To examine the risks of shoulder arthroscopy in the beach-chair position (BCP) as opposed to the lateral decubitus position. The challenge during general anesthesia, particularly with the patient in the BCP, has been to ascertain the lower limit of blood pressure autoregulation, correctly measure mean arterial pressure, and adequately adjust parameters to maintain cerebral perfusion. There is increasing concern about the BCP and its association with intraoperative cerebral desaturation events (CDEs). Assessment of CDEs intraoperatively remains difficult; the emerging technology near-infrared spectroscopy (NIRS) may provide noninvasive, inexpensive, and continuous assessment of cerebral perfusion, offering an "early warning" system before irreversible cerebral ischemia occurs. ⋯ Level IV, systematic review of Level III and IV studies.

Comparative Study
Clinical and radiologic evaluation of arthroscopic medial meniscus root tear refixation: comparison of the modified Mason-Allen stitch and simple stitches.
This study compared the clinical and radiologic outcomes of arthroscopic medial meniscus root refixation using the modified Mason-Allen stitch and simple stitches. ⋯ Level III, retrospective comparative study.

Comparative Study
Injury to the suprascapular nerve during superior labrum anterior and posterior repair: is a rotator interval portal safer than an anterosuperior portal?
The purpose of this study was to compare the risk of injury to the suprascapular nerve during suture anchor placement in the glenoid when using an anterosuperior portal versus a rotator interval portal. ⋯ Using a rotator interval portal for suture anchor placement in the posterior aspect of the glenoid rim can lead to a higher likelihood of suprascapular nerve injury.

The purpose of this systematic review was to evaluate the literature to determine complications of hip arthroscopy, with a secondary focus on how to minimize complications and risks. ⋯ Level IV, systematic review of Level II to V studies.

The purpose of this investigation was to provide a detailed description of the anatomy of the hip capsule and pericapsular structures. ⋯ Knowledge of the intricate relation between the hip capsule and pericapsular structures presented here will be useful for surgeons as they perform the precise and specific capsular releases required during hip arthroscopy. Our anatomic findings contribute important qualitative data that build on the recent literature regarding the importance of capsular management during hip arthroscopy to postoperative hip stability.
