Eligibility
Inclusion criteria
Inclusion criteria: 1. Able to voluntarily sign the informed consent form and willing to comply with the protocol throughout the trial; 2. Diagnosed with gout according to the 2015 American College of Rheumatology (ACR) classification criteria for gout; 3. Age >=18 years, regardless of gender; 4. Has surgical indications for tophus removal, specifically as follows: (1) Impairment of daily living functions: Tophi cause persistent pain in joints and surrounding tissues, significantly affecting the patient’s quality of life and impairing basic activities (e.g., walking, standing, dressing, climbing stairs). Surgical intervention can effectively alleviate symptoms and improve quality of life. (2) Bone, joint, and tendon destruction: Long-standing tophi induce chronic local inflammation, progressively leading to articular surface damage, cartilage erosion, and tendon injury. This manifests as joint swelling, deformity, restricted mobility, and even complete loss of joint function. Surgery not only relieves pain but also helps repair damaged tissues, restore joint function, and prevent further structural deterioration. (3) Frequent acute gout flares: Patients experiencing multiple acute gout attacks within a short period (e.g., more than three episodes within one month) indicate poor disease control. When pharmacological treatment fails to adequately relieve symptoms, surgical removal of tophi may reduce flare frequency and lower the risk of recurrent pain, thereby alleviating the overall disease burden. (4) Ineffectiveness or intolerance to medical therapy: In some cases, patients develop resistance to or experience intolerable side effects from conventional medications (e.g., NSAIDs, glucocorticoids, urate-lowering therapies), rendering pharmacological management inadequate. Surgery serves as an effective adjunctive approach by directly removing tophi, reducing local inflammation, and restoring joint function. (5) Poorly controlled or persistently elevated serum uric acid levels: Patients with chronically high uric acid levels that cannot be managed with medication are at increased risk of tophus deposition and progressive joint destruction. When non-surgical strategies fail to control the condition, surgical intervention becomes essential. (6) Presence of complications: Tophi may lead to secondary complications such as joint infection or deep vein thrombosis. In cases where uncontrolled disease poses a threat to the patient’s health or life, surgical removal of the lesion is necessary to prevent further complications. (7) Patient request: Some patients suffer prolonged, severe pain and functional limitations due to tophi and strongly desire surgical improvement in their quality of life. If surgical criteria are met and a favorable postoperative outcome is anticipated, surgery may be offered; 5. Patients requiring surgery related to gout;
Exclusion criteria
