Hip\u2010knee\u2010ankle angles and PROs, including Lysholm and visual analog scale, showed significant improvements postoperatively for both MOW and LCW HTO for all included studies. For the studies that reported on it, posterior tibial slope (PTS) was significantly increased in 4 of the 9 MOW studies and significantly decreased in 8 of the 9 LCW studies. Patellar height was significantly decreased in 4 of the 5 MOW studies, while none of the 4 LCW studies reported any changes. Three comparison studies reported a higher conversion to total knee arthroplasty in the LCW cohort; otherwise, survivorship at 10 years was comparable between studies. The MOW cohort had higher rates of tibial fractures, while the LCW cohort had higher rates of nerve injuries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This systematic review found comparable hip\u2010knee\u2010ankle angle correction and PROs between patients undergoing MOW or LCW HTOs to treat medial compartment osteoarthritis. Survivorship at 10 years was comparable between MOW and LCW HTOs; however, some MOW and LCW HTO comparison studies reported higher conversion to total knee arthroplasty for LCW HTO. Medial opening wedge HTO typically results in an increased PTS, decreased patellar height, and tibial fractures, while LCW HTO typically results in decreased PTS, no change in patellar height, and common peroneal nerve injuries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n
