Key Points for Arthroscopic Femoral Neck Osteoplasty

Remain cognizant of the position of the superior retinacular vessels throughout the case to prevent iatrogenic avascular necrosis of the femoral head.

Use a T-capsulotomy to increase visualization, especially if the cam lesion extends distally.

The majority of the resection is performed with the hip in a slightly flexed, abducted, and internally rotated position.

The medial extent of the cam lesion can be accessed by slight external rotation of the hip.

The lateral extent can be accessed by working through the anterolateral portal.

The proximal extent can be accessed by placing the hip in full extension.

Use fluoroscopy to guide the resection and to verify a complete resection.

Repair the descending limb of the T-capsulotomy to avoid iatrogenic instability of the hip.
