Patient\u2010reported outcome measures (PROMs) were collected from 60 patients (27 bi\u2010UKA and 33 TKA patients) 2 years following surgery, including Oxford Knee Score (OKS), New Knee Society Score (NKSS), Forgotten Joint Score, EQ\u20105D\u20103L, UCLA activity scale, Hospital Anxiety and Depression Scale, Pain and Stiffness Visual Analogue Scales, Satisfaction and Range of Motion. Complications were also recorded at each visit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>TKA and bi\u2010UKA continue to offer comparable PROMs. The clinical NKSS demonstrated a significant difference between the two interventions, TKA 59.5 (37\u201365) versus bi\u2010UKA 26.0 (22\u201340) (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
