Conditions

Knee Osteoarthritis

Brief summary

This multicenter clinical trial aims to investigate the exact effect of drainage use for osteoarthritis patients in total knee arthroplasty (TKA) on post-operative performance.

Detailed description

This is a multicenter,open-label randomized controlled trail. A total of 100 participants will receive same perioperative treatment schedule, and all surgeries will be carried out by the same surgeon. Among all the participants, 50 patients will be randomly assigned to the experiment group in which a drainage will be applied during the surgery, while another 50 patients will be randomly assigned to the control group without a drainage application in the surgery.Data on perioperative bleeding volume, swelling of lower extremities, pain score will be collected and analysed.

Interventions

PROCEDUREdrainage

Applying a drain tube during TKA procedure

PROCEDUREnon-drainage

No drain tube will be applied during TKA procedure

Design outcomes

Primary

Measure	Time frame	Description
The change of bleeding volume in perioperative period	before operation and one week after operation	The difference between baseline Hct collected before operation and Hct collected one week after operation

Secondary

Measure	Time frame	Description
Swelling of the lower extremities	one week after operation	perimeter of lower extremities before and after operation
Range of motion	one week after operation	Range of motion of the knee received operation
Pain	one week after operation	Use the Visual Analogue Scale to estimate the pain and its score ranges from 0 to 10. The higher the score is, the more severe pain the patient is feeling.
