How is a popliteus strain diagnosed?
A popliteus strain requires a comprehensive subjective and objective assessment to be carried out by a physiotherapist. It is a difficult injury to diagnose because the popliteus muscle is covered by a large muscle, the gastrocnemius. The experienced physiotherapist will test the knee through various movements and palpation. If the knee cannot fully extend or flex and is met by a hard end feel then a popliteus strain may be suspected. The physiotherapist will also palpate the popliteus muscle for tenderness. Again, if this is positive then a popliteus strain may be suspected.
