Comparing the Drop Vertical Jump Tracking Performance of the Azure Kinect to the Kinect V2.

Traditional motion analysis systems are impractical for widespread screening of non-contact anterior cruciate ligament (ACL) injury risk. The Kinect V2 has been identified as a portable and reliable alternative but was replaced by the Azure Kinect. We hypothesize that the Azure Kinect will assess drop vertical jump (DVJ) parameters associated with ACL injury risk with similar accuracy to its predecessor, the Kinect V2.

Should my recommendation letter be written by artificial intelligence?

Letters of recommendation are increasingly important for the residency match. We assessed whether an artificial intelligence (AI) tool could help in writing letters of recommendation by analyzing recommendation letters written by 3 academic staff and AI duplicate versions for 13 applicants. The preferred letters were selected by 3 blinded orthopedic program directors based on a pre-determined set of criteria.

A Prediction Model for Primary Anterior Cruciate Ligament Injury Using Artificial Intelligence.

Background: Supervised machine learning models in artificial intelligence (AI) have been increasingly used to predict different types of events. However, their use in orthopaedic surgery has been limited.

Hypothesis: It was hypothesized that supervised learning techniques could be used to build a mathematical model to predict primary anterior cruciate ligament (ACL) injuries using a set of morphological features of the knee.

Characterization of a Pre-Clinical Mini-Pig Model of Scaphoid Non-Union.

A fractured scaphoid is a common disabling injury that is frequently complicated by non-union. The treatment of non-union remains challenging because of the scaphoid's small size and delicate blood supply. Large animal models are the most reliable method to evaluate the efficacy of new treatment modalities before their translation into clinical practice.

Isolated axillary artery injury due to blunt trauma in ice hockey.

We report the first case of a purely isolated axillary artery dissection because of focal blunt trauma to the axilla. A 42-year-old man presented to our outpatient orthopedic clinic 7 days after a fall during a hockey game whereby another player's skate blade struck the patient directly in the axilla without disrupting the skin. The patient denied having any symptoms of shoulder dislocation but experienced some pain and numbness, which subsided rapidly.
