BonOs® R / BonOs® R Genta

Bone cement

Hip and knee arthroplasty are successful operations in orthopaedic surgery. Joint replacement leads to pain reduction, an increased range of motion and joint alignment. As a result patients‘ mobility and quality of life are significantly improved. The longevity of implants is influenced by several factors but every success is based on the long-term interface fixation between bone and implant ^[1]. 

In knee arthroplasty cemented fixation is generally preferred and also cemented hip replacement leads to excellent long term results if indications and crucial rules of cementing techniques are followed ^{[2, 3]}. Cemented arthroplasty leads to primary stability of the implant and allows immediate postoperative mobilization with full weight bearing. The load and shear forces applied are transmitted through the bone cement into bone. Aseptic component loosening implies that the interface has failed to some degree. Studies have shown that the strength of the bone cement interface is dependent on cement penetration and interdigitation with the host bone ^{[4, 5]}. 

A high quality bone cement as well as a correct application ensures reproducible clinical outcomes and reduces the risk of implant failures ^[6]. This brochure describes BonOs® R and BonOs® R Genta bone cement, application accessories for hip and knee arthroplasty and a comprehensive description of cement application.
