What would happen if a muscle was torn?

Answer 1

Basically when a muscle is torn its going to be very painful to move and very difficult to move. You will have limited control over that muscle for a good few weeks. Of course with almost any injury, time heals it. It becomes less painful and mends itself over the course of a few weeks. You will be able to move it again quite easily within a month.

However, when it does mend and grow back, it will be weaker than before, much weaker. It's nearly impossible to have the muscle preform like it used to. But with much physical therapy and LOTS of usage (Note: usage, DON'T overwork it especially so soon) and training, it is possible to make a full recovery and preform just as well if not better than before.

The above is true, however you must realize if you aren't an athlete or do intense physical training on a daily basis, chances are that muscle will never make a full recovery back to the state it was before the tear.

Answer 2

One possibility for a result to an injured tissue is necrosis. Cells will become inflamed by a series of chemical reactions to the injury and the damaged cells will go through phases of acute lethal injury. The phases are; cellular swelling, fatty degeneration, hyaline degeneration, Mucoid degeneration, colloid degeneration, and finally irreversible death. Autolysis is a process of absorbing and removing the dead cells from their location as waste while new cells will grow from healthy surrounding cells during the healing process. Necrobiosis is the natural death cycle of cells which typically are alive for about 120 days.

There are many more possible things that can happen if tissues are injured. Choosing a tissue and describing the injury will result in more specific possibilities.
