Understanding the appropriate protocol for open reduction and internal fixation (ORIF) of tibial plateau fractures is crucial for orthopedic surgeons, residents, and patients alike. Proper adherence to established procedures ensures optimal fracture healing, restores knee joint stability, and minimizes complications. This article offers an in-depth overview of the tibial plateau fracture ORIF protocol, covering preoperative assessment, surgical techniques, postoperative management, and rehabilitation strategies.
Introduction to Tibial Plateau Fractures
Tibial plateau fractures involve the articular surface of the proximal tibia, often resulting from high-energy trauma such as vehicular accidents or falls from height, or low-energy injuries in osteoporotic bones. These fractures can compromise knee stability, alignment, and function, necessitating precise surgical intervention.
Preoperative Assessment and Planning
A thorough preoperative evaluation lays the foundation for successful ORIF. It involves clinical examination, imaging, and planning.
Clinical Examination
- Assess neurovascular status of the affected limb
- Evaluate soft tissue condition, swelling, and skin integrity
- Identify associated injuries (ligamentous, meniscal, neurovascular)
Imaging Studies
- Plain Radiographs: Anteroposterior (AP), lateral, and oblique views to classify the fracture (e.g., Schatzker classification)
- Computed Tomography (CT) Scans: Detailed assessment of fracture pattern, depression, comminution, and articular surface involvement
- Magnetic Resonance Imaging (MRI): Optional for soft tissue injuries, ligamentous, or meniscal tears
Preoperative Planning
- Determine the fracture type and complexity
- Decide on surgical approach (anterolateral, posteromedial, or dual approach)
- Prepare for possible soft tissue management
- Select appropriate implants (plates, screws, locking systems)
Surgical Technique and Protocol
The goal of ORIF is anatomic reduction of articular surfaces, stable fixation, and early mobilization. The surgical protocol involves patient positioning, anesthesia, approach selection, fracture reduction, fixation, and intraoperative assessment.
Patient Positioning and Anesthesia
- Position: Supine on a radiolucent table with a radiolucent bump under the ipsilateral buttock for lateral approaches; prone or supine depending on approach
- Anesthesia: General or spinal anesthesia, based on patient factors and surgeon preference
- Tourniquet: Applied for blood control, inflated as needed
Approach Selection
- Anterolateral Approach: For lateral plateau fractures
- Posteromedial Approach: For medial or posteromedial fragments
- Dual Approaches: When fracture involves both medial and lateral condyles or complex patterns
Fracture Reduction
- Carefully expose the fracture site
- Clear hematoma and debris
- Use reduction tools (e.g., clamps, joy-sticks)
- Achieve anatomic articular surface restoration
- Confirm reduction with intraoperative fluoroscopy
Fixation Techniques
- Plate Selection: L-shaped, T-shaped, or precontoured locking plates
- Screw Fixation: Screws placed perpendicular to fracture line for optimal stability
- Bone Grafting: Consider in cases with depression or cancellous voids
- Intraoperative Imaging: Fluoroscopy to verify reduction and hardware placement
Intraoperative Assessment
- Confirm articular congruency
- Ensure stable fixation
- Check limb alignment and soft tissue status
Postoperative Management Protocol
Postoperative care aims to promote healing, prevent complications, and restore knee function.
Immediate Postoperative Care
- Monitoring: Neurovascular status, pain control
- Immobilization: Knee immobilizer or brace as needed
- Pain Management: NSAIDs, opioids if necessary
- Antibiotics: Prophylactic as per institutional protocol
- Thromboprophylaxis: Low molecular weight heparin or aspirin
Early Mobilization and Weight-Bearing
- Typically, passive and active range of motion exercises commence within 1-3 days
- Non-weight bearing or partial weight bearing for 6-12 weeks, depending on fracture stability and fixation quality
- Gradual progression to full weight-bearing as radiographic healing is evident
Wound Care and Soft Tissue Management
- Regular inspection for signs of infection or wound dehiscence
- Drain removal if used
- Keep incision clean and dry
Monitoring Healing Progress
- Serial radiographs to assess fracture healing
- Clinical evaluation of knee stability, range of motion, and pain levels
Rehabilitation and Functional Recovery
A structured rehabilitation program is critical for restoring knee function and preventing stiffness.
Rehabilitation Phases
- Immobilization Phase (0-2 weeks): Focus on pain control, edema reduction, and gentle range of motion exercises
- Mobilization Phase (2-6 weeks): Progressive increase in knee flexion and extension, muscle strengthening
- Strengthening Phase (6-12 weeks): Resistance exercises, gait training, balance activities
- Return to Activities (>12 weeks): Gradual resumption of daily activities and sports, tailored to healing progression
Key Considerations in Rehabilitation
- Avoid excessive joint loading early on
- Maintain a balance between mobilization and protection
- Address soft tissue and ligamentous injuries if present
- Regular physiotherapy supervision
Potential Complications and Their Management
Awareness of possible complications enables early detection and intervention.
Common Complications
- Infection: Managed with antibiotics, wound care, or surgical washout
2. Nonunion or Malunion: May require revision fixation or osteotomy
3. Posttraumatic Osteoarthritis: Long-term management with conservative measures or total knee arthroplasty
4. Soft tissue problems: Wound dehiscence, necrosis
5. Hardware failure: May necessitate removal or revision surgery
Summary and Best Practices
Adhering to a structured tibial plateau fracture ORIF protocol involves meticulous preoperative planning, precise surgical technique, and comprehensive postoperative care. The primary goals are anatomic reduction, stable fixation, early mobilization, and functional recovery. Proper soft tissue management, vigilant monitoring for complications, and tailored rehabilitation are essential for optimal outcomes.
Best practices include:
- Thorough imaging and classification
- Choosing the appropriate surgical approach based on fracture pattern
- Ensuring stable hardware fixation
- Initiating early, controlled mobilization
- Educating patients about activity modifications and rehabilitation protocols
Implementing these principles within the ORIF protocol significantly improves healing rates, reduces complications, and restores knee function effectively.

Frequently Asked Questions
What is the typical ORIF protocol for tibial plateau fractures?
The ORIF protocol for tibial plateau fractures generally involves preoperative imaging, surgical fixation with plates and screws to restore joint congruity, followed by a structured postoperative rehabilitation program emphasizing early mobilization and weight-bearing as tolerated.
How soon can patients start weight-bearing after tibial plateau ORIF surgery?
Weight-bearing typically begins based on fracture stability and surgeon recommendation, often starting with partial weight-bearing around 6-12 weeks postoperatively, and progressing to full weight-bearing as healing permits, usually around 12-16 weeks.
What are common complications associated with tibial plateau ORIF procedures?
Common complications include infection, hardware failure, nonunion or malunion, post-traumatic osteoarthritis, and compartment syndrome. Proper surgical technique and postoperative care are essential to minimize these risks.
What imaging modalities are used to follow up after tibial plateau ORIF?
Postoperative follow-up typically involves standard radiographs to assess fracture healing and hardware position. In some cases, CT scans may be used for detailed evaluation of fracture reduction and joint surface congruity.
Are there specific rehabilitation protocols recommended after tibial plateau ORIF?
Yes, rehabilitation usually includes initial immobilization, followed by gradual range-of-motion exercises, strengthening, and functional training. The protocol is tailored based on fracture type, fixation stability, and patient progress.
What factors influence the success of the tibial plateau ORIF protocol?
Factors include fracture severity and pattern, quality of surgical fixation, patient age and health, adherence to rehabilitation, and management of comorbidities. Proper surgical technique and postoperative care are critical for optimal outcomes.
