Radiographic patterns and associations of osteoarthritis of the knee in patients referred to hospital
Article Abstract:
Patients referred to the hospital for osteoarthritis of the knee may often have radiographic changes in both sides and in more than one compartment of their knee. Osteoarthritis is a noninflammatory degenerative joint disease that mainly occurs in older individuals. Among 252 patients between 34 and 91 years old with osteoarthritis of the knee who were X-rayed, 85% had radiographic changes in both sides of their knee. Among 470 knees, 59% had changes in two compartments and 6% had changes in three compartments. Men were more likely to have changes on only one side of their knee than women. Many patients had deposition of calcium pyrophosphate crystals in their knee.

Screening for pain in knee osteoarthritis: which question?
Article Abstract:
The types of information collected about pain prevalence can be significantly altered by subtly changing the wording of survey questions. Researchers surveyed 4057 people aged 40 to 79 years about knee pain frequency using a three-question survey and later examined the knees of 459 respondents. Pain frequency varied from 19.3% to 28.3% depending on whether the question asked if knee pain lasting for a month ever occurred, occurred within the last year, or occurred in the last month. Respondents who had frequent pain in the last month were more likely to have measurable knee damage.
