Abstract | Introduction: Application of tourniquet in total knee arthroplasty is postulated to improve cement penetration, but its effect
is not proven. Tourniquet also affect rehabilitation due to muscle inflammation and pain. We aim to evaluate the effect of
tourniquet on cement penetration and long-term functional outcome. We hypothesize that the effect is insignificant.
Methodology: This is a case-controlled study involving patients who underwent TKA between 2014-2017 in a public
hospital. Patients were divided into tourniquet and non-tourniquet group. Surgeon, surgical technique and implant types are
controlled. X-ray measurements of cementation depth and presence of radiolucent lines were recorded. Pre and
post-operative functional scores KSKS and KSFA were compared. Analysis of covariance (ANCOVA) was used for statistical
analysis.
Results and Analysis: 76 patients were included. X-Ray measurements of cement depth showed no significant difference
between the two groups at day 1 and 2-years (p=0.219-0.668). There was no significant difference in the presence of RLL
(p=0.187-0.868). There was however better KSKS (93.12+-3.73 vs 89.97, P=0.014) and KSFA (76.80+-20.46 vs 62.07+-13.40,
P=0.005) in the tourniquet group.
Discussion and Conclusion: There is no benefit of tourniquet usage on cementation in TKA. Tourniquet group had better
functional outcome, which may be accountable to better pre-op parameters such as range of motion in the tourniquet
group. A better study design is needed for conclusive evidence. |
