Proximal versus distal adductor canal catheters for total knee arthroplasty: a systematic review and meta-analysis of randomized controlled trials
Pooled result · Cumulative opioid consumptionResult — go to the resultMD −4.86 95% CI −15.19 to 5.47Authors' conclusion
These findings suggest that proximal vs distal adductor canal catheter placement in patients undergoing TKA may be equally effective for the outcomes of opioid consumption in the first 24 hr, pain scores at rest, and pain scores with movement in the first 24 hr.
