ASA Class Is a Stronger Predictor of Early Revision Risk Following Primary Total Knee Arthroplasty than BMI.

Background: Although there is a known correlation between obesity and revision risk following total knee arthroplasty (TKA), there is an ongoing debate regarding the appropriateness of denying TKA solely based on the body mass index (BMI) of a patient. Our aim was to determine whether a patient's American Society of Anesthesiologists (ASA) class predicts their risks of early all-cause revision and revision for periprosthetic joint infection (PJI) following primary TKA, independent of their BMI.

Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) were obtained regarding all patients who underwent primary TKA for osteoarthritis in Australia from January 1, 2015, to December 31, 2022.

Patient and Surgical Factors Associated With Long-Term Mortality Outcomes Up to Fifteen Years After Total Hip and Knee Arthroplasty: An Australian Orthopaedic Association National Joint Replacement Registry Study.

Background: Mortality rates following total hip arthroplasty (THA) and total knee arthroplasty (TKA) arthroplasty display distinct temporal patterns often attributed to patient selection bias, perioperative optimization, and comorbidities. Understanding these mortality patterns is essential for epidemiological and health economic longitudinal modeling.

Methods: We conducted a national registry-based cohort study in Australia using data from 1999 to 2022, examining primary and revision THA and TKA procedures for osteoarthritis.

Australian general practitioners' perception of modifiable risk factors in reducing infective complications following hip and knee joint replacement.

Background And Objectives: Smoking, poor diabetic control and excessive body mass index (BMI) increase the risk of infection following joint replacement. This study investigated Australian general practitioners' (GPs) perception of these modifiable risk factors in patients with end-stage osteoarthritis.

Method: A structured online survey tool was developed and widely distributed to Australian GPs.

Lifetime Cost-Effectiveness of Structured Education and Exercise Therapy for Knee Osteoarthritis in Australia.

Importance: Structured education and exercise therapy programs have been proposed to reduce reliance on total knee replacement (TKR) surgery and improve health care sustainability. The long-term cost-effectiveness of these programs is unclear.

Objectives: To estimate the lifetime cost-effectiveness of implementing a national structured education and exercise therapy program for individuals with knee osteoarthritis with the option for future TKR compared with usual care (TKR for all).
