Tibial cement mantle thickness is not affected by tourniquetless total knee arthroplasty when performed with tranexamic acid.

Tourniquet use in primary TKA results in decreased blood loss and less change in pre-operative vs post-operative haemoglobin and hematocrit levels. However, with the use of TXA, not using a tourniquet resulted in similar cement mantle penetration around the tibial component as with a tourniquet.
