About

The life expectancy worldwide is increasing and leading to an increase of knee arthroplasty. Also, as millions of people around the world are currently living with a Total Knee Arthroplasty (TKA), the need for revision surgery represents a large public health burden. In this context, FH ORTHO company develops FHK®-CK (prosthesis + ancillary equipment) which is a knee prosthesis for complex first intention and revision knee arthroplasty. This new medical device complements the FHK® standard first-line range (CE marked).

The FHK®-CK ancillary equipment were designed by expert knee surgeons and is simple, reliable and reproducible. It allows for maximum versatility while remaining compact.

By completing the FHK® range of first intention prostheses, the FHK®-CK allows the surgeon to be on the same level as the competitors by having a first intention and semi-constrained prosthesis. This prosthetic arsenal allows the surgeon to opt for the best solution for his patient so that he can regain mobility and a satisfactory quality of life. Also, in case of failure of the FHK® first-line prosthesis, it will provide the surgeon and the patient with a simple alternative to prosthesis replacement. As it has been developed in line with the first intention, inter-compatibility between the two systems is possible, which simplifies the surgical procedure and reduces the risks for the patient.
