Quantifying the excess cost and resource utilisation for patients with complications associated with elective knee arthroscopy: a retrospective cohort study.

Background: Recent studies have demonstrated morbidity associated with elective knee arthroscopy. The objective of the current study was to quantify resource utilisation and costs associated with postoperative complications following an elective knee arthroscopy.

Methods: We undertook a retrospective, longitudinal cohort study using routinely collected hospital data from Victorian public hospitals during the period from 1 July 2000 to 30 June 2009.

Lifetime risk of total knee replacement and temporal trends in incidence by health care setting, socioeconomic status, and geographic location.

Objective: To estimate the lifetime risk of total knee replacement (TKR) and examine temporal trends in TKR incidence in the state of Victoria, Australia.

Methods: We performed a retrospective analysis of a population-based longitudinal cohort of patients (ages ≥40 years) who received a primary TKR in Victoria from 1999-2008. Hospital separations and life tables were used to estimate lifetime risk.

Adverse outcomes associated with elective knee arthroscopy: a population-based cohort study.

Purpose: The aims of this study were to quantify the frequency of adverse outcomes after elective knee arthroscopies in Victoria, Australia, and to identify risk factors associated with adverse outcomes.

Methods: We performed a retrospective, longitudinal cohort study of elective orthopaedic admissions using the Victorian Admitted Episodes database, a routinely collected public and private hospital episodes database linked to death registry data, from July 1, 2000, to June 30, 2009. Adverse outcome measures included pulmonary embolism (PE), deep vein thrombosis (DVT), hemarthrosis, effusion and synovitis, cellulitis, wound infection, synovial fistula, acute renal failure, myocardial infarct, stroke, and death.

Osteolysis in patients with a metal-on-metal hip arthroplasty.

Background: Despite design and manufacturing improvements in contemporary metal-on-metal hip replacements, the problem of wear particles persists. The local and systemic biological consequences of this ionic debris have been the subject of much investigation and it has become clear that cell-mediated delayed-type hypersensitivity reactions are a discrete mode of osteolysis in susceptible patients.

Methods: We have carried out a consecutive series of 125 primary hip replacements using the Metasul (Zimmer, Warsaw, IN, USA) bearing couple.
