Objective.To determine the diagnostic test performance of location of pain and activity-related pain in identifying knees with patellofemoral joint (PFJ) structural damage.Methods.The Multicenter Osteoarthritis Study is a US National Institutes of Health-funded cohort study of older adults with or at risk of knee osteoarthritis. Subjects identified painful areas around the knee on a knee pain map and the Western Ontario and McMaster Universities Osteoarthritis Index was used to assess pain with stairs and walking on level ground. Cartilage damage and bone marrow lesions were assessed from knee magnetic resonance imaging. We determined the sensitivity, specificity, positive and negative predictive values for presence of anterior knee pain (AKP), pain with stairs, absence of pain while walking on level ground, and combinations of tests in discriminating knees with isolated PFJ structural damage from those with isolated tibiofemoral joint (TFJ) or no structural damage. Knees with mixed PFJ/TFJ damage were removed from our analyses because of the inability to determine which compartment was causing pain.Results.There were 407 knees that met our inclusion criteria. “Any” AKP had a sensitivity of 60% and specificity of 53%; and if AKP was the only area of pain, the sensitivity dropped to 27% but specificity rose to 81%. Absence of moderate pain with walking on level ground had the greatest sensitivity (93%) but poor specificity (13%). The combination of “isolated” AKP and moderate pain with stairs had poor sensitivity (9%) but the greatest specificity (97%) of strategies tested.Conclusion.Commonly used questions purported to identify knees with PFJ structural damage do not identify this condition with great accuracy.

Patients with a patellofemoral pain are either in an acute state after a patellofemoral dislocation or are suffering from a chronic anterior knee pain (AKP), whereas AKP might be accompanied by patellar instability without dislocation. Whereas the acute state after a dislocation is mostly clear and its examination limited, the examination of a AKP is much more complex. A profound knowledge of the anatomy, the painful structures and patellofemoral biomechanics is essential in order to find the underlying pathology within the heterogeneous and diverse etiologies. Furthermore, a meticulous and precise examination is key to find the adequate treatment for AKP.

Anterior Knee

Up to 40% of all athletes suffer from patellofemoral disorders every season, with a high prevalence of 15-25% especially in pivoting sports [1]. It has a high risk of recurrence, might persist for a prolonged time and therefore considerably influence the athlete’s trainability and performance over his career. Exercise-related, peripatellar pain is the most frequent observed condition and usually described as anterior knee pain (AKP), or synonymously called patellofemoral pain syndrome (PFPS). The formerly used term “chondromalacia patellae” has been shown to be misleading, and is no longer used in literature...

Saudi Patients

Radiographic osteoarthritis of the knee is very common in Saudi patients, especially in the patellofemoral compartment. Some studies have considered repetitive daily prayer activities as a factor of causation. However prevention and management recommendations appear to be non-existent in the literature. This report describes the case of chronic bilateral anterior knee pain in a devout adult male, which was dramatically alleviated by simply using a padded cushion under the prayer rug. Simple strategies of temporarily modifying prayer posture, insuring good prayer form, and adequate knee padding, may offer promise as low tech and economical solution for the management of anterior knee pain in this cultural group.
