AB  - To evaluate retrospectively any association between the degree of deformity 
      correction by medial open-wedge high tibial osteotomy (HTO) and patellofemoral 
      joint degeneration. We hypothesized that development of patellofemoral joint 
      degeneration depended on the degree of intraoperative deformity 
      correction.Fifty-seven patients who underwent medial open-wedge HTO for treatment 
      of osteoarthritis in one knee were included in this study. Knees were classified 
      into degeneration (D) and non-degeneration (ND) groups according to worsening of 
      the patellar and/or femoral trochlear cartilage at the time of hardware removal 
      (D group, 27 knees) and no degeneration or improvement (ND group, 30 knees). We 
      compared pre- to post-surgery change in hip-knee-ankle angle (HKA) and 
      medial-proximal-tibial angle (MPTA), open-wedge HTO correction angle, and 
      arthroscopic findings between groups.Mean age, height, weight, and body mass 
      index were 54.1 +/- 9.9 years, 160.4 +/- 8.7 cm, 66.4 +/- 12.1 kg, and 25.7 +/- 3.3 kg/m, 
      respectively. Change in both HKA and MPTA differed significantly between groups. 
      The MPTA cut-off values to predict patellofemoral degeneration were determined to 
      be 10 degrees , associated with an AUC of 0.75 (95% confidence interval [CI] 
      0.62-0.87).This study evaluated retrospectively the effect of the correction 
      angle during medial open-wedge HTO on patellofemoral joint degeneration. If 
      deformity correction exceeds an MPTA of 10 degrees  during open-wedge HTO, degeneration 
      of patellofemoral joint needs to be considered.Level of evidence: Level IV.
