Arthritis literally translates as joint inflammation. Osteoarthritis is the most common type of knee arthritis, it is also called wear-and-tear arthritis or degenerative joint disease. Osteoarthritis is characterised by progressive wearing away of the articular cartilage (joint surface) of the joint. As the protective cartilage surface is worn away it may become roughened and eventually bare bone may be exposed within the joint.

Who is at risk?
Knee arthritis typically affects patients over 50 years of age. It is more common in patients who are overweight. Weight loss in conjunction with muscle conditioning tends to reduce the symptoms associated with knee arthritis. There is also a genetic predisposition to this condition, meaning knee arthritis tends to run in families. Other factors that can contribute to developing knee arthritis include previous trauma to the knee, such as large meniscus tears, major ligament damage, and fractures to the bone around the joint.

Knee arthritis symptoms tend to progress as the condition worsens.It should be noted that a significant proportion of the population with knee arthritis will not suffer signifiacant symptoms. What is interesting about knee arthritis is that symptoms do not always progress steadily with time. Often patients report good months and bad months, or symptoms that fluctuate with the weather. This is important to understand because comparing the symptoms of arthritis on one particular day may not accurately represent the overall progression of the condition. Flares of symptoms can last up to 18 months.

The most common symptoms of knee arthritis are:
  • Pain with activities
  • Stiffness of the knee
  • Swelling of the joint
  • Limited range of motion
  • Tenderness along the joint
  • A feeling the joint may lock and give way
  • Deformity of the joint (knock-knees or bow-legs)

Spectrum of disease
Arthritis severity is based on the amount of wear out of the joint. Severe osteoarthritis is defined by the complete loss of joint surface as such, there is bone-on-bone wear out. This most frequently occurs on the inner side of the kneejoint but other focal areas of wear do occur.

Treatment of arthritis needs to be patiant specific but the severity of the wear will be a significant factor in determining treatment
