MonoMod stem is the 1st of its kind revision stem in the world, ushering in a new generation of FTT (fluted tapered stems) with significant advantages over earlier designs. The MonoMod revision stem is a third-generation FTT non-cemented revision stem that combines the advantages of the 1st generation Monobloc and 2nd generation modular types of fluted tapered titanium femoral revision stems. 

Fluted Tapered Titanium philosophy is now well established as the gold standard in femoral revisions. However, surgeons continue to have a dilemma in choosing between the Monobloc option and the modular version of FTT for a given clinical situation. Both types of FTT stems bring with them a unique set of advantages as well as disadvantages. 

Monobloc FTT stems are easy to insert and have no risk of breakage but have a higher incidence of subsidence added with an inability to restore soft tissue tension in some cases. In contrast, modular ones are more resistant to subsidence and have a better scope to achieve soft tissue balance. However, they are more cumbersome to insert and have an intrinsic risk of breakage at the junction, especially if the proximal portion is left devoid of bone support. As the MonoMod combines the advantages of both types, it can be used in all situations, eliminating the dilemma in the surgeon’s mind. 

The MonoMod is essentially a monobloc stem but has an option of using proximal femoral augments to achieve secondary fixation in proximal bone without having a weak junction in the stem. In addition, it has various other features enabling reproducible consistent results. This 3rd generation design brings along key innovations to make it extremely surgeon-friendly.
