Three-compartment knee prosthesis BPK-S

revisionmobile-bearing

The addition of new implant components has expanded the BPK-S Integration knee system into a comprehensive full system that provides solutions for nearly every initial setting in total knee arthroplasty. The use of stems is required for the fixation of the components of the Semi-Constrained (SC), Rotating Hinge (RH), and Total Hinge (TH) systems. This manual describes the intramedullary implantation technique for the Semi-Constrained (SC) components and for the Rotating Hinge and Total Hinge (RH and TH) components. The existing Unconstrained (UC) version with the "Fix", "Mobile", and "Deep Dish" insert options has been expanded to include the Semi-Constrained (SC) design. Rotating or Total Hinge (RH, TH) designs are also available with two knee axis versions to address high-grade instability. Consistency MAXIMUM FLEXIBILITY AND EFFECTIVENESS Compatibility between systems and modularity Freely selectable degree of constraint and level of stability Efficient modular implant system Uncompromised stability STABLE AND RELIABLE RESTORATION OF JOINT KINEMATICS Joint stability over the entire weight-bearing articulation No compromise between congruence and freedom of motion Excellent abrasion behaviour Efficience EFFICIENT AND PRECISE SURGICAL TECHNIQUE: Primary implantation Soft-tissue based surgical technique with constant monitoring of joint space Precise balance of joint space in extension and flexion prior to the first osteotomy No distal reference osteotomy, secondary resection largely avoided Revision Stable and efficient setup for revision cases Joint line reconstruction with reference stems Joint space in extension and flexion balanced prior to the first osteotomy
