The changing effect of surgeon volume on revision rates in shoulder arthroplasty with time in Australia.

Background: The concept that surgical volume effects rates of total primary shoulder arthroplasty (TSA) revision is widely accepted. The aim of this study was to determine if surgical volume is confounded by patient, implant, institutional factors and time from TSA.

Methods: Using data from a large national arthroplasty registry for the period 1 January 2008 to 31 December 2022, all interactions with orthopedic surgeon volume (SV) undertaking primary TSA procedures for all diagnoses were examined.

Comparative and predictive modelling of modern anatomic total shoulder arthroplasty revision rates in osteoarthritis with different polyethylene glenoid designs.

Background: The revision rates of four modern (currently used) polyethylene glenoid designs in anatomic total shoulder arthroplasty (stemmed and stemless) for osteoarthritis (OA) are compared from a national arthroplasty registry to model predictive variables.

Materials And Methods: The study period was 1 January 2008 to 31 December 2023. The study population included all primary anatomic total shoulder arthroplasty (aTSA) procedures undertaken for OA.

Access to shoulder arthroplasty in Australia: A balance of regulation, surveillance, and monitored efficacy to maximize patient outcome and optimum care.

Prosthetic arthroplasty has emerged as a major contributor to the management of shoulder disorders. This paper outlines the situation in Australia regarding the process by which shoulder replacement devices are made available. Although entry of joint replacement devices to the Australian market is relatively unrestricted, they must be first approved by the Therapeutic Goods Administration-based on safety and efficacy-to be legally used.

Stemless anatomic and reverse shoulder arthroplasty in patients under 55 years of age with primary glenohumeral osteoarthritis: an analysis of the Australian Orthopedic Association National Joint Replacement Registry at 5 years.

Background: Primary glenohumeral osteoarthritis in young patients poses challenging treatment decisions. Arthroplasty options have different failure profiles and implant survivorship patterns. This registry study aims to analyze the cumulative per cent revision (CPR) rate of different types of arthroplasties conducted for primary osteoarthritis in patients below 55 years of age.

Demographics, Indications, and Revision Rates for Radial Head Arthroplasty: Analysis of Data from the Australian Orthopaedic Association National Joint Replacement Registry.

Background: Population-level data from national arthroplasty registries enable the use and outcomes of arthroplasty procedures to be monitored over time. This study aimed to describe the demographics, indications, and outcomes (up to 15 years) for radial head arthroplasty (RHA) procedures in Australia, as well as the factors associated with an increased likelihood of revision.

Methods: Individual-level deidentified data on demographics and surgery characteristics, including revision surgery, were obtained from the Australian Orthopaedic Association National Joint Replacement Registry for all primary isolated RHA procedures that had been performed from 2007 to 2021.

Comparable low revision rates of stemmed and stemless total anatomic shoulder arthroplasties after exclusion of metal-backed glenoid components: a collaboration between the Australian and Danish national shoulder arthroplasty registries.

Background: The stemmed anatomic total shoulder arthroplasty is the gold standard in the treatment of glenohumeral osteoarthritis. However, the use of stemless total shoulder arthroplasties has increased in recent years. The number of revision procedures are relatively low, and therefore it has been recommended that national joint replacement registries should collaborate when comparing revision rates.

A comparison of revision rates for stemmed and stemless primary anatomic shoulder arthroplasty with all-polyethylene glenoid components: analysis from the Australian Orthopaedic Association National Joint Replacement Registry.

Background: We compared the rate of all-cause revision of 2 classes of primary anatomic shoulder arthroplasty, stemmed (stTSA) and stemless (slTSA), undertaken with cemented all-polyethylene glenoid components.

Methods: A large national arthroplasty registry identified 2 cohort groups for comparison, stTSA and l undertaken for all diagnoses between January 1, 2011, and December 31, 2021. A subanalysis from January 1, 2017, allowed capturing of additional patient demographics including American Society of Anesthesiologists score, body mass index, and glenoid morphology.

A Comparison of Revision Rates for Osteoarthritis of Primary Reverse Total Shoulder Arthroplasty to Primary Anatomic Shoulder Arthroplasty with a Cemented All-polyethylene Glenoid: Analysis from the Australian Orthopaedic Association National Joint Replacement Registry.

Background: There has been decreased use of anatomic total shoulder arthroplasty (aTSA) because reverse TSA (rTSA) is increasingly being used for the same indications. Although short-term studies generally have not found survivorship differences between these implant designs, these studies are often small and their follow-up is limited to the short term. Likewise, the degree to which patient characteristics (such as gender, age, and American Society of Anesthesiologists [ASA] score) may or may not be associated with survivorship differences calls for larger and longer-term studies than is often possible in single-center designs.

The rate of 2nd revision for shoulder arthroplasty as analyzed by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR).

Background and purpose - The increase in shoulder arthroplasty may lead to a burden of revision surgery. This study compared the rate of (2nd) revision following aseptic 1st revision shoulder arthroplasty, considering the type of primary, and the class and type of the revision.Patients and methods - All aseptic 1st revisions of primary total reverse shoulder arthroplasty (rTSA group) and of primary total stemmed and stemless total shoulder arthroplasty (non-rTSA group) procedures reported to our national registry between April 2004 to December 2018 were included.

The anteromedial approach for shoulder arthroplasty: the importance of the anterior deltoid.

Protection of the anterior aspect of the deltoid muscle is critical to the success of shoulder arthroplasty. Between 1975 and 1980, 75 patients with 81 shoulder arthroplasties had exposure via the anteromedial approach with careful anterior deltoid detachment through fascial tissues, systematic repair, and standardized rehabilitation with early passive range of motion. As with other reports on arthroplasty, pain was significantly reduced and motion was improved.
