Abstract
PURPOSE OF REVIEW: The purposes of this review are to (1) describe the anatomic and biomechanical rationale for high tibial osteotomy (HTO) in the setting of posterior cruciate ligament (PCL) deficiency, (2) review the indications for concomitant HTO and PCL reconstruction, (3) provide guidance for the clinical assessment of the patient with suspected PCL deficiency, and (4) summarize the key surgical steps necessary to attain the appropriate sagittal and coronal plane corrections. RECENT FINDINGS: The preponderance of available biomechanical data pertaining to the PCL-deficient knee suggests that an increased proximal tibial slope limits posterior tibial translation under axial compressive loads. Moreover, recent clinical data has demonstrated that decreased proximal tibial slope may exacerbate residual anterior-posterior laxity and jeopardize the durability of PCL reconstruction. Thus, in the setting of PCL deficiency, an HTO that increases the posterior tibial slope may be advisable. HTO may be an important treatment adjunct in the surgical management of PCL deficiency. In the setting of chronic injuries and varus malalignment, HTO should be considered in order to ensure a durable ligamentous reconstruction and forestall the progression of secondary osteoarthritis.
