Keys to Arthroscopic Posterior Femoroplasty With Anteriorly Based Pre-bent Hip Burrs

Step	Procedure	Rationale
1	Central compartment hip arthroscopy Perform acetabuloplasty and labral repair, if indicated	•Diagnostic arthroscopy to determine whether acetabular pathology is present
2	Release traction device, flex hip to ∼40° Peripheral compartment entered and traction sutures applied (anteriorly and laterally) Anterolateral cam resection	•Improve visualization •Treat anterolateral cam lesion
3	Place hip in flexion and maximal external rotation (figure-of-4 position) 70° arthroscope through anterolateral portal with pre-bent burr in mid anterior portal	•Maximal rotation around femoral head to expose and visualize posterior cam lesion for resection •As resection occurs, more external rotation can be achieved •Remain proximal to the posterolateral retinacular vessels
4	Dynamic and fluoroscopic testing post-resection	•Determine if posterior cam lesion has been adequately decompressed
