Eligibility
Inclusion criteria
Inclusion criteria: Participants diagnosed with primary or secondary arthrosis in at least one knee joint with clinical indication (refractory pain, flexion-extension range of motion restriction and / or joint instability) and radiological (knee osteoarthritis grading systems): Alback, modified by Keys III and / or kellgren-Lawrence II) for total knee arthroplasty surgery.
Exclusion criteria
Exclusion criteria: Have a diagnosis of mild primary arthrosis of the knee (Alback, modified by Keys less than III and / oukellgren-LawrenceI) without indication for substitute surgery; have hematological diseases; inflammatory arthropathies be a candidate for revision total knee arthroplasty (second total knee arthroplasty); being medicated with anticoagulant; have post traumatic knee arthrosis with previous synthesis surgeries; have indication of bilateral total knee arthroplasty at the same surgical time; besides the patients who, despite being selected, had insufficient data collection to evaluate the outcomes.
Design outcomes
Primary
| Measure | Time frame |

| Expected Primary Outcome: The suction drain used within the first 24 hours postoperative of total knee arthroplasty does not change the hematimetric indices (hemoglobin and hematocrit) when compared with not using this device also within the first 24 hours postoperative of surrogate surgery. of the knee joint. Evaluation of Expected Outcome: Participants in the experimental group (24-hour drainage use after total knee arthroplasty surgery) and control group (without drainage) will undergo preoperative measurement of hematimetric indices (hemoglobin and hematocrit). ) one week prior to the date of surgery, and 24 hours after the end of surgery, so that the variation of hematimetric data (pre vs. postoperative) is evaluated. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcomes evaluated: pain, wound infection, modified functional outpatient categorization (MFAC) and length of stay. Expected secondary outcomes and their assessments: - Pain: It is expected that the suction drain used in the postoperative period of total knee arthroplasty surgery does not change the pain levels evaluated by the visual analogue pain scale (VAS) when compared to the non-use of the suction drain. in the postoperative period of total knee arthroplasty surgery. For this evaluation, VAS will be applied to participants in the immediate preoperative period (day of surgery), 1st, 4th, 10th and 30th postoperative days. The scale used will be printed and colored, ranging from 0 to 10 points, associating Arabic numerals with engravings of different faces according to the numbering corresponding to the degree of pain perceived by the patient.;- Surgical wound infection: It is expected that the suction drain used in the postoperative period of total knee arthroplasty surgery does not change the incidence of surgical site infection when compared to the non-use of the suction drain postoperatively in the surgical procedure. total knee arthroplasty. For the evaluation of the infection periodic evaluations will be performed in search of the appearance of clinical signs of infection in the arthroplasty site on the 4th, 10th and 30th postoperative days. Infection will be considered if 1 or more of the following signs are present: erythema associated with necrosis or suffering of edges, fistula, pus, or the presence of persistent drainage of discharge.;- Modified Functional Outpatient Categorization (MFAC): It is expected that the suction drain used in the postoperative period of total knee arthroplasty surgery does not change the participant's classification in relation to their “modified functional outpatient categorization” (MFAC) when compared to non-use of suction drain in the postoperative period of total knee arthroplasty surgery.For this outcome, the | — |
