Outcomes of Hip Arthroscopy in Patients With Previous Lumbar Spine Surgery: A Matched-Pair Controlled Comparative Study With Minimum Two-Year Follow-Up

Abstract

Purpose: The purpose of this study was to conduct a matched-pair analysis to determine the effect of prior lumbar spine surgery (LSS) on clinical outcomes of hip arthroscopy.

Methods: Data were prospectively collected on all patients undergoing hip arthroscopy during the study period from April 2008 to December 2012. Patients were excluded if they had previous hip conditions or had undergone prior hip surgery. Patients in the LSS group (history of LSS) were matched in a 1:1 ratio to a control group (no history of LSS) according to age ±5 years, gender, body mass index categories, Tönnis grade, and labral treatment. The following outcomes were recorded in each group: modified Harris Hip Score, Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale, Hip Outcome Score-Activities of Daily Living, and visual analogue scale (VAS) score for pain, patient satisfaction, and rates for revision hip arthroscopies and conversion to total hip arthroplasty (THA).
