Medical NLP (MedNLP) methodologies perform well with limited data availability.</p><p><strong>Objectives: </strong> We present the outcomes of the Real-MedNLP workshop, which was conducted using limited and parallel medical corpora.

Patellofemoral joint regions of interest were identified using an automated landmark detection tool (BoneFinder) on lateral knee X-rays. An end-to-end deep learning method was developed for predicting PFOA progression based on imaging data in a five-fold cross-validation setting.
