Knee pain may be osteophytes, traumatic arthritis, patellofemoral arthritis, etc., and the cause should be identified in a timely manner.
1. Osteomalacia: the etiology and pathogenesis of osteomalacia of the knee joint are still unclear, and may be related to age, obesity, trauma and genetic factors. There is no obvious discomfort in the early stage, but with the development of the disease, patients will have different degrees of knee pain, swelling, limited activities and other clinical symptoms.
2. Traumatic arthritis: mainly caused by various reasons of articular cartilage trauma, characterized by secondary degeneration of articular cartilage and osteophytes. Early patients have mild symptoms, after which patients will develop typical symptoms, such as joint pain, joint swelling, joint stiffness, etc. In severe cases, it will lead to persistent joint pain. In severe cases, it can lead to persistent joint pain and movement disorders.
3. Patellofemoral arthritis: It is generally believed to be mechanical and physiological factors, and the interaction and influence of various factors ultimately lead to the occurrence of patellofemoral arthritis. It starts with knee pain, knee stiffness and inflexibility, followed by knee swelling, weakness and limited joint movement.
There may be other causes of knee pain, including chondromalacia patella, patellar fracture, bone tumors around the knee joint, synovitis of the knee joint, rheumatoid arthritis and lateral collateral ligament and cruciate ligament rupture, etc. Some patients with femoral head necrosis also have the clinical symptoms of knee pain, so it is recommended that patients seek medical attention in time, ask the doctor to clarify the specific cause, and carry out the appropriate treatment if necessary.
