Therefore, axial malalignment plays an important role in the development and the progression of osteoarthritis (OA) (1).

The medial opening wedge (MOW) high tibial osteotomy (HTO) was first described by Debeyre and Patte in 1951 (2). Formerly intended as a definitive treatment strategy for medial compartment knee OA, HTO became a widespread procedure in the treatment of unicompartmental OA of the knee. The leading intent of HTO is to transfer the load of the knee joint correcting the mechanical axis of the lower extremity in order to reduce pain, slow down the degenerative OA process and avoid or delay the joint replacement (3,4). Lately, due to the success of total and unicompartmental knee replacement (TKR and UKR), HTO fell...
