Advice On Tendon Injury

A friend of mine recently got a very bad cut on their foot and it went through a tendon. Any advice on how long this could take to heal and ways to facilitate it?

Or any advice in general, common experiences.

Thanks in advance.

About five years ago, I got my left pinky finger stepped on during a softball game, severing the tendon in half. It required surgery to fish the tendon out of my wrist and reattach it. I had two pins criss-crossed through the middle knuckle to immobilize it for 4 weeks, and once they were removed about 4 months of physical therapy. To this day I still can’t make a tight fist with my left hand. Tearing a tendon sucks…plain and simple. Sorry about your buddy.
