Research reveals bone loss after shoulder replacement surgery

After shoulder replacement surgery, bone density around the implant declines over time, according to a new study. The findings highlight the importance of assessing osteoporosis before surgery.

Advancing hip fracture prediction with AI

An AI tool built from Swedish national health registry data can predict hip fracture risk, and identify more at-risk individuals than current clinical screening practices, according to a new study.

Implant failure and osteoporosis: “two sides of the same coin”

A new position statement urges orthopaedic surgeons and bone health specialists to work together to assess and treat osteoporosis before and after joint replacement and spinal fusion surgery.

Hip replacement: Study shows benefits of dual mobility-THR

Using dual mobility total hip replacements (DM-THR) instead of the standard THR approach greatly reduces the likelihood of dislocation post-surgery, a new study finds.

Mako robotic shoulder replacement makes European debut

A Dublin hospital completed Europe's first robotic-assisted shoulder replacement using Stryker's Mako platform, expanding the technology beyond hip and knee surgery.

Lasting relief for knee pain – without surgery

For patients with knee osteoarthritis, for whom injections no longer provide sufficient relief, but joint replacement is also not an option, a minimally invasive treatment might offer an alternative.

News • Reduced rate of reoperation

Six-year study reveals benefits of robotic total hip replacement

Total hip replacement performed with robotic techniques has a lower reoperation rate than the conventional procedure, according to a six-year study.

News • Bone healing ‘superpower’

Wrist fracture in children: Trial favours cast-first approach

Most children with a broken wrist can be treated without surgery, a major trial finds, suggesting that a cast-first approach delivers similar long-term recovery while reducing risks and costs.

Radiation for joint pain? Study validates low-dose approach for knee osteoarthritis

The concept of using radiotherapy for osteoarthritis may seem counterintuitive for many clinicians. Yet a well-designed randomised controlled trial presented at the 2025 ASTRO Annual Meeting in San Francisco suggests that low-dose radiotherapy deserves a closer look. The findings add robust evidence to a therapeutic approach that has long been underutilised outside of German-speaking countries.

News • Gait biomechanics analysis

AI predicts success of hip surgery

Researchers at Karlsruhe Institute of Technology (KIT) have developed an AI model to predict how well patients with hip osteoarthritis will be able to walk again after an operation.

News • Critical areas for osteoporotic fractures

Predicting hip fractures from just 7% of the bone

To predict the risk of hip fracture, only 7% of the bone mass needs to be analysed, a new study finds. Scientists have identified these critical areas to improving diagnostic methods.

Avoidable knee surgery cancellations: a costly, painful problem

Thousands of NHS knee replacement operations are cancelled at short notice every year, many for avoidable reasons, a new study shows. This costs the NHS millions of pounds and increases waiting times.

News • Human-robot symbiosis

Prosthetic technology to restore natural walking after amputation

Researchers developed an algorithm for personalizing robotic prosthetic devices to optimize the movement of the prosthetic limb and also help a user’s body engage in a more natural walking pattern.

News • New cannula design

Surgical device increases range of motion in hip arthroscopy

Engineers have developed a new surgical device for hip arthroscopy which they hope will completely change procedures in the hip region, making them safer and more efficient than before.

News • Preventing periprosthetic femoral fractures

Safer implant designs for total hip replacement

Postoperative femoral fracture—a break in the thigh bone near the hip joint—is a common complication after total hip replacement. A new study explores how implant design can reduce this risk.

News • Orthopedic ultrasound screening

AI helps spot signs of dysplasia in infant hips

Developmental dysplasia of the hip occurs in 2-4% of infants, but screening via ultrasound is notoriously hard to master. An AI-assisted application could prevent many unnecessary hospital referrals.

AI predicts future X-rays of osteoarthritis patients

An AI system that can predict what a patient’s knee X-ray will look like a year in the future could transform how millions of people with osteoarthritis understand and manage their condition.

Fixing bone fractures with a glue gun? Not as crazy as it sounds

Historically, implants to repair bone fractures have been made of metal, donor bone, or 3D-printed material. Now, scientists propose an in-situ printing approach - using a modified glue gun.
