Non-operative Treatment of Athletes with Anterior Knee Pain: Science, Classical, and New Ideas



Anterior knee pain (AKP) is one of the most common knee disorders in physically active individuals.29,34,95 The definition of AKP and the pathophysiological background are disputed. Despite several scientific studies through the years, the reason for AKP is still unclear. Grana and Kriegshauser maintain that the cause of AKP is multifactorial.50 Some authors mean that anatomical patella abnormalities could be causative factors (e.g., ref.48), while others mean that it is an extensor mechanism disorder, resulting in patellar malalignment during flexion and extension of the knee joint.47,52,60,118 Why this extensor mechanism disorder has developed is, however, not reported. There are also those authors maintaining that overuse is the most dominating reason for AKP, especially in youths.34,115
