteromedial, and composite Ybalance tests. Lumbar lordosis demonstrates a moderately negative significant association with AKPS but no with other measures. Conclusion: The spinopelvic parameters assessment should be considered and addressed in the assessment and management of participants with chronic PFPS for improved outcomes.
