A3GT Knee system
About the A3GT knee system
The A3 GT Knee is a fourth-generation Total Knee System first implanted in 2012, benefitting from an anatomic tibia which permits both improved cortical coverage and rotational alignment, a large range of sizes for best anatomical fit, soft tissue friendly high flex femoral component and highly engineered instrument system to support accurate and reproducible alignment.
Key features of the A3GT Knee System
- 12 Sizes of Femur and Tibia
- High flex femoral design
- Soft tissue friendly patello-femoral articulation
- Asymmetric tibial tray for enhanced coverage and optimal rotational position
- 4 levels of constraint (CR, AS, PS and PS+)
- Intuitive and innovative instrumentation
- 3 tray system supports all knee variations (excluding patella)
The instrument system is precision engineered to permit anterior, posterior or mixed referencing, at the same time allowing excellent rotational alignment from the anatomic tibial component. Thus the A3 GT can be implanted with either Mechanical or Anatomic Alignment, and with respect to both good cortical fit and kinematic principles.

Real surgeons, real expertise, real results
JRI’s implants are excellent—the precision and quality stand out in every procedure. Their team’s clinical guidance and detailed resources have been a game-changer for ensuring the best outcomes for my patients.
Dr. Emily Chen | Orthopaedic Surgeon
After my hip replacement with JRI products, I regained my mobility faster than I expected. The quality of the implant is clear, and knowing it was UK-made gave me extra confidence in my care.
Jacob R | Patient
Our team benefited immensely from JRI’s tailored training sessions. The practical approach and expert-led instruction have improved our efficiency and teamwork in theatre. Highly recommended for any healthcare professionals looking to refine their skills.

ABM Modular Revision Femoral Stem
The ABM Modular Revision Femoral Stem is based on the design of the successful Wagner style prosthesis. 8 longitudinal ridges in the distal stem aid preservation of the cancellous bone, maintain rotational stability and provide additional strength to the implant itself.
