Background: Osteoarthritis (OA) knee pain is a global source of impairment. Detecting the site of pain represents an essential technique for diagnosing clinical issues and determining suitable treatments. This study aims to detect the pattern and site of knee pain in patients with knee OA confirmed by X-ray and their effect on the functional status.
Patients and Methods: a cross-sectional study including 100 patients with primary knee OA. The Photographic Knee Pain Map (PKPM) has been used to detect pain sites. The physical status has been defined.
Results: Most patients are females (88%). Most patients have experienced morning stiffness (79%) with a duration ranging from 5 to 20 minutes (mean 11.2± 5.7 minutes).The mean WOMAC score has been 46.29±13.03. The prominent locations of pain in the left knee have been patella (25%) also the main sites at the right knee have been patella (41%). Intense regular duties have been the most challenging task, with an average of 3.26±0.85 (severe to extreme 3-4).
Conclusions: Majority of patients with knee OA had moderate level of knee pain and functional disability in daily living and they had the ability to localize site of pain. Also, the severity of knee pain and stiffness may influence the degree of disability in OA patients. As a result, OA treatments can be based on clinical aspects and functional status rather than relying on radiological findings.
