超出期望。保持积极的生活方式
JOURNEY◊II XR addresses patients' ever-growing expectation to return to an active lifestyle that is designed to:
- Retain the ACL in a total knee replacement
- Deliver normal proprioception and muscle control1
- Complete the JOURNEY II platform
Preserve the ACL, and get patients back to their normal kinematics with the revolutionary JOURNEY II XR.

Highlights of the JOURNEY II XR system include:
- A femoral component that is shared with JOURNEY II CR
- A tibia component that includes a metal tibia tray with two independent and uniquely designed medial and lateral inserts
- A seamless transition from:JOURNEY II XR (ACL/PCL Retaining) JOURNEY II CR (PCL Retaining) JOURNEY II BCS (ACL/PCL Sacrificing)
Indications of JOURNEY II XR
使用适应症包括类风湿关节炎；创伤后关节炎，骨关节炎或退行性关节炎；失败的骨质或单室替代。该系统设计用于患者中的主要全膝关节置换手术，那里的韧带和副物质仍然完好无损。
Designed to replicate normal knee motion, the JOURNEY II XR prosthesis provides more mobility in the lateral compartment than other total knee systems.1 For patients that present with significant varus or valgus deformities (> 15º), morbid obesity or deficient cruciate ligaments, consider whether additional implant constraint is more appropriate. If patients with the above mentioned conditions are scheduled for a JOURNEY II XR then consider having a more constraining (CR, Deep Dished or BCS) implant option on hand.
Contraindications
1. Cases where there is poor bone stock which would make the procedure unjustifiable.
2. Active, local infection or previous intra-articular infections.
3. Mental or neurologic conditions that tend to pre-empt the patient’s ability or willingness to restrict activities.
4. Neuropathic (Charcot) joint.
5. Conditions that tend to place increased loads on implants such as age, weight, and activity level, which are incompatible with a satisfactory long-term result.
6. Collateral ligament insufficiency (except in cases where a constrained knee system is indicated and used).
7.骨骼不成熟。
8. Use of a supracondylar nail through intercondylar notch of PROFIX™ primary femoral components.
9. Use of slotted femoral and tibial stems without adequate bone support.
10. Anterior cruciate ligament insufficiency when using the JOURNEY II XR tibial base and inserts.
11. Incomplete or insufficient tissue surrounding the knee.
12. Use of a supra-patellar tibial nail through cruciate notch of JOURNEY II XR tibial baseplate.
Note: Improper technique can result in ACL impingement or failure or eminence fracture. Take care to ensure the ACL and other soft tissues are not damaged throughout the procedure.
