The Association of Preoperative Hip Pain Duration With Delayed Achievement of Clinically Significant Outcomes After Hip Arthroscopic Surgery for Femoroacetabular Impingement Syndrome

摘要

Background: Patients with hip pain >= 2 years before hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS) have been shown to achieve inferior short-term and midterm outcomes compared with patients with a shorter pain duration, although there is limited literature that has evaluated the time to achieve clinically significant outcomes (CSOs) in this population. Purpose: To compare the time to achieve CSOs after hip arthroscopic surgery for FAIS in patients with and without prolonged hip pain and to identify independent predictors of the delayed achievement of CSOs. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent primary hip arthroscopic surgery for FAIS between January 2012 and July 2019 with 6-month, 1-year, and 2-year Hip Outcome Score-Activities of Daily Living (HOS-ADL) and Hip Outcome Score-Sports Subscale (HOS-SS) scores were identified. Patients with prolonged hip pain (preoperative duration >= 2 years) were propensity score matched to a control group (preoperative duration = .488) with similar baseline HOS-ADL and HOS-SS scores (P >= .971). The prolonged hip pain group showed delayed achievement of the minimal clinically important difference and Patient Acceptable Symptom State for both the HOS-ADL and HOS-SS on Kaplan-Meier analysis (P = 2 years was shown to be an independent predictor of the delayed achievement of CSOs, with hazard ratios ranging from 1.32 to 1.65 (P = 2 years was an independent predictor of the delayed achievement of CSOs after primary hip arthroscopic surgery for FAIS.
