Summary
Arthroscopic treatment for femoroacetabular impingement (FAI) is safe and effective, showing improved patient scores and minimal complications. Pre-existing osteoarthritis may impact outcomes, but the procedure offers significant relief without perineal support.
Area of Science:
- Orthopedics
- Minimally Invasive Surgery
- Hip Arthroscopy
Background:
- Femoroacetabular impingement (FAI) is a condition requiring treatment, often addressed with minimally invasive arthroscopic surgery.
- Hip arthroscopy provides full access to the joint, enabling effective FAI treatment.
Purpose of the Study:
- To evaluate early experiences with hip arthroscopy for FAI using two distraction methods without perineal support.
- To assess the safety, morbidity, and early clinical/radiological outcomes of arthroscopic FAI release.
Main Methods:
- Retrospective study of 38 consecutive patients with FAI undergoing arthroscopic treatment.
- Two distraction techniques were used: invasive distractor (32 cases) and contralateral buttock support (6 cases).
- Clinical outcomes assessed using WOMAC and PMA scores; radiological outcomes by Tönnis osteoarthritis grading.
Main Results:
- No complications reported with either traction technique.
- Significant improvement in mean WOMAC scores (55 to 75) and PMA scores (14.6 to 16.7).
- 79% subjective patient satisfaction; minimal progression of osteoarthritis observed.
Conclusions:
- Arthroscopic FAI treatment is safe and effective, yielding positive early clinical results without perineal complications.
- The technique, particularly starting with peripheral compartment capsulotomy, allows effective distraction and FAI relief.
- Preoperative osteoarthritis is a negative prognostic factor for clinical outcomes in FAI treatment.
