Purpose
This work aimed at studying the effect of tourniquet use on surgical performance and peri-operative outcomes of anatomic single-bundle ACL reconstruction.
Methods
Eighty-four patients undergoing ACL surgery were randomized into two groups: the tourniquet (A) group and the non-tourniquet (B) group. Post-operative pain, need for analgesics, the volume of blood obtained in the drain, girth diameter changes in the thigh and calf, muscle strength and amount of haemarthrosis were used as outcome measures to compare the two groups.
Results
Fifty-eight patients were available for analysis. In the A group, the degree of pain and need to analgesics was significantly higher at 4 and 10 h. The volume measured in the surgical drain, at 24 h post-operative, was higher in the A group (p = 0.001). The calf and thigh girth diameters at 2 weeks showed a highly significant girth difference between the two groups (p = 0.001).
Conclusion
This study showed that tourniquet use in ACL reconstruction increases immediate post-operative symptoms of pain and haemarthrosis and that the effects on muscle strength are only temporary. The tourniquet can be replaced by using of a mixture of morphine and adrenaline with no interference with the quality of visibility, nor operative time.
