Abstract
The use of tourniquet in lower limb orthopaedic surgery is well established, however, it does have associated risks and complications and its use has been previously questioned. The purpose of this study was to compare postoperative pain scores, analgesic requirements and time to discharge in patients undergoing tourniquet assisted and non-tourniquet assisted routine knee arthroscopy.
A total of 40 patients were randomised to tourniquet assisted and non-tourniquet assisted groups. Arthroscopy was performed using a standardised local anaesthetic infiltration in the non-tourniquet assisted group. All patients completed a postoperative pain score.
Findings demonstrated that the incidence and mean scores for postoperative pain were significantly lower in the non-tourniquet group. Additionally postoperative analgesic requirements of patients in the non-tourniquet group were also found to be significantly lower and time spent in recovery and on the ward postoperatively was also lower in the non-tourniquet group compared to the tourniquet group.
On the basis of the results in our study we recommend abolishing the use of tourniquet in routine knee arthroscopies in the virgin knee.
