Stress shielding in reverse shoulder arthroplasty using a proximally coated stem for proximal humeral fractures: Does it have clinical relevance?
Shoulder Elbow
January 2025
Orthopaedic and Trauma Surgery Department, Hospital de Terrassa, Terrassa, Barcelona, Spain.
Objectives: To evaluate the clinical significance of stress shielding in patients who have undergone an uncemented reverse shoulder arthroplasty (RSA) with a proximally coated stem for complex proximal humeral fractures (PHF) comprising 3 or 4 parts, assessed at 2 years postoperatively. Additionally, this study aims to examine the correlation between tuberosity healing and clinical outcomes.
Methods: Single Centre.
Evaluation and refinement of thresholds for early migration of total knee replacements as an estimator of late aseptic loosening: an updated systematic review of RSA and survival studies.
Acta Orthop
January 2025
Department of Orthopaedics, Leiden University Medical Center, Leiden, The Netherlands.
Background And Purpose: This study updates 2 parallel systematic reviews and meta-analyses from 2012, which established the 1-year radiostereometric (RSA) migration thresholds for tibial components of total knee replacements (TKR) based on the risk of late revision for aseptic loosening from survival studies. The primary aim of this study was to determine the (mis)categorization rate of the 2012 thresholds using the updated review as a validation dataset. Secondary aims were evaluation of 6-month migration, mean continuous (1- to 2-year) migration, and fixation-specific thresholds for tibial component migration.

Department of Epidemiology, School of Health, Mashhad University of Medical Science, Mashhad, Iran.
Background: In order to increase the stability of tibial component in total knee arthroplasty (TKA), intramedullary stem extensions (SE) have been developed. The aim of this systematic review and meta-analysis is to address the critical knowledge gap on post-operative outcomes and complications rate comparison between tibial component with SE compared to the tibial component standard configuration (SC) in primary cemented TKA.
Methods: We conducted a comprehensive search of online databases, including Pubmed, Embase, ISI Web of science, Cochrane Library, and Scopus, using the following MeSH terms, (total knee arthroplasty) OR (TKA) OR (total knee replacement) AND (Tibial stem) OR (stem extension) OR (long stem).
Haemodynamic measurements during hip hemiarthroplasty surgery for hip fracture.
Bone Joint J
January 2025
Oxford Trauma and Emergency Care, Nuffield Department of Orthopaedics, Rheumatology, and Musculoskeletal Sciences, Kadoorie Centre, University of Oxford, Oxford, UK.
Aims: There is compelling evidence for the use of cemented hip hemiarthroplasty for displaced intracapsular hip fractures; however, the risks of cement are well reported and in rare cases may be associated with haemodynamic collapse. It is therefore important to improve our understanding of haemodynamic instability, intraoperative monitoring, and strategies to reduce the risk to patients.
Methods: We measured arterial blood pressure using the LiDCO Continuous Non-invasive Arterial Pressure (CNAP) finger cuff during surgery in patients enrolled in the WHiTE 5 trial randomized to cemented or modern uncemented hip hemiarthroplasty at a single recruiting site.
Cementless fixation in total knee arthroplasty: current evidence and future perspective.
Arch Orthop Trauma Surg

Faculty of Medicine, Johannes Kepler University Linz, Altenberger Strasse 69, 4040, Linz, Austria.
Article Synopsis
- Cementless fixation is becoming more important in total knee arthroplasty (TKA), and this article reviews its functional outcomes and how long the implants last.
- A thorough literature search identified 15 studies published between 2010 and 2022, with 11 comparing cementless to cemented TKA and 4 focusing solely on cementless implants.
- The findings suggest that cementless TKA has functional outcomes and survivorship that are at least as good as cemented implants, and advancements in technology may lead to increased adoption of cementless methods in the future.
