Outcome of arthroscopic treatment for symptomatic femoroacetabular impingement

Abstract

Background: Recently, arthroscopic-based treatment for hip-related pain with radiological findings of femoroacetabula impingement and labral lesions has been developed We aim to present clinical outcome in a single centre patient cohort of patients treated arthroscopically for hip-relate pain due to femoroacetabular impingement Methods: A total of 117 consecutive patients operated in 2009-2011 were included in this prospective case serie (41% male; mean age 37 years; (range 15-70). The indication for arthroscopic treatment of hip-related pain wa mechanical hip symptoms and radiological findings of femoroacetabular impingement To evaluate hip function and pain level at 1-year and 2-5 years follow up (FU) mHHS (Modified Harris Hip Score) HOS (Hip Outcome Score) and a Numeric Rating Scale (NRS) pain score were used Results: Labral tears were seen in 91% of the hip arthroscopies. Cartilage lesions (ICRS grade 2 and above) were seen a the acetabular and femoral articular surfaces in 79% and 15% of cases, respectively. The therapeutic procedures were i 99% of the arthroscopies osteochondroplasty and/or acetabular rim-Trimming. In 77% of procedures labral reattachmen was performed. The patient evaluated outcome demonstrated significant increases in mHHS and HOS at 1-year follo up and at final FU compared to preoperatively (1 yr: mHHS: 72.1 to 85.3, HOS: 71.4 to 85.1; final FU: mHHS: 72.1 to 83.8 HOS: 71.4 to 83.7). Pain levels decreased significantly from preoperatively to follow ups. Five patients underwent total hi replacement within the follow up period after hip arthroscopy Conclusions: Arthroscopic treatment of femoroacetabular impingement improves patient evaluated outcomes. Furthe studies are needed to determine failure rates and risk factors.
