FHK – Fixed-bearing total knee arthroplasty
The fixed-bearing FHK implant can be used with or without an intact posterior cruciate ligament. The surgeon can select between a PCL-sparing fixed bearing implant or a posterior-stabilised implant by adding a posterior cam. Implants available in cemented and cementless versions.
The patellar implant is available in two versions:
– resurfacing (onlay)
Depending on the patient’s bone quality, tibial extension stems are available in two lengths and two diameters.
The FHK instrumentation consists of 4 baskets that allow the surgeon maximum flexibility intra-operatively when selecting the:
– order of bone cuts
– femoral reference
– femoral cuts
– tibial aiming method
Features and materials
– The tibial and femoral components are made of CoCr (cobalt-chrome)
– The inserts are made of UHMWPE
– The inner surface of cementless implants are coated with plasma-sprayed pure T40 titanium and a hydroxyapatite layer for secondary fixation
