Although continuous interscalene brachial plexus block (CISBPB) is common method in pain management following arthroscopic rotator cuff repair (ARCR), little is known about the analgesic effects of periarticular multimodal drug injection (PMDI) for ARCR. This retrospective study sought to clarify which technique could provide the best analgesic effect after ARCR. ⋯ Level III.

Comparative Study
Clinical and radiological outcomes between biportal endoscopic decompression and microscopic decompression in lumbar spinal stenosis.
Numerous minimal invasive techniques treating lumbar spinal stenosis have been introduced. Clinical results using biportal endoscopic spinal surgery has recently been introduced as a treatment option for lumbar spinal stenosis. The purpose of this study was to compare the clinical and radiologic outcome between microscopic unilateral laminotomy bilateral decompression and biportal endoscopic unilateral laminotomy bilateral decompression in patients with degenerative lumbar spinal stenosis. ⋯ Two different decompression techniques preserve the spinal structure and exhibit a favorable clinical outcome and have the advantage of not causing postoperative instability in the short term follow up. Biportal endoscopic surgery may leads to less postoperative back pain than microscopic surgery, which may allow early ambulation and shorter hospitalization period.
