Purpose Chronic ankle instability is the main complication of ankle sprains and requires surgery if non-operative treatment fails. The goal of this study was to validate a tool to quantify psychological readiness to return to sport after ankle ligament reconstruction. Methods The form was designed like the anterior cruciate ligament-return to sport after injury scale and “Knee” was replaced by the term “ankle”. The ankle ligament reconstruction-return to sport after injury (ALR-RSI) scale was filled by patients who underwent ankle ligament reconstruction and were active in sports. The scale was then validated according to the international COSMIN methodology. The AOFAS and Karlsson scores were used as reference questionnaires. Results Fifty-seven patients (59 ankles) were included, 27 women. The ALR-RSI scale was strongly correlated with the Karlsson score (r = 0.79 [0.66–0.87]) and the AOFAS score (r = 0.8 [0.66–0.87]). A highly significant difference was found in the ALR-RSI between the subgroup of 50 patients who returned to playing sport and the seven who did not: 68.8 (56.5–86.5) vs 45.0 (31.3–55.8), respectively, p = 0.02. The internal consistency of the scale was high (α = 0.96). Reproducibility of the test–retest was excellent (ρ = 0.92; 95% CI [0.86–0.96]). Conclusion The ALR-RSI is a valid, reproducible scale that identifies patients who are ready to return to the same sport after ankle ligament reconstruction. This scale may help to identify athletes who will find sport resumption difficult. Level of evidence III.

The success of percutaneous fixation of non or minimally displaced scaphoid waist fractures is reliant on optimal placement of the screw. This can be challenging for surgeons to achieve, potentially involving a large volume of intraoperative imaging, and surgical time. Mixed reality (MR) is a new technology that allows the projection of holographic imagery within the surgeon’s field of vision intraoperatively. This imagery can include surgical planning data and 3D reconstructions of a patient’s anatomy that can be used in order to aid the surgeon in achieving accuracy. We describe a technique for how this novel technology might be used in the future to fix scaphoid fractures—MR assisted percutaneous scaphoid fixation. This is done using cadaveric modeling. MR assisted percutaneous scaphoid fixation may have the potential to aid surgeons in achieving an optimal guidewire placement with the ability to reduce surgical time and radiation exposure.
