Advancing Revision Arthroplasty: Oscar Pro Firmware and Instrumentation Upgrades
The Challenge of PMMA Bone Cement Removal in Revision Arthroplasty
Revision arthroplasty presents a set of technical challenges, particularly when it involves the removal of PMMA bone cement. Limited visualization, difficulty in distinguishing cement from bone, and unpredictable procedure times may lead to complications. In severe cases, this can compromise bone stock and require additional reconstructive materials or costly prostheses.
How Oscar Pro Technology Supports Orthopedic Surgery
Oscar™ was developed to address these challenges. By using ultrasound energy, the system softens the cement shell that holds the implant in place, allowing surgeons to sequentially deploy specialized probes to collect and remove cement from the host bone. This technique reduces manual force and is designed to lower the risk of bone fracture or perforation. Over the years, Oscar has become one of the most widely adopted technologies in joint revision surgeries where cement fixation is involved.
With the 4th generation Oscar Pro™, the platform has evolved into an open system supporting not only cement removal and uncemented prosthesis revisions, but also specific osteotomies using ultrasound. This expansion enables healthcare professionals to apply Oscar Pro across multiple surgeries, offering a versatile solution for complex limb reconstruction procedures.
