Predicting Knee Damage with AI

How Combining MRI, Biochemical Markers, and AI Could Transform Osteoarthritis Care

Knee osteoarthritis (KOA) is one of the leading causes of disability worldwide, affecting about 303 million people. The disease slowly erodes cartilage, leading to pain, stiffness, and reduced mobility.

For up to 30% of patients, the condition progresses to the point of requiring total knee replacement. The challenge is that clinicians don’t have reliable tools to predict which patients will worsen quickly and which will stay stable.

Early and accurate predictions could mean more timely interventions, better quality of life and lower surgical costs.

What’s new: Researchers from Chongqing Medical University, using data from the NIH Osteoarthritis Biomarkers Consortium, developed the LBTRBC-M model.

It combines MRI radiomics (quantitative features from imaging), biochemical biomarkers from blood and urine and clinical variables like demographics and health history. The dataset included 594 patients and 1,753 MRI scans over two years.

The model performed well, with AUC values ranging from 0.880 to 0.913 for pain progression and joint space narrowing. In testing with 7 resident physicians, accuracy improved dramatically, from 46.9% without AI to 65.4% with it.

The bottom line: This study shows how combining multiple data types (not just imaging) can make a big difference in disease forecasting.

Unlike earlier models that relied on a single modality, LBTRBC-M gives a more complete picture of the disease trajectory.

While validation in larger, more diverse populations is needed, this approach means a future where AI helps doctors stratify patients by risk, treat them, and intervene before joint damage is irreversible.

Artificial Womb in Humanoid Form: China’s Proposal for the World’s First Robot Pregnancy Surrogate

A tech company in Guangzhou, China, is working on what could become the world’s first humanoid “gestation robot.” The humanoid is designed with an artificial womb in its abdomen to carry a fetus from conception through delivery.

A prototype is expected by 2026, with a price tag of under 100,000 yuan (about $13,900 USD).

The concept, unveiled at the 2025 World Robot Conference in Beijing, goes beyond being just an incubator. The fetus would grow in artificial amniotic fluid and receive nutrients through a hose, simulating natural pregnancy.

The firm says it has already spoken with Guangdong authorities about ethical and regulatory considerations.

At the same event, researchers also presented GEAIR, an AI-powered breeding robot that automates cross-pollination and seed production, showing how robotics is being applied in both healthcare and agriculture.

Even though the pregnancy robot wasn’t explicitly branded as AI-driven, the setting made something clear: AI, human health, and robotics are rapidly converging.

The real debate may not just be about whether this can work; it’s whether we, as a society, are prepared for machines to play a role in something so deeply tied to human identity and ethics.
