Translation and Validation of the Korean Version of the Postoperative Quality of Recovery Score QoR-15.

Quality of recovery after anesthesia is an important measure of the early postoperative health status of patients. The Quality of Recovery-15 (QoR-15) questionnaire is a self-rated questionnaire used to assess the quality of postoperative recovery. This study is aimed at translating and validating the Korean version of QoR-15 (QoR-15K).

Periimplant osteolysis does not affect the outcome of rotator cuff repair: a systematic review and meta-analysis.

Purpose: The goal of this study was to perform a systematic review and meta-analysis to compare the clinical and radiologic outcomes of rotator cuff repair, depending on the presence of developed periimplant osteolysis (PIO) after using suture anchors.

Methods: The electronic databases of MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for articles published up until October 2019 to find relevant articles comparing the outcomes of rotator cuff repair between the periimplant osteolysis group and non-periimplant osteolysis group. Data searching, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines.

Data search, extraction, analysis, and quality assessment were performed according to the Cochrane Collaboration guidelines, and the clinical outcomes were evaluated using various outcome values in young patients according to suture techniques.

Acute lumbosacral hemorrhagic ganglion cyst after transforaminal epidural steroid injection.

Epidural steroid injection is one of the most commonly used non-surgical treatments for degenerative lumbar vertebral disease. Its use has increased as degenerative lumbar vertebral disease has increased in frequency. Concomitant complications are being reported more often.

Arthroscopic meniscal surgery versus conservative management in patients aged 40 years and older: a meta-analysis.

Introduction: The efficacy of arthroscopic meniscus surgery in old aged patients remains controversial. The purpose of the present study was to review published studies comparing arthroscopic meniscal surgery with conservative management to treat meniscal injuries in patients 40 years of age and older.

Materials And Methods: Several electronic databases were queried for articles published until July 2017 that evaluated outcomes of arthroscopic meniscal surgery in patients aged 40 years and older.

Aortic arch repair under moderate hypothermic circulatory arrest with or without antegrade cerebral perfusion based on the extent of repair.

Background: For aortic-arch repair, moderate hypothermic circulatory arrest (HCA) have shown favorable outcomes over conventional deep HCA when coupled with antegrade cerebral perfusion (ACP); however, recent studies have shown that ACP may not be essential when circulatory arrest time is less than 30 minutes. This study aims to evaluate the stratified arch repair strategy of moderate HCA with or without ACP based on the extent of procedure.

Methods: Consecutive 138 patients (63 female; mean age, 60.

Risk Factors for Posterior Cage Migration after Lumbar Interbody Fusion Surgery.

Study Design: A retrospective clinical case series.

Purpose: To determine the strength of association between cage retropulsion and its related factors.

Overview Of Literature: Lumbar interbody fusion with cage can obtain a firm union and can restore the disc height with normal sagittal and coronal alignment.

Posterior Cruciate Ligament Reconstruction With Transtibial or Tibial Inlay Techniques: A Meta-analysis of Biomechanical and Clinical Outcomes.

Background: Transtibial (TT) or tibial inlay (TI) techniques are commonly used for posterior cruciate ligament reconstruction (PCLR). However, the optimum method for PCLR after PCL injury remains debatable. Hypothesis/Purpose: The hypothesis was that TT and TI techniques would not show significant differences for all outcome measures.

Single-Bundle versus Double-Bundle Posterior Cruciate Ligament Reconstruction: A Meta-Analysis of Randomized Controlled Trials.

Purpose: This meta-analysis evaluated the benefits of single-bundle (SB) and double-bundle (DB) surgical techniques for posterior cruciate ligament reconstruction (PCLR) in terms of clinical outcomes.

Methods: Five electronic databases were searched for relevant articles published until September 2016. Clinical outcomes of both techniques were evaluated using Lysholm knee function scores, Tegner activity scores, side-to-side differences, and International Knee Documentation Committee (IKDC) objective grades.

Biomechanical Comparison of Single-Bundle and Double-Bundle Posterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-Analysis.

Background: Of the many issues regarding surgical techniques for posterior cruciate ligament (PCL) reconstruction, the choice between single-bundle (SB) and double-bundle (DB) reconstruction is one of the most debated. However, it is unclear which of the reconstruction techniques yields better outcomes in knees with a PCL injury. The purpose of this meta-analysis was to compare the benefits of SB and DB PCL reconstruction in terms of biomechanical outcomes.

The role of isolated posterior cruciate ligament reconstruction in knees with combined posterior cruciate ligament and posterolateral complex injury.

Purpose: This is a meta-analysis comparing biomechanical outcomes to determine whether an isolated posterior cruciate ligament (PCL) reconstruction can restore normal knee kinematics in a combined PCL/posterolateral complex (PLC) injury and whether double-bundle (DB) PCL reconstruction is superior in controlling posterior and rotational laxity compared with single-bundle (SB) PCL reconstruction in a PCL/PLC-deficient knee.

Methods: A number of electronic databases were searched for relevant articles published through August 2016 that compared biomechanical outcomes of PCL reconstruction in patients who underwent reconstruction for combined PCL/PLC deficiencies. Data were searched, extracted, analysed, and assessed for quality according to Cochrane Collaboration guidelines, and biomechanical outcomes were evaluated using various outcome values.

Long-term intraocular pressure changes after intravitreal injection of bevacizumab.

Purpose: To assess the long-term intraocular pressure (IOP) changes after the intravitreal injection of bevacizumab (Avastin; Genentech, Inc., South San Francisco, CA) for treatment of age-related macular degeneration (AMD) and diabetic macular edema (DME) patients and evaluate the correlation factors.

Consideration of bone regeneration effect of stem cells: comparison of bone regeneration between bone marrow stem cells and adipose-derived stem cells.

Background: Much controversy exists as to how stem cells efficiently differentiate and regenerate. To research how stem cell origin affects optimal differentiation and regeneration, the authors collected stem cells from bone marrow and fat and compared amounts of bone regeneration from both groups of cells.

Methods: This study used 16 New Zealand white rabbits raised in similar surroundings and conditions.

Changes in the cutting efficiency of different types of dental diamond rotary instrument with repeated cuts and disinfection.

Statement Of Problem: Cutting efficiency is one of the most important factors to consider when a specific dental diamond rotary instrument is selected. However, the selection of a dental diamond rotary instrument is based on clinical experience rather than any scientific evidence.

Purpose: The purpose of this study was to identify how the cutting efficiency of different types of dental diamond rotary instrument changed with repeated cuts and disinfection.

Clinical trial of a pinpoint irradiation technique with the CO2 laser for the treatment of atrophic acne scars.

Ablative laser resurfacing is an effective treatment for atrophic acne scars. However, it often induces complications such as edema, prolonged erythema, scarring and hyperpigmentation. Therefore, a new concept of laser treatment called fractional photothermolysis has been designed to create microscopic thermal wounds to achieve skin rejuvenation treatment of atrophic acne scars.
