Rearfoot Posture in Subjects With Patellofemoral Pain

Abstract

Robert Maffucci, MPT 2r4Sean Hampton, MPT 3t4 atellofemoral pain is one 1 of the most commonly encountered disorders involving the knee (8,20), comprising approximately 25% of all diagnoses (3). While patellofemoral-related problems occur twice as often in females compared with males, men outnumber women when athletes are studied (18).Abnormal patellar tracking, such that transient medial or lateral displacement occurs during flexion and extension, has been documented as a cause of articular cartilage damage and pain (1 1,16). In general, subluxation involves excessive lateral displacement of the patella, which typically occurs between 10 to 20" of flexion (9). The natural tendency of the patella to track laterally has been described by Fulkerson and Hungerford (9) as the "law of valgus." This is a result of the valgus orientation of the lower extremity, where the relationship of the anterior superior iliac spine of the pelvis to the midline at ground contact forms a 10" angle between the femur and the tibia. Since the quadriceps follow the longitudinal axis of the femur, this angle has been described as the quadriceps or Q angle. This structural orientation predisposes the patella to lateral tracking forces with quadriceps tension (15).Skeletal malalignments have been shown to have a profound effect on the magnitude of the Q angle and the subsequent laterally directed (.87 and .86, respectively

The Relationship between Activity of Abductor Hallucis and Navicular Drop in the One-leg Standing Position

“…However, excessive pronation (pes planus) is a chronic condition caused by insufficient support of the medial longitudinal arch (MLA) of the foot [3][4][5] . An excessively pronated foot is associated with several clinical pathologies of the lower extremity, including plantar fasciitis, tibialis posterior tendinitis, Achilles bursitis or tendinitis, and patellofemoral pain syndrome [6][7][8][9] .…”

“…This syndrome is present in approximately 25% of orthopedic diagnoses 4 and is defined as a pain at the front of the knee and/or rear of the patella [4][5][6] . It is aggravated during physical activities and when going up and down stairs, walking on slopes, squatting and remaining seated for long periods of time 7 .…”

Bilateral Rearfoot Asymmetry and Anterior Knee Pain Syndrome

“…While some 11,32,36 have provided evidence to support a positive relationship between rearfoot posture and knee pathologies, others have not. 27,42,45 These enigmatic results may be explained in part by the differing data collection and analysis methods utilized.…”
