[Disorders of the patellofemoral joint induced by weight training].

The patellofemoral joint is stressed strongly during weight training. There are different individual preconditions that influence the stress distribution. Forces on tendons and cartilage are a function of angle and exercise. The most common disorders are tendinopathies and cartilage damage. Patellofemoral malalignment, high loads and overuse, uncontrolled exercises and steroids represent risk factors for injuries. Individual training concepts with controlled exercises that reduce peak loads are desirable. There is a wide scope of therapeutic options ranging from antiphlogistic therapy to the reconstruction of tendons and cartilage.
