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.

Review Meta Analysis
Outcomes of arthroscopic anterior shoulder instability in the beach chair versus lateral decubitus position: a systematic review and meta-regression analysis.
This study aimed to systematically review the clinical outcomes and recurrence rates after arthroscopic anterior shoulder stabilization in the beach chair (BC) and lateral decubitus (LD) positions. ⋯ Level IV, systematic review of studies with Level I through Level IV evidence.

Randomized Controlled Trial
Efficacy of periarticular multimodal drug injection after medial opening-wedge high tibial osteotomy: a randomized, controlled study.
The purpose of this study was to evaluate the efficacy of periarticular multimodal drug injection after medial opening-wedge high tibial osteotomy regarding the postoperative pain level. ⋯ Level I, high-quality randomized controlled trial with statistically significant differences.
