Asymptomatic Population Reference Values for Three Knee Patient-Reported Outcomes Measures: Evaluation of an Electronic Data Collection System and Implications for Future International, Multi-Centre Cohort Studies
Initiatives
-
The aim was to assess whether the Knee Society Score, Oxford Knee Score (OKS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) were comparable in asymptomatic, healthy, individuals of different age, gender and ethnicity, across two remote continents. The purpose of this study was to establish normal population values for these scores using an electronic data collection system.
Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.

The aim of this study was to assess whether the Knee Society Score (KSS), the Oxford Knee Score (OKS) and the Knee Injury and Osteoarthritis Outcome Score (KOOS), are equivalent in asymptomatic, healthy, pathology-free individuals of different age, gender and ethnicity, across two remote continents. The purpose of this study was to establish normal population values for the KSS, OKS and KOOS, using an electronic data collection system.
Selection Criteria
- Minimum age
-
18
- Newborns
- Twins
- Countries
-
- Canada
- Australia
- Ethnic Origin
-
- Health Status
-
- Participants reported both knees as “normal”
- Other criteria
- Exclusion criteria included participants with: a history of any inflammatory arthritis; significant lumbar spine problems that interfered with their mobility or function; or cognitive impairment or language problems. Participants were also excluded if they had active (i.e., painful or symptomatic) ipsilateral knee pathology; a history of ipsilateral knee joint arthroplasty; or ipsilateral knee surgery within the past 3 years. A history of inactive (i.e., no longer symptomatic) ipsilateral knee pathology, including previous surgery, was recorded, but was not considered part of the exclusion criteria. A history of active hip, ankle and/or foot pathology was recorded; as well as contralateral knee pathology.

Data Collection Event
Participants self-administered using an electronic mobile device (Smartphone, iPad or other electronic tablet device), or a laptop computer. If a participant had difficulty in completing the questionnaire, due to visual impairment, impaired dexterity, or computer unfamiliarity, a researcher completed it for them by verbally asking the questions and recording their responses.
