According to a study published in The American Journal of Sports Medicine, men and women with a history of knee injuries in the past year experienced significantly lower Knee Injury and Osteoarthritis Outcome scores compared with uninjured patients.
Researchers administered KOOS to 999 patients or accompanying family members seen at an outpatient orthopedic clinic in July 2014 for an orthopedic issue unrelated to their knee. In the final study cohort, 402 men and 597 women were included.
Here are three points:
1. Compared with other subscales, men and women scored lower on the symptoms subscale, with men scoring lower in all age cohorts except the 56-year-old to 64-year-old age group.
2. Researchers found lower median scores for the pain and knee-related quality of life subscales in the 56-year-old to 64-year-old female cohort versus the 18-year-old to 55-year-old female cohort.
3. Researchers noted significantly lower KOOS scores in the 3 percent of patients who reported a history of knee injuries in the previous year versus uninjured participants.
