What is the function of articular cartilage?

What is the function of articular cartilage?

I'll articulate: There are several reasons for the articular cartilage, depending on the location. Generally though it reduces friction, reduces stress on the underlining bone and helps equalize the load bearing pressure. ...Read more

Cartilage (Definition)

Cartilage is a specialized type of tissue found in joints and areas that two bones come together. It is made up of specialized cells that live in the midst of proteins and sugars that absorb and release water similar to a sponge. Healthy cartilage helps decrease friction in joints, absorbs shock and protects the ends of the bone. Degradation of ...Read more

What can positively affect the health of our articular cartilage?

What can positively affect the health of our articular cartilage?

Motion, weight loss: Motion (via non-impact aerobic exercise- walking, biking, swimming) definitely helps maintain the functionality of articular cartilage. Decreased load across a weight bearing joint (e.g. knee) via weight loss is also a major help toward improving the health of articular cartilage ...Read more

Difference between articular cartilage and condyles?

Difference between articular cartilage and condyles?

Definitions: Articular cartilage refers to the lining of the bones in a joint (such as the knee, hip, shoulder, and wrist). It is an amazing dynamic structure that cushions the joint while allowing it to move freely. Condyles refer to anatomic parts of bones that look like rounded pegs (examples are the femoral condyle of the knees. Elbows, fingers, and toe joints also have "condyles"). ...Read more

Did exercise help or hinder your recovery from articular cartilage repair?

Help: Motion of effected joint and nonimpact activity appear to be valuable for cartilage nutrition and recovery from restoration procedures. By nonimpact I am referring to activities like swimming, cycling, walking which are safe in intermediate stages( 3 mos to 6-8 mos) after such procedures. Higher impact activites probably shouldn't even be considered until 10-12 mos post operatively. ...Read more

Cartilage is cartilage and bone is bone. Articular cartilages lie over some spongy bone and bone gets more dense further down. The cartilage helps to protect the bone, lubricates, absorbs impact. ...Read more

How does articular cartilage damage affect recovery from partial meniscectomy?

How does articular cartilage damage affect recovery from partial meniscectomy?

Slows recovery: Meniscus tears resolve quickly after partial meniscectomy. The finding of cartilage damage puts a cloud over your recovery and ability to return to running. It will definitely slow it up to 6 weeks. The grade, location and size of the area of cartilage damage will ultimately come ino play. Articular damage often has no effect. Remain positive do physical therapy and listen to doc. ...Read more

Has anyone had arthroscopic surgery for articular cartilage repairing?

Has anyone had arthroscopic surgery for articular cartilage repairing?

Certainly: I haven't had it done to myself, but the surgery is often performed on new cartilage tears where we can put back the piece that has torn or broken off. We often fix them with absorbable screws that the body will take away over time. The articular cartilage is not very forgiving, so a damaged portion of cartilage is often permanently damaged. In those cases, there are transplantation options. ...Read more

What does chondrocalcinosis mean in the knee? What does fibrillation of the articular cartilage posteriorly mean?

Arthritic changes: Chondocalcinosis is a condition with deposition of calcium pyrophosphate dihydrate crystals in the articular or joint surface cartilage (white stuff on the end of a chicken bone) that leads to arthitic changes. Fibrillation is early arthritic change with fraying of the articular catilage giving the surface the appearance of an unmowed lawninstead of a smooth surface. Posterior is back of joint. ...Read more
