Tibial Tubercle Osteotomy, Tranexamic Acid

Brief summary

The purpose of the proposed study is to evaluate the effects of administering intravenous tranexamic acid (TXA) to patients undergoing high tibial osteotomy (HTO) and tibial tubercle osteotomy (TTO) to minimize hemarthrosis within the knee joint and post operative pain and swelling.

Detailed description

Not Provided

Interventions

DRUGTranexamic Acid (TXA)

One gram of intravenous tranexamic acid (TXA) will be administrated before tourniquet inflation and before closure of the incision, as 1 g has been shown to be a safe amount with minimal side effects

Secondary

MeasureTime frameDescription
Score on Visual Analogue Scale (VAS) for PainDay 1VAS will be used to report post-operative pain. A patient is asked to indicate his/her perceived pain intensity (most commonly) along a 10 mm horizontal line, and this rating is then measured from the left edge (=VAS score). The total score range is 0 (no pain) to 10 (worst pain imaginable); the higher the score, the worse the pain.
