Method of measurement: Based on cbc test and in gr/dl.;Body size changes. Timepoint: It is measured before surgery and then on days 1, 7, 14, 60. Method of measurement: In 2 places, 5 cm above the medial malleolus and 10 cm above the superior patella, the limb circumference is measured.;Knee range of motion. Timepoint: It is measured before surgery and then on days 1, 7, 14, 60. Method of measurement: in degrees and using goniometr.;Knee pain. Timepoint: It is measured before surgery and then on days 1, 7, 14, 60. Method of measurement: Based on the Visual Analogue Scale.;Strength of knee extensor and flexor muscles. Timepoint: It is measured before surgery and then on days 1, 7, 14, 60. Method of measurement: Clinical examination of muscle strength.;Post operation complications. Timepoint: Day 1,7,14,60. Method of measurement: Presence or absence of dvt/pte/bleeding/infection. | — |

| Measure | Time frame |
|---|---|
| Comparing the amount of cement penetration around the prosthesis in patients who undergo TKA surgery with and without the use of a tourniquet. Timepoint: 60 days after surgery, AP and LAT radiographs of the knee were taken, and based on the criteria of the Knee Society Radiographic Evaluation System, cement penetration was calculated in millimeters. Method of measurement: According to the Knee Society Radiographic Evaluation System in AP/Lat radiographs of the knee. | — |
