Robotic-assisted versus conventional total knee arthroplasty: an updated systematic review and meta-analysis of randomized controlled trials with grade assessment

Moayad Mosleh, Ahmed Eldesouky, Mohamedhen Vall Nounou, Mohammed Bahlol et autres

Robotic-assisted total knee arthroplasty (RTKA) has been increasingly adopted to improve surgical precision during primary TKA. Although previous evidence suggests that RTKA may reduce alignment variability and radiographic outliers, whether these technical advantages translate into clinically meaningful improvements over conventional TKA (CTKA) …

Plasma-sprayed 45S5-bioactive glass coating provides superior anti-biofilm activity compared to hydroxyapatite coating while maintaining host cell cytocompatibility and antibacterial immune activation

Elisabeth Seebach, Jan Philippe Kretzer, Therese Bormann, Jens Gibmeier et autres

Periprosthetic joint infections (PJIs) are a major complication in joint arthroplasty, leading to higher mortality, poorer outcomes, and increased failure rates in revision surgeries. Revision challenges include patient risk factors, bacterial resistance, and the need for implants that combine biological integration with …

Transcriptomic response of human mesenchymal stromal cells exposed to Boron- and Molybdenum-substituted mesoporous bioactive glass nanoparticles

E. Kunisch, Q. Nawaz, T. Walker, Tobias Renkawitz et autres

Substitution of mesoporous bioactive glass nanoparticles (MBGNs; composition in mol%: 70 SiO2- 30 CaO) with therapeutically active ions such as Molybdenum (Mo) ions modulates their osteogenic properties. To overcome the limited pro-angiogenic capability of MBGNs, a combination of Mo with pro-angiogenic boron …

Impact of 45S5-Bioactive Glass on Chondrocytes in Knee Osteoarthritis—In Vitro Study Exploring Cellular Responses

M. Marinescu, Sebastién Hagmann, Jörg Fellenberg, Elena Tripel et autres

Osteoarthritis (OA), the most common joint disease, is marked by cartilage degradation and chronic inflammation. While 45S5-bioactive glass (45S5-BG) is well-established in bone regeneration and has been suggested to exert immunomodulatory effects, its impact on OA chondrocytes remains largely unexplored. Therefore, this …

Mesoporous bioactive glass nanoparticles exhibit intrinsic angiogenic potential in the chorioallantoic membrane assay, without the addition of exogenous cells

M. Moll, Qaisar Nawaz, Elke Kunisch, Tobias Renkawitz et autres

Angiogenesis is an essential part of bone regeneration, as neovascularisation supports the supply of necessary oxygen, nutrients, and cellular transport. Bioactive glasses (BGs) have shown promise in enhancing both angiogenesis and bone regeneration. For the evaluation of the angiogenic potential of BGs, …
