The Achilles Tendon is one of the most commonly injured structures in the human body. This is most likely due to the active lifestyle we now lead and the amount of time we spend on our feet.
The Achilles is the largest tendon in the body and connects your gastrocnemius/Soleus (Calve muscles) to your heel bone.
A complete Achilles Rupture involves the tendon completing snapping. Often you will hear a snap or popping sound. A partial tear will cause some soreness but you will still have full use of the ankle.
A full Achilles rupture will result in complete loss of strength and function of the ankle. You will find it extremely difficult to walk or complete any exercise. Normally at the time of the injury happening you will hear a large pop or snap sound. Often there will be a large amount of swelling around the ankle. In some cases the calve muscles will move up into a higher position behind the back of the knee.
With a partial rupture there will be no popping/snapping sound and you will still have full function of the ankle. There will be some localised soreness around the Achilles tendon and it may also feel bruised. Some swelling may be present but this will slowly decrease.
With both a complete/partial rupture the mechanism of injury is very similar
