Video Summary

The video explains that patellar dislocation, which accounts for 2-3% of knee presentations, has well-established risk factors such as young age, trochlear dysplasia, and high-demand activities. However, accurately predicting recurrent instability after a first-time dislocation remains difficult. The study aimed to create a prognostic tool for predicting recurrent instability by analyzing the clinical history of primary lateral patellar dislocations and determining long-term predictors. They used the Rochester Epidemiology Project to access medical records from 1990-2010 and reviewed 81 patients with a mean follow-up of 10 years. The results led to the creation of the Rochester Instability Prognostication Score (RIP score), which classifies patients into low, intermediate, and high-risk categories based on age, skeletal maturity, trochlear dysplasia, and a specific measurement. The score demonstrated satisfactory prognostication ability and is available for clinical use online.
