The present study provides survival rate and functional outcome preoperatively and after 6, 12, 24, 36 and 60\u00a0months following open\u2010wedge high tibial osteotomy. Hypothesis of the authors was high survival rates after 5 years with still remaining satisfying functional results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Sixty\u2010two patients suffering from tibial conditioned knee joint varus deformity and medial compartment OA that underwent high tibial osteotomy using an internal plate fixator (TomoFix\u2122, Synthes) were included. Functional outcome was evaluated prior to surgery and in the further clinical course using standard instruments (IKDC score, Lysholm score). Treatment failure was defined as the need for total knee arthroplasty (TKA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fifty\u2010one patients (mean age 46.8 \u00b1 10.2 years) were available at a mean of 60.5 (SD \u00b1 2.5) months (follow\u2010up rate 82.3 %) postoperatively. Sixty\u2010month IKDC (69.4 % SD \u00b1 18.6) and Lysholm (76.6 SD \u00b1 20.5) improved significantly when comparing with preoperative values (IKDC 44.6 SD \u00b1 17.8; Lysholm 52.1 SD \u00b1 20.8). Two of 51 subjects underwent TKA, resulting in a survival rate of 96 % among those patients followed (51 of 60; 85 %). Overall complication rate was 8.6 %.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>With a survival rate of over 96 % at 5 years, high tibial osteotomy seems to be a reliable treatment option with satisfying clinical outcome. Functional outcome was stable following 60\u00a0months. While a delay of the necessity for TKA seems likely with regard to the survival rate demonstrated in this article, possible avoidance needs to be demonstrated by longer follow\u2010up
