What did the study look at?
Femoroacetabular impingement (FAI) is a condition in which an abnormal bone shape at the head-neck junction of the thigh bone or at the hip socket (acetabulum) causes the two to contact too early. Hip arthroscopy (keyhole surgery of the hip) is used to treat it surgically. The authors note that the procedure is technically demanding with a steep learning curve, and that the most common reason for revision is inadequate removal of the bump on the thigh bone (cam lesion). The aim of the article is to present the senior author's top 10 pearls for successful hip arthroscopy.
How was it done?
This is not a patient study but a video-supported surgical technique note. The authors list the steps in order:
- Positioning: slight head-down tilt, leg brought inwards and foot turned inwards; preferably a pink pad instead of a perineal post.
- Accurate portals: a three-portal technique, taking care not to stray too far towards the midline.
- Minimal capsular incision: keeping the cut in the joint capsule to 2 cm or less.
- Traction stitches: to create working space between the capsule and the labrum.
- Trimming the socket rim: only where the labrum is damaged.
- Balanced labral repair and anchor placement that spares the cartilage.
- Reshaping the thigh bone neck (osteochondroplasty), with intra-operative software (HipCheck) measuring the alpha angle in six positions to check the resection.
- Watertight closure of the capsule.
What did it find?
The article offers practical recommendations and pitfalls rather than measured outcomes. According to the authors, an overly large capsular incision can lead to long-term microinstability and scarring; rim trimming in patients with a shallow (dysplastic) socket can reduce bony coverage; over-resection of the cam lesion may predispose to femoral neck fracture, while under-resection may lead to revision surgery. Incomplete capsular closure is also linked with microinstability and worse outcomes.
The authors add that post-free traction, capsular management, labral treatment and the amount of bone resection remain debated in the literature.
The authors' conclusion
The authors state that this 10-step checklist may be used to minimise complications and optimise outcomes, and that it offers a framework especially for surgeons learning the procedure. Their recommendation is to divide the operation into these steps and master each before moving on to the next.
