“…Subsequently a minimal (and negligible) increase in numbers performed per year was observed. This is in contrast with the expectation as published by Kurtz, since after the initial increase, we describe a stabilization in the incidence of THR in recent years 22, 23, 24. The increase in prevalence of patients with THR is most likely to be secondary to the increasing number of younger patients having surgery and the increasing life expectancy.…”

National Registers document changes in the circumstance, practice, and outcome of surgery with the passage of time. In the context of total hip replacement (THR), registers can help elucidate the relevant factors that affect the clinical outcome. We evaluated the evolution of factors related to patient, surgical procedure, socio‐economy, and various outcome parameters after merging databases of the Swedish Hip Arthroplasty Register, Statistics Sweden and the National Board of Health and Welfare. Data on 193,253 THRs (164,113 patients) operated between 1999 and 2012 were merged. We studied the evolution of surgical volume, patient demographics, socio‐economic factors, surgical factors, length‐of‐stay, mortality rate, adverse events, re‐operation and revision rates, and Patient Reported Outcome Measures (PROMs). Throughout this time period the majority of patients were operated on with a diagnosis of primary osteoarthritis. Comorbidity indices increased each year observed. The share of all‐cemented implants has dropped from 92% to 68%. More than 88% of the bearings were metal‐on‐polyethylene. Length‐of‐stay decreased by 50%. There was a reduction in 30‐ and 90‐day mortality. Re‐operation and revision rates at 2 years are decreasing. The post‐operative PROMs improved despite the observation of worse pre‐operative pain scores getting over time. The demographics of patients receiving a THR, their comorbidities, and their primary diagnosis are changing. Notwithstanding these changes, outcomes like mortality, re‐operations, revisions, and PROMs have improved. The practice of hip arthroplasty has evolved, even in a country such as Sweden that is considered to be conservative with regard taking on new surgical practices. © 2017 The Authors.

“…The growing demand for THA [16] coupled with age and increase in comorbidities of patients undergoing the procedure [12,13] warrants investigation of its current perioperative mortality rate. The primary focus of this paper was to determine overall mortality and causes of death at 30 and 90 days for patients undergoing THA.…”

“…Emerging demographic and epidemiologic studies are projecting large increases in the demand for primary and revision arthroplasty over the next two decades [14][15][16]. Furthermore, THA is being performed in patients who are older and infirm [1,12,13,21,22,35,38,41].…”

“…Although some authors have reported favorable outcomes after medial gastrocnemius flap coverage after TKA, with prosthesis retention rates as high as 82% to 92% [8,23,28], the largest English-language series to our knowledge included only 22 medial gastrocnemius flaps [6]. With an increasing number of patients undergoing TKA [14], the number of cases of periprosthetic joint infection also is increasing. Better understanding of outcomes after medial gastrocnemius flap coverage, including risk factors for treatment failure, will help to guide management of soft tissue defects in this setting.…”
