Comparision of Patella Bone Stress between Individuals with and without Patellofemoral Pain
نویسندگان
چکیده
Patellofemoral pain (PFP) is the most common overuse injury of the lower extremity. It has been hypothesized that PFP is the result of increased pressure on highly innervated subchondral bone. A recent finite element (FE) modeling study has suggested that persons with PFP demonstrate elevated hydrostatic pressure and octahedral shear stress in patella articular cartilage. It is unclear however how cartilage stress influence stress within the pain-sensitive subchondral bone layer. The purpose of the current study was to test the hypothesis that females with PFP exhibit elevated patella bone stress compared to pain-free controls.

Background: Patellofemoral pain syndrome (PFPS) is defined as pain surrounding the patella when sitting with bent knees for prolonged periods of time or when performing activities like ascending or descending stairs, squatting or athletic activities. Patella dislocation is not included in PFPS. Purpose: This review analyzes the evidence based conservative management of PFPS. Methods...
متن کاملPatients with patellofemoral pain exhibit elevated bone metabolic activity at the patellofemoral joint.
Patellofemoral pain is characterized by pain behind the kneecap and is often thought to be due to high stress at the patellofemoral joint. While we cannot measure bone stress in vivo, we can visualize bone metabolic activity using (18) F NaF PET/CT, which may be related to bone stress. Our goals were to use (18) F NaF PET/CT to evaluate whether subjects with patellofemoral pain exhibit elevated...
متن کاملComparisons of bracing and patellar taping on knee three-dimensional kinematics of women with patellofemoral pain syndrome in stance phase of running
Introduction: Patellofemoral pain syndrome (PFPS) is one of the most common knee injuries that accounted for between 25-40% of all knee problems presenting to sports medicine centers. Two treatment methods of bracing and taping are recommended in these patients that their effectiveness are unclear. The aim of this study was to evaluate the efficacy of the two treatment methods on knee three-dim...
