Why can appear the activity obstacle of knee joint?

summary

Knee soft tissue injury refers to the tendon, ligament, fat pad, cartilage and other tissues around the knee joint. The knee joint is a large weight-bearing joint with complex structure. The medial collateral ligament sprain is more common. Why can appear the activity obstacle of knee joint? Now let me tell you something.

Why can appear the activity obstacle of knee joint?

The symptoms of knee soft tissue injury are limited to the medial side of the joint, and the severity varies according to the degree of injury. After injury, there are local swelling, pain, movement disorder and tenderness. If the pain and tenderness of bilateral collateral ligament injury are in the medial and lateral malleolus of femur, the affected side of varus or valgus may have drafting pain. If the passive motion exceeds the normal range of varus or valgus, the ligament rupture should be considered.

If the cruciate ligament injury, local swelling, but can be deep and no tenderness, if there is hematoma in the fracture joint cavity, if the fat pad under the patella strain, the onset is slow, tenderness in both sides of the quadriceps femoris tendon (patellar ligament), generally only chronic pain and no obvious swelling, such as tenderness in the tibial tubercle under the patella, more common in children with tibial tubercle epiphysitis. If there is tenderness or locked joint in the medial and lateral joint space, it indicates meniscus injury.

In the examination of complete rupture, the gap of the broken ligament can be felt at the injury site, or the fibers at the curled end of the broken ligament show irregular protrusion, or avulsive fracture fragments can be touched.

matters needing attention

In the process of normal exercise, soft tissue injuries such as muscle, tendon and ligament often occur. Because the injury will induce pain, and will affect the activity function of the affected limb, so it is necessary to carry out the correct treatment in time.
