Ten patients with type B fractures of the tibial plateau (according to the
AO-classification) were treated by arthroscopically-assisted reduction, aut
ologous bone grafting due to osseous defects and transcutaneous screw fixat
ion. Concomitant intra-articular lesions were treated arthroscopically at t
he same time. We did not see any complications intra- or post-operatively a
nd no secondary displacement of the fracture fragments. All patients gained
full free motion in the operated knee. Considering the minimal soft tissue
trauma, the diagnostic value, therapeutic options and good results, we reg
ard arthroscopic minimally-invasive osteosynthesis as ideally suited for ce
rtain type B fractures of the tibial plateau.
