(#)Contributed equally PURPOSE: To compare clinical outcomes of high tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) for anterior medial osteoarthritis (AMOA) as well as offer surgical recommendations through age stratification. METHODS: Between May 2019 and May 2021, 68 cross-indicated AMOA patients were analyzed. The patients were divided into HTO and UKA groups and further into two age groups of 55-60 and 60-65 years.

Knee joint HSS significantly improved, and VAS score decreased in both groups (P
