Functional outcomes and 8-year survival after hip arthroscopy in patients with degenerative hip disease

Background and purpose The purpose of this study is to identify which variables may have a significant impact in mid-term survivorship following hip arthroscopy. Methods This a single-centre single-surgeon retrospective study including 102 patients who underwent a hip arthroscopy procedure between August 2007 and October 2011. Each subject completed three questionnaires at final follow- up: “Hip "Outcome Score-Activities of Daily Living" (HOS-ADL), "Hip Outcome Score-Sport" (HOS-S) and " Modified Harris Hip Score “(m-HHS). Results Thirty-nine patients (40 hips) were finally included in our study. Mean age was 43.1 ± 9.9 years with a three-year minimum follow-up (75.43 ± 25.2 months). Younger patients and those with a shorter duration of symptoms obtained significantly higher HOS-S and m-HSS scores. Patients who had undergone previous lumbar spinal surgery obtained significantly worse HOS-ADL scores. Patient acceptable symptom state (PASS) was achieved in 23 patients (57.5%) for m-HHS, 22 patients (55%) for HOS-ADL and 25 patients for HOS-S scores. No major complication was observed. Only four patients had minor complications. Mean survival time was 97.1 months (95% CI, 85.1–109.1 months), with a survival at 8 years of 69% (95% CI, 53%–85%). Conclusions Our findings suggest that hip arthroscopy is a safe procedure with acceptable functional outcomes after a long follow-up. Care should be taken when treating patients with prior lumbar surgery. Level of evidence Level IV. Case series.
