Observational Study to Evaluate Clinical Performance and Safety in Total Knee Arthroplasty

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.

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).

Inclusion Criteria:

• Male or female aged 18 - 80 years old at the time of the surgery
• Implanted (or with an indication) with an HLS KneeTec Cementless or hybrid fixation according to the Instructions for Use (IFU)
• Patients agree to consent to collect data from their medical records and agree to answer questionnaires for the purposes of the study.

Exclusion Criteria:

- Patients under guardianship and/or those who, according to the investigator or his delegated research team, will not be able to comply with the study procedures. (e.g. illiteracy, recent psychotic or manic disorders and/or inability to comply with routine follow-up visits.)
