Knee surgery pain relief: could a simple injection get you moving faster?
NCT ID NCT07090928
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether injecting the numbing drug bupivacaine into the small cuts (port sites) made during knee arthroscopy can reduce pain and help patients move sooner after surgery. Half of the 60 participants will get bupivacaine, and half will get a placebo (salt water). The main goal is to see if the drug lowers pain scores in the first hours after surgery.
