Runner’s Knee and ITBS Biomechanics: Gluteus Medius Weakness & 6-Week Rehab

Among distance runners and marathon athletes, Patellofemoral Pain Syndrome (PFPS / Runner’s Knee) and Iliotibial Band Syndrome (ITBS) constitute the most prevalent overuse injuries.

Biomechanically, knee joint pathology is rarely an isolated local failure. Rather, the knee serves as an innocent victim of proximal biomechanical dysfunction—specifically, gluteus medius weakness, contralateral pelvic drop (Trendelenburg gait), and dynamic knee valgus.

Section VI: Patellar Tracking Alignment and VMO Strengthening

Terminal Knee Extensions (TKE) isolate the vastus medialis oblique, stabilizing patellar glide within the femoral trochlea.

Section VII: Complete 6-Week Rehabilitation Protocol and Trendelenburg Test

Progressive phase 1-3 clinical exercises restore vastus medialis and gluteus medius dynamic control, realigning the patellar groove.
