[Arthroscopically guided osteosynthesis of lateral tibial plateau fractures].

Abstract

A prospective study was performed on 16 patients with lateral tibial plateau fractures. All injuries were associated with alpine or cross country skiing. Included in the study were those patients with a 2 mm or greater articular surface depression with radiographic findings consistent with the AO/ASIF classification of tibial plateau fractures, 41 B2.2./B3.1. A combined procedure was performed with arthroscopic visualization of the knee joint and utilization of a cannulated plateau elevator. All fractures were reduced with this device with subsequent autogenous bonegraft and when indicated, transverse cancellous lag screw fixation. Followup was from 1 to 6.5 years for the 15 patients with all but two reporting resumption of activity to pre-injury levels.
