Perioperative Losartan Is Associated With Similar Rates of Additional Surgical Procedures for Postoperative Shoulder Stiffness After Primary Arthroscopic Rotator Cuff Repair but Lower Rates of Secondary Debridement and Repair.

Purpose: To compare the rate of additional shoulder surgery related to postoperative stiffness or tendon healing after primary rotator cuff repair between patients with a losartan prescription and without a losartan prescription.

Methods: The International Classification of Diseases, Tenth Revision, code M75.1 was used to identify all patients in the TriNetX Research Network with a rotator cuff tear diagnosis who underwent arthroscopic rotator cuff repair between January 1, 2015, and December 31, 2021.

Alarmingly High Rates of Deep Vein Thrombosis and Pulmonary Embolism Following Closed Reduction for Dislocated Total Hip Arthroplasty.

Background: Venous thromboembolism (VTE) and dislocation are well-described complications following total hip arthroplasty (THA). However, the relationship between THA dislocation and venous thromboembolism remains unclear. This study sought to determine the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients who experience a hip dislocation and subsequent closed reduction following primary THA.

The impact of preoperative benzodiazepine use on postoperative opioid use in total shoulder arthroplasty.

Background: As the rate of total shoulder arthroplasty (TSA) and preoperative benzodiazepine use rise, there is an increased need to understand the impact of preoperative benzodiazepine use on postoperative opioid consumption following TSA, especially amid the current opioid epidemic. The relationship between preoperative benzodiazepine use and chronic opioid use postoperatively has been well described following other orthopedic procedures; however, the impact on patients undergoing TSA remains unclear. This study aims to identify the impact of preoperative benzodiazepine use on opioid use following TSA.

Metacarpal Fracture Repair: Early Reoperation Rates and Characteristics.

Purpose: Metacarpal fractures are common injuries of the hand that often require operative repair. However, there is a paucity of data regarding the rate of reoperation and circumstances following metacarpal repair.

Methods: A retrospective review of all metacarpal fracture cases performed at a single academic institution between 2017 and 2021 was performed.

ChatGPT Provides Unsatisfactory Responses to Frequently Asked Questions Regarding Anterior Cruciate Ligament Reconstruction.

Purpose: To determine whether the free online artificial intelligence platform ChatGPT could accurately, adequately, and appropriately answer questions regarding anterior cruciate ligament (ACL) reconstruction surgery.

Methods: A list of 10 questions about ACL surgery was created based on a review of frequently asked questions that appeared on websites of various orthopaedic institutions. Each question was separately entered into ChatGPT (version 3.

High Levels of Satisfaction and Adequate Patient-Reported Outcomes After Operative Reconstruction of Multiligament Knee Injury With Allograft Among Patients Aged 40 Years and Older.

Purpose: To describe injury characteristics and patient-reported outcomes (PROs) among patients aged 40 years and older who underwent allograft reconstruction for multiligament knee injury (MLKI).

Methods: Records of patients aged 40 years and older who underwent allograft multiligament knee reconstruction at a single institution between 2007 and 2017 with a minimum of 2 years of follow-up were retrospectively reviewed. Demographic information, concomitant injuries, patient satisfaction, and PROs including International Knee Documentation Committee and Marx activity scores were obtained.

Incidence of Complications and Revision Surgery After High Tibial Osteotomy: A Systematic Review.

Background: High tibial osteotomy (HTO) is a well-recognized procedure for its effectiveness in treating symptomatic early knee arthritis and malalignment. Although there are numerous systematic reviews evaluating the management and outcomes after HTO, there are few investigations on complications of this procedure.

Purpose: To systematically review the literature to determine the incidence of intraoperative and postoperative complications associated with medial opening wedge and lateral closing wedge HTOs.

Intraosseous Regional Administration of Antibiotic Prophylaxis for Total Knee Arthroplasty: A Systematic Review.

Background: Intraosseous regional administration (IORA) of antibiotics after tourniquet inflation has recently been introduced as a technique to deliver antibiotics directly to the surgical site among patients undergoing total knee arthroplasty (TKA).

Methods: PubMed and Embase were queried for studies reporting on IORA for perioperative prophylaxis during TKA. Primary outcome measures were local tissue antibiotic concentrations and rates of prosthetic joint infection (PJI).

Revision Soft-Tissue Allograft Anterior Cruciate Ligament Reconstruction Is Associated With Lower Patient-Reported Outcomes Compared With Primary Anterior Cruciate Ligament Reconstruction in Patients Aged 40 and Older.

Purpose: To evaluate patient-reported outcomes (PROs) and graft failure rates in revision allograft anterior cruciate ligament reconstruction (ACLR) in patients aged 40 and older and compare them with primary ACLRs.

Methods: Patients aged 40 and older who underwent arthroscopic soft-tissue allograft ACLR between 2005 and 2016 with a minimum 2-year follow-up were retrospectively reviewed. Patients were grouped based on revision versus primary ACLR.

Fracture dislocations of the proximal humerus treated with open reduction and internal fixation: a systematic review.

Background: The treatment of proximal humerus fracture dislocations can be challenging given the extensive injury to the proximal humeral anatomy and increased risk of devascularization of the humeral head often seen in these injuries. The purpose of this study is to undertake a systematic review of the literature on the functional outcomes, rate of revision, and short- and long-term complications for proximal humerus fracture dislocations treated with open reduction and internal fixation (ORIF).

Methods: The PubMed and OVID Embase databases were queried for literature reporting on proximal humerus fracture dislocations treated with ORIF.

The Majority of Patients Aged 40 and Older Having Allograft Anterior Cruciate Ligament Reconstruction Achieve a Patient Acceptable Symptomatic State.

Purpose: To evaluate patient satisfaction, retear rates, and patient-reported outcomes (PROs) in patients aged 40 and older undergoing allograft anterior cruciate ligament reconstruction (ACLR). The secondary goal was to compare these parameters between groups of patients with intact versus failed grafts, and to evaluate these in relation to a historically reported International Knee Documentation Committee (IKDC) patient-acceptable symptoms state (PASS) score.

Methods: Records of patients aged 40 and older who underwent ACLR between 2005 and 2016 at a single institution with a minimum 2-year follow-up were retrospectively reviewed.

Imaging Active Surface Processes in Barnacle Adhesive Interfaces.

Surface plasmon resonance imaging (SPRI) and voltammetry were used simultaneously to monitor Amphibalanus (=Balanus) amphitrite barnacles reattached and grown on gold-coated glass slides in artificial seawater. Upon reattachment, SPRI revealed rapid surface adsorption of material with a higher refractive index than seawater at the barnacle/gold interface. Over longer time periods, SPRI also revealed secretory activity around the perimeter of the barnacle along the seawater/gold interface extending many millimeters beyond the barnacle and varying in shape and region with time.
