unicondylar Fixed-Bearing joint replacement


The ACS® Uni FB is an unicondylar fixed-bearing surface replacement, that is characterized by anatomically shaped metal components and high-quality materials. The PE insert is firmly anchored on the tibial component. Femoral pegs and fins ensure high rotational stability.

Product details


The decision for replacement of the joint should be based on careful evaluation. The indication for this type of surgery should only be made when all other conservative or surgical alternatives are less promising.
The risk of post-operative complications can be limited by careful evaluation of the individual anatomical and load conditions, the condition of the soft tissues and the condition of the bone bed for the implants.
The provision of prostheses is generally indicated only in patients whose skeleton is fully grown.
Before intervention, preoperative examinations should be performed. The examinations depend on the patient’s history.
Under consideration of these conditions knee joint replacement with the PB Uni Knee System applies to the following indications:

  • Severe destruction of one compartment of the joint with profound limitations of function where other therapies are likely to be less successful.
  • Postoperative conditions existing because of previous surgery with or without implantation of prosthesis.

Important conditions which have to be fulfilled are:

  • Intact cruciate and collateral ligaments.
  • Intact articular cartilage and intact meniscal cartilage of the opposite compartment.
  • No pre-existing substantial malposition or flexion contracture.

The surgeon decides which version of prosthesis for the individual patient is used. This decision depends on several factors, such as the age and the patient's weight, bone quality, shape of the bone and deformation of the joint.
