Keywords used: osteoarthritis, knee, treatment, definition, exercises, surgery, condition (or a combination of these words).
Definition/Description[edit | edit source]
Knee osteoarthritis is the occurrence of osteoarthritis (OA) in the knee joint. The OA can be diagnosed in 3 places within the knee:
a. Medial compartment
b. Lateral compartment
c. Patellofemoral compartment
Clinically Relevant Anatomy[edit | edit source]
As mentioned above OA in the knee occurs in the patellofemoral joint as well as in the tibiofemoral joint. (Figure1.)
Other important factors are:
- Quadriceps strenght
- Alignment of the femur and tibia ( valgus/varus)
- (age and weight)
Epidemiology /Etiology[edit | edit source]
Osteoarthritis can be catalogued in 2 types:
Type I: this type of OA is mostly related to aging, there is no other disease or trauma causing the condition.
With age the water level in the articulate cartilage rises and makes the cartilage less solid. The production of proteins that are used in the maintenance of the cartilage also decreases, making the cartilage more vulnerable to ruptures.
Type II: In this type of OA there is another condition or disease causing the OA
for example: obesity, diabetes, surgery to joint structures, repeated trauma...
In the early stage in an osteoarthritis affected knee joint the cartilage will start show signs of wear, tiny crevasses or ruptures. If no effort is made to slow down or stop this process the cartilage will then further degenerate and pieces of the cartilage “cushion” between the bones of the affected joint will be gone. This will affect the functioning of the underlying bone, making them deform, form bone spurs and such endangering the function of the joint. [1]
Also the synovial membrane can be agitated and cause periodic inflammation. [2]
