To determine the effectiveness of genicular chemical neurolysis for pain reduction in patients with chronic non-cancer knee pain and to assess the incidence of adverse events, specifically focusing on the relationship between treatment outcomes and safety.
Key Findings:
All studies indicated improved pain or functional outcomes following chemical neurolysis, highlighting its potential as a treatment option.
No serious adverse events were reported across the studies, suggesting a favorable safety profile.
The studies varied in terms of chemical agents used, imaging guidance, and outcome measures, indicating a need for standardization.
Interpretation:
Chemical neurolysis of the genicular nerves is a promising treatment for chronic knee pain; however, the current literature is limited by heterogeneity in study design and small sample sizes, which may affect the generalizability of the findings.
Limitations:
Study heterogeneity in nerve targets and techniques.
Small sample sizes across included studies.
Lack of high-quality randomized controlled trials for definitive conclusions.
Potential bias in study selection and reporting.
Conclusion:
Chemical neurolysis of genicular nerves shows potential as a non-surgical option for chronic knee pain, warranting further high-quality research.
A long-term cohort study found that obesity was not associated with worse patient-reported outcomes or higher reoperation rates following total ankle replacement in optimized surgical candidates.
