Dependence between the insertion type and the plantaris tendon course variant

PT course variant	Type of insertion of PT	PT course characteristics
A	1	PT crosses the space between GM and SM, and runs on the medial part of the leg, medial to Achilles tendon PT runs separately from Achilles tendon
A	2	PT crosses the space between GM and the SM, and runs on the medial part of the leg, medial to Achilles tendon PT closely adheres to Achilles tendon, within single paratendon
B	3	PT crosses the space between GM and SM, and descends along the medial part of the leg, and next runs anterior to Achilles tendon PT has insertion anterior to the calcaneal tendon
B	4	PT crosses the space between the GM and SM, and runs on the medial part of the leg, and next runs anterior to Achilles tendon PT inserts to deep crural fascia of the leg
A	5	PT crosses the space between GM and SM, and runs on the medial part of the leg, medial to Achilles tendon PT has a very wide insertion over the Achilles tendon

PT plantaris tendon, GM gastrocnemius muscle, SM soleus muscle
