PROs included the forgotten joint score (FJS), Oxford knee score (OKS) and knee injury and osteoarthritis outcome score (KOOS) subscales: Pain, Symptoms, ADL, Sport and QOL. Stress radiographs were divided into three types, quantifying the amount of medial space opening and deformity correction. Data were collected at preoperative, intraoperative, 4 weeks, 6 months, 1\u2010year, 2\u2010year and 5\u2010year.
