Don’t let knee pain stop you from moving forward As the saying goes: the tree withered root first exhausted, people old legs first decline. According to authoritative statistics, the incidence of knee pain in people over 60 years of age has reached a staggering 50%, especially in the cold season, the so-called “old cold leg” also began to frequent attacks, joint pain, squatting difficulties, up and down the stairs is more painful, a little walk for a while will also produce joint pain In some cases, the pain is more severe, and in others, the ability to move is basically lost. Knee pain has become a roadblock for the elderly, which greatly affects their lives. So what causes knee pain? Let’s talk about it today: 1, strain injury This injury occurs more often in people over 30 years old who walk, climb or squat more frequently. Patients may feel pain in the knee joint, and in some cases the pain increases when fully extended, but joint movement is not restricted. The symptoms are obvious after exertion. 2. Sports When the lower extremity is weighted, the foot is fixed, and the knee is slightly flexed, a sudden excessive internal rotation and knee extension or external rotation and knee extension (for example, in volleyball, the player suddenly turns and fishes to save the ball while defending) may cause a meniscus tear. 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. Stability is relatively poor when the knee is slightly flexed, and if a sudden external force causes valgus or inversion at this time, there is a risk of medial or lateral collateral ligament injury. Medial collateral ligament injuries account for the majority of clinical cases. In this 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. 3. Trauma The synovial membrane of the knee joint is one of the main structures that make up the knee joint. Synovial cells secrete synovial fluid, which can keep the cartilage surface of the joint slippery and increase the range of motion of the joint. If the synovial membrane is damaged due to trauma or overwork, it will produce a large amount of fluid, which will increase the pressure in the joint, and if not eliminated in time, it will easily cause joint adhesions and affect normal activities. Patients will feel pain, swelling and pressure in the knee joint, and the synovial membrane has a frictional sound. The most obvious feature of the pain is that when the knee joint is actively and extremely straight, especially when doing knee extension with certain resistance, the pain in the lower part of the patella will increase, and the pain is also significantly increased when it is passively and extremely flexed. 4. Ageing Most commonly seen in middle-aged and elderly people, with women predominating. Overweight load is the main cause of the disease. The knee joint may be swollen and painful, and sometimes there is a friction sound when moving the joint. The knee may develop an inversion deformity with medial pain. Treatment is based on the metaplasia of the joint, and joint replacement therapy for osteoarthritis of the knee is currently the more mature treatment internationally. 5. Cold In daily life, most joint pain is not caused by trauma, but by cold (especially persistent cold and huge temperature contrast) is the main cause of joint pain. With the development of society, people’s aesthetic and living habits have changed greatly, and people pay more attention to morphological beauty. Even in the cold winter, many people no longer wear thick cotton clothes, but try to reduce the burden on their bodies as much as possible to adapt to modern aesthetic concepts and the fast pace of life. But in the experience of beauty, people have to pay the price of joint damage, because the cold can lead to muscle and blood vessel contraction, causing joint pain. 6, bad habits For example, often wearing shoes that do not fit the foot or walking long distances in slippers and high heels can put the knee joint in an abnormal state of stress for a long time, causing chronic damage to the knee joint and causing pain. 7, other endocrine and other metabolic diseases rheumatism, rheumatoid, ankylosing spondylitis, lupus erythematosus and other immune diseases caused by the knee joint lesions. The incidence of knee pain caused by metabolic diseases such as “gout” is on the rise. Currently, there are many treatments for knee pain, such as internal and external Chinese medicine, acupuncture, massage, joint injections, arthroscopy and joint replacement, etc. It is important to choose an effective treatment according to different conditions. At the same time, the above-mentioned injuries that cause knee pain cannot be cured on their own by daily health care alone. Here is a reminder: if you have any of these pains, it is important to get a clear diagnosis from your doctor as soon as possible to avoid missing the best time for treatment.
