The main muscle imbalance associated with Patellofemoral Pain Syndrome (PFPS) often involves a weak Vastus Medialis Oblique (VMO) muscle, particularly in conjunction with timing issues. The VMO is a part of the quadriceps muscle group and plays a crucial role in stabilizing the patella (kneecap) during knee movements. When the VMO is weak or does not activate properly when the knee is flexed or extended, it can lead to inadequate control of the patella, resulting in improper tracking, excessive lateral movement, and ultimately, pain and dysfunction in the knee.

This timing issue can contribute to an imbalance where other muscles, such as the Vastus Lateralis, may become overactive, further exacerbating the misalignment of the patella. As a result, strength and coordination of the VMO are essential for maintaining proper knee function and stability, making its weakness a significant factor in PFPS.

In contrast, while overactive hamstrings, strained calf muscles, and strengthened quadriceps can influence knee mechanics and overall functionality, they are not the main muscle imbalances directly linked to PFPS in the way that a weak VMO with improper timing is. Focusing on the VMO's strength and activation
