Early Clinical Results of Surgical Treatment of Patients with Femoroacetabular Impingement

Abstract

Introduction Surgical treatment is the treatment of choice in patients with symptoms and radiological signs of femoroacetabular impingement.

Objective Our experience and early results of surgical treatment of patients with signs of femoroacetabular impingement and early hip osteoarthritis are reported.

Methods The results of treatment of 21 patients aged 23-54 years with different types of femoroacetabular impingement are presented. Safe open surgical dislocation of the hip was performed in all patients. Before and after surgery, the WOMAC score was performed, clinical and radiographic data of the operated hips were evaluated and t-tests were used for statistical analyzes of data.

Results The WOMAC score improved from 70.5 points ( range 56.3 to 89.8 points) to 90.3 points (range 70.3 to 100 points) at one year of follow-up (p<0.0001), anterior impingement test was negative in all operated cases, average hip internal rotation improved significantly, no complications were found, except trochanteric nonunion at the site of osteotomy, which was reaffixed.

Conclusion Postoperative results have shown that the surgical approach to treating patients with femoroacetabular impingement is the method of choice. Three operated patients, with advanced osteoarthritis of the hip, had to be converted to total hip replacement.
