Simultaneous High Tibial Osteotomy and Anterior Cruciate Ligament Reconstruction in knees with Bony Frontal and/or Sagittal Deformities: Review of the Current Literature.

Simultaneous anterior cruciate ligament (ACL) reconstruction (ACLR) and valgus high tibial osteotomy (HTO) alleviates pain in 70% of individuals with ACL deficiency and varus femorotibial osteoarthritis, allows for sustainable stabilization of the knee at the 10-year follow-up and a return to sport (RTS) in 33%-80% of cases, but femorotibial osteoarthritis progression occurs in 39% of cases. The complication rate ranges from 0% to 23.5% (6.5% revision valgus HTO, 17.5% ACL graft failure, 7.7% venous thrombosis). Simultaneous ACLR and HTO leads to satisfactory results in patients with ACL deficiency and varus femorotibial osteoarthritis associated with a high posterior tibial slope (PTS) and appears to have a protective effect on further ruptures in the reconstructed ACL. The younger the patient and the more sporting demands he/she poses, the more we should be inclined to perform a combined intervention (ACLR and valgus HTO).
