Influence of bone density on morphologic cement penetration in minimally invasive tibial unicompartmental knee arthroplasty: an in vitro cadaver study

Journal of Orthopaedic Surgery and Research, 2019
Background Unicompartmental knee arthroplasty is an established treatment option for anteromedial osteoarthritis. However, large registry studies report higher rates of aseptic loosening compared to total knee arthroplasty.

Preparation, physical-chemical characterisation and cytocompatibility of calcium carbonate cements [PDF]

, 2006
The feasibility of calcium carbonate cements involving the recrystallisation of metastable calcium carbonate varieties has been demonstrated. Calcium carbonate cement compositions presented in this paper can be prepared straightforwardly by simply mixing

Gelatin/gentamicin sulfate-modified PMMA bone cement with proper mechanical properties and high antibacterial ability

Materials Research Express, 2022
With the aging of the population, the risk of osteoporotic vertebral compression fractures (OVCF) caused by osteoporosis increases rapidly. Surgeons often fill the bone defect with injectable polymethylmethacrylate (PMMA) bone cement through ...

Co-grinding significance for calcium carbonate–calcium phosphate mixed cement. Part I: effect of particle size and mixing on solid phase reactivity [PDF]

, 2011
In part I of this study we aim to evaluate and control the characteristics of the powders constituting the solid phase of a vaterite CaCO3–dicalcium phosphate dihydrate cement using a co-grinding process and to determine their impact on cement setting ...

Surface pretreatment for prolonged survival of cemented tibial prosthesis components: full- vs. surface-cementation technique

BioMedical Engineering OnLine, 2005
Background One of few persisting problems of cemented total knee arthroplasty (TKA) is aseptic loosening of tibial component due to degradation of the interface between bone cement and metallic tibial shaft component, particularly for surface cemented ...

An experimental and computational investigation of bone cement residual stresses [PDF]

, 2006
Hip arthroplasty is a common orthopaedic procedure with considerable success in alleviating hip joint pain and disability. To transfer loads from the prosthesis to the contiguous bone, self-curing polymethyl methacrylate, often referred to as bone cement,

Controlled release properties and final macroporosity of a pectin microspheres–calcium phosphate composite bone cement [PDF]

, 2010
The use of calcium phosphate cements (CPC) is restricted by their lack of macroporosity and poor drug release properties. To overcome these two limitations, incorporating degradable polymer microparticles into CPC is an attractive option, as polymer ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...
