Background: Tourniquets are commonly used in one-stage bilateral sequential total knee replacement surgeries to create the bloodless surgical field. It is commonly believed that the use of tourniquet decreases the operative time, improves the cementation and, therefore, improves fixation of prostheses. However, there are distinct disadvantages of using a thigh tourniquet in lower limb surgeries. In our institution, we have been performing one-stage bilateral sequential total knee replacement without the use of a tourniquet. We wish to present our study comparing two groups of patients with regards to post-operative thigh pain, thigh bruising, number of post operative dressings used, need of blood transfusion, duration of hospital stay, and thigh weakness by assessing straight leg raising test.
Materials and Methods: We prospectively evaluated thirty consecutive patients who underwent one-stage bilateral sequential total knee replacement. We divided the patients into two groups; group 1 who underwent one-stage bilateral sequential total knee replacement with a tourniquet (tourniquet group; n=15) and group 2 who underwent one-stage bilateral sequential total knee replacement without tourniquet (no tourniquet group; n=15).
Results: We looked at the following parameters in both groups and was statistically analysed: 1) Post-operative thigh pain, 2) Post-operative thigh bruising, 3) Straight leg raising test (SLRT), 4) Number of post-operative dressing change due to soakage, 5) How much blood transfusion is required, 6) Mean length of hospital stay. Conclusion: Our study showed that One-stage bilateral sequential total knee replacement without tourniquets are safe and there may be more advantages than previously thought.
