Treatment for a knee injury depends on the precise injury. For fractures, a surgeon might need to insert a screw, pin, or plate to hold bones in position. If tendons or ligaments have been stretched or torn, then surgery might be required. Some knee injuries respond well to conservative treatment like rest, ice, and compression, but even conservative treatment often requires that a person be off their feet for weeks.
Some knee injuries become degenerative and can lead to arthritis or other chronic conditions. These victims will face a lifetime of medical care to help them cope.
