Underlying Pathology

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.

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.

<p class="abstract"><strong>Background:</strong> Diagnosis of patellofemroal pain syndrome has been challenging due to lack of clinical test with better sensitivity and specificity, axial imaging has been considered as the standard modality for evaluation. Patients with anterior knee pain because of patellofemoral pain syndrome can be sub-grouped as those with or without radiological positive parameter for patellar maltracking.  The aim of the present study was to evaluate reliability of clinical tests in two subgroups of patients presenting with patellofemoral pain syndrome<span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> 45 knees with anterior knee pain without any episode of patellar instability were evaluated clinically using four standard tests (patellar apprehension test (PAT), eccentric step test (EST), active instability test (AIT) and Waldron’s test. On the basis of CT scan finding (at least one positive radiological parameter of instability) 28 knees were categorized in Group A (potential patellar instability group) and 17 knees in Group B (PFPS).<strong></strong></p><p class="abstract"><strong>Results:</strong> All patients with 3 or more than three clinical test positive were cases with potential patellofemroal instability except two. Whereas other true patellofemroal pain patients all except 2 were have less than 3 positive clinical tests<span lang="EN-IN">. </span></p><p class="abstract"><strong>Conclusions:</strong> Clinical test have more diagnostic accuracy in evaluating anterior knee pain due to potential patellofemroal instability in comparison to patellofemroal pain without radiological instability<span lang="EN-IN">.</span></p>
