“Recent studies of adult Swedish soccer players who tore an A.C.L. found that, within 12 to 14 years after the injury, 51 percent of the female players and 41 percent of the men had developed severe arthritis in the injured knee. The same time frame could have an injured 10-year-old dealing with a severely arthritic knee before he or she is 25.”
