Recovery from knee arthroplasty

After the knee arthroplasty operation recovery is usually rapid. In the hospital right after surgery early knee movement, within the first 24 hours, is encouraged. Recovery times can vary depending on the individual and the type of surgery carried out. Antibiotics and pain relief following knee arthroplasty The patient is provided with antibiotics to prevent infection and adequate pain relief […]

Could prosthetic limbs one day be controlled by human thought?

For almost two decades, Stanford electrical engineering professor Krishna Shenoy and neuroscientists in his Neural Prosthetics Translational Laboratory have been working on implantable brain sensors that allow them to record and decipher the electrical activity of neurons that control body movement. The long-term goal: to build prosthetics that amputees and those with paralysis can control with their thoughts. Currently, the […]

Prosthetic valve mismatches common in transcatheter valve replacement, ups risk of death

In the largest multi-institutional study to date, led by researchers from Penn Medicine, the team found that among patients who underwent a transcatheter aortic valve replacement (TAVR), a high number experienced severe and moderate cases of prosthesis-patient mismatch (PPM)—meaning the implanted heart valve is too small for the patient which can lead to inadequate blood flow. The team also found […]

Surgical technique improves sensation, control of prosthetic limb

Humans can accurately sense the position, speed, and torque of their limbs, even with their eyes shut. This sense, known as proprioception, allows humans to precisely control their body movements. Despite significant improvements to prosthetic devices in recent years, researchers have been unable to provide this essential sensation to people with artificial limbs, limiting their ability to accurately control their […]
