Fixation of Ankle Syndesmotic Injuries: Comparison of TightRope Fixation and Syndesmotic Screw Fixation for Accuracy of Syndesmotic Reduction
Ankle syndesmotic injuries are complex and require anatomic reduction and fixation to restore the normal biomechanics of the ankle joint and prevent long-term complications.
The results of this study indicate that fixation with TightRope provides a more accurate method of syndesmotic stabilization compared with screw fixation. Syndesmotic malreduction is the most important independent predictor of clinical outcomes; therefore, care should be taken to reduce the syndesmosis accurately.

Metatarsophalangeal Joint Pathology in Crossover Second Toe Deformity A Cadaveric Study
Ligamentous and capsular insufficiency of the second metatarsophalangeal joint has been surgically treated for over two decades, mainly with indirect surgical repairs, which stabilize adjacent soft tissue and shorten or decompress the osseous structures. While ligamentous insufficiency has been described and recognized, degeneration of the plantar plate and tears of the capsule have rarely been documented.
In this largest series of cadaveric dissections of crossover second toe deformities, we describe the types and extent of plantar plate tears associated with increasing deformity of the second ray. We present, based on these findings, an anatomic grading system to describe the progressive anatomic changes in the plantar plate.

Tibial Fixation Properties of a Continuous-Loop ACL Hamstring Graft Construct with Suspensory Fixation in Porcine Bone
Smith et al compared Arthrex® TightRope Attachable Button System (ABS) fixation of the GraftLink ACL construct to standard interference screw (IF) fixation.1 The TightRope/GraftLink construct outperformed IF screw fixation in both yield and ultimate load and was statistically equivalent in cyclic displacement. The GraftLink technique not only increases tibial fixation strength but allows for greater graft diameter, eliminates foreign bodies in the tibial and femoral socket, allows continued graft tensioning after fixation is complete and facilitates an all-inside technique.
