However, the impact of preoperative hip osteoarthritis severity on quality of life (QoL) post-surgery remains unclear. This study tested the hypothesis that individuals with moderate-to-severe hip osteoarthritis would show smaller QoL improvement over two-years compared to those without or mild hip osteoarthritis.METHODS: In this retrospective cohort study, 259 patients diagnosed with FAIS were included from a single orthopaedic clinic. Participants were categorized based on hip osteoarthritis severity using the Kellgren and Lawrence grade (KLG), with 147 classified as having no hip osteoarthritis (KLG=0), 77 with mild osteoarthritis (KLG=1), and 36 with moderate-to-severe osteoarthritis (KLG≥2 (72% KLG=2, 25% KLG=3, 3% KLG=4)). QoL was assessed pre-operatively and at multiple post-operative time points using the 33-item International Hip Outcome Tool (iHOT-33). Linear mixed effects modelling assessed QoL changes over two-years.RESULTS: All groups, regardless of hip osteoarthritis severity, demonstrated statistically significant improvements in iHOT-33 scores over two-years postoperatively (p<0.001, d=0.20-0.79). Patients without hip osteoarthritis (β=0.32, 95%CI: 0.01:0.64, p=0.049) and those with mild osteoarthritis (β=0.28, 95%CI: 0.04:0.52, p=0.031) showed steady improvements in QoL. Conversely, those with moderate-to-severe osteoarthritis exhibited more limited QoL improvement (β=0.05, 95%CI: -0.14:0.23, p=0.452).CONCLUSIONS: Pre-operative hip osteoarthritis severity influenced postoperative QoL outcomes following hip arthroscopy in individuals with FAIS. Individuals without or with mild hip osteoarthritis experience more consistent QoL improvements over two-years compared to those with moderate-to-severe osteoarthritis. These findings highlight the importance of tailoring treatment strategies and managing patient expectations based on hip osteoarthritis severity.LEVEL OF EVIDENCE: Level III (Observational Studies).PMID:41314341 | DOI:10.1016/j.jisako.2025.101044
