The articular cartilage of the femoral condyles in athletes was analized by the arthrograms of 1168 kness (637 males and 531 females). We classified those kness into 3 groups : group A (465 kness) consisting of knee pain with known pathology, group B (206 knees) consisting of knee pain with unknown pathology and group C (497 knees) consisting of opposite knees as control. The thickness of the articular cartilage measured in group C averaged 2.7mm in medial and 2.8mm in lateral femoral condyles. The abnormality of the shapes of the articular cartilage on arthrograms was divided into 3 types, straight, concave and irregular. The abnormality of the cartilage was found in 48 knees (10.3%) in gruop A, 15 knees (7.3%) in gruop B and 24 knees (4.6%) in gruop C. We observed some cases by arthroscopy. Advanced degenerative changes were found in these cases. Those findings suggested that the cartilage injury in athletes intimately related to the knee pain.
