Brief Summary:
The investigators will include patients who will be schedule for total knee arthroplasty with a diagnosis of osteoarthritis. The patients will be divided in two groups. In both groups a verbal and clear detailed information will be given on the intraoperative approach. The first group will receive topical tranexamic acid and the second group topical platelet rich plasma; both in the surgical site. Both groups will be assessed before and after the intervention with laboratory results (hemoglobin, hematocrit levels) and drainage drain.

Arm Intervention/treatment
Experimental: Group 1 Tranexamic acid

A dosis of 2 gr of tranexamic acid (1000mg/10ml X-GEN pharmaceuticals inc.) diluted in 80ml of physiologic solution and will be divided in two applications.

First application: 40ml of the solution previously prepared is applied over the surgical site and it will be left for five minutes then drained out completely by suction.

Second application: The rest of 40ml of solution previously prepared is applied after placing the final TKR components (femoral, tibial and patellar), over the surgical site and leaving it without draining it by suction.

Drug: Group 1 Tranexamic Acid
2 gr of tranexamic acid will be applied on the surgical site.
Other Name: Topic Tranexamic Acid

Active Comparator: Group 2 Platelet rich plasma

A final volumen of 16 ml of platelet rich plasma is obtained from the forearm vein of the patient and will be divided in two applications.

First application: 8 ml of PRP are applied over the surgical site and are left for five minutes then drained out completely by suction.

Second application: The rest of the 8 ml are applied after placing the final TKR cemented components (femoral, tibial and patellar), over the surgical site and leaving it without draining.

Biological: Group 2 Platelet rich plasma
16ml of platelet rich plasma will be applied of the surgical site
Other Name: PRP




Primary Outcome Measures :
  1. Therapeutic Effect on Hemoglobin Level [ Time Frame: up to 3rd day post operative (Baseline, 24, 48 and 72hrs) ]
    The blood test will be taken at 6am every day. Using the same laboratory parameters.


Secondary Outcome Measures :
  1. Therapeutic Effect on Hematocrit Level [ Time Frame: up to 3rd day post operative (Baseline, 24, 48 and 72hrs) ]
    The blood test will be taken at 6am every day. Using the same laboratory parameters.

  2. Therapeutic Effect on Drainage Quantification [ Time Frame: up to 2nd day post operative (24 and 48 hrs) ]
    The blood quantification will be taken at 6am every day.
