Abstract
Abstract Introduction This study aimed to provide a descriptive review of all cases recorded in the UK Non-Arthroplasty Hip Registry (NAHR) and to assess trends in patient demographics, patient-reported outcome measures (PROMs) and procedure details, with specific focus on hip arthroscopy (HA) for femoroacetabular impingement (FAI) and periacetabular osteotomy (PAO). Methods All cases recorded in the NAHR up to December 2024 were identified. Data was analysed for the entire cohort, as well as in groups of 1000 in chronological order to assess for temporal trends. iHOT-12, EQ-5D Visual Analogue Scale (VAS) and EQ-5D Index scores were assessed. Temporal trends were assessed using linear (LR) and Poisson regression (PR), as well as Jonckheere-Terpstra (JT) testing. Results 11465 cases were identified. 11 groups of 1000 cases were created, in chronological order. Total median age and BMI were 33 and 25.0 respectively. 63.0% of cases were female. Mean pre-operative PROMs were 32.3±18.0 for iHOT-12, 66.1±21.0 for EQ-5D VAS and 0.50±0.25 for EQ-5D Index. The most commonly-recorded procedure was HA for FAI (66.9%, n=7672), followed by PAO (12.6%, n=1445). 83.4% (n=9542) of cases were arthroscopic and 15.7% (n=1797) were recorded as open. Temporal trend analysis demonstrated a statistically significant decrease in age (LR -0.0889, p=0.0063), pre-operative EQ-5D VAS (-0.2325, p=0.0011, JT p<0.0001) and a non-significant trend in EQ-5D Index (-0.0016, p=0.0607, JT p=0.0013) with time. A significant increase in BMI (LR 0.0572, p=0.0014) and pre-operative iHOT-12 (0.4295, p<0.0001, JT p<0.0001) were noted. Numbers of HAs performed for FAI decreased significantly from 2014-2024 by an estimated 16.5% (PR -0.017619, p<0.0001) whilst PAOs increased by an estimated 138% from 2012-2024 (PR 0.0873, p<0.0001). FAI trend analysis demonstrated a significant increase in pre-operative BMI (LR 0.0644, p=0.0020) and iHOT-12 (0.4840, p<0.0001) and a significant decrease in EQ-5D VAS scores over time (-0.2528, p=0.0038). JT analysis of EQ-5D Index was significant for a negative temporal trend (p=0.0214), but this was non-significant on LR (p=0.223). PAO trend analysis demonstrated a significant decrease in patient age (-0.1925, p=0.0101) and a significant increase in pre-operative iHOT-12 score (0.3562, p=0.0348). Conclusion This study has demonstrated trends towards decreasing caseload of HAs for FAI and increasing caseload of PAO for DDH. Patients undergoing these procedures have demonstrated modest but significant trends towards greater pre-operative iHOT-12 scores, suggesting less severe hip pathology at time of intervention. This study has evaluated the current patient cohort recorded in the NAHR.
