Inflammation due to excessive load (overuse) on patella tendon – commoner in jumping, landing, cutting and kicking activities (ie place strain on extensor mechanism). May co-exist with patellofemoral syndrome.
Anterior knee pain or diffuse ache aggravated by jumping – usually gradual onset. Tendon may be painful to palpation, especially at distal pole of patella. Initially pain only tends to occur after activity (disappears in 1hr to 1 day) progresses to be present during activity and persists.
Manual therapy – transverse frictions
Strengthening - eccentric
