Data of knee arthroplasty register of Vreden Russian Research Institute of Traumatology and Orthopedics for period 2011-2013

Abstract

The knee arthroplasty register was established in Vreden Russian Research Institute of Traumatology and Orthopedics on 01.01.2011 and during the following 3 years the data about 6530 primary (91,7%) and revision (8,3%) cases were collected. The average age of patients was 62,72 ±11,5 years with the prevalence of women both in primary (80%) and revision (70%) arthroplasty cohorts. The main group consisted from the patients with knee osteoarthritis (92%) with annual growth of the obese. Total cemented knee replacement without patella resurfacing was the most popular type of primary arthroplasty (96%) with the prevalence of PCL retaining implants (62,13±3,84%). Despite annual decrease of revisions due to infection they predominate under aseptic cases: in 2011 - 64,7% and 35,3%, in 2012 - 62,8% и 37,2% , in 2013 - 53,1% and 46,9% accordingly. The main reason for non-infected revision TKA was implant loosening (17%). This is the first attempt to describe the trends in knee arthroplasty based on data from register of Russian Research Institute of Traumatology and Orthopedics. It’s structure allows to perform multifactorial analysis of knee replacement surgeries and in the future to evaluate implants survival rate.

Factors Related to Postoperative Pain Trajectories following Total Knee Arthroplasty: A Longitudinal Study of Patients Admitted to a Russian Orthopaedic Clinic

“…Among our cohort of patients, we observed similar associations with gender and preoperative pain but found no association with age and could not evaluate the remaining factors. Women reported more pain than men ( p = .009), but the male subgroup consisted of only 7 patients, which reflects the typical gender distribution among primary TKA patients in our institution in recent years [ 49 ]. Patients who had a moderate to severe level of preoperative pain also reported more hours of moderate to severe pain during the first 3 postoperative days, ( p = .029), although preoperative pain was unrelated to postoperative pain in activity.…”

Fungal Periprosthetic Infection after Total Knee Arthroplasty (Case Report and Review)

“…Р.Р. Вредена демонстрируют, что более 58% всех ревизионных вмешательств выполнены с целью лечения ППИ [5,6]. Подтверждением этой тенденции служит и изменение структуры реэндопротезирования коленного сустава.…”

“…Р.Р. Вредена расшатывание компонентов эндопротеза является самой частой причиной асептических ревизионных вмешательств и составило 15% в 2011 году, 19,9% в 2012 году и 16,1% в 2013 году (по отношению к общему количеству асептических ревизионных вмешательств) [7]. По данным ре-гистра Англии и Уэльса асептическое расшатывание и лизис явились причиной ревизионного эндопротезирования коленного сустава в 40% случаев [8].…”
