Introduction
The knee may refer to the knee joint. Knee joint pain could be caused by factors such as overuse, aging, osteoarthritis, patellar chondromalacia, or rheumatoid arthritis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Patients are advised to engage in appropriate physical exercise, such as running or walking, drink plenty of warm water, and gently massage the affected area.

Under normal circumstances, the term "knee" refers to the knee joint. Knee joint pain may be caused by factors such as overuse, aging, osteoarthritis, chondromalacia patellae, or rheumatoid arthritis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Overuse: Prolonged standing or high-intensity knee joint activities such as running and jumping can easily lead to muscle fatigue around the knee joint and wear of the articular cartilage, thereby causing joint pain. It is advisable to reasonably schedule exercise and rest periods, avoid maintaining a single posture for extended periods, and perform appropriate muscle stretching and relaxation exercises.

2. Aging: With increasing age, articular cartilage may gradually wear down, potentially leading to narrowing of the joint space and decreased joint stability, resulting in joint pain. Strengthening muscular support around the joint through targeted strength training can improve joint stability and help alleviate these symptoms.

3. Osteoarthritis: This condition may be associated with factors such as aging and obesity. Following onset, degenerative changes in the articular cartilage may lead to knee joint pain, possibly accompanied by local stiffness. Patients are advised to follow medical instructions when using medications such as meloxicam capsules, glucosamine hydrochloride tablets, and Gukang capsules for treatment.

4. Chondromalacia Patellae: This may be related to long-term strain on the knee joint or developmental abnormalities of the patella. After onset, swelling of the cartilage surface of the patella may cause knee joint pain, possibly accompanied by restricted movement. Patients are advised to follow medical instructions when using medications such as glucosamine hydrochloride capsules, alendronate sodium tablets, and Zhuanggu Guanjie pills for treatment.

5. Rheumatoid Arthritis: This is generally caused by factors such as pathogen infection or living in damp environments. After onset, inflammatory changes in the synovial membrane of the joint may lead to knee joint pain, possibly accompanied by redness and swelling of the joint. Patients should use medications such as Qingpeng ointment, diclofenac sodium sustained-release tablets, and methylprednisolone tablets under medical supervision to manage symptoms.

In daily life, patients are encouraged to engage in moderate physical exercise, such as running or walking, drink plenty of warm water, gently massage the affected area, maintain adequate sleep, all of which may benefit recovery.
