There is a lack of studies comparing patient\u2010reported outcomes (PROs) of both implants. This study aimed to document and compare PROs of MB UKA to FB UKA at 6, 12 and 24\u00a0months after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A single high\u2010volume surgeon, retrospective cohort study with prospectively collected data of two groups of UKA patients, with a MB (<jats:italic>n<\/jats:italic>\u2009=\u200966) or FB (<jats:italic>n<\/jats:italic>\u2009=\u200997) implant. Primary outcome was patient satisfaction (0\u201310; NRS). Secondary outcomes were pain at rest (NRS), pain during activity (NRS), function (OKS, KOOS\u2010PS), quality of life (EQ\u20105D\u20103L), anchor pain, anchor function and anchor recovery. PROs were collected 6, 12 and 24\u00a0months postoperatively.
