The main causes of knee headache include osteoarthrosis of the knee joint, other types of arthritis and soft tissue injury.
1. Osteoarthropathy of the knee joint: it is mainly caused by degenerative lesions of the articular cartilage, which can secondary cause osteophytes around the joints, bone redundancy formation, leading to narrowing of the joint space, O-shaped leg, X-shaped leg and other deformities of the knee joints, which triggers pain in the kneecap.
2. Other types of arthritis: mainly including rheumatoid arthritis, gouty knee arthritis and infectious arthritis. The first two mainly involve synovial membrane and articular cartilage, resulting in pain; the latter is mainly due to local bacterial infection invading the knee joint, resulting in pain.
3. Soft tissue injury: the most common ones are meniscus injury, medial and lateral collateral ligament injury, cruciate ligament injury, etc. Most of them belong to the category of sports injury. Most of them belong to the category of sports injuries, which cause abnormal joint movement and pain due to the abnormal internal structure of the joint.
If the symptoms of knee headache are not relieved, or accompanied by other symptoms, you should go to the hospital in a timely manner, after clarifying the cause to give targeted treatment.
