Pre-operative intra-articular hip injection as a predictor of short-term outcome following arthroscopic management of femoroacetabular impingement.

Purpose Diagnostic hip injections are often used to confirm intra-articular pathology prior to arthroscopic treatment for femoroacetabular impingement (FAI). However, little is known whether the type of response correlates with the post-operative functional outcomes. The purpose of this study is to document the ability of a diagnostic hip injection to predict short-term functional outcomes following arthroscopic surgical management.
