Twistr™ Retrograde Reamer and CRUCIATE+ Instrument System

The TWISTR™ Retrograde Reamer ("Retroreamer") is a disposable outside-in retrograde reamer that consists of a drill pin with deployable blade and an outer sleeve with graduated markings. The TWISTR Retrograde Reamer can accommodate a range of diameters (6-12mm in half millimeter increments) in a single device. The outer sleeve is curcumferentially laser marked in 5 mm increments to assist in measuring tunnel depth.

Surgeons performing cruciate ligament reconstructions desire anatomic tunnel placement, which can be difficult to achieve with inside-out drilling techniques. The one-size-fits-all TWISTR Retrograde Reamer & Criciate + Instruments enable precision, outside-in tunnel drilling, while removing the need to hyper-flex the knee and reducing the risk of condylar damage during drilling.
