Methods
This study was a retrospective, population-based analysis of hospital administrative data, linked to provide longitudinal information about readmissions and death. We selected all patients with an admission containing a procedure code indicating an elective knee arthroscopy (Table 1) from July 1, 2000, to June 30, 2009. We included all endoscopic knee procedures with a therapeutic intervention, including ligament reconstruction. Patients were excluded if they had an additional procedure
Cohort Characteristics
After excluding 16,807 patients (8.5%) with an additional procedure during their admission, we identified 180,717 episodes involving an elective knee arthroscopy for 150,490 patients. The majority of procedures were same-day procedures (79.3%) performed in private hospitals (73.6%) in patients aged 40 to 59 years (45.1%). Public hospitals were less likely to have high elective orthopaedic volume compared with private hospitals (17.4% compared with 23.7%, P < .01). A concomitant definition of OA
Discussion
We quantified the frequency of adverse outcomes after elective knee arthroscopies in Victoria, Australia, and identified associated risk factors in a population-based cohort of 180,717 elective arthroscopies across a 9-year period. We found that 6.4 adverse events within 30 days are experienced per thousand arthroscopic procedures. The majority of the adverse event burden within 30 days is explained by VTE (4.0 per 1,000 procedures), which was associated with 12 deaths within 30 days (21.8% of
Conclusions
Our study found 6.4 adverse outcomes per 1,000 elective knee arthroscopy procedures (0.64%), with the 3 most common complications being DVT, effusion and synovitis, and PE. We have also identified risk factors for adverse outcomes, particularly chronic kidney disease, myocardial infarction, cerebrovascular accident, and cancer.Variable Definition OA of knee ICD-10-AM codes M17.0-M17.9 throughout any diagnosis code Year of arthroscopy Financial year (July 1 to June 30)
