Purpose: The aim of this study was to compare radiological changes in patellar height (PH) and patellar tendon length (PTL) after closure and non-closure of the patellar donor site defect during anterior cruciate ligament reconstruction (ACLR) using a bone-patellar tendon-bone (BPTB) autograft.

Methods: In this retrospective study a total of 63 patients was included. All patients underwent an arthroscopically assisted ACLR using the mid-third BPTB autograft.

Defining Clinically Meaningful Thresholds for 12-Month Patient-Reported Outcomes in Total Hip Arthroplasty; Toward Improving Threshold Accuracy.

Background: Clinically meaningful thresholds for patient-reported outcomes are relevant to define and predict success of total hip arthroplasties (THAs). Defining and offering thresholds must consider preoperative symptom severity.

Methods: In this retrospective study of 40,213 primary total hip replacements registered in the Dutch Arthroplasty Register (2016-2018), receiver operating curve analysis was used to define minimal clinically important changes and patient-acceptable symptom states with the anchor transition in function.

Estimating energy requirements from Dietary Reference Intakes for pregnant people with obesity using wearables.

Objective: Estimating physical activity levels (PAL) is difficult outside of the laboratory, and patient-reported PAL are often overestimated. Herein, we determine the importance of selecting the correct PAL when computing estimated energy requirements (EER) to determine gestational weight gain (GWG). Then, we examine whether data from a wearable can be used to select PAL and predict EER.

Return to work after proximal humeral fractures: a single center study comparing conservative versus operative treatment.

Background: Adequate treatment of proximal humeral fractures (PHF) is essential for restoring shoulder function and expediting return-to-work (RTW). This study aims to assess the impact of conservative and operative treatments on RTW and PHF recovery.

Objective & Methods: In a retrospective case-control study, 858 patients (aged 18-68) treated for PHF between 2018 and 2021 were included.

Image-based robotic (ROSA knee system) total knee arthroplasty with inverse kinematic alignment compared to conventional total knee arthroplasty : Study protocol and the inverse kinematic alignment in 8-steps using the ROSA Knee system for knee balancing technique explained.

Introduction: In 2020, 368 million people globally were affected by knee osteoarthritis, and prevalence is projected to increase with 74% by 2050. Relatively high rates of dissatisfactory results after total knee arthroplasty (TKA), as reported by approximately 20% of patients, may be caused by sub-optimal knee alignment and balancing. While mechanical alignment has traditionally been the goal, patient-specific alignment strategies are gaining interest.

Zuyderland Hip Inference for Survival and Lifetime Expectancy (ZHISLE) following hip fracture surgery: validation of the model that demonstrated good predictive power.

Purpose: Proximal femoral fractures are common within the elderly population and are associated with a high risk of mortality and reduced quality of life. Hemiarthroplasty or osteosynthesis (extramedullary or intramedullary) is the primary treatment option for these fractures. However, within this fragile patient population many comorbidities, among others dementia, are seen.

Effectiveness of intra-articular analgesia in reducing postoperative pain after minimally invasive sacroiliac joint fusion: a double-blind randomized controlled trial.

During the first postoperative days following minimally invasive sacroiliac joint fusion (MISJF), patients often report serious pain, which contributes to high utilization of painkillers and prevention of early mobilization. This prospective, double-blind randomized controlled trial investigates the effectiveness of intraoperative SIJ infiltration with bupivacaine 0.50% versus placebo (NaCl 0.

Accelerometer-based daily physical activity monitoring in patients with postpartum sacroiliac joint dysfunction: a case-control study.

Patients with low back pain caused by sacroiliac joint (SIJ) dysfunction have an impaired quality of life, due to reported pain, disability and activity limitations. There is increasing evidence that minimally invasive sacroiliac joint fusion (MISJF) results in improvement in pain, disability and quality of life in these patients. Some studies have reported improvements in daily physical activity following MISJF but based on bias-prone self-reports.

Examination of sex-specific interactions between gut microbiota and host metabolism after 12-week combined polyphenol supplementation in individuals with overweight or obesity.

Polyphenols exert beneficial effects on host metabolism, which may be mediated by the gut microbiota. We investigated sex-specific differences in microbiota composition and interactions with cardiometabolic parameters after polyphenol supplementation in individuals with overweight/obesity. In a double-blind, randomized, placebo-controlled trial, 19 women and 18 men with normal glucose tolerance and body mass index >25 kg/m received epigallocatechin-3-gallate and resveratrol (EGCG+RES, 282 + 80 mg/d) or placebo supplements for 12 weeks.

Transforaminal versus posterior lumbar interbody fusion for symptomatic single-level spondylolisthesis (LIFT): a multicentre controlled, patient blinded, randomised non-inferiority trial.

Background: The effectiveness of transforaminal lumbar interbody fusion (TLIF) compared to posterior lumbar interbody fusion (PLIF) in patients with single-level spondylolisthesis has not been substantiated. To address the evidence gap, a well-powered randomized controlled non-inferiority trial comparing the effectiveness of TLIF with PLIF, entitled the Lumbar Interbody Fusion Trial (LIFT), was conducted.

Methods: In a multicenter randomized controlled non-inferiority trial among five Dutch hospitals, 161 patients were randomly allocated to either TLIF or PLIF (1:1), stratified according to study site.

Permissive Weight Bearing in Proximal Humeral Fracture Management: A Survey-Based Inquiry in the Netherlands.

Purpose Proximal humeral fractures (PHF) are common, particularly among the elderly due to low-energy trauma. Adequate rehabilitation is essential for functional recovery, whether through conservative or surgical treatment. Permissive weight bearing (PWB) is a relatively new rehabilitation concept, characterized by earlier mobilization of the affected limb/joint after trauma.

Socioeconomic Status Affects Patient-Reported Outcome Measures in Total Hip and Knee Arthroplasty: A Retrospective Dutch Registry Study.

Background: To determine the association between socioeconomic status (SES) and patient-reported outcome measures in a Dutch cohort who have undergone total hip arthroplasty (THA) or total knee arthroplasty (TKA).

Methods: A retrospective national registry study of all patients who underwent primary THA or TKA between 2014 and 2020 in the Netherlands was performed. Linear mixed effects regression models were used to assess the association between SES and patient-reported outcome measures for THA and TKA patients separately.

Fetuin B in white adipose tissue induces inflammation and is associated with peripheral insulin resistance in mice and humans.

This study aimed to elucidate the mechanisms of action of fetuin B by investigating its putative effects on white adipose tissue metabolism.

Methods: First, fetuin B gene and protein expression was measured in multiple organs in mice and in cultured adipocytes.

Postoperative Load Bearing in Periprosthetic Femoral Fractures Around Hip Arthroplasty: A Survey Among Orthopedic Surgeons in the Netherlands.

Introduction: Permissive weight bearing (PWB) has relatively recently been implemented to optimize rapid clinical recovery and restoration of function in patients suffering lower extremity fractures. PWB shows outcome advantages in this patient category. Currently, there are no decisive recommendations on postoperative load-bearing management after surgically treated periprosthetic femoral fractures (PPFF) around hip arthroplasty.

No strong evidence of the protein leverage hypothesis in pregnant women with obesity and their infants.

Objective: The goal of this study was to investigate the role of dietary protein on macronutrient and energy intake, maternal adiposity during pregnancy, and infant adiposity at birth.

Methods: In 41 women with obesity, early-pregnancy (13-16 weeks) protein intake was assessed with food photography and expressed as a ratio of Estimated Average Requirements (EAR) in pregnancy for protein (0.88 g/kg/d), herein "protein balance.

Cost-effectiveness of patient specific conventional instrumentation for total knee arthroplasty: A systematic review and meta-analysis.

Background: Over the past years, patient specific instrumentation (PSI) for total knee arthroplasty (TKA) has been implemented and routinely used. No clear answer has been given on its associated cost and cost-effectiveness when compared to conventional instrumentation (CI) for TKA.

Aim: To compare the cost and cost-effectiveness of PSI TKA compared to CI TKA.

Involving Health Professionals in the Development of Quality and Safety Dashboards: Qualitative Study.

Background: Dashboards are an important tool for hospitals to improve quality and safety performance. However, implementing quality and safety dashboards often does not increase performance due to a lack of use by health professionals. Including health professionals in the development process of quality and safety dashboards can improve their use in practice.

Referrals, Symptoms and Treatment of Patients Referred to a Secondary Spine Centre-How Can We Help?

Introduction: Spinal disorders are amongst the conditions with the highest burden of disease. To limit the increase of healthcare-related costs in the ageing population, the selection of different types of care for patients with spinal disorders should be optimized. The first step is to investigate the characteristics of these patients and the relationship with treatment.

The relation between socioeconomic status and patient symptoms before and one year after lower extremity arthroplasty.

Aims: To determine whether there was a relation between socioeconomic status (SES) and patient symptoms before and one year after total knee arthroplasty (TKA), and/or total hip arthroplasty (THA) and whether a change in symptoms was clinically relevant.

Patients And Methods: A secondary analysis of a prospective cohort study was conducted on SES and osteoarthritis symptoms of patients (≥45 years old) who received a primary TKA or THA between 2016 and 2018. The relation between SES and respectively pre- and postoperative and change in patient-reported outcome measures including the Oxford Knee Score (OKS), Oxford Hip Score (OHS), Western Ontario and McMaster Universities Arthritis Index (WOMAC), the visual analog scale (VAS) for pain and the EuroQol 5-Dimensions (EQ-5D) were assessed using linear mixed-effects regression models adjusted for age and sex.

Demographics are no clinically relevant predictors of patient-reported knee osteoarthritis symptoms - Comprehensive multivariate analysis.

Aims & Objectives: In clinical practice, arthroplasties are predominantly indicated by clinical and radiological assessment of osteoarthritis. Pain and function are individually considered, but a comprehensive analysis of differences in symptom reporting by pre-operative factors is lacking. In the present study, we determined differences in patient reported outcome measures between demographic groups among patients admitted to total knee arthroplasty.

Motion analysis in patients with postpartum sacroiliac joint dysfunction: A cross-sectional case-control study.

Background: Patients with sacroiliac joint dysfunction are limited in daily life activities such as gait, climbing stairs and rising from a chair. It is well known that individuals with chronic low back pain have impaired balance compared to healthy individuals. This cross-sectional case-control study aims to investigate spatiotemporal parameters, center of pressure and mass, pelvic angles and other joint angles in patients with sacroiliac joint dysfunction in comparison with healthy controls.

A New Approach to Improve the Validity of Doubly Labeled Water to Assess CO2 Production during High-Energy Turnover.

Purpose: Accurate measurement of energy expenditure (EE) using doubly labeled water depends on the estimate of total body water (TBW).
