Effects of tourniquet use on @entity121 function and XXXX in total knee arthroplasty.

@entity1 @entity571 @entity190 @entity4 @entity158 @entity121
PURPOSE: A pneumatic tourniquet is commonly used in total knee arthroplasty (TKA) to improve surgical field visualisation but may result in @entity121 muscle ischaemia. We performed this study to analyse the effect of the tourniquet on recovery following TKA. MATERIALS AND METHODS: A prospective randomised single-blinded trial was undertaken to examine the effect of the tourniquet on post-operative @entity158 , @entity4 , @entity190 , @entity121 function and outcome following TKA. Twenty @entity1 with @entity571 of the knee were randomised to tourniquet or no tourniquet groups. Quadriceps function was assessed using surface electromyography (EMG) during active knee extension. RESULTS: The no tourniquet group had significantly less @entity158 in the early post-operative period compared to the tourniquet group. There was no difference in Oxford knee score, range of motion, or thigh and knee @entity4 up to 12 months post-operatively. Quadriceps function, measured by surface EMG, was compromised for the first six months post-surgery by tourniquet use. The radiological cement mantle at the bone prosthesis interface at 12-month follow-up was not affected by the absence of a tourniquet. CONCLUSIONS: We believe that it is safe and beneficial for our @entity1 to routinely perform TKA without a tourniquet.
