MOBILE and the provision of total joint replacement [PDF]
, 2008 Modern joint replacements have been available for 45 years, but we still do not have clear indications for these interventions, and we do not know how to optimize the outcome for patients who agree to have them done.

Advanced Science, EarlyView.Microparticle‐based antioxidants capable of scavenging multiple reactive oxygen species (ROS) have been developed. When retained within the articular cavity of osteoarthritic mice, Mn‐ or Co‐AKT‐MPs protect the inherent homeostasis between cartilage anabolism and catabolism, and inhibit synovial inflammation.

Theoretical and Applied Mechanics Letters, 2023 Researchers have proposed various linkage mechanisms to connect knee and ankle joints for above-knee prostheses, but most of them only offer natural walking. However, studies have shown that people assume a squatting posture during daily activities. This
