[Intracondylar segment osteotomy: correction of intra-articular malalignment after fracture of the tibial plateau].

Intracondylar deformities after tibial plateau fractures are intra-articular deformities which present within the medial and/or lateral knee compartments. They exist either isolated or in combination with other extra-articular deformities and/or ligament problems. These deformities are complex problems and difficult to treat. While many treatment concepts exist for extra-articular deformities there is limited information available for intra-articular or even intracondylar deformities. Selecting the appropriate procedure for the approach, osteotomy, management of bone defects and cartilage damage is crucial. The authors describe the analysis, planning, treatment and clinical outcome for these rare but difficult problems and present step by step details of the surgical technique.
