Abstract
Introduction
To reduce several disadvantages many surgeons are not using tourniquet in TKA. Here we compared functional outcome along with pain and blood loss in sixty patients.
Material and Method
60 patients who underwent TKA wererandomized into a tourniquet group (n2 = 30) and a non-tourniquet group (n1 = 30). All operations were performed by the samesurgeon and follow-up was for 6 month. Primary outcomes werefunctional and clinical outcomes, as evaluated by KSS and postoperative pain. Secondary outcomes were blood loss, surgical time and visibility, extensor lag and Knee ROM, DVT and radiolucency.
Result
Without significant difference in operating time, there was significant less VAS score on post operative day 0, 1 and 3(P-value=0.0,.0.01,0.03 respectively) and significantly greater number of patient were able to achieve straight leg raise on Post operative day 3 with significantly better range of motion in post operative day 3 and 5 in non-tourniquet group. Neither intraoperative blood loss nor drain nor calculated blood loss was significantly different. Functional outcome was similar in both groups on third month and sixth month.
Conclusion
There was no difference in functional outcome in two groups till 6 month with no radiolucency seen till 6 month. This study shows use of tourniquet related to increase thigh and limb pain and delay in rehabilitation in early post-operative period with no difference after 5 days has better intra-operative visuality and no risk of DVT and nerve palsy.
