SymptomsAnatomy Osteoarthritis of the knee occurs when the joint surface
cartilage (also called hyaline cartilage, or articular cartilage) becomes worn
away, leaving the raw bone beneath exposed. The cartilage normally serves as a
“pad” or a bearing in the joint, and under normal conditions, the cartilage
bearing is even slicker than a hockey puck on ice. When the bearing wears away,
the result is a roughed joint surface that causes the pain and stiffness that
people associate with osteoarthritis.Initial symptoms Pain, swelling, and stiffness are the main symptoms of
knee arthritis. When it becomes more advanced, joint deformity (knock-knees or
bow-legs) can occur.Symptoms Pain, stiffness, swelling, and joint deformity are the
symptoms of arthritis of the knee.Progression Early in the course of arthritis, the symptoms can be
intermittent, perhaps related only to particular activities or sustained
activity. At that point, usually rest and avoiding the precipitating activity
will improve the symptoms.
As the arthritis worsens, the symptoms can become more
persistent or more severe, such that simply walking on level ground can result
in pain.
When
arthritis is severe, the pain with activities can linger even after the
activity stops, such that the knee can remain painful even after one stops
walking.Conditions with similar symptoms Other forms of arthritis can cause similar symptoms to
osteoarthritis of the knee; in particular, post-traumatic arthritis and
post-meniscectomy arthritis are almost indistinguishable in many cases from
osteoarthritis of the knee.
Rheumatoid arthritis, the next most common cause of
arthritis, can also affect the knee. It tends to cause other joints to be
involved, and often causes more of an inflammatory set of symptoms (swelling
and warmth, as well as pain), and can in fact effect other organ systems as
well.
The
diagnosis of osteoarthritis versus rheumatoid arthritis can be made by a
physician with experience in treating conditions of this type.
