Content Inside: PATIENT-SPECIFIC ANALYSIS OF THE INFLUENCE OF VMO TRAINING ON PATELLOFEMORAL FORCES AND PRESSURES John J. Elias Surya P. Rai David M. Weinstein and David L. Walden Medical Education and Research Institute of Colorado Colorado Springs CO E-mail: elias@meric.info Web: www.meric.info INTRODUCTION Physical therapy regimens for treating patellofemoral pain commonly emphasize training the vastus medialis obliquus (VMO) in an attempt to strengthen the muscle and decrease the activation time. The goal of VMO training is to reduce the load applied to the lateral cartilage of the patellofemoral joint and thereby reduce the pressure applied to overloaded cartilage. Because the influence of VMO training on the patellofemoral force and pressure distributions has yet to be established the current study was performed to characterize the biomechanical benefit of VMO training for patients with patellofemoral pain. METHODS Computational models were developed to represent the knees of five patients who were scheduled for surgical treatment for patellofemoral pain (Fig. 1). The study was approved the IRB of the Medical Education and Research Institute of Colorado. The models were constructed using MRI images obtained with the knee exte ...
