Abstract
BackgroundAnterior cruciate ligament (ACL) injury may be associated with genu varum. There are a few indications in which the varus deformity can be corrected at the time of ACL reconstruction. However, as the genu varum originates mostly from the tibia and the simultaneous presence of ACL deficiency and femur originated genu varum is uncommon, only a few papers have described their management for ACL deficient patients with femur originated genu varum.Case presentationA young patient visited our clinic with a complaint of right knee pain and giving way. Further work up revealed a full mid substance ACL tear, mild medial knee osteoarthritis and femur originated genu varum of his right knee. He was managed with simultaneous ACL reconstruction and distal femoral valgus osteotomy.ConclusionsAny corrective osteotomy for genu varum should be performed at center of rotation angle. Isolated ACL reconstruction in patients with simultaneous ACL deficiency and genu varum may hasten the knee degeneration.Level of evidenceIV

Knee valgus osteotomy combined with Anterior Cruciate Ligament reconstruction (ACL-R) should be considered in active young patients with genu varum and symptomatic ipsilateral Anterior Cruciate Ligament (ACL) deficiency if the affected knee has either medial compartment Osteoarthritis (OA) or lateral thrust [1]
Summary
Anterior cruciate ligament (ACL) injury may be associated with genu varum. There are a few indications in which the varus deformity can be corrected at the time of ACL reconstruction. Isolated ACL reconstruction in patients with simultaneous ACL deficiency and genu varum may hasten the knee degeneration. Background Knee valgus osteotomy combined with Anterior Cruciate Ligament reconstruction (ACL-R) should be considered in active young patients with genu varum (varus angle > 5 degrees) and symptomatic ipsilateral Anterior Cruciate Ligament (ACL) deficiency if the affected knee has either medial compartment Osteoarthritis (OA) or lateral thrust (double varus) [1].
