What is the pain in the knee joint from time to time_ What is the sudden pain in the knee? When it comes to knee problems, it is important to have a concept of the structure, first of all, the thigh bone or femur and the tibia and fibula of the lower leg, above which there is the knee bone also known as the patella constitutes the knee joint. Between the femur and tibia there are two large cartilage discs called the medial meniscus and lateral meniscus respectively. The lower front end of the femur has a groove for the patella to move up and down, and the cartilage on the surface of these joints absorbs shock and takes pressure until they fail. The knee joint is one of the larger and more complex flexion joints in the body. It is subject to high levels of stress and is structurally stable yet flexible. Knee pain occurs from time to time, and this pain is often ignored or arbitrarily dismissed as a condition such as arthritis. In fact, there are many causes of knee pain. Common injuries that can cause knee pain are the following: 1. meniscal injury 2. fat pad strain 3. osteophytes 4. knee osteoarthritis 5. knee ligament injury. 1, meniscus injury meniscus injury is a common injury in athletes, cartilage, especially the meniscus, in sports, is the most vulnerable part of the human body. In the lower extremity weight-bearing, foot immobilization, knee joint slightly flexed, if the sudden excessive internal rotation of knee extension or external rotation of knee extension (for example, volleyball, the player in the defense suddenly turned to fish leap to save the ball action), it may cause meniscal tears. A meniscal injury can be characterized by a distinct tearing sensation in the knee, followed by joint pain, limited motion, and a walking limp. The joint exhibits swelling and slippage and pops when the joint is moved. However, this condition should not be part of your consideration. There are countless NBA players who have been affected by meniscus injuries, you can look at Brandon Roy’s injury history. Roy’s injury history, then you can probably understand the concept. 2. Fat pad strain The fat pad fills the gap at the front of the knee joint and has a stabilizing effect on the joint and reduces friction. The cause of fat pad strain may be due to trauma or long-term friction that causes fat pad congestion, hypertrophy and inflammation, and adhesions to the patellar ligament, thus limiting knee joint movement. This injury occurs in people over 30 years of age who walk, hike or squat frequently. Patients may feel pain in the knee joint, which is worse when fully extended, but there is no restriction of joint movement. The symptoms are obvious after exertion. 3, osteophytes Knee osteophytes is a chronic joint disease to the degenerative nature of the joint cartilage and adjacent bone lesions as the main feature eventually cause joint pain and stiffness is one of the important reasons affecting health status. Degenerative degeneration of the knee joint is characterized by wear and tear of the articular cartilage, followed by osteophytes. This disease is generally characterized by joint pain, especially when walking up and down stairs, and the inability to squat. This is an aseptic inflammation and there is no way to eliminate the aseptic inflammation by taking anti-inflammatory drugs. The treatment can choose pure Chinese medicine preparation cream outside the treatment of external treatment safe without side effects can be said to be the most ideal treatment method. Both to avoid oral painkillers caused by gastrointestinal discomfort liver and kidney damage and avoid the pain of surgery and post-operative complications, and recovery is not easy to relapse. 4, osteoarthritis of the knee joint This condition is mostly seen in middle-aged and elderly people, mostly women. Overload is the main cause of the disease. Arthritis can be swollen and painful, and sometimes there is a friction sound when moving the joint. The knee may have an inversion deformity and be accompanied by medial pain. 5. Knee ligament injury The stability of the knee joint is relatively poor when it is slightly flexed. If a sudden external force causes valgus or inversion at this time, it may cause medial or lateral collateral ligament injury. Medial collateral ligament injuries account for the majority of clinical cases. In this type of injury, for example, the patient will have a clear history of trauma, pain and pressure on the medial side of the knee, increased pain with passive abduction of the lower leg, and swelling on the medial side of the knee, with petechiae appearing after a few days. Knee movement will be limited. The above five types of injuries that cause knee pain cannot heal themselves by daily care alone. In everyday life, most joint pain is not caused by trauma. Prolonged cold exposure and large temperature differences in the joints are the main causes of joint pain. Especially in the fall, when cold and warm temperatures alternate, low temperatures or large temperature differences can cause muscles and blood vessels to contract, causing joint pain. If you encounter this situation, the first thing you should do is to keep as warm as possible, you can use hot compresses; the second thing is to reduce the amount of exercise and let the joints get rest. If the above methods do not make the knee pain better, then you should go to the hospital to clarify the cause.
