A ‘joint’ approach: design, implementation and preliminary outcomes of an early conservative knee and hip osteoarthritis service in northern New South Wales, Australia.

Australia is facing a growing burden of knee and hip osteoarthritis (OA). To address this demand in northern New South Wales, a community health-based conservative OA joint management service was established in the Tweed Valley. This paper describes the design, implementation and initial evaluation of the service. Following the principles of clinical redesign, a diagnostic phase involving consultation with key stakeholders revealed several issues. OA patients could wait up to 9 months for review by orthopaedic specialist following GP referral and received limited information on how to conservatively manage their conditions. GPs were constrained by short consultations and had limited knowledge of the latest recommendations for the conservative treatment of OA. GPs also highlighted the limitations of outdated fax systems for communication, noting their preference for secure electronic messaging. Based on these findings, the Tweed Knee and Hip Arthritis Service was established. For patients not on a waiting list for surgery, the service provides evidence-based conservative management for knee or hip OA involving standardised assessment, education, exercise, self-management strategies and regular review. An analysis of a foundational cohort of patients demonstrated improvements in a suite of validated and standardised measures for pain and function, with improvements seen as early as 1 month and sustained for 6 months. The study findings support the introduction of integrated conservative OA management models of care directly available to primary healthcare providers.

Management of periprosthetic joint infection after total hip arthroplasty using a custom made articulating spacer (CUMARS); the Exeter experience.

Periprosthetic joint infection (PJI) after THA is a major complication with an incidence of 1%-3%. We report our experiences with a technique using a custom-made articulating spacer (CUMARS) at the first of two-stage treatment for PJI. This technique uses widely available all-polyethylene acetabular components and the Exeter Universal stem, fixed using antibiotic loaded acrylic cement. Seventy-six hips were treated for PJI using this technique. Performed as the first of a two-stage procedure, good functional results were commonly seen, leading to postponing second stage indefinitely with retention of the CUMARS prosthesis in 34 patients. The CUMARS technique presents an alternative to conventional spacers, using readily available components that are well tolerated, allowing weight bearing and mobility, and achieving comparable eradication rates.
