These procedures have produced great short\u2010term and mid\u2010term results. As no systematic review has examined their long\u2010term results yet, the goal of this article was to compare the results of all articles about lateral closing and medial opening wedge high tibial osteotomies, published after the year 2000, with a mean follow\u2010up of more than 10 years. A systematic search of the Medline, Web of Science and Cochrane databases resulted in the inclusion of 30 articles. All these studies combined examined the results of 7087 high tibial osteotomies in a total of 6636 patients after a mean follow\u2010up of more than 10 years. Primary outcome measures were the survival rate of the osteotomy, functional scores, patient satisfaction and pain scores. Secondary outcome measures were alignment correction and the identification of factors influencing the survival of the osteotomy. The 5\u2010year, 10\u2010year, 15\u2010year and 20\u2010year survival rates, respectively, ranged from 86 to 100%, 64\u201397.6%, 44\u201393.2% and 46\u201385.1%. The subjective scoring systems showed an improvement postoperatively that was maintained until final follow\u2010up. The anatomical and mechanical tibiofemoral axis were, respectively, corrected to a mean of 7.3\u00b0\u201313.8\u00b0 of valgus and 0.6\u00b0\u20134\u00b0 of valgus. The results of the articles evaluating the influence of potential risk factors were contradictory. Despite the low quality of the available evidence, the lateral closing and medial opening wedge high tibial osteotomy seem to remain valid long\u2010term treatment options for patients with painful varus malalignment caused by isolated medial compartment osteoarthritis of the knee. The available results indicate that the need for arthroplasty could be delayed for more than 15 years in the majority of patients. However, higher\u2010quality studies are needed to confirm these findings. As a systematic review is assigned a level of evidence equivalent to the lowest level of evidence used from the analyzed manuscripts, the level of evidence of this systematic review is
