Introduction
Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are among the most successful orthopedic procedures for restoring mobility and improving quality of life in patients with advanced joint degeneration.
However, postoperative management after joint replacement surgery continues to evolve. One long-standing question remains controversial among orthopedic surgeons:
Should routine surgical drains be used after primary total knee and total hip arthroplasty?
For decades, surgeons commonly placed drainage tubes after joint replacement procedures with the belief that removing postoperative blood accumulation could reduce hematoma formation, wound complications, and infection risk.
However, with advances in modern arthroplasty techniques—including improved hemostasis, tranexamic acid (TXA) protocols, minimally invasive approaches, and enhanced postoperative rehabilitation—the necessity of routine drainage has been increasingly questioned.
Current evidence suggests that routine surgical drain placement is not recommended for uncomplicated primary total knee arthroplasty and total hip arthroplasty.
A recent expert consensus showed that:
83.52% of experts recommended against routine drain use
12.91% supported drain placement
3.59% abstained
The evidence level supporting this recommendation is considered high.
This article reviews the history, current evidence, potential disadvantages, and practical recommendations regarding surgical drains after primary joint replacement surgery.
Key Takeaways
Routine surgical drains are not recommended after uncomplicated primary TKA and THA.
High-level evidence from randomized controlled trials and systematic reviews shows limited clinical benefit.
Drain placement may increase total blood loss and transfusion requirements.
Current infection prevention strategies rely more on meticulous hemostasis, antibiotics, TXA use, and modern wound management.
Selective drain use may still be considered in complex cases with increased bleeding risk.
The use of surgical drainage systems dates back to the mid-20th century.
After major orthopedic procedures, surgeons were concerned about postoperative blood accumulation within the surgical site.
The theoretical benefits of drainage included:
Removing accumulated blood and fluid
Preventing hematoma formation
Reducing wound tension
Improving soft tissue healing
Lowering infection risk
Historically, postoperative hematoma was considered an important contributor to surgical site infection because accumulated blood could serve as a medium for bacterial growth.
Therefore, placing a drainage tube became a routine step after many orthopedic operations, especially:
Total knee arthroplasty
Total hip arthroplasty
Trauma fixation procedures
Early studies suggested that drainage might reduce infection risk, reinforcing its widespread adoption.
However, as surgical techniques improved, the clinical value of routine drainage became increasingly uncertain.
Over the past several decades, orthopedic surgery has undergone significant improvements:
Modern surgeons can better control bleeding through:
Precise soft tissue handling
Electrocautery techniques
Improved implant instrumentation
Careful vessel management
The widespread adoption of TXA has dramatically reduced perioperative blood loss in arthroplasty patients.
Compared with previous decades, patients today generally experience:
Less postoperative bleeding
Lower transfusion rates
Faster recovery
Modern arthroplasty pathways emphasize:
Early mobilization
Reduced unnecessary devices
Shorter hospitalization
Patient comfort
Within this new clinical environment, routine drainage has become less attractive because its theoretical benefits have not consistently translated into improved outcomes.
A large number of high-quality studies have evaluated the effectiveness of postoperative drainage.
Evidence reviews have identified:
38 Level I evidence studies
31 randomized controlled trials
7 systematic reviews
Overall, these studies indicate:
Routine drain placement does not provide significant advantages in uncomplicated primary joint replacement surgery.
The available evidence suggests that drains:
Do not clearly reduce infection rates
Do not consistently improve wound healing
Do not improve functional recovery
Therefore, routine drainage has gradually moved away from standard practice in many orthopedic centers.
One important concern regarding drains is that they may paradoxically increase postoperative blood loss.
Several studies have demonstrated:
Higher total blood loss in drain groups
Increased hidden blood loss calculated through hemoglobin balance methods
Although not every study has reached the same conclusion, the overall trend suggests that drainage may allow continued postoperative bleeding rather than preventing it.
Among studies reporting transfusion outcomes:
Several demonstrated increased transfusion requirements among patients receiving drains.
This may occur because:
The drainage system continuously removes blood from the surgical site.
Blood loss estimation becomes underestimated.
Hemoglobin reduction may become clinically significant.
Reducing unnecessary blood loss is especially important in elderly patients and those with cardiovascular comorbidities.
One of the main historical arguments for drainage was infection prevention.
However, modern studies have not confirmed a consistent protective effect.
Research findings remain conflicting:
Some studies suggest:
No drain → higher infection risk
Other studies report:
Drain use → increased infection risk
Possible explanations include:
Different surgical protocols
Different antibiotic strategies
Different patient populations
Variations in drain duration
Currently, there is insufficient evidence to recommend drains as an infection prevention strategy.
Studies evaluating:
Persistent drainage
Dressing changes
Wound healing problems
have shown inconsistent results.
Some reports favor drainage, while others demonstrate no difference or even worse outcomes.
Therefore, routine drain placement cannot be justified solely for wound management.
The relationship between drains and pain remains unclear.
Some studies report increased discomfort due to:
Drain irritation
Limited mobility
Need for removal procedures
However, other studies have found no significant difference.
Because pain evaluation methods vary considerably, current evidence remains inconclusive.
Although uncommon, surgical drains may introduce additional problems:
Rare cases have been reported where:
The drain becomes trapped during wound closure
Additional procedures are required for removal
Drain management requires:
Monitoring output
Recording volume
Maintaining sterile handling
Removal procedures
These factors increase healthcare workload and cost.
A drain represents another foreign pathway between the surgical environment and external surroundings, theoretically increasing contamination risk.
Although routine use is not recommended, selective drainage may still have a role in specific situations.
Potential indications include:
Examples:
Revision THA
Revision TKA
Extensive soft tissue reconstruction
Including patients with:
Coagulation disorders
Anticoagulant therapy
Difficult intraoperative bleeding control
Situations where significant postoperative fluid accumulation is expected.
The decision should always be individualized according to patient factors and intraoperative findings.
As routine drain placement becomes less common, orthopedic surgeons have developed more effective strategies to control bleeding, prevent hematoma formation, and improve wound healing after joint replacement surgery.
Modern arthroplasty management focuses on preventing excessive bleeding rather than removing blood after it accumulates.
The main strategies include:
One of the most important factors determining postoperative bleeding is the quality of intraoperative hemostasis.
Experienced surgeons minimize blood loss through:
Careful surgical dissection
Identification and coagulation of bleeding vessels
Avoidance of unnecessary soft tissue injury
Proper management of bone surfaces
Controlled release of tourniquet before closure
Unlike traditional concepts that relied on postoperative drainage, modern techniques emphasize preventing bleeding at its source.
The introduction of tranexamic acid has significantly changed perioperative blood management in orthopedic surgery.
TXA works by inhibiting fibrinolysis, helping stabilize blood clots and reducing excessive postoperative bleeding.
Multiple studies have demonstrated that TXA can:
Reduce total blood loss
Decrease hemoglobin reduction
Lower transfusion requirements
Improve recovery efficiency
For modern TKA and THA, TXA has become a key component of enhanced recovery protocols.
Because bleeding control is improved pharmacologically, the theoretical necessity of routine drainage has further declined.
Soft tissue closure plays an essential role in preventing postoperative wound problems.
Current techniques include:
Proper closure of:
Joint capsule
Fascia
Subcutaneous tissue
Skin
helps eliminate dead space and reduces fluid accumulation.
Modern absorbable and high-strength sutures provide:
Reliable tissue approximation
Reduced inflammatory reaction
Better wound stability
Modern wound dressings provide:
Protection from external contamination
Management of minor postoperative fluid leakage
Improved patient comfort
Clinical Outcome | Drain Use | No Drain |
|---|---|---|
Blood loss | May increase total blood loss | Usually lower |
Blood transfusion | Possible increased requirement | Reduced requirement |
Infection rate | No proven advantage | Similar or lower |
Wound complications | Conflicting evidence | Similar outcomes |
Pain | Possible drain-related discomfort | Often more comfortable |
Nursing burden | Higher | Lower |
Hospital efficiency | May delay recovery | Supports enhanced recovery |
Current evidence suggests that avoiding routine drainage does not compromise patient safety in uncomplicated primary arthroplasty.
Based on current evidence and expert consensus, the following principles can guide clinical practice:
For standard primary:
Total knee arthroplasty
Total hip arthroplasty
without unusual bleeding risks:
Routine surgical drainage is not recommended.
The key components include:
Preoperative risk assessment
Appropriate TXA administration
Accurate surgical technique
Effective hemostasis
Proper wound closure
Preventing blood accumulation is more effective than removing it afterward.
Although routine drainage is unnecessary, surgeons should consider patient-specific factors.
A drain may still be reasonable when:
Extensive tissue dissection is required
Unexpected bleeding occurs
Revision surgery creates large dead spaces
The surgeon has concerns regarding postoperative fluid accumulation
Clinical judgment remains essential.
In many modern orthopedic centers, routine drainage after primary total knee arthroplasty is no longer standard practice.
Current evidence does not show clear benefits in preventing infection or improving recovery.
Many surgeons now perform TKA without placing drains.
Current research does not demonstrate that avoiding drains increases infection rates after uncomplicated primary total hip arthroplasty.
Modern infection prevention depends mainly on:
Strict sterile technique
Antibiotic prophylaxis
Laminar airflow systems where applicable
Proper surgical technique
Optimized patient factors
The main reasons include:
Lack of strong evidence supporting routine benefit
Potential increase in blood loss
Possible increased transfusion requirements
Additional discomfort and management burden
Development of better bleeding-control strategies
Yes, but in most primary arthroplasty cases, the body can naturally manage small amounts of postoperative fluid.
With:
Proper hemostasis
TXA use
Modern closure techniques
clinically significant hematoma formation is uncommon.
Yes.
Drain placement may be considered in:
Revision arthroplasty
Severe intraoperative bleeding
Complex reconstruction
Patients with increased bleeding risk
However, it should be based on individual assessment rather than routine use.
The history of surgical drains reflects a broader principle in orthopedic surgery:
More devices do not always mean better outcomes.
Modern joint replacement has shifted from traditional intervention-based care toward evidence-based minimal intervention.
Future arthroplasty management will likely continue focusing on:
Blood conservation
Minimally invasive techniques
Enhanced recovery pathways
Patient-specific protocols
Reduced unnecessary devices
The goal is not simply preventing complications, but achieving faster recovery with fewer barriers for patients.
Current evidence indicates that routine surgical drain placement is not necessary after uncomplicated primary total knee arthroplasty and total hip arthroplasty.
Although drains were historically used to prevent hematoma and infection, modern research shows limited clinical benefits and highlights potential disadvantages, including:
Increased blood loss
Higher transfusion requirements
Additional discomfort
Increased healthcare workload
Today, successful arthroplasty outcomes depend more on:
Precise surgical technique
Effective hemostasis
Tranexamic acid protocols
Proper wound closure
Enhanced rehabilitation pathways
For most primary TKA and THA procedures, avoiding routine drains represents an evidence-based approach aligned with modern orthopedic practice.
However, selective drain use may still be appropriate in complex or high-risk situations when individualized clinical judgment supports its necessity.
