To analyse the frequency of soft tissue injuries associated with tibial plateau fracture through arthoscopy and demonstrate the pattern and treatment of lateral meniscal tear which is the most frequently concomitant injury.

We evaluated the charts, X-rays and arthoscopic records of the 27 patients who had been diagnosed as tibial plateau fracture and received the arthoscopic examination or arthoscopic assisted operative management and analysed the injury pattern, association of schatzker classification and treatment of the 9 patients who had been concomitant with lateral meniscal tear.

In our cases, lateral meniscus tear was the most common among the soft tissue injury it was revealed that a longitudinal tear at the peripheral area was shown in 8 cases, which were treated with meniscal repair and a radial tear of the central area in l cases, treated with partial menisectomy.

Lateral meniscus injury is one of the most frequently concomitant with tibial plateau fracture, In those cases, arthroscopic meniscal repair would be helpful for better prognosis.
