The alignment in TKA has been identified as being of importance to prevent early implant failure and patient dissatisfaction. Our hypothesis was that patients with a preoperative varus deformation remaining in a slight varus alignment as their natural alignment after TKA will have superior clinical results compared with patients who are restored in neutral alignment. A total of 115 patients were corrected from varus to neutral (varus\u2013neutral) and in 33 patients a preoperative varus alignment was kept in varus (varus). Standardized preoperative and postoperative full-length hip\u2013knee\u2013ankle radiographs under full weight-bearing conditions were performed in all patients. The patients' knees were categorized preoperatively and postoperatively based on the angle between mechanical femoral axis and mechanical tibial axis. Knees with alignment between\u2009\u00b1\u20093 degrees were categorized as neutrally aligned, whereas alignment within\u2009\u2264\u2009\u20133 degrees was categorized as varus. The Knee Injury Osteoarthritis Outcome Score (KOOS) and Oxford Knee Score were determined retrospectively. The varus group scored significantly better in total KOOS (p\u2009&lt;\u20090.05) compared with the varus\u2013neutral group. Also, a trend was visible in the Oxford Knee Score but this was not significant (p\u2009&gt;\u20090.05). This trend was even more evident in varus knees which were slightly undercorrected. The results support the assumption that leaving a residual varus alignment after TKA leads to better functional outcomes in TKA for patients with preoperative varus osteoarthritis.<\/jats:p>","DOI":"10.1055\/s-0038-1669788","type":"journal-article","created":{"date-parts":[[2018,9,7]],"date-time":"2018-09-07T18:48:11Z","timestamp":1536346091000},"page":"820-824","source":"Crossref","is-referenced-by-count":25,"title":["Neutral or Natural?
