Hip Arthroscopy: Diagnostic Injections Do Not Predict Surgical Outcomes

A commonly used technique for evaluating complicated hip injuries may not accurately predict surgical outcomes, according to new research presented at the American Orthopaedic Society for Sport’s Medicine’s Specialty Day. The study sought to determine if the amount of pain relief from a preoperative diagnostic intra-articular (IA) injection correlated with patient outcomes following surgery for femoroacetabular impingement (FAI). The findings were that the amount of pain relief from an IA injection is a poor predictor of short-term positive outcomes.

The research team at the Mayo Clinic in Rochester, Minnesota, analyzed records of 96 patients who were undergoing hip arthroscopy for FAI from 2007 to 2012. The team found no significant difference in the outcome scores for individuals with greater than 50% pain relief on preoperative diagnostic injection compared to patients who experienced less than 50% pain relief. The researchers noted the value of identifying viable tools for surgical selection and treatment decisions and recommended further research in this pursuit.
