Key Takeaway
Interpret postoperative complication rates after tophaceous gout surgery cautiously given very low certainty evidence.
This meta-analysis pooled 18 retrospective studies to estimate postoperative complication rates after surgical treatment for tophaceous gout. The authors report pooled rates for infection, delayed wound healing, recurrence, reoperation, amputation, and overall complications.
The pooled rate of overall complications was 24.0% (95% CI 14.0%-38.1%). Postoperative infection occurred in 11.3% (95% CI 8.0%-15.7%), delayed wound healing in 9.9% (95% CI 5.1%-18.2%), recurrence in 8.5% (95% CI 4.7%-14.9%), reoperation in 9.7% (95% CI 5.5%-16.7%), and amputation in 3.7% (95% CI 2.0%-6.8%).
The authors state that certainty of evidence was very low for all outcomes. No comparator was reported, and follow-up duration was not reported. The analysis is based on retrospective studies, so the findings describe associations rather than causal effects of surgery. Funding and conflicts of interest were not reported.
These estimates suggest that surgical treatment for tophaceous gout carries measurable postoperative risks, particularly infection and overall complications. However, the very low certainty of evidence and the retrospective nature of the included studies limit the strength of these conclusions. Clinicians should interpret these rates cautiously and consider them alongside individual patient factors and institutional experience.
How this fits prior evidence
Prior coverage has addressed gout epidemiology and management, including a global meta-analysis reporting 22% hyperuricemia prevalence in type 2 diabetes, a treat-to-target strategy that improved remission versus symptom-driven care, and mechanistic reviews of the gut-joint axis and neutrophil extracellular traps. This meta-analysis extends that coverage by focusing on surgical outcomes in tophaceous gout, a setting not addressed in those prior items. It provides pooled complication rates where previous coverage was limited to medical management and pathophysiology. The very low certainty of evidence contrasts with the more established, though still limited, evidence for treat-to-target urate-lowering therapy.
Researchers analyzed 18 different studies to look at the outcomes for patients undergoing surgery to treat tophaceous gout. Because the data came from retrospective studies, the overall certainty of the evidence is very low. This means the findings should be viewed as preliminary rather than definitive proof of specific risks.
The analysis found that patients who underwent surgery experienced several complications. These included a 11.3% rate of postoperative infection and a 9.9% rate of delayed wound healing. Other reported issues included a 8.5% recurrence rate and a 9.7% rate of reoperation. The study also noted that 3.7% of patients required amputation, and 24.0% of patients experienced some form of overall complication.
Because the evidence is not very certain, these numbers should not be used to predict an individual's specific outcome. However, the data shows that surgical treatment for gout is associated with measurable risks. Patients should discuss these potential complications with their doctors to understand what to expect during their specific treatment plan.
What this means for you:
Surgery for tophaceous gout is linked to risks like infection and wound healing delays, but evidence is currently weak.
Common questions
What are the risks of surgery for tophaceous gout?
The study found several risks for patients undergoing surgery for tophaceous gout. These include a 11.3% rate of postoperative infection and a 9.9% rate of delayed wound healing. Other complications included a 9.7% rate of reoperation and a 3.7% rate of amputation.
How common are complications after gout surgery?
The analysis reported that 24.0% of patients experienced some form of overall complication after surgery. These complications included infection, delayed wound healing, and reoperation. However, the researchers noted that the certainty of this evidence is very low.
Is the evidence for these risks very strong?
No, the evidence is not very strong. The findings came from 18 retrospective studies rather than a single large trial. Because of this, the researchers reported a very low certainty of evidence for all outcomes measured in the study.
BACKGROUND: Surgical treatment remains necessary for selected patients with tophaceous gout, particularly when mechanical limitation, nerve compression, ulceration, infection, deformity, or failure of conservative treatment is present. However, postoperative outcomes after surgery for tophaceous gout have not been comprehensively quantified. This systematic review and meta-analysis evaluated postoperative complication profiles and recurrence burden after surgical treatment for tophaceous gout.
METHODS: A systematic search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted from database inception to March 25, 2026. Original studies reporting postoperative outcomes after surgical treatment for tophaceous gout were included. Pooled event rates with 95% confidence intervals (CIs) were calculated using a random-effects single-arm meta-analytic approach. Primary outcomes were postoperative infection, delayed wound healing, and recurrence. Secondary outcomes were reoperation, amputation, and overall complications. Functional outcomes were summarized descriptively.
RESULTS: 18 retrospective studies were included. The pooled postoperative infection rate was 11.3% (95% CI 8.0%-15.7%), delayed wound healing 9.9% (95% CI 5.1%-18.2%), and recurrence 8.5% (95% CI 4.7%-14.9%). Secondary pooled rates were 9.7% (95% CI 5.5%-16.7%) for reoperation, 3.7% (95% CI 2.0%-6.8%) for amputation, and 24.0% (95% CI 14.0%-38.1%) for overall complications. Significant subgroup differences were identified only for infection according to anatomic site and intervention type. Sensitivity analyses showed that pooled estimates were robust. The certainty of evidence was very low for all outcomes.
CONCLUSIONS: Surgical treatment for tophaceous gout is associated with measurable postoperative risks, particularly infection and overall complications. These findings support careful perioperative counseling, structured postoperative surveillance, integrated long-term urate-lowering management, and more standardized reporting of perioperative risk factors and postoperative outcomes in future surgical studies of tophaceous gout.
