[PMID: 38036252 DOI: 10.1016/j.jse.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 09/17/2023] [Accepted: 10/18/2023] [Indexed: 12/02/2023]
Abstract
BACKGROUND Body mass index (BMI) is a modifiable risk factor for medical and infectious complications following total shoulder arthroplasty (TSA). Previous studies investigating BMI were limited to the conventional classification system, which may be outdated for modern day patients. Therefore, the purpose of this study was to identify BMI thresholds that are associated with varying risk of 90-day medical complications and 2-year prosthetic joint infection (PJI) following TSA. METHODS A national database was utilized to identify 10,901 patients who underwent primary elective TSA from 2013 to 2022. Patients were only included if they had a BMI value recorded within 1 month prior to TSA. Separate stratum-specific likelihood ratio analyses, an adaptive technique to identify data-driven thresholds, were performed to determine data-driven BMI strata associated with varying risk of 90-day medical complications and 2-year PJI. The incidence rates of these complications were recorded for each stratum. To control for confounders, each BMI strata was propensity-score matched based on age, sex, hypertension, heart failure, chronic obstructive pulmonary disease, and diabetes mellitus to the lowest identified BMI strata for both outcomes of interest. The risk ratio (RR) and 95% confidence interval (CI) were recorded for each matched analysis. RESULTS The average age and BMI of patients was 70.5 years (standard deviation ±9.8) and 30.7 (standard deviation ±6.2), respectively. Stratum-specific likelihood ratio analysis identified two BMI strata associated with differences in the rate of 2-year PJI: 19-39 and 40+. The same strata were identified for 90-day major complications. When compared to the matched BMI 19-39 cohort, the risk of 2-year PJI was higher in the BMI 40+ cohort (RR: 2.7; 95% CI 1.39-5.29; P = .020). After matching, there was no significant difference in the risk of 90-day major complications between identified strata (RR: 1.19, 95% CI: 0.86-1.64; P = .288). CONCLUSION A data-driven BMI threshold of 40 was associated with a significantly increased risk of 2-year PJI following TSA. This is the first TSA study to observe BMI on a continuum and observe at what point BMI is associated with increased risk of 2-year PJI following TSA. Our identified BMI strata can be incorporated into risk-stratifying models for predicting both PJI and 90-day major complications to minimize both.

Abstract
(1) Background: Osteoarthritis is a degenerative joint disease that is commonly diagnosed in the aging population. Interestingly, the lower extremity joints have a higher published incidence of osteoarthritis than the upper extremity joints. Although much is known about the disease process, it remains unclear why some joints are more affected than others. (2) Methods: A comprehensive literature review was conducted utilizing the search engines PubMed, Google Scholar, and Elsevier from 2014 to 2024, directing our search to osteoarthritis of various joints, with the focus being on glenohumeral osteoarthritis. (3) Results and Discussion: The literature review revealed a publication difference, which may be explained by the inconsistency in classification systems utilized in the diagnosis of shoulder osteoarthritis. For instance, there are six classification systems employed in the diagnosis of glenohumeral osteoarthritis, making the true incidence and, therefore, the prevalence unobtainable. Furthermore, susceptibility to osteoarthritis in various joints is complicated by factors such as joint anatomy, weight-bearing status, and prior injuries to the joint. (4) Conclusions: This review reveals the lack of understanding of shoulder osteoarthritis's true incidence and prevalence while considering the anatomy and biomechanics of the glenohumeral joint. In addition, this is the first paper to suggest a single criterion for the diagnosis of glenohumeral osteoarthritis.

Comparing Outcomes After Referral to Physical Therapy for Patients With Glenohumeral Osteoarthritis Based on the Radiographic Osteoarthritis Severity: A Retrospective Analysis. Cureus 2023; 15:e43027. [PMID: 37674967 PMCID: PMC10479957 DOI: 10.7759/cureus.43027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/06/2023] [Indexed: 09/08/2023] Open
Abstract
Introduction Glenohumeral osteoarthritis (GHOA) is a common cause of musculoskeletal pain (MSP) that can frequently lead to pain and functional disability in patients throughout the world. GHOA can be managed with conservative or surgical interventions, although conservative interventions, such as physical therapy (PT), are generally first-line interventions depending on the severity of GHOA. The purpose of this retrospective analysis was to examine how conventional PT impacts outcomes for patients with GHOA based on the severity of radiographic GHOA findings. Methods This study is a retrospective chart review of patients who were referred to PT for MSP and received PT in the outpatient setting between 2016 and 2022. Inclusion criteria were patients who received PT in the outpatient setting, received PT for MSP, had shoulder radiograph imaging within two years of initial PT evaluation, had more than one PT visit (i.e. attended a follow-up session after initial evaluation), and did not have a history of shoulder surgery. Primary outcome measures were pain, abduction active range-of-motion (AROM), and disability via the quick disabilities of the arm, shoulder, and hand (DASH). Patients were divided into the No GHOA group (n=104), Mild GHOA group (n=61), and Moderate/Severe GHOA group (n=55) based on the radiographic GHOA severity. Results All included patients (n=220) had a mean age of 62.2 ± 12.4 years old with a mean number of PT visits of 7.8 ± 4.5 visits. There was initially a significant difference in the magnitude of pain improvement between the three groups based on radiographic severity of GHOA (Kruskal-Wallis H=6.038; p=0.049); however, post hoc testing revealed no significant difference between any of the three groups for pain improvement (p=0.061 to p=1.000). There was also no significant difference in the magnitude of abduction AROM improvement between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=2.887; p=0.236). Finally, there was no significant difference in the magnitude of disability improvement via the Quick DASH between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=0.156; p=0.925). Conclusion Patients with GHOA referred to PT experience small but statistically significant short-term improvements in pain, abduction AROM, and disability regardless of GHOA radiographic severity. There is no significant association between the magnitude of clinical improvement and the severity of radiographic GHOA. However, despite statistically significant improvements in pain, only patients with mild GHOA experienced clinically significant improvements in pain. Patients with GHOA, regardless of severity, may or may not experience clinically significant improvements in disability after PT.

Abstract
BACKGROUND Image-guided intra-articular injections are commonly performed to reduce pain in patients with arthritis or other joint-related pathology. Utilizing a needle length that is too short could lead to increased patient discomfort, increased procedural time, and extra-articular injections. OBJECTIVE To predict the minimum needle length required for fluoroscopic-guided intra-articular injections of the hips, knees, and shoulders based on patient age, gender, height and weight, or BMI; and to evaluate whether this varies by gender. STUDY DESIGN Cross-sectional study. SETTING Tertiary care academic center. PARTICIPANTS 600 consecutive patients with available magnetic resonance imaging (MRI) of the hips, knees, and shoulders (100 males and 100 females for each joint). METHODS The distance from the skin to the joint (glenohumeral, hip and knee) and the thickness of the subcutaneous fat pad (distance from the skin to the muscle) along the injection path were measured. Multivariable linear ridge regression with 10-fold cross-validation was used to predict the distance from the skin to the hip, knee, and glenohumeral joints using age, gender, weight, and height; or using age, gender, and BMI. RESULTS The data show that the subcutaneous fat thickness and the distance from the skin to all joints increase with weight (P < 0.001) and BMI (P < 0.001). Subcutaneous fat pads around the anterior shoulder (P < 0.02) and knee (<0.001) are thicker in women than in men. CONCLUSIONS Patient habitus, in particular weight and BMI, are strong predictors of the thickness of the subcutaneous fat pads and consequently strong predictors of the distance from the skin to the joint. Subcutaneous fat pad thickness around the shoulders and knees varies by gender. We present nomograms showing the minimal needle length required to achieve intra-articular injections of the hip, knee and glenohumeral joints. This article is protected by copyright.

J Orthop Surg Res 2022; 17:97. [PMID: 35168639 PMCID: PMC8848821 DOI: 10.1186/s13018-022-02998-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 02/04/2022] [Indexed: 11/18/2022] Open
Abstract
Background Epidemiological studies have reported a positive association between hypercholesterolemia and shoulder disease. Previous studies have focused on the effect of hypercholesterolemia on tendinopathy. Moreover, hypercholesterolemia has also been linked to joint pathology in the knee and hand. However, the effect of hyperlipidemia on glenohumeral joint remain unclear. A hypercholesterolemic condition has been reported to alter levels of A Disintegrin and Metalloprotease with Thrombospondin Motifs (ADAMTSs) and matrix metalloproteases (MMPs) in synovium of the knee joint. Here, we evaluated the mRNA expression of ADAMTSs and MMPs in the glenohumeral synovium of patients with and without hypercholesterolemia. Methods Study participants were 73 patients who underwent arthroscopic rotator cuff repair for degenerative rotator cuff tears. They were divided into two groups according to total cholesterol (TC) and triglyceride levels. Synovial membrane samples were harvested at the rotator interval during surgery, and mRNA expression levels of the aggrecanases ADAM-TS4 and ADAM-TS5 and MMPs (MMP-1, 3, 9, and 13) were analyzed quantitatively. Results ADAM-TS5 and MMP1 mRNA levels were significantly higher in the high TC group than in the low TC group (P = 0.023 and P = 0.025, respectively). In contrast, no significant differences were observed in ADAMTS4 or MMPs 3, 9, and 13 (ADAMTS4, P = 0.547; MMP3, P = 0.55; MMP9, P = 0.521; and MMP13, P = 0.785). Conclusion Hypercholesterolemia may alter MMP1 and ADAMTS5 expression in the synovium of the glenohumeral joint.

Preventative and Disease-Modifying Investigations for Osteoarthritis Management Are Significantly Under-represented in the Clinical Trial Pipeline: A 2020 Review. Arthroscopy 2021; 37:2627-2639. [PMID: 33812028 DOI: 10.1016/j.arthro.2021.03.050] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 02/10/2021] [Accepted: 03/23/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To conduct a review of active United States-based clinical trials investigating preventative, symptom resolution, and disease-modifying therapies for osteoarthritis (OA). METHODS We conducted a review of currently active clinical trials for OA using data obtained from the ClinicalTrials.gov database as of August 2020. The inclusion criteria were active studies registered in the United States that involved the prevention, symptom resolution, or disease modification of OA. Descriptive statistics were recorded and summarized. RESULTS A total of 3,859 clinical trials were identified, and 310 were included in the final analysis. Of the currently active trials, 89% (n = 275) targeted symptom resolution in patients with existing OA, 6% (n = 19) targeted OA disease-modifying therapeutics, and 5% (n = 16) targeted the prevention of OA in high-risk patients (P < .001). Primary interventions included medical devices (44%, n = 137), pharmaceutical drugs (14%, n = 42), surgical procedures (14%, n = 42), cellular biologics (13%, n = 41), and behavioral therapies (13%, n = 41). There was a significantly higher number of disease-modifying therapeutics for cellular biologics than pharmaceutical drugs (30% vs 14%) (P = .015). Most trials targeted the knee joint (63%, P = .042), with 38% of all trials evaluating joint arthroplasty. There were no significant differences between private sector and government funding sources (43% and 49%, respectively) (P = .288), yet there was a significantly lower rate of funding from industry (8%) (P = .026). CONCLUSIONS There was a significantly higher number of clinical trials investigating symptomatic resolution therapy (89%) for existing OA in comparison to preventative (5%) and disease-modifying (6%) therapies. The most common interventions involved medical devices and joint replacement surgery, with the knee joint accounting for more than 60% of the current clinical trials for OA. There was a significantly higher number of disease-modifying therapeutics for cellular biologics than pharmaceutical drugs. Funding of clinical trials was split between the private sector and government, with a low rate of reported funding from industry partners. CLINICAL RELEVANCE Identifying existing needs in the current market may help increase rates of research funding or optimize current funding pathways, in this study, specifically for targeting unaddressed focus areas in OA research. Our systematic review highlights the potential need for additional research and development regarding OA preventative and disease-modifying therapies.
