The decision to resurface the patella during total knee arthroplasty remains controversial. Aim of our study was to evaluate the functional difference between patients undergoing medial rotation knee (MRK) replacement with and without patellar resurfacing at our hospital. We did a retrospective analysis of patients undergoing MRK total knee replacement (Matortho) at our hospital between 2008 and 2017 performed by 2 surgeons. Patients were recalled for a clinical review from Oct 2017 for recording of Oxford knee, Baldini and Ferrel scores. Mann-Whitney U test was used for non-parametric data (SPSS v24).Background
