What causes knee soreness and pain?

The knee may refer to the knee joint. Knee joint soreness or pain could be caused by overuse, poor posture, arthritis, meniscus injury, synovitis, and other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a healthcare professional. The specific analysis is as follows:

1. Overuse: Prolonged or high-intensity physical activities such as running, jumping, or mountain climbing may place excessive stress on the knee joint, leading to fatigue of the surrounding muscles and ligaments, thereby causing soreness or pain in the knee joint. It is advisable to plan exercise routines appropriately, avoid overusing the knees, and perform stretching and relaxation exercises after physical activity to help alleviate these symptoms.

2. Poor posture: Maintaining incorrect sitting or standing postures for extended periods—such as crossing legs or prolonged bending over—can easily increase the load on the knee joints, resulting in knee joint discomfort. It is recommended to maintain proper sitting and standing postures, perform regular stretching exercises, and take appropriate rest breaks to help improve these symptoms.

3. Knee arthritis: This condition may be associated with aging, excessive joint use, and other factors. After onset, local inflammation may lead to symptoms such as knee joint pain, swelling, and stiffness. Patients are advised to follow medical instructions and use medications such as celecoxib capsules, glucosamine sulfate tablets, and diclofenac sodium gel for treatment.

4. Meniscus injury: This may result from knee sprains, chronic strain, or similar factors. The meniscus is a fibrocartilaginous structure within the knee joint; when injured, it can cause knee joint pain and soreness, possibly accompanied by swelling. Patients should follow medical advice and use medications such as glucosamine sulfate capsules, Shujin Huoxue tablets (a traditional Chinese medicine), and amoxicillin capsules for treatment.

5. Synovitis: This is generally caused by intra-articular injuries, pathogen infections, or other factors. When the synovium becomes inflamed due to irritation, fluid secretion may become imbalanced, leading to fluid accumulation and resulting in discomfort such as knee joint swelling and pain. Patients are advised to use medications such as methylprednisolone tablets, ibuprofen capsules, and roxithromycin capsules under medical supervision to alleviate symptoms.

In daily life, patients should maintain good local hygiene, ensure adequate rest, and consume nutrient-rich foods such as pork ribs and chicken feet, which may benefit recovery.
