In order to explain the age difference in shearing injuries of the articular bone-cartilage in sports, shear strength of the bone-cartilage junction and subchondral cancellous bone from the pig patellofemoral joint was investigated along with histological obswevation in fractured specimens. The strength of different layers in the adult pigs increased in order of the tensile strength for articular cartilage, the shear strength for bone-cartilage junction, and subchondral cancellous bone. The young pig showed structural weakness of bone-cartilage junction and cancellous bone. The difference of the mechanical properties of cartilage, bone-cartilage junction, and cancellous bone in articular end, with maturity, causes the different type of bone-cartilage injuries such as osteochondritis dissecans, osteochondral fracture and chondromalacia in the young, and osteoarthritis in adults.
