Aims: We sought to characterize the morbidity upon presentation of GTPS and compared it to patients with end-stage, hip osteoarthritis (OA) awaiting total hip arthroplasty (THA). We hypothesize that patients with GTPS will have similar or worse morbidity than hip OA patients.
Methods: This retrospective case-control study examined patient reported outcomes measures (PROMs) on activity limitations, quality of life, pain, and level of disability, in 156 GTPS patients (193 hips) and 300 pre-THA hip OA patients (326 hips). All patients presented at a single academic medical center. Patients with secondary hip conditions or previous hip surgeries were excluded from the study. PROMs were analyzed using an equivalence test and two-one-sided t-tests.
Results: Equivalence in mean UCLA Activity score between GTPS and OA groups were established with tolerance margin of ± 5. The difference in mean UCLA Activity score was 0.002 (95% CI -0.45 to 0.43, p < 0.01) between GTPS and OA patients. Equivalence in mean VAS score between GTPS and OA were established with tolerance margin of ± 10. The difference in mean VAS score was 0.35 (95% CI -0.86 to 0.16, p = 0.02). HOOSQol score was much worse in GTPS patients, placed well outside of the ± 10 tolerance margin and difference in means score was 1.72 (95% Cl -2.17 to -1.26, p = 0.99).
Conclusion: This cumulative evidence characterizes GTPS as painful and limiting in activities of daily living, as pre-THA hip OA, and with poorer quality of life scores than hip OA. Clinicians and researchers should consider GTPS as seriously as hip OA.
