Study Overview
Brief Summary
Tourniquet use during total knee arthroplasty (TKA) improves visibility and reduces intraoperative blood loss. However, tourniquet use may also have a negative impact on early recovery of muscle strength and lower extremity function after TKA.Seventy Patients are involved in this study and were divided into two groups; Group A (35) patients were treated with TKA with pneumatic thigh tourniquet. Group B (35) patients were treated with TKA without tourniquet. All patients were suffering from severe knee osteoarthritis and they failed to respond to conservative treatment so they are candidates for primary TKA. The two groups are matched related to age and gender. Selection of patients into two groups done randomly with regard of odd number for group A and even number for group B
Detailed Description
This study started on March 2016 and ends on October 2018. Seventy Patients are involved in this study and were divided into two groups; Group A (35) patients were treated with TKA with pneumatic thigh tourniquet. Group B (35) patients were treated with TKA without tourniquet. All patients were suffering from severe knee osteoarthritis and they failed to respond to conservative treatment so they are candidates for primary TKA. The two groups are matched related to age and gender. Selection of patients into two groups done randomly with regard of odd number for group A and even number for group B. All patients were followed for a period of two weeks until removal of skin sutures for the following parameters:
Amount of blood transfusion done at and after surgery. Amount of blood drained postoperatively through suction drain. Occurrence of postoperative wound hematoma. VAS (Visual analogue score) for thigh pain at 1st day and (2) weeks postoperatively.
Clinical DVT.

Arms & Interventions
TKA with tourniquet
This group was treated by TKA with the use of tourniquet
Intervention: Tourniquet use (Procedure)
TKA without tourniquet
This group was treated by TKA without tourniquet
Intervention: Tourniquet use (Procedure)
Outcomes
Primary Outcomes
Visual Analogue score for thigh pain
Time Frame: The VAS for thigh pain was measured in the day 14 after operation
This is measurement of the degree of thigh pain after operation which range from zero to 10
Secondary Outcomes
No secondary outcomes reported
