Survivorship and Functional Outcomes of Cementless versus Cemented Total Knee Arthroplasty: A Meta-Analysis

J Knee Surg DOI: 10.1055/s-0039-1678525The purpose of this meta-analysis was to assess the evidence supporting the use of cementless versus cemented total knee arthroplasties (TKAs). Specifically, we evaluated (1) all-cause survivorship, (2) aseptic survivorship, and (3) functional outcomes (Knee Society Scores [KSS], Oxford Knee Scores, Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] scores, and ranges of motion [ROMs]). A literature search was performed for studies that evaluated cementless versus cemented TKAs published between 2000 and 2017. Selected studies included three randomized controlled trials, three retrospective observational studies, and one prospective observational study that met the following criteria: (1) primary TKAs, (2) compared cementless and cemented TKAs, (3) implant survivorship that described the causes of failure, and (4) at least one functional outcome. To compare the two cohorts, pooled odds ratios (OR) and 95% confidence intervals (95% CI) were used to calculate tibial and femoral implant survivorship, and pooled mean differences (MD) and 95% CI calculated the functional scores and ROMs. Based on pooled data from the few number of studies, cementless TKAs had a better all-cause survivorship (OR = 0.37; 95% CI, 0.15–0.92) and tended to have a better aseptic survivorship (OR = 0.44; 95% CI, 0.17–1.14). However, this is likely due to the 83.3% weight of the single cementless study poten...

BMPs, TGFβ, and border security at the interzone. Curr Top Dev Biol. 2019;133:153-170 Authors: Lyons KM, Rosen V Abstract Synovial joints enable movement and protect the integrity of the articular cartilage. Joints form within skeletal condensations destined to undergo chondrogenesis. The suppression of this chondrogenic program in the interzone is the first morphological sign of joint formation. While we have a fairly good understanding of the essential roles of BMP and TGFβ family members in promoting chondrogenic differentiation in developing skeletal elements, we know very little about h...

The objectives of the present narrative review were to identify, summarize, and cluster all the potentially modifiable risk factors that influence the course of KOA, and discuss their susceptibility to alteration via personal, clinical, and public strategy. For this purpose, Pubmed and Scopus databases were queried using the terms “knee osteoarthritis”, “risk factors” and “improvement”. Six main categories of modifiable risk factors were identified: (1) obesity and overweight, (2) comorbidity, (3) occupational factors, (4) physical activity, (5) biomechanical factors, (6) dietary exposur...

This study compared ESWT, Wharton's jelly mesenchymal stem cells (WJMSCs) and combination of ESWT and WJMSCs therapies for early OA of the rat knee. The results showed ESWT, WJMSCs and combination of therapies significantly improved early OA knee based on analysis of pathological findings, micro-CT and immunohistochemistry (IHC) stain. The combined therapy group increased the bone volume (61.755 ± 1.537), and trabecular thickness (0.215 ± 0.014; P

Authors: Li L, Yang X, Yang L, Zhang K, Shi J, Zhu L, Liang H, Wang X, Jiang Q Abstract The purpose of this study was to determine the effect of the degenerative medial meniscus and traumatic lesions on the biomechanical behavior of the knee. An elaborate three-dimensional (3D) finite element model of the total knee joint containing bones, articular cartilages, main ligaments, and menisci was developed from a combination of magnetic resonance images and computed tomography. Three types of meniscus tears were employed to represent the degenerative and traumatic lesions. The stress and meniscus extrusion of healthy a...

Regional variations also exist for socioeconomic status. We analyzed the association between socioeconomic deprivation (SED) and knee replacement (KR) incidence and assessed the proportion of KR associated with affluence.Methods:Patients aged 15 years and over hospitalized for KR in 2013 were included. We linked each patient to a municipality of residenc...
