The Zimmer Unicompartmental High Flex Knee System is designed to provide an early intervention option for patients with unresolved medial or lateral compartmental arthritis. Based on the successful design of the M/G® Unicompartmental Knee, the Zimmer Unicompartmental High-Flex Knee combines implant and instrument innovations with proven design concepts to create a reproducible knee system for today’s active patient population.
The Zimmer Unicompartmental High Flex Knee System is based on the established implant design of the M/G Unicompartmental Knee System, which has more than 15 years of clinical success.2 The combination of these proven design concepts and several new design innovations is already showing a reduced rate of revision in the Australian Orthopaedic Registry.

The Zimmer Unicompartmental High Flex Knee unites the proven design concepts of the M/G Uni with several new design innovations to meet the demands of today’s active patient.
Extended Posterior Condyle
Safely accommodates high flexion up to 155°
Round on Flat Articulation
Eliminates implant constraint and allows for +/- 8° of varus/valgus tilt without femoral point-loading on the polyethylene
Two Optimally Positioned Femoral Pegs
Femoral peg location changes by size for optimal fixation
Three Points of Tibial Fixation
Two hourglass pegs and a rotational fin create a strong foundation for tibial fixation
Seven femoral sizes, six tibial sizes, and tibial size specific articular surfaces in 1mm increments
Anatomically shaped tibial and femoral components are designed to replicate the natural anatomy
The Zimmer Unicompartmental High-Flex Knee System adapts to a range of surgical approaches to satisfy specific surgeon preferences. This is accomplished with a single system of instruments that can be used with a spacer block, intramedullary, or extramedullary approach.
The Zimmer Unicompartmental High Flex Knee may also be used with the Gender Solutions® PFJ System giving the freedom to perform medial, lateral, and bi-compartmental surgical procedures.
