OsseoTi® Tibial Sleeves


The Vanguard® 360 OsseoTi Tibial Sleeves are designed to treat tibial defects that are often encountered during revision knee surgeries. These sleeves offer BONE SPARING options that include a range of half and full sleeves, designed to increase component fixation in the metaphyseal region.


The half sleeves can be utilized separately, together or in conjunction with a block augment.  These sleeves can be positioned independently or symmetrically within the tibia resulting in a highly effective bone conserving defect filling solution.  The full sleeve option offers ease of use when a symmetrical defect is present.

In revision, balancing optimal coverage and rotation can be difficult and time consuming.  When utilizing the OsseoTi Tibial Sleeves, which offer three offset options, an optimal balance between coverage and rotation is achieved.


Tibial loosening, which has become the leading failure mode in revision knee surgeries3, can now be addressed with the OsseoTi Tibial Sleeves. Cavitary defects normally found in revision knee procedures can also be addressed due to the variety of sizing and positioning options of the OsseoTi Tibial Sleeves. Utilizing a typical highly vascularized metaphyseal region4 of the tibia, these sleeves are designed to distribute the load through biologic fixation from the tibial plateau and stem to loads closer to the joint.  

Fully Instrumented Technique

The Vanguard 360 Tibial Sleeve surgical preparation is a simple, intuitive instrument system that allows the surgeon to position the tibial component for optimal placement, while offering offset options, if needed. This technique ensures that the sleeve does not drive the placement of the tibia.
