Labral preservation and baseline osteoarthritis influence long-term degenerative outcomes after hip arthroscopy for femoroacetabular impingementsyndrome: a systematic review and meta-analysis

Femoroacetabular impingement syndrome (FAIS) is a recognized risk factor for early hip osteoarthritis (OA), and hip arthroscopy (HA) is widely used as a joint-preserving intervention. While short- and mid- term outcomes are favourable, long-term effects of HA on structural degeneration and conversio
