Abstract

Background: A safe, cost-effective operation that improves the quality of life for those with advanced knee arthritis is total knee arthroplasty (TKA). Rheumatoid arthritis and osteoarthritis, which are characterized by pain, deformity, and instability, are the most common causes of total knee replacement. Significant blood loss happens during the TKA operation, which may necessitate a blood transfusion. A gauge of blood loss is the volume of blood that accumulates in drains. In total knee replacement (TKR) surgery, orthopedic surgeons typically use a tourniquet to reduce bleeding and improve surgical visibility. Nonetheless, questions have been raised about how well a tourniquet works to stop blood loss.


Objective: To determine the variables affecting increased blood loss during total knee replacement surgery.


Study design: A retrospective study


Place and Duration: This study was done at, Zimri Orthopedic Hospital Islamabad Pakistan for the period of one year.


Methodology: There were 40 patients in each group, for a total of 80 patients engaged in the study. Both groups had their blood loss assessed; the case group had a tourniquet applied during the procedure, while the control group had surgery performed without tourniquet. People with persistent osteoarthritis, of both genders, diagnosed between the ages of 40 and 70 years, were included in the study.


Results: A total of 80 patients were enrolled for this research. All of them were equally divided into 2 groups having 40 patients each. One was a tourniquet group while the other was a non-tourniquet group. The average age, height, and weight of the patients in both groups did not differ significantly. However, at a significance threshold of 0.01, a significant difference in the mean blood loss between the two groups was found. The tourniquet group lost less blood than the control group, which showed somewhat greater amounts.


Conclusion: Using a tourniquet during total knee replacement (TKR) is advised since it is linked to lower blood loss, shorter operating times, and fewer instances of blood transfusions.
