Are there long-term sequelae from soccer?

A long-term soccer career seems to increase the risk for early development of osteoarthritis in the lower extremity. Soccer constitutes a risk for osteoarthritis in two different ways. First, by the increased risk for knee injuries in soccer, such as meniscus and anterior cruciate ligament injuries; and second, by the high loading on hip and knee joints that occurs in soccer. The risk for these undesirable effects of soccer are higher in top-level players.
