1. the act of tearing.
2. a wound produced by the tearing of body tissue, as distinguished from a cut or incision. External lacerations may be small or large and may be caused in many ways, such as a blow from a blunt instrument, a fall against a rough surface, or an accident with machinery. Lacerations within the body occur when an organ is compressed or moved out of place by an external or internal force. This may result from a blow that does not penetrate the skin, and surgical repair is usually necessary.

A first-degree laceration may not require repair, but a fourth-degree laceration, which involves the vaginal mucosa, perineal muscles, and the sphincter ani, requires extensive repair.

Patient discussion about laceration

Q. I am scheduled for scope surgery for a torn meniscus on my knee and what is the duration for recovery? Has anyone had this surgery for a torn meniscus? How did you deal with this recovery?

A. The recovery process is individual, and you cannot predict it in advance. I know someone who has done it and was able to go back to exercising regularly after 2 months. I would think the recovery from the surgery itself is a matter of few weeks until you can walk properly, however you should still give your knee a break and rest for a while after.
