Is surgery necessary for a partial tendon laceration or does it heal back together on its own?

It could. First let us define what partial rupture means: less than one third of the tendon wedth. Partial tendon laceration could heel on his own. Her the two senario.1- you know the tendon is partially lacerated and you precaution to let heel by it self. 2- you do not know is partially rupture and you my not take the precaution needed to heal it, in this situation it may rupture completely. Thank you.
Depends. Which tendon finger flexors are usually repaired achilles partial tears can be treated witgout surgery.
