Successful joint replacement

Joint replacement is one of the most successful surgical procedures worldwide. The choice of bone cement is decisive for the long-term success of a cemented endoprosthesis. Register data and studies show that the choice of the right bone cement can contribute to the following aspects:

  • Lower revision rates:
    Up to -25% for the hip and up to -13% for the knee (1)
  • Optimal combination in infection prevention:
    The combination of local and systemic antibiotic prophylaxis achieves the best preventive results in arthroplasty: up to -30% lower revision rates in the knee and up to -50% in the hip (data related to primary procedures) (2-5)
  • Ideal cement intrusion:
    While too little intrusion can lead to an increased risk of aseptic loosening and revisions, a too deep intrusion can be associated with increased rates of heat necrosis and implantation syndrome (6-9)
  • Modern Cementing Technique:
    The combination of different elements is crucial to the long-term surgical outcome: the choice of the bone cement, bone bed cleaning, mixing of bone cement in a vacuum mixing system, retrograde application and application of pressure with a pressuriser
