Purpose This study aimed to compare the clinical and radiographic outcomes and arthroscopic findings after high tibial osteotomy (HTO) between neutral and classic targeted coronal alignments in patients with medial meniscus posterior root tears (MMPRTs). Methods Ninety-eight patients with MMPRT were prospectively enrolled in the final cohort and randomized into two groups. Fifty-two patients with the targeted alignment through the Fujisawa point (60–62.5% of the entire tibial plateau width measured from the medial side) during HTO were included in group A, whereas 46 patients with the targeted alignment through the point at 50–55% of the tibial plateau width were included in group B. The clinical and radiographic outcomes and second-look arthroscopic findings were statistically compared for comprehensive assessments. Results After a mean follow-up of 37.1 months, we found no significant differences between the two groups regarding the final Lysholm ( p  = 0.205) and Hospital for Special Surgery scores ( p  = 0.084). However, we only observed significant differences between the two groups in terms of the final hip–knee–ankle angle, weight-bearing line ratio, and medial proximal tibial angle ( p
