Approximately 10 years ago a total knee arthroplasty system with a modern universal femoral component was introduced. It includes a symmetrical femoral and tibial component. The purpose of this study was to evaluate the 6-year clinical outcomes of this implant from a single surgeon. A retrospective chart review was performed on all patients who received a TJO Klassic® Knee from January 2014 to January 2015 (Total Joint Orthopedics Inc., Salt Lake City, Utah). In total there were 131 patients (149 knees) who underwent total knee arthroplasty with this system. A retrospective chart review was performed including demographics, preoperative and postoperative clinical assessments including Knee Society score (KSS), range of motion, and radiographic assessment. There were 60 males (45.8 %) and 71 females (54.2 %) with 149 knees available for review. Mean age at time of surgery was 67.4 years (45–91) and BMI was 32.6 kg/m2 (16.6–54.6). The patella was left unresurfaced in 37 knees (24.8 %), KSS scores including the clinical and functional components all improved significantly (p
