What is a partially torn Achilles tendon?
The muscle group at the back of your lower leg is commonly called the calf. The calf comprises of 2 major muscles one of which originates from above the knee joint (gastrocnemius) the other of which originates from below the knee joint (soleus). Both of these muscles insert into the heel bone via the Achilles tendon (figure 1). During contraction of the calf, tension is placed through the Achilles tendon. When this tension is excessive due to too much repetition or high force, the Achilles tendon can be torn. Tears to the Achilles tendon can range from a small partial tear whereby there is minimal pain and minimal loss of function, to a complete rupture which may require surgical reconstruction.
