Tibial Plateau Fractures


Lateral tibial plateau fracture

Tibial plateau fractures are complex injuries of the knee. The tibial plateau is one of the most critical load-bearing areas in the human body. Early detection and appropriate treatment of these fractures are essential in minimizing patient's disability in range of movement, stability and reducing the risk of documented complications.[1][2]

The fractures are classified according the Schatzker classification system. It divides tibial plateau fractures into six types:
• Schatzker I: lateral tibial plateau fracture without depression
• Schatzker II: lateral tibial plateau fracture with depression
• Schatzker III: compression fracture of the lateral (IIIa) or central (IIIb) tibial plateau
• Schatzker IV: medial tibial plateau fracture
• Schatzker V: bicondylar tibial plateau facture
• Schatzker VI: tibial plateau fracture with diaphyseal discontinuity[3][1]

A type I fracture is a wedge-shaped pure cleavage fracture of the lateral tibial plateau, with a displacement or depression less than 4mm. They are caused by the lateral femoral condyle being driven into the articular surface of the tibial plateau.[3]

Type II is a fracture with a combined cleavage and compression of the lateral tibial plateau, a type I fracture with a depressed component. There is a depression greater than 4mm.[3]

A Schatzker type III fracture is a pure compression fracture of the lateral tibial plateau in which the articular surface of the tibial plateau is depressed and driven into the lateral tibial metaphysis by axial forces. Type III fractures are divided into two subgroups: those with lateral depression (type IIIA) and those with central depression (type IIIB).[3]

Type IV is a medial tibial plateau fracture with a split or depressed component. These fractures occur as a result of varus forces combined with axial loading in a hyperflexed knee. Type IV fractures have the worst prognosis.[3]

Type V fracture consists of a wedge fracture of the medial and lateral tibial plateau, often with an inverted “Y” appearance. Articular depression is typically seen in the lateral plateau and might be associated with a fracture of the intercondylar eminence.[3]

Type VI is a bicondylar fracture with a dislocation of the metaphysis from the diaphysis.This pattern results from high-energy trauma and diverse combinations of forces.[1] [3]

The first three types are mostly the result of low energy injury, the three others of high energy injury. The magnitude of the force determined the degree of fragmentation and the degree of displacement.
Tibial plateau fractures are often associated with anterior cruciate ligament, collateral ligaments (MCL and/or LCL), menisci and articular cartilage injuries[3]


Clinically Relevant Anatomy

The proximal end of the tibia terminates in a broad, flat region called the tibial plateau.The intercondylar eminence runs down the midline of the plateau, seperating the medial and lateral condyles of the tibia. The two condyles form a flat, broad surface for articulation with medial and lateral condyles of the femur.[5]

Soft tissues of the knee can also be effected in tibial plateau fractures see knee for more details.

Epidemiology /Etiology 

Tibial plateau fractures are typically caused by a strong force on the lower leg with the leg in varus or valgus position, or simultaneous vertical stress and flexion of the knee.

Commonly seen in road traffic accidents, sports accidents with a high velocity such as skiing, horse riding and certain water sports.[6]

Due to the nature of injury soft tissue trauma is likely such as ligament rupture and needs to be considered when managing.[7]

Characteristics/Clinical Presentation

  • Swelling
  • Inability to weight bear
  • Bruising
  • Reduced knee range of movement (ROM)
  • History of trauma[1]
  • Pain

Differential Diagnosis

Tibial plateau fractures are common intra-atricular injury for which CT-scans are routinely used for pre-operative planning to rule out other pathology.[8] Approximately 50% of the knees with closed tibial plateau fractures have injuries of the menisci and cruciate ligaments that usually require surgical repair.[9]

Diagnostic Procedures 

Radiographic evaluation of these fractures involves four views: anteroposterior, lateral, internal oblique and external oblique. Computed tomography (CT) is of great value for determining the location and magnitude of the joint depression, however MRI has been shown to classify and assist management of the fracture best.[3][10]

Between Schatzker I and II there is not a clear visible difference on X ray.[3]

When there is a presumption of damage of the soft tissue, an MRI scan must be done[1]

Outcome Measures

Since the tibial plateau involves a major weight bearing joint, the outcome is tied significantly to the resultant alignment and articular congruity after fracture healing with or without surgical intervention. If the joint is stable with good alignment, articular congruity and no loss of joint motion, good results can be expected. If infection, nonunion, cartilage injury or associated soft tissue injuries are not addressed, the functional outcome for the patient will be lower.

It has been reported that higher Schatzker valued fracture produce poorer outcomes due to the extent of trauma along with soft tissue damage is likely.[3]

Measureable outcome measures that can be used are:

  1. Imaging - one year post fracture or further can assess extent of healing[3]
  2. Knee range of movement
  3. Quality of life score - such as the Musculo-skeletal functional assessment[11]
  4. Level of Mobility


There has yet to be a gold standard for accurately predicting the presence of soft tissue injuries in tibial plateau fractures. However, there have been recent studies that have employed preoperative magnetic resonance imaging (MRI) or operative arthroscopy to evaluate the extent of tissue damage.[10]

Medical Management

For tibial plateau fractures, preoperative planning is fundamental. The clinical history, trauma mechanism, age and associated co-morbidities influence the treatment decisions. In the physical examination, the soft-tissues, neuro-vascular function and associated skin lesions should be assessed so that the intervention will be appropriate, depending on the extent of the potential trauma.

Management of these fractures consists of using comprehensive classification systems that are easily reproducible and have valid prognostic value, thereby making it conceptually easier to define tactics and surgical accesses.[3]

The primary aim for orthopaedic management is to restore the congruence of the articular surface and ensure mechanical axis alignment. Any deviations from anatomical condylar position or ligamentous instabilities may lead to an increased likelihood of degenerative osteoarthritis and subsequent reduced functional abilities.[7][2]

Commonly managed by Open Reduction and Internal Fixation (ORIF).[12]


In some more complex cases, fractures can be managed by external fixation followed by further ORIF at a later time. [6][12]

Post tibial plateau fracture osteoarthritis is common (approximately one third of all tibial plateau fractures) due to the articular surface being involved, despite the age of the patient at the time of fracture.[14]

Physical Therapy Management

After a fracture, physical therapy may be required to help ensure return to optimum function as quickly as possible. The patient's goals and psychological state must be considered to reduce the risk of persistent pain following surgery.[15]

Tibial plateau fractures are notoriously difficult to manage, particularly when there is a medial or posteromedial component. The treatment for tibial plateau fractures aims to achieve anatomical reduction of the joint surface and stable osteosynthesis in order to enable early mobilization, so as to prevent complications such as joint stiffness and general post operative complications such as deep vein thrombosis or pulmonary embolism.[2]

Physical therapy protocol varies depending on surgeon preference and there appears to be no set protocol for length of time spent non-weight baring (NWB). The below is a guideline please consult operating surgeon prior to starting physical therapy post-operatively.

NWB stage:

This stage can vary depending on extent of trauma from four weeks to eight weeks. Often immobilised in a cricket pad splint or "Genu-range" style brace locked in full extension.

  • At this stage static quadriceps and passive knee ROM can be started depending on guidance from surgeon. Continuous passive movement machine can be used.[16]
  • Focus on analgesia and swelling reduction.
  • Residual joint ROM exercises i.e. hip and ankle.

Partial Weight Bearing stage:

Gradually increase weight baring on operated leg aiming for fully weight baring by 12 weeks depending on level of pain.

  • Active knee ROM exercises
  • Closed kinetic chain exercises
  • Focus on progression of weight bearing with good movement patterns
  • Basic strengthening program
  • Hydrotherapy (as appropriate)

Fully Weight Bearing stage:

  • Normalising gait pattern
  • Focus of functional activities i.e. sit to stand, stairs
  • Proprioception exercises
  • Return to normal activities of daily living.

High level:

  • Advanced proprioception exercises
  • Sport based drills
  • High level lower limb strengthening exercises

Strengthening exercises should be encouraged in long term management due to the high prevalence of knee osteoarthritis following tibial plateau fracture[14].

Clinical Bottom Line

Tibial plateau fractures do not occur frequently. These fractures are typically caused by high energy trauma, but they can also occur due low energy trauma (e.g. slip and fall).

Physical therapy is very important, but depends on the patient and cause of fracture. Initial presentation will be oedema, pain, loss of ROM, strength and function.

Post-operatively, early ROM and mobility is important. In the sub-acute stages pain, oedema, and ROM must be managed but this will vary depending on surgeon guidance. In the later stages strength, proprioception and restoring normal function are paramount.
