- Titel:
- Biomechanical Rationale of Correction Osteotomy and Overcorrection
- Abstract:
- Lower extremity alignment is a factor paramount in the etiology across various degenerative as well as ligamentous pathologies of the knee and has been shown to be predictive for the postoperative success in a range of reconstructive procedures. Alignment corrective osteotomies have demonstrated to produce favorable outcomes by unloading the affected compartment and optimizing the biomechanical conditions for ligamentous stability, with a consensus on the optimal osteotomy type and configuration as well as targets of correction lacking to date. With valgus correction aiming for a neutral alignment, in varus correction, biomechanical as well as clinical evidence advocates an overcorrection to a valgus of 50%-65% on the tibial plateau depending on the underlying pathology. Solid evidence advocates to factor a preoperative intraarticular deformity, patellar height as well as collateral ligamentous laxity into planning and proposes a choice of tibial or/and femoral correction aligned with a slope-neutral preservation of a physiological corona! knee joint line of <4 degrees. In the setting of a recurrent anterior cruciate ligament deficiency with a pathological posterior slope >12 degrees, the biomechanical data support a correction via anterior closing wedge osteotomy and propose a simultaneous correction of concomitant varus malalignment depending on the state and competence of medial and (postero-)lateral structures.
