FH ORTHO SAS Knee Observatory

Knee Surgery Clinical Trial

Official title: Post Market Clinical Follow-up of Knee Surgery Using FH ORTHO SAS Medical Devices (FH ORTHO SAS Knee Observatory)

Status Not yet recruiting

Clinical Trial Summary

The objective of this observatory is to generate additional real life clinical data in accordance with local regulation (i.e. Post-Market Clinical Follow-up (PMCF) study, a study carried out following the European Conformity (CE) marking of a device and intended to answer specific questions relating to clinical safety or performance (i.e. residual risks) of a device when used in accordance with its approved instructions for use (IFU). The difficulty of such an observatory is to be able to collect data on the different versions of the devices, on the different possible combinations of implants of an knee arthroplasty. The observatory must also be able to cover devices used in ligament reconstruction surgery. The observatory will be based on the principle of a "dynamic" cohort during the inclusion period, i.e. with possible inclusions to replace the premature exits. Technical solutions will be implemented to facilitate data collection from surgeons (electronic Case Report Form (eCRF) and from patients (Electronic Patient Reported Outcome (ePRO) on smartphone/tablet/computer) when feasible. The data to be collected and the different follow-up times are based on our state-of-the-art, clinical evaluation plans and clinical evaluation reports.

Clinical Trial Description

PMCF as part of CE mark renewal, to answer questions related to the safety and clinical performance of the devices, when used according to their approved instructions for use. This is an European, prospective and retrospective, multicenter, non-comparative study. Randomization is considered impossible due to surgeon preference, anatomical conditions and other patient factors, and the use of different techniques. This observatory is non-comparative, due to the absence of a gold standard and the technical, logistical and contractual constraints involved. This PMCF study (CE-marked MD, any class, used as intended) provide additional non-burdensome and non-invasive procedures. The Observatory will therefore be based on the principle of a "dynamic" cohort, i.e. with possible exits and inclusions throughout the Observatory period. The aim of this methodology is to have a sufficient number of patients to be able to carry out descriptive statistical analyses each year, and to be able to calculate the evaluation criteria with the longest possible follow-up of results. Data will be collected before surgery, during surgery and at follow-up visits. Data collection will focus on obtaining short- and long-term data for performance and safety evaluation (up to 20 years for knee arthroplasty prostheses; up to 5 years for knee ligament reconstruction devices). In the case of knee arthroplasty, it is recommended to have performance and safety data at 1, 2, 5 and 10 years of follow-up, as well as safety data at 15 and 20 years if possible. In the case of ligament reconstruction, it is recommended to have performance and safety data at 1 and 2 years, as well as safety data at 5 years. The platform will be able to send automatic notifications to surgeons to remind them of scheduled patient follow-ups, missing data, and encourage them to include new patients if necessary. Self-questionnaires will be completed by patients via a web-based platform, available on computer or smartphone/tablet. Alternatively, patients will complete paper self-questionnaires, which will then be entered into the database by the investigating team. It will also be possible to arrange for direct telephone contact with patients by an independent structure guaranteeing non-dissemination of nominative data (e.g. CRO). Telephone contact can also be made if the patient is geographically remote or has difficulty travelling. Patient recruitment: Continuous, consecutive, prospective and retrospective (for some implants because few implants have been used for this condition) recruitment to guarantee a minimum number of patients per type of device. Individual written information for each patient will be mandatory. A signed patient consent form will be required in Europe, after sufficient time for reflection. ;
