Open Surgical Treatment for Femoroacetabular Impingement in Patients over Thirty Years: Two Years Follow-up Results.

PURPOSE

We report short term results of open surgical treatment for symptomatic femoroacetabular impingement (FAI) in patients over the age of 30 years.

MATERIALS AND METHODS

Between May 2011 and June 2012, thirteen FAI hips (11 patients) with hip pain persisting longer than 6 months were treated by either surgical hip dislocation (SHD) or anterior mini-open. They were followed up for longer than 2 years. The 11 patients included 7 females and 4 males with a mean age of 45 (range, 33-60) years. They were clinically evaluated for modified Harris hip score (MHHS) and University of California at Los Angeles (UCLA) activity level. Their lateral center-edge angle, acetabular index, and alpha angle were measured and compared.

RESULTS

Acetabuloplasties were performed for seven cases. Femoral osteochondroplasty was performed for all thirteen cases. At minimum follow-up of two year (range, 24-29 months), all patients had substantial relief in preoperative pain with improvement in range of motion. The median MHHS was significantly (P<0.05) improved from 61 points preoperatively to 87 points at the last follow-up. The median UCLA activity level was 7 (range, 5-8) at last follow-up. Radiological indices improved. Two cases showed mild residual pain attributable to adhesion between capsule and reshaped femoral head-neck area.

CONCLUSION

Open surgical treatment of FAI was a reliable and effective treatment method in symptomatic FAIs for patients over the age of 30 years without advanced arthritic change of hip joint at short term follow-up.
