JOURNEY◊ II UK Unicompartmental Knee System

Built on the heritage of one of the most clinically successful partial knee systems, the JOURNEY II UK has demonstrated excellent early survivorship and high patient satisfaction.1,2

Continuing a winning legacy in partial knee replacement

Every patient deserves a knee that feels normal. Based on the principle that unicompartmental knee arthroplasty (UKA) treats only the affected part of the knee and allows patients to retain healthy ligaments, the JOURNEY II UK System combines clinically successful features and advanced bearing technology in a solution backed by clinical data1,2 and has been shown to deliver improvements in KOOS JR scores.*1

  • Promotes intra-operative sizing flexibility through a range of peg positions and size groupings, with patella-friendly contours designed to maximise freedom in implant positioning3
  • Optimised for conventional instrumentation and compatible with a robotics-assisted approach using the CORI◊ Surgical System
  • When used with the CORI System, surgeons can use the first digital tensioning device to assess joint laxity in the native knee before performing bony resection: the CORI Digital Tensioner4,5

Delivering clinical value

Patients who receive a UKA procedure demonstrate higher levels of patient satisfaction and better outcomes when compared to total knee arthroplasty (TKA).6-14 When performed with robotics-assisted technology, rather than conventional approaches, UKA is shown to offer more accurate and reproducible implant placement.15-20
