AB  - PURPOSE: To compare the changes in patellofemoral (PF) joint alignment, focusing 
      on multiple planes, between two different types of biplanar medial opening-wedge 
      high tibial osteotomy (OWHTO). METHODS: Patients who underwent biplanar OWHTO 
      between July 2017 and May 2021 were retrospectively evaluated. They were 
      allocated to either the supra-tubercular (ST)- or retro-tubercular (RT)-OWHTO 
      group. The following radiologic parameters were compared between the two groups: 
      1) weight-bearing line ratio (WBLR), 2) patellar height, 3) posterior tibial 
      slope (PTS), 4) tibial tubercle-trochlear groove (TT-TG) distance, 5) TT-TG 
      angle, and 6) femoral shaft-patellar tendon (FS-PT) angle. Clinical outcomes and 
      the minimal clinically important difference (MCID) were also evaluated. RESULTS: 
      In total, 104 knees that underwent ST-OWHTO and 105 knees that underwent RT-OWHTO 
      were evaluated. The patellar height significantly decreased only after ST-OWHTO 
      (P < .001). The TT-TG distance and FS-PT angle significantly increased, more 
      after ST-OWHTO than RT-OWHTO (mean change value: 5.72 mm vs 1.91 mm; P < .001 for 
      TT-TG distance; and 4.72 degrees  vs 1.80 degrees ; P < .001 for FS-PT angle). The TT-TG angle 
      increased significantly after ST-OWHTO (mean change value: 7.62 degrees ; P < .001) but 
      decreased after RT-OWHTO mean change value: -4.30 degrees ; P < .001). The PTS more 
      increased after RT-OWHTO than after ST-OWHTO (mean change value: 0.91 degrees  vs 1.69 degrees ; 
      P = .003). Clinical outcomes in both groups improved postoperatively, and no 
      significant differences were observed between the groups. CONCLUSIONS: RT-OWHTO 
      resulted in lesser changes in multiplane PF joint alignment than ST-OWHTO. 
      However, no difference was observed in clinical outcomes between both groups, and 
      PTS increased after RT-OWHTO. Therefore, these aspects of RT-OWHTO should also be 
      considered. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
