“…This interpretation was echoed by a previous study reporting that obesity was not a risk factor for TKA failures in Japanese patients [22]. On the other hand, the identified risk factors, male sex and younger age, concur with previous studies reporting a higher revision rate for younger patients [1,14,18,23,34,39,45], a higher association between wear and young age [19,37], and a higher incidence of infection in males [1,22]. However, this study does not provide clues to understand why male sex increases the risk for infection, and future studies are warranted to elucidate this issue and to reduce infection in male patients.…”

Background Failure after total knee arthroplasty (TKA) may be related to emerging technologies, surgical techniques, and changing patient demographics. Over the past decade, TKA use in Korea has increased substantially, and demographic trends have diverged from those of Western countries, but failure mechanisms in Korea have not been well studied.Questions/purposes We determined the causes of failure after TKA, the risk factors for failure, and the trends in revision TKAs in Korea over the last 5 years. The Knee Society, patient demographics, information on index and revision of TKAs, and indications for index TKA. The influences of patient demographics and indications for index TKA on the risk of TKA failure were evaluated using multivariate regression analysis. The trends in revision procedures and demographic features of the patients undergoing revision TKA over the last 5 years were assessed. Results The most common cumulative cause of TKA failure was infection (38%) followed by loosening (33%), wear (13%), instability (7%), and stiffness (3%). However, the incidence of infections has declined over the past 5 years, whereas that of loosening has increased and exceeds that of infection in the more recent 3 years. Young age (odds ratio [OR] per 10 years of age increase, 0.41; 95% confidence interval [CI], 0.37-0.49) and male sex (OR, 1.88; 95% CI, 1.42-2.49) were associated with an increased risk of failure. The percentage of revision TKAs in all primary and revision TKAs remained at approximately 3%, but the annual numbers of revision TKAs in the more recent 3 years increased from that of 2008 by more than 23%. Conclusions Despite a recent remarkable increase in TKA use and differences in demographic features, the causes and risk factors for failures in Korea were similar to

“…As the indications of TKA have been widened to include younger and more active patients, the demand for the revision procedure will be increasing. Odland et al [15] reported 10 of 59 patients (11 of 67 knees) had revisions for aseptic loosening and/or osteolysis in patients 55 years of age and younger with OA with a minimum followup of 10 years. We found age in the periprosthetic fracture subgroup was higher than that in the primary TKA group.…”

Background There is limited information regarding the cause of revision TKA in Asia, especially Japan. Owing to differences in patient backgrounds and lifestyles, the modes of TKA failures in Asia may differ from those in Western countries. Questions/purposes We therefore determined (1) causes of revision TKA in a cohort of Japanese patients with revision TKA and (2) whether patient demographic features and underlying diagnosis of primary TKA are associated with the causes of revision TKA. Methods We assessed all revision TKA procedures performed at five major centers in Hokkaido from 2006 to 2011 for the causes of failures. Demographic data and underlying diagnosis for index primary TKA of the revision cases were compared to those of randomly selected primary TKAs during the same period. Results One hundred forty revision TKAs and 4047 primary TKAs were performed at the five centers, indicating a revision burden of 3.3%. The most common cause of revision TKA was mechanical loosening (40%) followed by infection (24%), wear/osteolysis (9%), instability (9%), implant failure (6%), periprosthetic fracture (4%), and other reasons (8%). The mean age of patients with periprosthetic fracture was older (77 versus 72 years) and the male proportion in patients with infection was higher (33% versus 19%) than those of patients in the primary TKA group. There was no difference in BMI between primary TKAs and any type of revision TKA except other causes. Conclusions The revision burden at the five referral centers in Hokkaido was 3.3%, and the most common cause of revision TKA was mechanical loosening followed

“…Patient related factors also play a role on the rate of wear and osteolysis. Odland et al (22) found that implanting modular TKAs in younger active population may increase the risk of wear and osteolysis. Backside wear in modular tibial TKAs remains a challenging problem despite the marketing efforts by the manufactures.…”
