Background:
Capsular closure in FAI patients during hip arthroscopy procedures are
still debated. The Danish Hip Arthroscopy Registry (DHAR) contains data to perform
matched- cohort analyses.
Purpose / Aim of Study:
The purpose of this study was to describe data from DHAR
after FAI surgery associated with capsular closure, report outcome data and compare
these outcome data with a matched-cohort study group. Our primary hypothesis was
that patients undergoing hip arthroscopy would not benefit in subjective outcome from
capsular closure compared with no closure.
Materials and Methods:
We identified FAI patients in DHAR where the capsule was
closed during the hip arthroscopy. A matched cohort of patients who did not have cap-
sular closure performed were selected. Matching criteria were age, gender, radiological
parameters (lateral centre edge angle and alpha angle). We compared the two groups
according to HAGOS, HSAS, EQ-5D and VAS. We identified 247 patients in each group.
Findings / Results:
Both groups improved significantly in all postoperative PROMs
at one and two year follow-up. When comparing the improvements between the two
groups we found a significant better improvement in the capsular closure group in VAS
and all HAGOS sub scales at both one and two year follow-up. HSAS demonstrated im-
provement in the closure group at one year but no difference at two year follow-up.
EQ-5D showed difference at two year follow-up.
Conclusions:
This study showed that FAI-patients undergoing capsular closure during
hip arthroscopy had a significant improvement in outcome when compared to a matched
control group at two year follow-up. We also found improvement in physical activity and
quality of life scores. We therefore conclude that capsular closure might positively affect
the outcome in FAI-patients during hip arthroscopy.
