What are the symptoms of meniscus injury
The main clinical manifestations of meniscus injury are pain in the internal and external space of the knee joint, strangulation of the knee joint, snapping, and flaccid legs;
1. Pain: The pain is characterized by being fixed on the injured side, and the pain increases with the increase of activity. Some patients have no obvious pain.
2. Joint locking: when the joint is suddenly "stuck" during the activity, it cannot stretch or bend. In general, locking is rare in the acute phase, but occurs mostly in the chronic phase. After locking, the joint is sore and cannot stretch or bend. You can "unlock" it by yourself or with the help of a doctor. After "unlocking", there is often swelling of synovial reaction, and the interlocking feature is fixed on the injured side.
3. Bouncing sound: You can hear or feel the snapping sound on the injured side of the meniscus when the knee joint is moving.
4. Joint swelling: during the acute injury period of fluid accumulation, the synovium is often pulled or accompanied by other structural damage, and the joint often has blood and fluid accumulation. The swelling after joint activity in chronic stage is related to the amount of activity. The joint fluid is yellow and translucent synovial fluid, which is the result of chronic traumatic synovitis. The swelling and accumulation of joint fluid can be examined by floating patella test and knee joint effusion induction test.
5. Quadriceps femoris atrophy: meniscus injury has obvious symptoms. If it is not treated for a long time, it can cause quadriceps femoris atrophy, especially the medial femoris. However, quadriceps femoris atrophy is not a specific sign.
6. Joint space tenderness and protrusion: The joint space tenderness on the injured side of the meniscus is positive, and the tenderness points are mostly consistent with the injured part of the meniscus (for example, the body is injured, and the tenderness is in the body). You can also touch the injured meniscus, which presents a whip like protuberance in the joint space, often where the tenderness lies. Meniscal protuberance is useful for diagnosis, but it should be differentiated from cyst.
It is necessary to wear knee pads after meniscus injury. Knee pads can keep warm, improve blood circulation, reduce swelling and pain, maintain the stability of the knee joint, and play an auxiliary role in the repair of the meniscus. In particular, knee pads should be worn when the meniscus is slightly damaged or when it is recovering from meniscus injury.
