The symptoms of knee pain after climbing may be due to the high activity level, which may cause damage to the ligaments, meniscus, cartilage, joint capsule and muscle tissue of the knee joint and lead to painful symptoms. When going downhill, the meniscus cartilage on both sides of the knee joint is mainly injured, and after the cartilage is damaged, the synovial membrane is injured and synovitis occurs, and pain is also felt, along with swelling of the knee joint. Especially when walking up hills, it is easy to cause damage to the quadriceps muscle group, which can cause pain when moving the knee joint. During clinical examination, there will be positive pressure pain around the knee joint and knee joint, and there may be a positive floating patella test, which may also affect the flexion and extension of the knee joint in severe cases. In this case, you should first avoid strenuous activities, rest in bed, elevate the affected limb, and perform bioelectric therapy and microwave instrumentation on the knee joint area. If the pain is severe, topical anti-inflammatory and analgesic drugs can be used to relieve the symptoms. If the symptoms of knee pain are not effectively relieved within a short period of time, or if the condition is progressively aggravated, it is important to go to a regular hospital in a timely manner.
