Long Term Mortality

Aims The aim of this study was to determine the long-term mortality rate, and to identify factors associated with this, following primary and revision knee arthroplasty (KA). Methods Data from the Scottish Arthroplasty Project (1998 to 2019) were retrospectively analyzed. Patient mortality data were linked from the National Records of Scotland. Analyses were performed separately for the primary and revised KA cohorts. The standardized mortality ratio (SMR) with 95% confidence intervals (CIs) was calculated for the population at risk. Multivariable Cox proportional hazards were used to identify predictors and estimate relative mortality risks. Results At a median 7.4 years (interquartile range (IQR) 4.0 to 11.6) follow-up, 27.8% of primary (n = 27,474/98,778) and 31.3% of revision (n = 2,611/8,343) KA patients had died. Both primary and revision cohorts had lower mortality rates than the general population (SMR 0.74 (95% CI 0.73 to 0.74); p < 0.001; SMR 0.83 (95% CI 0.80 to 0.86); p < 0.001, respectively), which persisted for 12 and eighteight years after surgery, respectively. Factors associated with increased risk of mortality after primary KA included male sex (hazard ratio (HR) 1.40 (95% CI 1.36 to 1.45)), increasing socioeconomic deprivation (HR 1.43 (95% CI 1.36 to 1.50)), inflammatory polyarthropathy (HR 1.79 (95% CI 1.68 to 1.90)), greater number of comorbidities (HR 1.59 (95% CI 1.51 to 1.68)), and periprosthetic joint infection (PJI) requiring revision (HR 1.92 (95% CI 1.57 to 2.36)) when adjusting for age. Similarly, male sex (HR 1.36 (95% CI 1.24 to 1.49)), increasing socioeconomic deprivation (HR 1.31 (95% CI 1.12 to 1.52)), inflammatory polyarthropathy (HR 1.24 (95% CI 1.12 to 1.37)), greater number of comorbidities (HR 1.64 (95% CI 1.33 to 2.01)), and revision for PJI (HR 1.35 (95% 1.18 to 1.55)) were independently associated with an increased risk of mortality following revision KA when adjusting for age. Conclusion The SMR of patients undergoing primary and revision KA was lower than that of the general population and remained so for several years post-surgery. However, approximately one in four patients undergoing primary and one in three patients undergoing revision KA died within tenten years of surgery. Several patient and surgical factors, including PJI, were associated with the risk of mortality within ten years of primary and revision surgery. Cite this article: Bone Joint J 2022;104-B(1):45–52.

Представлен случай использования модульной эндосистемы АМТ при ревизионном эндопротезировании коленного сустава у больного с ингибиторной формой гемофилии В. Эндопротезирование суставов у больных гемофилией занимает ведущую роль в оперативном ортопедическом лечении гемофилической артропатии. Хирургические вмешательства у пациентов с гемофилией связаны с высоким риском кровотечения и инфекции и проводятся на фоне заместительной гемостатической терапии. Выживаемость первичных эндопротезов коленного сустава у пациентов с гемофилией составляет около 80% при сроке наблюдения 10 лет. Тем не менее встречаются случаи, когда использование эпифизарных эндопротезов невозможно технически в связи с недостаточным массивом костной ткани. В таких случаях может потребоваться замещение дефекта костной ткани на значительном протяжении. Использование модульных эндопротезов позволяет частично или полностью замещать дефекты костей. В современной литературе описаны лишь единичные случаи использования модульных эндопротезов у больных гемофилией. Представлен клинический случай успешного применения модульного эндопротеза АМТ коленного сустава у больного с ингибиторной формой гемофилии В. The case is presented of modular endosystem AMT use in revision knee arthroplasty in a patient with an inhibitory form of hemophilia B. Arthroplasty in patients with hemophilia plays a leading role in the surgical orthopedic treatment of hemophilic arthropathy. Surgical treatment in patients with hemophilia is associated with a high risk of bleeding and infection, and is performed in conjunction with hemostatic therapy. The survival rate of primary knee arthroplasty in patients with hemophilia is about 80% with a follow-up period of 10 years. Nevertheless, there are cases when epiphyseal endoprostheses use is technically impossible, due to insufficient bone tissue. In these cases, it may be necessary to replace the bone defect over a considerable length. The use of modular endoprostheses allows partial or complete replacement of bone defects. Only a few cases of modular endoprostheses use in patients with hemophilia are described in the modern literature. The article presents a clinical case of successful application of a modular knee replacement AMT in a patient with an inhibitory form of hemophilia B.
