Femoroacetabular impingement (FAI) is a common cause of hip pain, and open surgical approaches remain an important treatment option for FAI. This systematic review of the literature sought to determine what post-operative radiographic outcomes have been reported following open surgical correction of FAI. After screening and full-text review, 18 studies involving 1192 hips in 1084 patients were included for analysis. In total, 24 radiological outcomes were reported. CAM-type FAI was most frequently assessed using the alpha angle (61.1 %) and head-neck offset/head-neck offset ratio (33.3 %). Lateral center edge angle (27.8 %) and the acetabular index (22.2 %) were the most commonly reported outcomes for pincer-type FAI. The results of this review suggest that reporting of post-operative radiographic outcomes is variable, that no single radiographic parameter is optimal, and that the clinician must use a combination of reproducible measurements, together with their clinical examination, to confirm adequate restoration of normal hip morphology.

Femoroacetabular impingement (FAI) is a condition increasingly being recognized as a cause of hip pain and disability. Hip arthroscopy is a common method used to treat this condition. The purpose of this review was to identify reported radiographic outcomes after arthroscopic surgery for FAI. Online databases (PubMed, EMBASE, and Medline) were screened for studies involving arthroscopic management of FAI. Full-text reviews of eligible studies were conducted. We identified 23 eligible studies involving 1348 patients from an initial screen of 1304 studies involved. There were 15 different radiographic parameters among the 23 studies. The most commonly reported radiographic outcomes included the alpha angle (69.6 %), center edge angle (34.7 %), and femoral offset ratio (17.4 %). This study highlights the significant variation in reported radiographic outcomes after arthroscopic FAI surgery. [ABSTRACT FROM AUTHOR]
