Offset-based system
Multiple offset options and body sizes allow fine-tuning of restoring the head center, independent of leg length and canal size.
In one study, the authors concluded “The hybrid Exeter V40 Trident seemed to produce the best overall results”6
In patients over 75 years old, early revision was 9.14x more common in the best three cementless stems compared to the best three cemented stems in the Australian registry.10 In another study featuring 32,644 primary total hip arthroplasties, cementless stems were found 14x more likely to cause intraoperative fractures, and 10x more likely to cause postoperative fractures within 30 days than cemented stems.11
“The Exeter cemented stem has excellent survivorship at minimum 20 years in young patients [107 patients under 55 years of age].”12
“No stem was revised for aseptic loosening in this series [featuring 540 total hip arthroplasties]. The contemporary Exeter V40 stem continues to perform well, and survival has remained comparable with that of the Exeter Universal stem.”13
Mako SmartRobotics combines three key components: 3D CT-based planning, AccuStop haptic technology, and insightful data analytics, into one platform that has shown better outcomes for your total knee, total hip and partial knee patients.7,8,13
Mako SmartRobotics™ with Exeter empowers surgeons to know more through CT based planning, unlocking patient specific planning and robotic-arm assisted execution which is designed to help preserve bone and facilitate precise implant placement for both acetabular and femoral components. This system enables surgeons to more easily tackle muscle-sparing approaches through approach-specific registration.*
*Access to the Mako Program Analytics offering requires execution of a separate Mako Program Analytics agreement.
