PMCF Study on the Safety, Performance and Clinical Benefits Data of the NexGen TM Augmentation Patella

Rheumatoid Arthritis Clinical Trial

Official title: Post-market Clinical Follow-up Study to Confirm Safety, Performance and Clinical Benefits Data of the NexGen® Trabecular Metal™ (TM) Augmentation Patella (Implants and Instrumentation)- A Retrospective and Prospective Consecutive Series Study

Status Withdrawn

Clinical Trial Summary

The study is a single-center, retrospective and prospective, non-randomized, non-controlled and consecutive series post-market study. The purpose of this study is to confirm safety, performance and clinical benefits of the NexGen TM Augmentation Patella. The primary objective is the assessment of safety by analyzing implant survivorship. This will be established by recording the incidence and frequency of revisions, complications and adverse events. Relation of the events to implant, instrumentation and/or procedure should be specified. The secondary objective is the assessment of performance and clinical benefits by recording patient-reported clinical outcome measures (PROMs) as well as radiographic outcomes.

Clinical Trial Description

The Nexgen TM Augmentation Patella is intended to help compensate for significant bone loss in the patella during revision total knee arthroplasty. One site will be involved in this study. The aim is to include a total of 25 consecutive series patients who received the NexGen TM Augmentation Patella starting from 2014 at the Inselspital Bern. All potential study subjects will be required to participate in the Informed Consent Process. Baseline data from the preop, intraop and immediate post-op intervals will be available in medical notes and collected retrospectively. During follow-up visits at 1, 3, 5, 7 and 10 years post-op (depending on patients' date of surgery), the patient will be asked to complete patient questionnaires. Moreover, a clinical assessment and a radiographic evaluation will be conducted. In addition, any complications and adverse events will also be collected during these follow-up visits. ;
