PT Pro Talk Ep 196. Patellofemoral Pain: 40 Years of Research and Key Clinical Insights with Dr. Danilo De Oliveira Silva
Jan 27, 2026
Dr. Danilo De Oliveira Silva, physiotherapist and NHMRC Emerging Leadership researcher specializing in patellofemoral pain and biomechanics. He traces 40 years of PFP research, debunks isolated VMO and routine surgery, and highlights why general quad and hip strengthening work. Listens to load management, the Envelope of Function idea, and where orthoses, taping, and neuromuscular approaches fit in.

Episode notes
From Cartilage Pressure To Conservative Care
- Early PFP theories focused on cartilage pressure and structural pathology in the knee, leading to surgeries like tibial tubercle displacement and arthroscopy.
- RCTs showed surgery equaled exercise, shifting thinking away from fixing cartilage toward nonoperative management.
VMO Fixation Gave Way To Whole-Quad Focus
- The VMO-versus-VL imbalance dominated thinking, prompting EMG and isolation training like McConnell taping and medial-focused exercises.
- Later evidence found global quadriceps atrophy, not selective VMO deficits, shifting focus to whole-quadriceps strengthening.
Hip Mechanics Matter, But May Be Consequence
- Chris Powers' hip-focused work suggested femoral internal rotation and hip adduction could drive PFP by altering patellofemoral contact.
- Hip weakness appears common in PFP but prospective studies largely show hip weakness is more likely a consequence than a consistent cause.
