Exclusion criteria: Acute knee pain, Prior knee surgery, Patients on anticoagulant medications, psychiatric illness, Steroid/ Hyaluronic injections taken in the past 3 months. Result: The pain intensity was much lower post block when compared to baseline pre-procedure values of both the indices throughout 6 months follow up. The patient__ampersandsignrsquo;s painless standing/mobility period also increased significantly after injection as it was before the procedure. Conclusion: Notable heterogeneity (p __ampersandsignlt; 0.001) was noticed and concluded the Funnel Plot. In our result, it was observed that the age group 30-39 had a significantly higher mortality rate.
