Double-Level-Osteotomie zur Korrektur iatrogener Fehlstellung nach juvenilem VKB-Bracing
摘要
Corrective osteotomies are established treatment procedures for the correction of coronal and sagittal limb axis deformities. In this case of a 32-year-old woman, both femoral and tibial malalignment were observed following previous anterior cruciate ligament surgery (transtibial and transfemoral bracing) at the age of 11. The surgery caused injury to the medial epiphysis of the proximal tibia, leading to premature closure of the growth plate and a resulting varus deformity. Femoral fixation injured the lateral epiphysis of the distal femur, resulting in a valgus deformity. Correction was achieved via a varus-producing osteotomy of the femur (medial closing wedge distal femoral osteotomy [MCWDFO]) and a valgus-producing osteotomy of the tibia (medial opening wedge high tibial osteotomy [MOWHTO]). In this case of a focal cartilage defect, membrane-assisted bone marrow stimulation of the lateral femoral condyle was performed. During further follow-up, the patient remained symptom-free.
