  1. K/L grade Kellgren-Lawrence grade, OWHTO open-wedge high tibial osteotomy, OWDTO open-wedge distal tibial tuberosity osteotomy, SD standard deviation
  2. The knee extension angle is expressed as 0° for full extension, with a negative value for hyperextension and as a positive value for limitation of extension
  3. Data were analyzed using the Kruskal-Wallis test, chi-squared test, and one-way analysis of variance
