Understanding the tibial plateau and its significance in knee stability is crucial for patients and healthcare providers alike. When a tibial plateau fracture occurs, especially those that involve displaced fragments, Open Reduction and Internal Fixation (ORIF) is often the recommended surgical intervention. The tibial plateau orif protocol encompasses a series of carefully planned steps aimed at achieving optimal healing, restoring knee function, and minimizing long-term complications. This article provides a detailed overview of the protocol, including preoperative considerations, surgical procedures, postoperative care, and rehabilitation strategies.

What is a Tibial Plateau Fracture?
A tibial plateau fracture involves a break in the upper part of the tibia (shinbone) that forms part of the knee joint. These fractures often result from high-energy trauma such as car accidents, falls from significant heights, sports injuries, or low-energy incidents in osteoporotic patients.
Types of Tibial Plateau Fractures
- Split fractures: Vertical or horizontal fractures dividing the plateau.
- Depressed fractures: Fragments are driven into the bone.
- T-shaped fractures: Combination of split and depression.
- Complex fractures: Multiple fragments involving both condyles.
Importance of Proper Treatment
If not appropriately managed, tibial plateau fractures can lead to:
- Post-traumatic osteoarthritis
- Knee instability
- Reduced range of motion
- Chronic pain
- Ligament injuries

Goals of the tibial plateau orif protocol
The primary objectives include:
- Achieving anatomical reduction of fracture fragments
- Restoring the joint surface congruity
- Providing stable fixation to allow early mobilization
- Preventing posttraumatic osteoarthritis
- Facilitating early range of motion exercises

The tibial plateau orif protocol: Step-by-Step Overview
1. Preoperative Preparation
- Patient positioning: Supine on a radiolucent table
- Anesthesia: General or spinal anesthesia
- Tourniquet application: To reduce bleeding during surgery
- Antibiotic prophylaxis: Administered prior to incision
2. Surgical Approach
Common approaches include:
- Lateral approach: For lateral plateau fractures
- Medial approach: For medial plateau fractures
- Dual approach: For complex bicondylar fractures
3. Fracture Reduction
- Visualization: Exposure of fracture site
- Reduction techniques:
- Manual manipulation under fluoroscopy
- Use of joysticks or K-wires for fragment manipulation
- Elevation of depressed fragments (via bone graft or substitute if necessary)
4. Fixation
- Implants used:
- Anatomical locking plates
- Screws for fragment stabilization
- Bone grafts or substitutes for depressed areas
- Procedure:
- Secure reduction with temporary K-wires
- Confirm alignment using intraoperative fluoroscopy
- Fixate with plates and screws ensuring stability
- Address soft tissue injuries if present
5. Soft Tissue Management
- Repair or manage associated ligament or meniscal injuries
- Ensure no undue tension on soft tissues
6. Closure
- Layered suturing of soft tissues
- Application of sterile dressing
- Placement of a sterile immobilizer or splint if needed

Postoperative Care and Initial Management
Immediate Postoperative Protocol
- Monitoring:
- Vascular and neurological assessments
- Pain control
- Prevention of complications (e.g., DVT prophylaxis)
- Immobilization:
- Usually a knee brace or posterior splint
- Elevation and Ice:
- To reduce swelling
- Early Mobilization:
- Initiate within pain limits as per surgeon’s instructions
Weight-Bearing Guidelines
- Typically, non-weight bearing for 6-8 weeks
- Progression to partial and then full weight-bearing based on radiographic evidence of healing
