Femoroacetabular impingement (FAI) is a hip disorder which can often present bilaterally. The purpose of this systematic review was to explore the current practices for bilateral hip arthroscopy in treating FAI as they relate to outcomes and complications.
Overall, 19 studies were identified, comprising 957 patients (48.6% male) with a mean age of 27.9?±?7.1 years and a mean follow-up of 31.7?±?20.8 months.
--The majority of patients were treated with a staged bilateral hip arthroscopy with a mean duration between surgeries of 7.1?±?4.0 months.
--Significant preoperative-to-postoperative improvements for clinical outcomes such as pain, hip function, and health-related daily living as well as radiographic outcomes were reported in 6 studies for staged procedures and 3 studies for simultaneous procedures.
--Significant improvements in patient-reported outcomes were found in favor of those undergoing a shorter delay between surgeries in three studies (i.e.,?less than 3, 10 or 17 months) compared to those who had delayed surgeries.
Concluding, the bilateral FAI procedure produces improved postoperative results and unilateral surgery-like complication rates. The overall complication rate was 10.1% with revision surgery as the most prevalent complication. Bilateral operations are more prevalent than simultaneous operations.
