Introduction
Knee replacement refers to knee arthroplasty. Swelling four months after knee replacement surgery may be caused by physiological factors, or by pathological factors such as local infection or synovial hyperplasia. Treatment may include general management and medication. Knee replacement surgery can cause localized wear on bone surfaces and involves a certain degree of tissue trauma, leading to an acceptable level of pain and swelling.
Knee joint replacement refers to knee arthroplasty. Swelling four months after knee replacement surgery may be caused by physiological factors, or by pathological factors such as local infection or synovial hyperplasia. Treatment may include general management and medication. Specific details are as follows:
1. Physiological Factors
Knee joint replacement surgery can cause localized wear on bone surfaces and involves a certain degree of tissue trauma, leading to acceptable levels of pain and swelling. Over time, these swelling and pain responses gradually diminish.
2. Pathological Factors
1) Local Infection
If proper postoperative care is not performed and local bacterial infection occurs, pain and swelling may develop. In such cases, medications such as clarithromycin tablets or penicillin V potassium tablets may be taken as directed by a physician.
2) Synovial Hyperplasia
If the synovial area is irritated during surgery, it may lead to synovial hyperplasia, resulting in symptoms such as redness, swelling, and pain. Medications such as celecoxib capsules or diclofenac sodium enteric-coated tablets may be taken under medical guidance.
In addition to the above causes, swelling could also result from conditions such as chronic nephritis, deep vein thrombosis, or heart failure. Adequate rest should be ensured and excessive fatigue avoided.
