ankle cartilage injury
Introduction
Introduction to ankle cartilage injury Ankle cartilage damage is most common in football players. It is reported that the incidence rate can be as high as 80%, so it is also called football cricket, which can also occur in gymnastics, skiing and other sports. Because of the frequent occurrence of osteophytes in the posterior talus, this disease was once called the ankle joint osteophyte. basic knowledge The proportion of illness: 0.04% Susceptible people: more common in football players Mode of infection: non-infectious complication:
Cause
Causes of ankle cartilage injury
(1) Causes of the disease
From the violent movement, excessive flexion of the ankle joint, back extension, internal and external dislocation caused soft joint damage.
(two) pathogenesis
The ankle joint lacks muscle and fat protection. The underside of the skin is the tendon and bone. When the ball is kicked or supported by the instep, the ankle joint is excessively flexed or stretched, so that the distal anterior and posterior edges of the humerus are repeated with the talar neck or posterior articular process. Impact squeezing, sacral articular surface wear, anterior and posterior lip of the tibia, talus neck and talus posterior process, bone hyperplasia occurs. When kicking the ball with the medial or lateral part of the foot, the internal and external valgus can cause local contact with the talus internal and external joint surface. Bone hyperplasia, repeated sprains of the ankle joint cause instability of the ankle joint, and the inferior temporal joint of the lower ankle joint can also cause cartilage damage of the talus and local osteophyte formation.
Prevention
Ankle cartilage injury prevention
Strengthen the muscle training around the ankle joint, wrap it with elastic bandages or sticky paste after injury or during competition, prevent excessive flexion and extension of the ankle joint and internal and external valgus, and avoid repeated sprains. It is an effective measure to prevent football shackles.
Complication
Ankle cartilage injury complications Complication
It can be combined with the free body of the ankle joint. In the joints such as the knee or elbow, the convex surface of some pressure epiphyses can be asymmetrical necrosis and exfoliation under the repeated action of external force, and it is free in the joint, called exfoliative osteochondritis (joint Free body). In addition, synovial metaplasia on the free body can form chondrocytes or bone cells to continue to grow, and free bodies move in the joints, also known as joint mice. If the loose body is interlocked between the joints, severe pain may suddenly appear and the joints may not move. The free body should be removed by surgery and freed within the joint.
Symptom
Ankle cartilage injury symptoms Common symptoms Ankle pain Ankle swelling Swelling under the armpit area Swelling Single leg half aching pain Knee joint effusion
Pain and activity limitation during ankle movement are the main symptoms of this disease. In the early stage, it is painful during activity. Even after rest, pain occurs. Most of the pain is in front of the ankle. When kicking the ball on the instep, the posterior part of the tendon collides with soft tissue. Squeezing produces pain, sprinting and jumping, the anterior lip and the talar neck collide to produce pain. As the epiphyseal hyperplasia, synovial sac thickening and free body formation, the joint activity is limited, until the joint mobility is significantly reduced. .
Sometimes the frictional sound of the articular surface can be felt, mainly due to the friction of the rough joint surface and the hypertrophic synovial membrane or free body.
Signs mainly include mild swelling of the joints, tenderness, friction and friction sounds, reduced joint space, and even sputum and free body.
Examine
Examination of ankle cartilage injury
X-ray is the main means of diagnosing football sputum. It can be seen that the tibia and talus neck have the formation of bone and epiphysis. The talus prominence is prolonged, and the two ridges become sharp, and sometimes the loose body shadow is seen, and the ankle joint space becomes narrow.
Diagnosis
Diagnosis and diagnosis of ankle cartilage injury
Diagnosis can be confirmed based on medical history, clinical manifestations and X-ray examination.
Ankle cartilage injury needs to be differentiated from osteoarthritis and gouty arthritis:
1. Osteoarthritis: also known as degenerative joint disease, osteoarthrosis, commonly known as bone hyperplasia. The occurrence of osteoarthritis is closely related to age and obesity. The prevalence of osteoarthritis in people under 45 years old is only 2%, and the prevalence rate in people over 65 years old is as high as 68%. In short, people from old to old age have varying degrees of osteoarthritis. All joints can be affected. However, when the small joints of the hands are involved, they are mostly the interphalangeal joints of the hands.
2. Gouty arthritis: The disease is associated with excessive and/or reduced uric acid production in the body. Excessive uric acid deposits locally in the joint causing arthritis. Its incidence is very urgent, often caused by excessive diet or stress, manifested as joint swelling and heat pain. Single joint involvement is more common, the most common site of infection is the bony prominence around the big toe.
