Return to Sport Rates and Subjective Outcomes Are Similar After Open or Endoscopically Assisted Compartment Release for Chronic Lower-Extremity Exertional Compartment Syndrome.

Purpose: To retrospectively compare return to sport rates and subjective outcomes of patients who underwent open or endoscopic compartment release for the surgical management of chronic exertional compartment syndrome.

Methods: This was a retrospective review of patients who underwent lower-extremity fasciotomy for chronic exertional compartment syndrome from June 2012 to June 2020. Eligibility included patients 15 to 45 years of age who identified as an athlete and had at least 6 months of follow-up.

Articular Cartilage Damage Worsens from First-time to Recurrent Patellar Dislocation-A Longitudinal Magnetic Resonance Imaging Study.

Purpose: To compare the frequency and severity of articular cartilage injury on longitudinal magnetic resonance imaging (MRI) in patients after their initial dislocation and subsequent recurrent dislocations for those undergoing patellar stabilization surgery.

Methods: Between January 2012 and December 2017, patients undergoing patellar stabilization surgery were retrospectively reviewed. Only patients with an MRI after both the initial dislocation and subsequent dislocation events were included.

Anterior Cruciate Ligament Ruptures in the Skeletally Immature Current State of the Art.

Anterior cruciate ligament (ACL) injuries in children and adolescents are increasing every year. This patient population has unique risk factors and treatment considerations depending on specific patient factors and the level of bone maturity. This review summarizes the current data regarding pertinent features of the history and physical exam, indications for nonoperative management, assessment of skeletal maturity, and the surgical management of patients based on their unique physeal considerations.

Preoperative Bariatric Surgery Utilization Is Associated With Increased 90-day Postoperative Complication Rates After Total Joint Arthroplasty.

Background: This study evaluates the incidence of bariatric surgery (BS) before total joint arthroplasty (TJA) in New York State and compares patient comorbidities and 90-day postoperative complications of patients with and without BS before TJA.

Methods: The NY Statewide Planning and Research Cooperative System database between 2005 and 2014 was reviewed and 343,710 patients with TJA were identified. Patients were stratified into the following three cohorts: group 1 (patients who underwent BS < 2 years before TJA [N = 1,478]); group 2 (obese patients without preoperative BS [N = 60,259]); and group 3 (nonobese patients without preoperative BS [N = 281,973]).

Failure of Adjustably Aligned Modular Radial Head Arthroplasty With Head-Neck Dissociation and Metallosis.

Radial head arthroplasty was introduced in 1941 and the literature supports satisfactory overall midterm patient outcomes and acceptable complication profiles with several models. There are several previously described mechanisms by which radial head complications typically occur. We present the case of a rarely described mechanism of radial head implant failure: elbow synovitis and pain from partial dissociation and metallosis in an adjustably aligned, modular, monopolar, mixed metal, press-fit radial head arthroplasty.

Cytotoxicity evaluation of chlorhexidine gluconate on human fibroblasts, myoblasts, and osteoblasts.

Chlorhexidine gluconate (CHX) is widely used as a preoperative surgical skin-preparation solution and intra-wound irrigation agent, with excellent efficacy against wide variety of bacteria. The cytotoxic effect of CHX on local proliferating cells following orthopaedic procedures is largely undescribed. Our aim was to investigate the effects of CHX on primary fibroblasts, myoblasts, and osteoblasts.

Topical vancomycin and its effect on survival and migration of osteoblasts, fibroblasts, and myoblasts: An study.

The purpose of this study was to examine the influence of topical vancomycin on cell migration and survival of tissue healing cells. Human osteoblasts, myoblasts and fibroblasts were exposed to vancomycin at concentrations of 1, 3, 6, or 12 mg/cm for either a 1-h or 48-h (continuous) duration. Continuous exposure to all vancomycin concentrations significantly reduced cell survival (<22% cells survived) and migration in osteoblasts and myoblasts (P < 0.

Preoperative Bariatric Surgery and the Risk of Readmission Following Total Joint Replacement.

The purpose of this study was to compare nonelective and all-cause readmission rates and to identify risk factors for readmission of total joint arthroplasty (TJA) patients who had preoperative bariatric surgery (BS) compared with TJA patients without preoperative BS. The New York Statewide Planning and Research Cooperative System database was queried to identify 343,710 TJA patients between 2005 and 2014. Three patient groups were evaluated: group 1 (patients with preoperative BS within 2 years of TJA [N=1478]); group 2 (obese patients without preoperative BS [N=60,259]); and group 3 (nonobese patients without preoperative BS [N=281,973]).

Povidone-iodine Solutions Inhibit Cell Migration and Survival of Osteoblasts, Fibroblasts, and Myoblasts.

Study Design: In vitro laboratory study.

Objective: The purpose of this study was to identify the effect of dilute povidone-iodine (PVI) solutions on human osteoblast, fibroblast and myoblast cells in vitro.

Summary Of Background Data: Dilute PVI wound lavage has been used successfully in spine and joint arthroplasty procedures to prevent postoperative surgical site infection, but their biologic effect on host cells is largely unknown.

The Regionalization of Total Ankle Arthroplasties and Ankle Fusions in New York State: A 10-Year Comparative Analysis.

Background: Total ankle arthroplasty (TAA) provides an alternative to ankle fusion (AF). The purpose of this study is to (1) determine the extent of TAA regionalization, as well as examine the growth of TAA performed at high-, medium-, and low-volume New York State institutions and (2) compare this regionalization and growth with AF.

Methods: The New York Statewide Planning and Research Cooperative System (SPARCS) administrative data were used to identify 737 primary TAA and 7453 AF from 2005 to 2014.

Intensive ketamine use for multiple years: A case report.

Ketamine is known within the medical field for its anesthetic properties, yet its unique psychedelic and antidepressant properties are being increasingly recognized. We document the case of a patient with bipolar I disorder and an extensive history of substance dependence who used large doses of ketamine (1-3 g) on a daily basis over a period of 5 years, and described acute antidepressant effects as well as diminished cravings for alcohol. While his use was untenable and ultimately led to an inpatient admission, it is notable that he did not experience a withdrawal syndrome nor did he have any observable cognitive deficits upon cessation of use.
