| Objective:To investigate the effect of continuous adductor canal blocks on functional outcomes after TKA.Methods:Sixty patients scheduled for selective TKA were randomly divided into two groups, 30 patients in each group. Patients in group A receive continuous adductor canal blocks, patients in group F receive continuous femoral blocks. Record patient’s total ambulation distances, active range of knee flexion, knee extension, and the total daily opioid consumption on post operation day 1 and 2 in each group. And pain score and length of stay in hospital in each group were also recorded.Result:The ambulation distance in group A was higher than in group F. Knee active range of motion, Pain score, total opioid consumption and the length of stay in hospital in group A and F had no statistical significance.Conclusion:Compared with continuous femoral blocks, continuous adductor canal blocks provide similar analgesia for patients after TKA. Continuous adductor canal blocks may promote early ambulation after TKA. |
