Osteochondritis lateral femoral condyle

osteochondritis dis´secans osteochondritis resulting in the splitting of pieces of cartilage into the joint, particularly the knee joint or shoulder joint.osteochondritis resulting in the splitting off of a piece of articular cartilage due to fissure formation in an area of dysplastic subarticular cartilage so that it forms a flap or separates completely and falls into the joint space ('joint mouse'); occurs most commonly on the head of the humerus and distal condyles of the femur in dogs and pigs. - K wire is followed by placement of cannulated lag screw, which is counter-sunk beneath the cartilagenous surface;; - Lipscomb Method: - partially detached lesions are reattached using K wires driven from within the knee joint and then driven out of the femoral cortex and the skin; - the K wire is then pull proximally until the distal end is no longer visible from within the joint; - the K wires are left subcutaneous in the distal thigh, and are removed after 6-8 weeks Team physician #8. Compressive fixation of osteochondritis dissecans fragments with Herbert screws. Osteochondritis dissecans of the knee with loose fragments.Spontaneous healing is usual unless there is an unstable fragment.History, pathophysiology and current treatment concepts. There is flattening and irregularity of the weight-bearing surface of the lateral femoral condyle, consistent with osteochondritis dissecans of the knee.Physical examination typically reveals an effusion, tenderness, and a crackling sound with joint movement.X-rays of the other knee (not shown) demonstrated similar changes.

Tibial cortical bone peg fixation in osteochondritis dissecans of the knee. Osteochondritis Dissecans of the Knee: Long-Term Results of Excision of the Fragment.Kinds of osteochondritis include osteochondritis deformans juvenilis, osteochondritis dissecans, osteochondritis ischiopubica, osteochondritis juvenilis, and osteochondritis necroticans.The weight-bearing surfaces of the lateral femoral condyle, tibia or patella may also be involved.Signs of instability include large size (1cm), cyst-like lesions beneath a fragment, contrast beneath a fragment on contrast arthrography, and loose body. The differential diagnosis includes normal fusing apophysis (painless) or acute osteochondral fracture.There is subchondral sclerosis, and a lucent area suggesting subchondral cyst formation.

This loss of blood flow causes the subchondral bone to die in a process called avascular necrosis.
