1

Different Kinds of Cartilige

Physeal: growth plates

Fibrocartilage: at tendon and ligament insertions into bone

Elastic: found in trachea

Fibroeleastic: meniscus

Articular/Hylan: cover ends of bone forming joints

2

Articular Cartilage

Looks like a hardboiled egg. It is shiny, white, smooth, slippery with a very low coefficient of friction.

As the cartilage gets worn, striations are shown. Carilage ranges from grade 0 (healthy) to grade 4 (completely worn).

Depends on synovial fluid for nutrients.

3

Degenerative Joint Disease (DJD)

DJD is not the same as normal aging.

This is a failed attempt of the chondrocytes to repair damaged cartilage.

4

Primary Arthritis

Degenerative or auto-immune

5

Secondary Arthritis

VINDICATE

Can be caused by a LOT of things.

6

Radiographic Features of Arthritis

Joint space narrowing

Subchondral sclerosis

Sobchondral cysts

Osteophytes (joint trying to expand SA)

7

Management of Joint Arthritis

1. Relaign = osteotomy (good for 15+ years)

2. Replace = joint replacement

3. Obliterate = fusion or excision (last choice)

8

What Else to Examine for Knee Pain

You should always examine the hips. Always check what is above and below the joint. Hip problems can often manifest as knee problems.

9

N-Acetyl-D-Glucosamine

Used in the treatment of autoimmune diseases, such as arthritis.

10

Chondroitin

Used as treatment for osteoarthritis.

11

Methylsulfonylmethane

May be useful in treating osteoarthritis.

12

Osteoarthritis of Hip - Range of Motion Loss

The first range of motion to lose with osteoarthritis of the hip is internal rotation.

13

Treatment of Avascular Necrosis

If possible, identify and remove the inciting cause.

Pain management.

Supportive therapy.

Eventual joint replacement or fusion.

14

Charcot Joint

Also known as neuropathic arthropathy.

Progressive degeneration of a weight bearing joint. Classically presents as an unstable, painless, swollen joint.

Most common cause is diabetes in North America.
