Achilles rupture

• In Achilles tendinopathy, the tendon is palpated as thickened, tender, and crepitant with movement in the ankle joint
• Positive Thompson test in rupture (pressure on the gastrocnemius does not produce plantarflexion in the ankle joint)
• Reduced strength in active plantarflexion

Achilles rupture is noted as a gap at the muscle/tendon junction

• Squeeze the calf muscles and observe if plantarflexion occurs in the ankle joint
• In Achilles rupture absence of plantar flexion in the ankle
