Extended length of stay and postoperative complications in octogenarians with hypertension following revision total knee arthroplasty

The role of hypertensive status in the preoperative patient selection of TSA

Background

This study investigates the relationship between hypertension and postoperative complications following total shoulder arthroplasty (TSA).

Methods

All patients who underwent TSA between 2015 and 2020 from the American College of Surgeons National Surgical Quality Improvement database were surveyed. The study population was divided into patients with no hypertension and patients with hypertension. Patient demographics, comorbidities, and 30-day postoperative complications were collected. Logistic regression analysis was used to investigate the relationship between hypertension and postoperative complications.

Results

Compared to no hypertension, hypertension was significantly associated with an increased likelihood of experiencing sepsis (P = .021), pneumonia (P = .019), myocardial infarction (P = .038), blood transfusions (P = .006), readmission (P < .001), reoperation (P < .001), non-home discharge (P < .001), and any complication (P < .001). After accounting for significant patient variables, compared to no hypertension, hypertension was independently significantly associated with an increased likelihood of experiencing reoperation (odds ratio 1.48; 95% CI, 1.142-1.905; P = .003) and any complication (odds ratio 1.10; 95% CI, 1.008-1.205; P = .033).

Conclusion

In this study, we identified hypertension as an independent significant predictor for both reoperation and any complication following TSA. This study provides evidence for incorporating a patient's hypertensive status into preoperative screening, aiming to improve surgical candidate selection and surgical outcomes following TSA.

Hypertension and postoperative complications following arthroscopic rotator cuff repair

Background

The purpose of this study was to investigate the relationship between hypertension and postoperative complications following arthroscopic rotator cuff repair (aRCR).

Methods

The American College of Surgeons National Surgical Quality Improvement Program database was surveyed for all patients who underwent aRCR between 2015 and 2021. Patient demographics, comorbidities, and 30-day postoperative complication data were analyzed. Multivariate logistic regression identified postoperative complications associated with hypertension.

Results

Forty-six thousand five hundred and sixty-two patients were included in the analysis: 20,999 (45.1%) patients in the hypertensive cohort and 25,563 (54.9%) in the nonhypertensive cohort. Hypertension was associated with male gender (P < .001), age ≥ 65 years (P < .001), body mass index > 30 (P < .001), dependent functional status (P < .001), American Society of Anesthesiologists classification ≥ 3 (P < .001), current smoker (P < .001), diabetes (P < .001), chronic obstructive pulmonary disease (P < .001), and bleeding disorders (P < .001). Thrity-day postoperative complications significantly associated with hypertension included pneumonia (P = .012), reintubation (P = .009), urinary tract infection (P = .002), stroke (P = .044), myocardial infarction (P = .004), ventilator > 48 hours (P = .017), readmission (P < .001), non-home discharge (P < .001), and mortality (P = .020). After adjusting for patient demographics and comorbidities, readmission (odds ratio [OR] 1.41; 95% confidence interval [CI] 1.13-1.75; P = .002) was independently associated with hypertension.

Conclusion

Hypertension was identified as a risk factor for various postoperative complications following aRCR. Hypertension was found to be an independent predictor for readmission following aRCR.

IL-17 in osteoarthritis: A narrative review

Osteoarthritis (OA) is a painful joint disease that is common among the middle-aged and elderly populations, with an increasing prevalence. Therapeutic options for OA are limited, and the pathogenic mechanism of OA remains unclear. The roles of cytokines and signaling pathways in the development of OA is a current research hot spot. Interleukin (IL)-17 is a pleiotropic inflammatory cytokine produced mainly by T helper 17 cells that has established roles in host defense, tissue repair, lymphoid tissue metabolism, tumor progression, and pathological processes of immune diseases, and studies in recent years have identified an important role for IL-17 in the progression of OA. This narrative review focuses on the mechanisms by which IL-17 contributes to articular cartilage degeneration and synovial inflammation in OA and discusses how IL-17 and the IL-17 signaling pathway affect the pathological process of OA. Additionally, therapeutic targets that have been proposed in recent years based on IL-17 and its pathway in OA are summarized as well as recent advances in the study of IL-17 pathway inhibitors and the potential challenges of their use for OA treatment.

A Comparative Analysis of Perioperative Complications in Octogenarians and Patients under 60 Years of Age after Primary Cemented Total Knee Arthroplasty

Introduction: Knee arthroplasty is exposed to demographic changes as patients age. An analysis of risk factors for surgical treatment decisions in patients over 80 years old is crucial. This study compared perioperative complications between groups of patients undergoing primary knee arthroplasty, under 60 years old and over 80 years old.Materials and Methods: For this retrospective study, data from 400 patients with primary cemented bi- and unicondylar total knee endoprosthesis during inpatient stay from 2017 to 2018 were analyzed. Patients aged 61-79 years (257) were excluded. An analysis of the remaining 143 patients was performed. The incidence of surgery-related and systemic complications (eg, urinary tract infections, electrolyte imbalances, and cases of pneumonia), the blood supply and C-reactive protein (CRP) as well as hemoglobin progression were compared across both age groups. Furthermore, a correlation between prevalent diseases and systemic complications were investigated. Statistical analysis was performed using IBM SPSS (Armonk, US).Results: Data analyses showed a significant difference in the occurrence of systemic complications and blood transfusion between the age groups (P = 0.001, phi = 0.44; phi= 0.55, P = 0.001). Surgical complications did not differ significantly between the age groups. Age-typical pre-existing conditions, especially arterial hypertension (P = 0.003), showed a significant association with the occurrence of systemic complications. In addition, high postoperative CRP values in elderly patients revealed an association to systemic complications (P = 0.008).Discussion and Conclusion: The study shows that primary cemented knee arthroplasty is a safe procedure without an increased incidence of surgical complications, even in elderly patients. The increased incidence of internal complications in octogenarians, in turn, should receive more attention in the perioperative course. The interdisciplinary preoperative optimization of pre-existing conditions and drug therapy, as well as close interdisciplinary assessments of elderly patients, should be ensured.

Length of Hospital Stay after Total Knee Arthroplasty: A Correlation Study on 1200 Patients

In countries with a high average population age, total knee arthroplasty is still carried out in an inpatient setting. The roadmap to performing major surgery on an outpatient basis passes through the understanding of those perioperative features that correlate with higher lengths of hospital stay (LOS). A retrospective database of 1200 patients was reviewed for retrieving preoperative and perioperative factors including anthropometric and demographic data, comorbidities, preoperative laboratory assessment, and surgical time. Considering the LOS as a discrete series, data were analyzed by means of logistic regression with multiple univariate and multivariate models. The results showed a median length of hospital stay of 3 (IQR 3, 4) days. According to multiple univariate analysis, arterial hypertension (p = 0.008), diabetes mellitus (p = 0.028), CCI score (p < 0.001), ASA score (p = 0.006), surgical time (p < 0.001) and intraoperative blood loss (p < 0.001) were significantly associated with the duration of hospital stay in days. Moreover, preoperative hemoglobin value was inversely correlated to the LOS (p = 0.008). Multivariate analysis showed a significant correlation between LOS and surgical time and intraoperative blood loss. Many factors influence the permanence of the inpatient and acting on those variables, by stabilizing comorbidities and optimizing laboratory values, may reduce the overall healthcare burden.
