Influence of Closed Suction Drainage After Total Knee Replacement.

Not Applicable
Conditions
Total Knee Replacement
Interventions
Procedure: Abstain of using a closed suction drainage
Procedure: Use of closed suction drainage following total knee arthroplasty
Registration Number
NCT03995160
Lead Sponsor
Medical University of Warsaw
Brief Summary

The aim of the study will be to compare functional outcomes, basic morphology results, number of blood transfusions, costs of hospitalization, and inflammation factors, following total knee replacement (with use of one type of endoprosthesis) comparing use of closed suction drainage (CSD). Use of closed suction drainage may have influence on patients functional outcome.

Detailed Description

Patients with primary knee osteoarthritis will be included in a randomized controlled trial and assigned to total knee arthroplasty with or without closed suction drainage. Subjects will be evaluated preoperatively, 1-day, 3-, 6- and 12-month postoperatively.

Change in morphology results will be measured by comparing preoperative and postoperative levels of haematocrite, haemoglobin, erythrocytes, and platelets.

Change in the number of blood transfusions will be measured by analyzing the number of needed transfusion of packed red blood cells in the postoperative period during stay in the hospital.

Change in levels of inflammation factors will be measured by analyzing the level of C-reactive protein in first and third day postoperatively.

Change in body temperature wille be measured daily by analyzing body temperature from day of the surgery until the day of discharge from the hospital

Presence of haematoma will be evaluated daily in the postoperative period by clinical examination.

Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Pain Score will be measured from baseline (can be measured anytime to a maximum of one month before surgery) 3,6 and 12 months post-operatively

Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Function Score will be measured from baseline (can be measured anytime to a maximum of one month before surgery) 3,6 and 12 months post-operatively

Costs of hospitalization will be measured by comparing cost of hospitalization between two analyzed groups

Primary Outcome Measures
NameTimeMethod
Change in erythrocytes levelsfrom baseline (can be measured anytime to a maximum of one month before surgery) to 1-day, 3,6 and 12 months post-operatively

Measuring results of erythrocytes (number/ml)

Change in haematocrite levelsfrom baseline (can be measured anytime to a maximum of one month before surgery) to 1-day, 3,6 and 12 months post-operatively

Measuring results of haematocrite (in percentage in 1 ml of blood sample)

Change in the number of blood transfusionsfrom baseline to the 1-,2-,3- days postoperatively

Measuring the number of needed transfusion of packed red blood cells in the postoperative period

Change in levels of inflammation factorsfrom baseline (can be measured anytime to a maximum of one month before surgery) to 1-day, 3,6 and 12 months post-operatively

Measuring the level of C-reactive protein

Change in haemoglobin levelsfrom baseline (can be measured anytime to a maximum of one month before surgery) to 1-day, 3,6 and 12 months post-operatively

Measuring results of haemoglobin (g/dL)

Change in platelets levelsfrom baseline (can be measured anytime to a maximum of one month before surgery) to 1-day, 3,6 and 12 months post-operatively

Measuring results of platelets (number/ml)

Secondary Outcome Measures
NameTimeMethod
Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Pain Score from baselinefrom baseline (can be measured anytime to a maximum of one month before surgery) 3,6 and 12 months post-operatively

The WOMAC Pain score is derived from a sub-section of the Knee injury and Osteoarthritis Outcome Score (KOOS) Knee Survey. The WOMAC Pain scores range from 0-100 with lower scores considered lower pain.

Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Function Score from baselinefrom baseline (can be measured anytime to a maximum of one month before surgery) 3,6 and 12 months post-operatively

The WOMAC Function score is derived from a sub-section of the Knee injury and Osteoarthritis Outcome Score (KOOS) Knee Survey. The WOMAC Function scores range from 0-100 with lower scores considered to have better function.

Change in body temperaturefrom baseline to the 1-,2-,3- days postoperatively

Measuring body temperature from day of the surgery to the hospital until the day of discharge from the hospital

Influence of using CSD on costs of hospitalizationfrom baseline to the one year postoperatively

Comparing cost of hospitalization between two analyzed groups
