What did the study look at?
Hip arthroscopy is keyhole surgery in which the hip joint is entered through small incisions with a camera and specialised instruments. The authors note that it is technically demanding, requiring advanced three-dimensional spatial skills and specific instrumentation. Its most common indication is femoroacetabular impingement (FAI): abnormal contact between the head of the thighbone and the hip socket during movement. This publication is not a study presenting new patient data but a technique review sharing knowledge gained from previous operations (level of evidence V).
How was it done?
The authors divided the operation into stages and provided background from the literature and "pro tips" for each. The text is illustrated with operative images from the first author's archive and with demonstrations on cadaveric specimens.
What did it find?
- Patient positioning: The authors prefer the supine position. They report that traction-related complications can reach up to 74% of cases, most being temporary nerve symptoms that resolve on their own, and recommend keeping traction time under 2 hours to avoid nerve injury.
- Portals and access: Correct placement of the entry points, marked according to bony landmarks, is described as the first step that affects the whole flow of the operation; a joint distraction of 8–10 mm is usually adequate.
- Capsulotomy: Opening the joint capsule gives a wider view but damages the capsule, so the authors recommend keeping the interportal cut to 2 cm or less and repairing the capsule afterwards.
- Traction stitches: Suspending the capsule with sutures widens the view and working space and makes closure easier.
- Labral repair: The ring of cartilage around the socket (labrum) maintains the joint's suction seal and stability. The authors prefer to repair or reconstruct the labrum rather than trim or remove it, noting that this has been shown to be superior in the literature.
- Osteochondroplasty: When removing excess bone from the head of the thighbone (a CAM lesion), the aim is to restore its full spherical shape without thinning the head. Residual CAM deformity is reported as the most common cause of failure, and checking with multiple fluoroscopy views is recommended to avoid over- or under-resection.
- Capsule closure: According to the literature, closing the capsule restores native hip biomechanics more effectively and is associated with better functional outcomes. The authors close the capsule completely in all cases.
The authors' conclusion
The authors state that hip arthroscopy has a significant learning curve and demands considerable dedication, and that every stage, from setting up the traction table to closing the capsule, should follow standardised protocols. They regard capsular management, capsule closure and traction stitches as the current cornerstones of successful hip arthroscopy. These views are presented as expert opinion in a technique review.
