What this trial studies

This clinical trial evaluates the performance and safety of the FHK®-CK knee prosthesis designed for complex primary and revision total knee arthroplasty. The prosthesis, developed by FH ORTHO, aims to address the needs of patients requiring knee replacement due to significant bone defects or previous surgical failures. The study will involve patients who meet specific criteria and will assess functional performance and safety outcomes through standardized questionnaires and clinical evaluations. The FHK®-CK system is designed to provide surgeons with a versatile and reliable option for knee arthroplasty.

Who should consider this trial

Good fit: Ideal candidates include patients requiring knee arthroplasty for primary or secondary gonarthrosis, especially those with major bone defects or previous failed surgeries.

Not a fit: Patients with ongoing acute infections, mental or neuromuscular disorders, or known allergies to the prosthesis components may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes for patients undergoing knee replacement surgeries, particularly those with complex needs.

How similar studies have performed: Other studies have shown success with similar prosthetic approaches, indicating potential for positive outcomes with this new device.

Eligibility criteria

Inclusion Criteria:

* Patient requiring knee arthroplasty for primary or secondary gonarthrosis:

  \* For primary intention arthroplasty: Patient with either
  * major axial deviation,
  * major peripheral failure or
  * bone defect;

    \* For prosthesis revision surgery: Patient who have had a failed 1st implantation, with or without bone defects.

* Patient requiring knee reconstruction;
* Patient with any medically significant findings or significant history that may impact the safety, interpretation of results, and/ or participation of the subject in the clinical trial, as determined by the investigator;
* Patient with an existing knee or hip prosthesis (outside knee to be operated) that may impact the evaluation of the FHK®-CK prosthesis;
* Patient concurrently participating in another clinical trial or who has recently participated in another clinical trial for which the exclusion period has not been completed.
