“…However, the increase in extrusion index of participants in this study was not significant (P = .107). 18 Haug et al 19 also found a statistically significant decrease in alpha angle measurements of post-arthroscopy patients. 19 LCEA is associated with acetabular over-coverage and values greater than 39° indicate pincer-type impingement.…”

Aims: To compare (a) the change in radiological bony morphology between participants with femoroacetabular impingement (FAI) syndrome who underwent arthroscopic hip surgery compared to physiotherapist-led non-surgical care and (b) the change in radiological bony morphology between participants with FAI syndrome who underwent arthroscopic hip surgery involving cam resection or acetabular rim trimming or combined cam resection and acetabular rim trimming.Methods: Maximum alpha angle measurements on magnetic resonance imaging and Hip 2 Norm standardized hip measurements on radiographs were recorded at baseline and at 12 months postoperatively. One-way analysis of covariance and independent T tests were conducted between participants who underwent arthroscopic hip surgery and physiotherapist-led non-surgical care. Independent T tests and analysis of variance were conducted between participants who underwent the 3 different arthroscopic hip procedures.
