The VersiTomic ACL Flexible Guide Pin (234‑108‑200) is an integral component in the Stryker VersiTomic flexible reaming system, designed to improve anatomic ACL (and sometimes PCL) reconstruction by enabling surgeons to create femoral sockets/tunnels more flexibly (i.e. with less need to hyperflex the knee). The flexible pin, thanks to its shape memory alloy construction, can navigate through curved guides or offset portals, bending as needed inside the joint and then returning to a straighter configuration as it exits, providing a stable track over which to pass the flexible reamer. The trocar‑style tip is meant to ease penetration through bone/cortical surfaces when creating the start point. The markings on the pin help with measuring tunnel length, ensuring that the surgeon can monitor how much has been advanced, avoid over‑penetration, and select appropriate reamer depth.

Because it is designed to work with the flexible reamer shaft and AM‑guides (or other portal / aiming tools), the guide pin helps maintain the intended trajectory and helps protect cartilage, posterior wall, and other delicate anatomy. It supports precise positioning of the reamer and therefore more reproducible tunnel placement. In ACL reconstruction, especially when placing the femoral tunnel via an anteromedial portal (or offset guides) the flexible nature of the pin helps avoid the geometric constraints and soft tissue impingement that can occur with rigid pins, and helps surgeons avoid having to hyperflex the knee, which can improve visualization, reduce risk to surrounding structures, and surgeon ergonomics.

On the other hand, because the pin is flexible (and small in cross section compared to rigid guide pins), there are trade‑offs: it is more susceptible to bending or wobble if not properly supported, or if the guide mechanism is loose. Also, stressing the pin by trying to force a reamer or failing to maintain alignment can lead to fatigue or even breakage. Indeed, there are adverse event reports of the pin fracturing inside bone (e.g. in MAUDE: a report of a VersiTomic ACL flexible guide pin (#234‑108‑200) breaking inside the patient during surgery). This underscores the importance of careful surgical technique, ensuring good visualization, using appropriate portals and guides, confirming that the pin driver is close to the pin to reduce unsupported span/wobble, and not applying excessive lateral force or bending beyond the intended curvature.
