Still having pain 3 months after knee replacement may be related to surgical trauma, inflammatory response, infection or knee adhesion.
1. Surgical trauma: Knee replacement requires cutting the skin, subcutaneous tissue, joint capsule, and removing the diseased cartilage tissue, so the surgery is more traumatic, which is likely to cause pain symptoms in the early and distant postoperative period. As the damaged tissue recovers, pain symptoms will gradually ease. If the pain symptoms continue to be unrelieved or gradually worsen, the cause of the disease needs to be clarified.
2. Inflammatory reaction: 3 months after knee replacement, the pain can also be caused by aseptic inflammatory reaction during the repair of tissue damage, and then pain symptoms appear under the stimulation of inflammation.
3. Infection: If the knee joint replacement is infected after surgery, it will also cause knee joint pain due to infection, and the pain symptoms will gradually worsen, accompanied by fever, joint swelling and other manifestations. Inflammation indicators or changes in indicators such as nuclear scanning of the knee joint can assist in the diagnosis.
4. Knee joint adhesion: 3 months after the knee replacement, if the knee joint adhesion is caused by the lack of joint rehabilitation exercise, knee joint pain symptoms will also occur. Generally, the examination can see the knee flexion or extension dysfunction.
Therefore, when there is still pain 3 months after the knee replacement, it is recommended to go to the hospital in time, to clarify the cause of the disease and then actively treat it.
