Necessary Factors to Achieve Deep Flexion for Asian Populations after Oxford Unicompartmental Knee Arthroplasty

The objective of this study was to clarify the relationship between outcomes and the postoperative maximum flexion angle and reveal the necessary factors for maximum flexion angle ≥ 140 degrees which is considered necessary for Asian populations. We categorized 212 UKA patients into the following three groups based on the postoperative maximum flexion angle: group 1 had flexion angle ≥ 140 degrees in 80 patients (38%), group 2 had 130 degrees ≤ flexion angle

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...
