Key Takeaways
Randomized controlled trial, multicenter study in Denmark
Evaluate the effect of capsular closure on subjective postoperative outcomes and revision rates in patients undergoing hip arthroscopy for FAIS
200 patients with FAIS were randomly assigned to either closure or no closure of the interportal capsulotomy at termination of the arthroscopic procedure.
The capsular closure was performed with 2 to 3 absorbable sutures, using the "Quebec City Slider" knot technique.
The primary outcome was the HAGOS Sport/Recreation subscale.
The secondary outcomes were the other HAGOS subscales, iHOT-12, HSAS, pain during rest and activity (NRS), and EQ-5D
Both cohorts had significantly improved scores 1 year after surgery, with no difference between the 2 groups, except for the HSAS
Conclusion: No effect on clinical outcomes (HAGOS, iHOT-12, EQ-5D, and NRS) 1 year after hip arthroscopy for FAIS of closure of the interportal capsulotomy at termination of surgery.
