Patients with relative femoral retroversion may experience less improvement after FAI surgery
Recently published data demonstrated that, although arthroscopic femoroacetabular impingement surgery produced clinically important improvements in all patients, patients with relative femoral retroversion experienced less improvement than those with normal or increased femoral version.
Researchers utilized a prospective hip arthroscopy registry to evaluate 243 patients (mean age: 29.2 years) who underwent arthroscopic surgery for femoroacetabular impingement (FAI). The mean follow-up period was 21 months.
Utilizing the modified Harris Hip Score (mHHS) and Hip Outcome Score (HOS) Activities of Daily Living (ADL) and Sports subscales, the researchers assessed patient-reported outcomes and disease-specific outcomes. Additionally, the researchers used the International Hip Outcome tool (iHOT-33) to determine any disease impact on quality of life.
The researchers classified femoral version as normal (between 5° and 20°) in 149 patients, increased (>20°) in 57 patients and decreased (<5°) in 37 patients. A difference in FAI distribution was observed in the increased version group, with fewer isolated cam procedures but more isolated rim procedures compared with the other version groups.
According to the researchers, there were significant improvements observed in all patient outcome measures. Mean improvement in mHHS was 20 points and mean improvement in HOS-ADL was 15 points. Additionally, the mean improvement observed in HOS-Sports was 23 points, and the mean improvement in iHOT-33 was 23 points.
After stratifying the data by femoral version, the researchers found postoperative improvements seen in the patients with relative femoral retroversion were clinically important but were significantly smaller than those seen in the other groups. - by Monica Jaramillo
