General considerations

These are rare injuries and can often be treated nonoperatively if the extensor mechanism is intact.

These fractures are classified by UCPF as V.4-A.

Nondisplaced tibial plateau or tubercle

Etiology

Avulsion fractures e.g. avulsion of the tibial tubercle.

Clinical signs

Imaging

Plain X-rays remain the first line of investigation.

CT scan can be used to assess the size and position of fragments, implant stability, and bone stock.

Comparison with previous X-rays is useful.
