Abstract

Background: Outcome studies assessing a cohort of patients receiving microfracture in the hip have focused on second look arthroscopy and return to sport, which have shown favourable results in the absence of osteoarthritis. Few studies exist focusing on clinical outcomes after microfracture in the hip using patient reported outcome (PRO) scores. The purpose of this study is to evaluate two-year clinical outcomes of a series of patients treated with microfracture during arthroscopic hip surgery using PRO scores. Methods: During the study period, all workers’ compensation (WC) and non-WC patients treated with microfracture during arthroscopic hip surgery were included. Four PRO scores, pain scores and satisfaction were used to assess clinical outcomes. Any revision surgeries or conversions to total hip arthroplasty (THA) were noted. Location of microfracture procedure, lesion size and additional variables assessed survivorship. Results: Thirty-seven cases met the inclusion/exclusion criteria, of which 30 patients (30/37, 81%) were available for minimum two-year follow-up. Twenty-six patients were classified as survivors. Preoperative scores for patients with WC status were lower than non-WC patients and statistically significant (p<0.5) for three of the PROs. However, changes in all four PRO measurements demonstrated statistically significant improvements from preoperative to two-year follow-up for both compensation groups (p<0.05). The amount of change in PRO scores for both compensation groups was similar and not statistically significant. Two patients required THA and two patients required revision arthroscopy. Conclusion: Our study demonstrates statistically significant clinical improvement in PRO’s after receiving microfracture during arthroscopic hip surgery at minimum two-year follow-up.
