Purpose: The purpose of this study was to retrospectively analyse the clinical, functional and radiological outcomes, and the long-term survivorship of the NexGen Legacy Posterior Stabilised (LPS) knee prosthesis (Zimmer Biomet, Warsaw, IN, USA). Methods: Between 1996 and 2001, 197 primary NexGen LPS total knee arthroplasties (TKAs) were implanted by a single surgeon; 132 prostheses in 124 patients with a minimum follow-up of 15 years were included in the study. Surgical procedure and post-operative care were the same for all patients. All patients were assessed through the International Knee Society (IKS) scores and range of motion (ROM). A complete radiological study was performed for all patients. Failure was defined as revision of at least one prosthetic component for any cause. Results: IKS knee and function scores, as well as ROM and leg alignment, significantly improved at the latest follow-up (p ≤ 0.05). No significant differences were found between fixed- and mobile-bearing groups. Seven implant failures were reported; the implant survival rate (overall) was 94.7% at the latest follow-up. Conclusions: This study showed optimal survivorship of the NexGen LPS, associated with a significant improvement in overall outcomes at a minimum follow-up of 15 years. © 2017 SICOT aisbl

Patellar instability is one of the most common conditions treated in the field of orthopedics. A diagnosis based on clinical and instrumental tests allows proper treatment planning. The techniques at the disposal of the surgeon – arthroscopic, arthroscopically-assisted and open – are numerous, and extensor mechanism realignment procedures are among the ones most frequently used. The choice of the most appropriate technique must be made case by case, considering the peculiarities of the individual patient. © 2013, CIC Edizioni Internazionali s.r.l. All rights reserved.
