About the trial
What the trial wants to find out
This study aims to evaluate whether the timing of Hemovac drain removal affects early clinical outcomes after primary total knee arthroplasty (TKA). Hemovac drains are commonly used after TKA to reduce postoperative bleeding and swelling; however, the optimal timing for drain removal remains controversial.
Read full original descriptionShow less
In this prospective observational cohort study, patients undergoing primary TKA for knee osteoarthritis will be divided into two groups according to routine clinical practice: those whose drain is removed before the first postoperative rehabilitation session and those whose drain is removed after the first rehabilitation session.
The primary outcomes include the rate of postoperative hemarthrosis, early postoperative complications, and length of hospital stay. Secondary outcomes include postoperative pain levels and functional outcomes. The results of this study may help optimize postoperative management strategies following total knee arthroplasty.
The 2 groups in the trial
- Early Drain Removal (Goup 1)
Patients whose Hemovac drain is removed before the first postoperative rehabilitation session as part of routine clinical practice.
- Late Drain Removal (Group 2)
Patients whose Hemovac drain is removed after completion of the first postoperative rehabilitation session as part of routine clinical practice.
