The plantaris is really a puny little muscle with that long tendon.

It is so small that many consider it a remnant of a muscle that was bigger in some prehistoric relative.

"In human beings, the plantaris tendon is a rudiment of a large muscle, which in some of the lower animals is continued over the calcaneus and inserted into the plantar aponeurosis. In cows and sheep, the plantaris is a major muscle, from which most xenograft material is obtained."

In fact it is considered so unimportant, that if a tendon elsewhere in the body is too severely damaged to be repaired, surgeons will remove the plantaris tendon from the leg, and use it as a living transplant to replace the injured tendon elsewhere in the body, most commonly for injured hand tendons.

"The plantaris tendon is an extremely tensile structure used for flexor tendon replacement in hand surgery, and it is not too thick for revascularization at the graft site."

But it even can be used to replace a torn heart valve!

"We now put forward a hypothesis, extrapolated from hand surgery, for use of the plantaris tendon in heart valve repair.This proposal, if implemented, would increase the supply of autogenous donor tissue for valve repair, thereby enhancing the surgeon's armamentarium. The report describes a novel technique that in our judgment warrants future clinical development. "

But despite how small and unimportant the plantaris muscle/tendon is, if you pop it, it really hurts.


[By the way, I developed inflammation in the plantaris muscle about 10 years ago.
I had to pick up my daughter after a class she was taking at a nearby university.
I had an hour to kill, so I practiced serving every day for much of that hour.
I kept trying to get into a bigger and bigger bow shape to increase power.
When it started hurting behind the knee, I mentioned it to a physical therapist who works with a lot of tennis players. She said it sounds like "tennis leg" involving the plantaris.
With some rest and a return to a less insane amount of serving practice it has never bothered me again.]
