The aim of this study was to compare OR resource use and clinical Outcome after Total Knee Arthroplasty (TKA) using Patient-specific (PSI) or conventional Instrumentation.~For this purpose, economic variables of the surgery (number of instrument trays, setup and cut-sew-time), radiological alignment and patient reported outcomes (VAS Pain Scale, Oxford Knee Score, EQ-5D) were assessed. Cost per QALY (quality-adjusted life year) was assessed using the German DRG reimbursement and the EQ-5D.~A total of 139 TKA with PSI or conventional instrumentation were included in three Centers and were assessed before surgery, as well as 6 weeks, 6 and 12 months postoperatively.
