Shoulder arthroscopy: a bridge from the past to the future

A Safe Technique to Ensure Not to Unload a Suture Anchor: Suture Dyeing

Suture anchors are frequently used in shoulder arthroscopy. After suture anchors are inserted into bone, the suture transfer between portals should be performed carefully. Sometimes, as a result of the transfer of the wrong suture limb, the suture anchor may be unloaded. The suture dyeing technique provides secure suture retrieval between portals.

Analgesic comparison between perineural and intravenous dexamethasone for shoulder arthroscopy: a meta-analysis of randomized controlled trials

Introduction

The analgesic comparison between perineural and intravenous dexamethasone on interscalene block for pain management after shoulder arthroscopy remains controversial. We conduct this meta-analysis to explore the influence of perineural versus intravenous dexamethasone on interscalene block for pain control after shoulder arthroscopy.

Methods

We have searched PubMed, Embase, Web of science, EBSCO and Cochrane library databases through April 2021 and included randomized controlled trials (RCTs) assessing the effect of perineural and intravenous dexamethasone on interscalene block in patients with shoulder arthroscopy.

Results

Five RCTs were included in the meta-analysis. Overall, compared with intravenous dexamethasone for shoulder arthroscopy, perineural dexamethasone led to similar block duration (SMD = 0.12; 95% CI − 0.12 to 0.35; P = 0.33), pain scores at 12 h (SMD = − 0.67; 95% CI − 1.48 to 0.15; P = 0.11), pain scores at 24 h (SMD = − 0.33; 95% CI − 0.79 to 0.14; P = 0.17), opioid consumption (SMD = 0.01; 95% CI − 0.18 to 0.19; P = 0.95) and incidence of nausea/vomiting (OR = 0.74; 95% CI 0.38–1.44; P = 0.38).

Conclusions

Perineural and intravenous dexamethasone demonstrated comparable pain relief after shoulder arthroscopy.

Current concepts in the evolution of arthroscopic rotator cuff repair

Arthroscopic rotator cuff repair has become one of the most common and successful surgeries performed in orthopedics. It represents the culmination of advances in many diverse fields such as optics, fluid dynamics, mechanical engineering, and most recently, orthobiologics. This article reviews the current state of the art of arthroscopic rotator cuff repair, through the lens of its historical context and evolution to our present understanding. We review the limitations in the current approach, and glance toward the future of rotator cuff regeneration with emerging technologies.
