Core Tip

Core tip: The ArcosTM Modular Femoral Revision System is a new comprehensive, press-fit revision design. We have evaluated the early results after femoral revision in a consecutive series of 116 patients in a period of three years. This is a fairly large cohort when dealing with arthroplasty reoperations and the special feature of our cohort is that we use a combination of implant-modules which strives for proximal load bearing and fixation, mimicking the concept of the primary hip replacements.
