Statistics from

Total knee arthroplasty (TKA) is an effective surgery for patients with advanced knee arthritis refractory to medical treatment. Gout, the most common inflammatory arthritis in adults, was associated with a 40% increased TKA risk in women in a recent population-based study.1 This was attributable possibly to accelerated cartilage wear associated with soluble urate or urate crystals. It is not known if post-TKA healthcare utilisation and complications are higher in people with gout. We assessed whether gout was associated with a higher risk of post-TKA healthcare utilisation and in-hospital complications.

We used the 1998–2014 US National Inpatient Sample data, a 20% stratified sample of discharges from US community hospitals.2 We used validated International Classification of Disease, ninth revision, common modification (ICD-9-CM) code to identify the primary TKA cohort (81.54)3, with TKA as the primary procedure and among these people with and without gout (274).4 Study outcomes post-primary TKA were (1) healthcare utilisation, length of hospital stay (>3 days) and the discharge disposition, that is, to home versus rehabilitation/in-patient facility; and (2) in-hospital postoperative complications identified by respective ICD-9-CM codes for transfusion, revision or infection, …
