Background: Patellar mobilization technique during total knee replacement (TKR) has been debated, with some suggesting that lateral retraction, rather than eversion, of the patella may be beneficial. This randomized controlled trial was to investigate the effects of patellar eversion on functional outcomes in TKR.
Methods And Analysis: This single-center, prospective, randomized controlled test will be conducted in Jingjiang People's Hospital. Primary end-stage osteoarthritis patients that prepared for unilateral TKR were randomized to one of two patellar exposure techniques during the primary total knee arthroplasty: lateral retraction or eversion. The informed consent will be acquired in each patient. The primary outcome was operation time, length of hospital stay, and straight leg raising time. Second outcomes including Insall-Salvati ratio; range of motion at 1 month, 3 months, and 1 year following TKR; visual analog scale (VAS) at 1 month, 3 months; and Knee Society Score (KSS) score at 1 year following TKR. The significance level was defaulted as P < .05.
Results: Results will be published in relevant peer-reviewed journals.
Conclusion: Our study aims to systematically assess the functional outcomes of patellar eversion for TKR patients, which will provide clinical guidance for TKR patients.

Proposal: Bold New Indications for Transcatheter Pulmonary Flow Restrictors.
Pediatr Cardiol
January 2025
Pediatric Heart Center, Johann-Wolfgang-Goethe University Clinic, Theodor-Storm-Kai 7, 60596, Frankfurt, Germany.
This proposal presents a proof of concept for the use of pulmonary flow restrictors (PFRs) based on MVP™-devices, drawing from clinical experience, and explores their potential role in the management of newborns with hypoplastic left heart syndrome (HLHS), other complex left heart lesions, and infants with end-stage dilated cardiomyopathy (DCM). At this early stage of age, manually adjusted PFRs can be tailored to patient's size and hemodynamic needs. Although currently used off-label, PFRs have substantial potential to improve outcomes in these vulnerable patient populations.

The amount of CD34 cells has been for decades the most important marker of autologous graft quality, but other graft cells, including various lymphocyte subsets, have gained some interest. This review attempts to summarize what is known about autograft cellular composition regarding post-transplant outcomes. The amount of CD34 cells in the graft is associated with tempo of platelet recovery.

Department of Anesthesiology, University of Wisconsin, Madison, WI, USA.
Objectives: Past studies have shown the efficacy of spinal targeted drug delivery (TDD) in pain relief, reduction in opioid use, and cost-effectiveness in long-term management of complex chronic pain. We conducted a survey to determine treatment variables associated with patient satisfaction.
Materials And Methods: Patients in a single pain clinic who were implanted with Medtronic pain pumps to relieve intractable pain were identified from our electronic health record.

Background: Studies are still limited on the isolated effect of retear after arthroscopic rotator cuff repair (ARCR) on functional outcomes after the midterm period.
Purpose: To assess the effect of retear at midterm follow-up after ARCR and to identify factors associated with the need for revision surgery.
Study Design: Cohort study; Level of evidence, 3.
Evaluation of Safety and Efficacy of a Single Lorecivivint Injection in Patients with Knee Osteoarthritis: A Multicenter, Observational Extension Trial.

Introduction: Lorecivivint (LOR), a CDC-like kinase/dual-specificity tyrosine kinase (CLK/DYRK) inhibitor thought to modulate inflammatory and Wnt pathways, is being developed as a potential intra-articular knee osteoarthritis (OA) treatment. The objective of this trial was to evaluate long-term safety of LOR within an observational extension of two phase 2 trials.
Methods: This 60-month, observational extension study (NCT02951026) of a 12-month phase 2a trial (NCT02536833) and 6-month phase 2b trial (NCT03122860) was administratively closed after 36 months as data inferences became limited.
