Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage.

Immune cells formed in inflamed skin can travel through the blood and reach the joints, where they sometimes trigger inflammation. The key difference lies in the joint’s ability to keep those cells in check. This insight could help doctors identify warning signs early and prevent lasting joint damage.

By blocking a protein linked to aging, the therapy restored healthy, shock-absorbing cartilage in old mice and injured joints, dramatically improving movement and joint function. Human cartilage samples from knee replacement surgeries also began regenerating when exposed to the treatment.

They discovered that distinct regions activate for facial versus limb pain, showing the brain’s built-in precision pain control system. The findings could lead to targeted, non-opioid treatments that use cannabinoid mechanisms instead of opioids, offering safer pain relief options.

Therefore, researchers are developing cartilage implants using cells from the patient's nasal septum. A recent study shows that giving these cartilage implants more time to mature significantly improved clinical efficacy, even in patients with complex cartilage injuries. This suggests that the method could also be suitable for the treatment of degenerated cartilage in osteoarthritis.

New material comprises peptides, proteins and polysaccharides that mimic the microstructure of natural cartilage. Within six months, researchers observed new cartilage growth.

Researchers found that intensifying the motion of molecules within the nanofibers led to more components needed for regeneration. After just four hours, the treatment activated the gene expression necessary to generate cartilage. Therapy could be used to treat osteoarthritis, which affects nearly 530 million people worldwide.

According to researchers, if two copies of this mutated gene (known as IKBKB) are present, patients with psoriasis may go on to develop psoriatic arthritis, leaving them with joint pain, stiffness and swelling. It's hoped the findings will lead to improved diagnosis and treatment for patients with psoriasis and psoriatic arthritis -- conditions that patients say carry stigma in the community.

Mimicking articular cartilage, found in our knee and hip joints, is challenging. This cartilage is key to smooth joint movement, and damage to it can cause pain, reduce function, and lead to arthritis. One potential solution is to implant artificial scaffolds made of proteins that help the cartilage regenerate itself as the scaffold biodegrades. How well the cartilage regenerates is linked to how well a scaffold can mimic the biological properties of cartilage, and to date, researchers have struggled to combine the seemingly incompatible properties of stiffness and toughness. Now, new research outlines a method to marry these properties in a biodegradable gel.

The findings may inform better treatment targets and increase understanding of other conditions caused by aging tissues in the body.

As the popularity of health foods increases, scientists are searching for alternative sources of CSPGs. Now, researchers have analyzed the PGs and their CS structures in the head cartilage of 10 edible bony fishes, including sturgeons. Their findings point to several new fishes that can serve as alternatives to salmon as a source of CSPGs.

However, a new study reveals the importance of IL-6 and associated genes for maintaining and regenerating cartilage in both the joints and in the growth plates that enable skeletal growth in children. Scientists took a close look at a key gene activated by IL-6: STAT3. In both lab-grown human cells and in mice, the scientists demonstrated that STAT3 is critical for the proliferation, survival, maturation and regeneration of cartilage-forming cells in the joints and growth plates. When the gene ceased to function, cartilage-forming cells became increasingly dysfunctional over time, resulting in smaller body size, prematurely fused growth plates, underdeveloped skeletons and mildly degenerated joint cartilage.

The combination not only decreased arthritis inflammation markers in the cells but improved the production of desired proteins normally found in healthy cartilage. While still at an early stage, the findings suggest a new procedure could be developed to treat cartilage cells extracted from a patient to grow a supply of cells or a tissue to be re-implanted.

That combination of soft-yet-strong has been hard to reproduce in the lab.

New research finds that adult skates go one step further than cartilage growth: They can also spontaneously repair injured cartilage. This is the first known example of adult cartilage repair in a research organism. The team also found that newly healed skate cartilage did not form scar tissue.

Synthetic materials couldn't match it -- until "Kevlartilage" was developed.

Now, bioengineers have determined that microgravity may inhibit cartilage formation. Findings reveal that fracture healing for astronauts in space, as well as patients on bed rest here on Earth, could be compromised in the absence of mechanical loading.
