Traditionally, conservative management of patellofemoral pain syndrome (PFPS) involved pain-relieving techniques and standard quadriceps strengthening in non-weight bearing positions. In 1986, an Australian physiotherapist, Jenny McConnell, proposed an innovative management program based on the premise that abnormal patellar tracking plays a key role in the etiology of PFPS.63Passive, active, and neural factors predisposing to abnormal patellar tracking were to be identified via a thorough assessment of the patient. Based on the assessment findings, the treatment program aimed first to unload abnormally stressed soft tissue around the patellofemoral joint by optimizing the patellar position and second, to improve the lower limb mechanics. The program included vastus medialis obliquus (VMO) retraining in functional weight-bearing positions combined with patellar taping, patellar mobilization, correction of foot and lower limb mechanics, and stretching to reduce pain and enhance VMO activation. This chapter will focus on the McConnell program for conservatively managing PFPS. It will describe factors predisposing to PFPS as a theoretical rationale for the program and include details of assessment and treatment.
