Effect of Timing of Hemovac Drain Removal on Early Outcomes After Total Knee Arthroplasty
Effect of Timing of Hemovac Drain Removal on Early Outcomes After Total Knee Arthroplasty
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.
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.
Total knee arthroplasty (TKA) is a widely performed surgical procedure for the treatment of advanced knee osteoarthritis. Postoperative management often includes the use of closed suction drains, such as Hemovac systems, to reduce hematoma formation and wound complications. However, the necessity and optimal timing of drain removal remain subjects of debate.
This prospective observational cohort study is designed to compare early clinical outcomes associated with two different timings of Hemovac drain removal following primary TKA. Patients who undergo primary TKA at a single tertiary care center will be enrolled prospectively. According to routine postoperative practice, patients will be allocated into two groups: drain removal before the first postoperative rehabilitation session or drain removal after completion of the first rehabilitation session.
All patients will receive standardized surgical techniques, anesthesia protocols, postoperative care, and rehabilitation programs. Data will be collected prospectively. Primary outcomes include postoperative hemarthrosis, early postoperative complications, and length of hospital stay. Secondary outcomes include postoperative pain intensity and functional outcome measures.
This study aims to provide evidence to guide clinical decision-making regarding postoperative drain management in patients undergoing total knee arthroplasty.
