Based on the design of the MRP-TITAN system, the KAM-TITAN knee arthrodesis system is available in anatomic left and right variants in addition to a neutral module. With its integral 6° valgus and 7° flexion angles, the implant system restores the physiologic axis of the leg. For the patient this means a high degree of comfort, high initial stability for immediate weight bearing, and mobilization as early as possible. Some patients have extremely poor bone stock with minimal opportunity for bony ingrowth. Even in such a situation, the fixation stems and knee arthrodesis module can achieve a secure positive locking connection between the thigh and lower leg.
