Most issues of the hip, knee and thigh are most commonly the result of soft-tissue tightness and overuse strain from repetitive activities such as running and kicking. Prolonged sitting associated with a sedentary lifestyle can also cause tightness in the muscles of the thigh whose trigger points, when active, can generate pain in the knee. Acute injuries of the knee are also common particularly in sports involving fast changes in direction i.e. football and netball.
Applying the Bodyspanner's local-regional-global model, poor core strength, instability of the hip and pelvic as well as calf tightness can all affect the function of the knee and should be considered when treating injury in this region.
