Anterior cruciate ligament injury meniscus injury

When people have suffered anterior cruciate ligament injury and meniscus injury, they can no longer move freely. It is best to go to the emergency room as soon as it happens. At this time, you will find that your joints are obviously swollen, which means that there is very serious blood accumulation in your joints. You need to rest more and stay in bed as much as possible. This will make the recovery better.

1. In the acute phase, if the joints are obviously swollen, it indicates that there is a lot of blood accumulation. The accumulated fluid can be extracted under strict aseptic operation, and the elastic bandage can be used to apply slight pressure. If the joints are locked, try to go to a regular hospital for manual release. Cold compress treatment after injury is very important, and the affected limb needs to be elevated for rest. Generally, long-leg external fixation is required to keep the affected knee in an extended position for 4-6 weeks. External fixation can be performed using a plaster tube or a brace to ensure good shaping and reliable fixation.

2. Generally, after 4 weeks, you can walk with partial weight bearing under the protection of the brace, and gradually walk with full weight bearing. During the recovery period, you should actively exercise your quadriceps to prevent muscle atrophy.

3. Chronic stage In the chronic stage, the torn meniscus will damage other structures of the knee joint and cause traumatic arthritis. Therefore, if a clearly diagnosed meniscus injury is ineffective with non-surgical treatment and the symptoms and signs are obvious, surgical treatment should be performed as soon as possible. The current routine surgical procedure is arthroscopic meniscectomy or partial meniscectomy. Normal function can be basically restored 2 to 3 months after surgery.

1. Joint space tenderness sign: Joint space tenderness near the damaged meniscus, with a high positive rate and the greatest clinical significance;

2. McBurney test: The patient lies in the supine position with the hip and knee flexed. The examiner applies internal rotation and adduction, abduction and extension, external rotation and abduction, adduction and extension to the calf during the process of flexing and extending the knee joint. If there is pain or clicking, the test is positive. This test is the most widely used examination method in clinical practice. In recent years, it has been found that its positive rate is lower than that of joint space tenderness sign.

3. Abrasion test (Apley test): The test is performed in the prone position with the affected knee flexed 90°. The examiner presses down hard on the ankle and performs rotational grinding. It is positive when there is pain in a certain position. It may be positive in some cases.

4. Magnetic resonance imaging (MR) examination: It is an important examination for diagnosing meniscus injury, with an accuracy rate of over 90%. It can not only confirm the diagnosis, but also determine the shape and range of the tear, and guide the formulation of treatment and rehabilitation plans.

4. Arthroscopy: It is the most accurate examination method, but it is an invasive examination. It is generally only used as a treatment method when there are clear indications.
