Kinesio taping vs. Bracing for patellofemoral pain syndrome in runners

Background: Patellofemoral Pain Syndrome (PFPS), often referred to as "runner’s knee," is among the most common overuse injuries in runners. The management of PFPS often includes external support methods like kinesio taping (KT) and patellar bracing (PB). While both aim to improve patellar alignment, reduce pain, and optimize function, their comparative efficacy remains debated. Objective: This study aims to critically compare the effectiveness of kinesio taping versus patellar bracing in alleviating pain, improving knee function, and supporting long-term rehabilitation in runners diagnosed with PFPS. Methods: A narrative review and meta-analytical approach were applied to synthesize data from randomized controlled trials (RCTs), cohort studies, and systematic reviews published between 2010 and 2024. Key outcome measures include pain intensity (VAS), functional improvement (Kujala Score), and biomechanics-related variables (Q-angle, patellar tracking). Results: KT demonstrates short-term pain relief and proprioceptive benefit, especially during activity. Bracing, on the other hand, shows stronger biomechanical correction in patellar alignment and greater impact on pain during weight-bearing phases. Studies suggest both methods are comparable in short-term pain reduction, but bracing shows superior outcomes in long-distance runners over 8+ week follow-up. Conclusion: While both kinesio taping and patellar bracing provide therapeutic benefit for PFPS in runners, patellar bracing may offer more consistent improvements in long-term function and biomechanical stability. KT remains a valuable adjunct, particularly for short-term pain control and proprioceptive feedback. Individualized interventions considering anatomical alignment, symptom duration, and training load are essential.
