A Review of the Role of Circulatory Deficit in the Genesis of Patellofemoral Pain

Abstract

Most physiotherapy for patellofemoral problems has a mechanical basis, consisting of lower limb exercises, stretches, taping/bracing and foot orthotics; however, in many cases physiotherapy is unhelpful. Due to the refractory nature of the condition it may be appropriate to also explore non-mechanical alternative factors, which could improve understanding and treatment of the condition. This paper provides a review of anatomy of the blood supply to the patellofemoral joint and of the roles of circulatory deficits and inflammatory processes in the production of patellofemoral pain. In addition, a simple clinical model is proposed to help practitioners categorize patellofemoral patients as hypoxic, mechanical, or inflammatory. The classification of patients in this way may improve treatment outcomes, increasing both patient and therapist satisfaction.
