Dysfunction of the knee extensor mechanism resulting in patellofemoral pain (PFP) presents a significant challenge to those clinicians working in musculoskeletal medicine. The presence of the condition is believed to be related to changes in internal joint loading as a result of alteration in the position and tracking of the patellofemoral joint. One of the first challenges when assessing and treating this condition faced by the clinician is how to reliably and validly assess patella position. Papers presented within this thesis have established a reliable and valid method of achieving this. Repositioning of the patella through external means such as taping or internal means through facilitation of muscle contraction of the principle stabiliser of the patella; vastus medialis oblique (VMO) have been proposed as treatment of this condition. Papers presented within this thesis have established that patella taping significantly reduces pain, improves quadriceps function but does not facilitate the action of VMO or change patella position. Further work has established that taping's mode of action is likely to be related to changing internal joint loading. Many authors have suggested various means to facilitate the contraction of VMO; papers presented within the thesis suggest that it is not possible to facilitate an improvement in the contraction status of VMO in isolation from the rest of the quadriceps. A number of the papers presented have detailed either improvement in the current modes of assessment in order to make them valid and reliable or offer unique methods of assessment which may negate the need for invasive, expensive or time consuming means of assessments. The condition of PFP is one frequently cited as difficult to treat with poor long term outcomes. From the works presented possible explanations could be hypothesised as to why the current conventional conservative management may have failed to produce positive outcomes in some patients.
