(K013385) . - Aesculap Implant Systems Columbus REVISION Knee System (K083772) . # DEVICE DESCRIPTION The EnduRo Knee System is a cemented prosthesis with a rotating hinge design. The femoral component, tibial plateau and extension stems are manufactured from CoCrMo. The tibial "gliding surfaces" and patella are manufactured from UHMWPE. The tibial mask is made from PEEK Optima® (LT1). The axial sleeve and femoral bushing components are produced from PEEK Optima® (LT1CA30). The system is made up of numerous components available in various sizes. The femoral, tibial plateau, and extension stems are also available with a ZrN (zirconium nitrate) coating. All components are sterile and for single use only. # PURPOSE FOR PREMARKET NOTIFICATION The purpose for this submission is to gain marketing clearance for the Aesculap Implant Systems EnduRo Knee System. {1}------------------------------------------------ K10 1815 Page 2 of 2 ### INDICATIONS FOR USE The EnduRo Knee System is indicated for use in reconstruction of the diseased knee joint caused by osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, the need to revise failed arthroplasties or osteotomies where pain, deformity or dysfunction persist, and for patients suffering from correctable valgus or varus deformity and moderate flexion contracture. Hinge knee systems are designed for use in patients in primary or revision surgery, where the posterior cruciate ligament and one or both of the collateral ligaments are absent or insufficient. The femoral and tibial augments are to be attached to their respective components with a fixation screw or screws. The EnduRo Knee System is intended for cemented use only. # TECHNOLIGICAL CHARACTERISTICS(compared to Predicate(s)) The components of the Aesculap Implant Systems EnduRo Knee System are offered in a similar range of shapes and sizes as the predicate devices. The material used for the Aesculap Implant Systems device is the same as that used to manufacture the predicate devices. # PERFORMANCE DATA The following tests were performed to support substantial equivalence: - Range of Motion of the EnduRo Knee System . - Wear testing of the EnduRo Knee System . - Femoral Endurance Properties of the EnduRo Knee System . - Endurance Properties of the Modular Femoral Stem Assembly of the EnduRo Knee . System - Tibial Tray Endurance Properties of the EnduRo Knee System . - Endurance Properties of the rotating axis component in A/P direction of the EnduRo Knee . System - Endurance Properties of the Modular Tibial Stem Assembly of the EnduRo Knee System . - . Varus-Valgus Endurance Properties of the EnduRo Knee System - TibioFemoral Contact Area/Stress at Different Angles of Flexion for the EnduRo Knee . System - PatelloFemoral Lateral Subluxation Resistance of the EnduRo Knee System . - PatelloFemoral Contact Area/Stress at Different Angles of Flexion for the EnduRo Knee . {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services. The logo consists of a stylized caduceus symbol, which is a staff with two snakes coiled around it, and the words "DEPARTMENT OF HEALTH & HUMAN SERVICES USA" arranged in a circular pattern around the symbol. The caduceus is black, and the text is also black.
