Pearls and Pitfalls of Arthroscopic Posterior Femoroplasty With Anteriorly Based Pre-bent Hip Burrs

Pearls	Pitfalls
Make a generous transverse capsulotomy, which can be closed at the end of the case	If on preoperative physical examination the patient cannot get at least 75° of external rotation in a FABER position, anticipate that this approach will be difficult, and probably require a larger capsulotomy.
Most traction devices allow some flexion and extension of the hip. Fine tune exposure by adjusting the hip flexion in the figure of four position	Avoid the temptation to do this as a radiographic only procedure. Since the femoral head is a 3-dimensional sphere, using 2-dimensional radiograph alone risks injury to femoral head articular cartilage.
If there is any disorientation, do not hesitate to use a single shot of fluoroscopy to help with orientation	If it is relatively easy to access the posterior aspect of the hip through this approach, be highly suspicious for capsular laxity. Even if you traditionally do not suture close or plicate the capsule, in this situation, strongly consider closing the capsule.
