AbstractFifty patients were randomly recruited to receive either femoral nerve block (0.375% Bupivacaine) or an intraarticular local anaesthetic injection for pain control for arthroscopically-assisted ACL reconstruction. Both groups were evenly matched for age ( t-test p >0.05). Tourniquet time did not differ significantly between the groups ( t-test p=0.24). The VAS pain levels were not significantly different at 4 h and the first morning postoperatively in both groups. Femoral block (Median VAS: 20 & 18.5) did not confer a significant advantage (Mann Whitney U test p =0.36, 0.67) over intraarticular injection of bupivacaine (Median VAS: 18 & 20). There was no correlation between tourniquet time and postoperative pain ( r=0.19, 0.08). All patients but one were discharged home on the first postoperative morning. Our study demonstrates that pain levels can be sufficiently controlled by intraarticular infiltration of bupivacaine coupled with oral analgesia. The level of pain relief achieved could allow this procedure to be performed in a day surgery setting.
