Medial Tibial Stress Syndrome (MTSS)

Classic symptoms for MTSS are palpatory tenderness along the medial border of the end 2/3 of the tibia that is induced with activity and settles at rest.

There is no clinically proven mechanism for this injury however increased tibial bending moments as a cause is increasing in popularity. Theoretically it makes sense as during running our steps become narrower and as a result we suffer increased varus (inward tilt) stress on the tibia.

Treatment would aim at reducing this varus stress and specific orthoses can assist however other factors must be looked at including conditioning, footwear and training errors.
