What is the cause of degenerative changes in both knee joints, and what should be done?

Generally, degenerative changes in both knee joints are mainly caused by factors such as aging, excessive joint use, obesity, joint injuries, and osteoporosis. If you experience any discomfort, please seek medical attention promptly. A detailed explanation is as follows:

1. Aging

With increasing age, the cartilage and ligaments within the joints gradually lose elasticity and moisture, leading to joint degeneration. Engaging in appropriate low-impact exercises such as swimming or cycling can help strengthen muscle strength and protect the joints.

2. Excessive Joint Use

Individuals who engage in heavy physical labor or high-intensity sports over a long period experience repeated friction and pressure on their joints, accelerating joint degeneration. Adequate rest and exercise can help strengthen the muscles surrounding the joints.

3. Obesity

Obesity places additional pressure on the knee joints, intensifying cartilage wear and accelerating the progression of degenerative changes in both knee joints. Weight loss through dietary control and increased physical activity can help reduce the stress on the knee joints.

4. Joint Injury

Factors such as sprains and ligament tears can cause joint injuries. Joint injuries may compromise the stability and alignment of the knee joint, and even after recovery, minor irregularities may remain. This can lead to uneven pressure distribution across the joint surface, accelerating cartilage wear and potentially causing symptoms such as pain and restricted movement. It is recommended to use medications such as diclofenac diethylamine gel, indomethacin cataplasm, and Dahuoluowans (capsules) as directed by a physician.

5. Osteoporosis

Osteoporosis is primarily caused by calcium deficiency and unhealthy lifestyle habits. It reduces bone strength, increasing the risk of fractures and joint injuries, thereby indirectly accelerating degenerative changes. Symptoms such as kyphosis (curvature of the spine) and increased susceptibility to fractures may occur. Treatment may include medications such as calcium acetate capsules, calcium lactate tablets, and alendronate sodium tablets, under the guidance of a qualified physician.

In daily life, it is important to reduce the intake of high-calorie foods and combine this with appropriate aerobic exercises such as brisk walking or swimming, to maintain body weight within a normal range, thereby reducing the burden on the knee joints.
