Prospective, Randomized Study Between Insall-Burstein II and NexGen Legacy with a Minimum 9-Year Follow-Up JOURNAL OF ARTHROPLASTY Oh, K., Goodman, S. B., Yang, J. 2011; 26 (8): 1232-1238

Abstract

A randomized, prospective, comparative study was performed in 2 related, adjacent generation posterior stabilized total knee prostheses, to evaluate whether the newer design improved the clinical and radiographic outcome for treatment of advanced osteoarthritis of the knee. Ninety one total knee arthroplasties in 84 patients (45 Insall-Burstein II and 46 NexGen Legacy posterior stabilized [both from Zimmer, Warsaw, Ind] prostheses) with an average of 10.3 years of follow-up (range, 9-11.8 years) were included. The preoperative diagnoses were primary osteoarthritis in all patients. At the latest evaluation, there were no significant differences detected in the mean clinical and functional knee scores, average postoperative active range of motion, and anterior knee pain between the Insall-Burstein II and the NexGen Legacy groups postoperatively.
