About this study
Official title: Observational Study to Evaluate the Performance and the Safety of the HLS KneeTec Cementless or Hybrid Fixations in Total Knee Arthroplasty
The aim of this study is to assess the long-term performance and safety of HLS KneeTec cementless and hybrid fixation knee prosthesis when used in standard medical practice.
Read the detailed description
It is planned to collect prospective and retrospective data from a continuous and exhaustive series of patients in French sites where Total Knee Arthroplasty with HLS Kneetec cementless and hybrid fixation knee prosthesis is performed routinely
All patients treated with HLS KneeTec (cementless or hybrid versions) implant will be included. All eligible patients seen in consultation and who agree to participate in the study should be included, systematically and consecutively, since the initiation of the study.
Patients will be assessed according to the usual practice of the investigator at each participating site before surgery and then at the follow-up (FU) visits as following: 4 months (+/- 2 months); 1 year (+/- 2 months); 5 years (+/- 12 months) and 10 years (+/- 12 months).

Questions about this trial
What is this clinical trial studying?
An observational study of Total Knee Arthroplasty and Knee Disease, run by Corin at 3 sites in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 6 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: the clinical data collected to date are sufficient for regulatory requirements). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluation of implant survival in subjects receiving a total knee arthroplasty with the HLS KneeTec cementless and hybrid fixations up to 10 years after the surgery (time frame: 10-year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2025; AzTrials last refreshed its copy on 31 Oct 2026.
