The ‘pain’ is lacking from the research on patellofemoral pain 

An interesting observation from recent International Patellofemoral Pain Retreats (IPFR) is the relatively low proportion of submitted abstracts focusing on pain sciences (ie, 6% (3/50; Manchester, UK, 2015)1 and 29% (15/52; Gold Coast, Australia). Coupled with a recent IPFR consensus document strongly linking biomechanical factors to elevated patellofemoral joint load and pain, we are left questioning where our contemporary understanding of pain fits?

Patellofemoral pain research is replete with studies evaluating a range of biomechanical features of the condition. For the most, these studies are disparate, with small samples. Powers et al2 deserve credit and recognition for completing the huge task of efficiently reviewing and summarising this body of work. While this framework helps make sense of a complex range of physical features, we are compelled to address an issue that will likely impede the framework’s usefulness to guide clinical pracice. When viewed in isolation, the pathomechanical framework posits that patellofemoral pain is a peripherally based nociception. This raises a point of contention, …
