Effects of simulated vastus medialis strength variation on patellofemoral joint biomechanics in human cadaver knees.
Selective strengthening of the vastus medialis (VM) muscle is a conservative treatment used to address some patellofemoral joint (PFJ) problems. The objective of this study was to examine the effects of varying VM strength on PFJ kinematics and contact pressures and areas. We tested five fresh-frozen cadaveric knees using a custom knee jig, which permits the simulation of physiologic quadriceps...
متن کاملPatellar tilt correlates with vastus lateralis: vastus medialis activation ratio in maltracking patellofemoral pain patients.
Patellofemoral (PF) pain is a common ailment of the lower extremity. A theorized cause for pain is patellar maltracking due to vasti muscle activation imbalance, represented as large vastus lateralis:vastus medialis (VL:VM) activation ratios. However, evidence relating vasti muscle activation imbalance to patellar maltracking is limited. The purpose of this study was to investigate the relation...
متن کاملThe influence of orthotic devices and vastus medialis strength and timing on patellofemoral loads during running.
OBJECTIVE To use a musculoskeletal model and simulation of running to examine: (1) the influence of two commonly prescribed treatments for patellofemoral pain (vastus medialis oblique strengthening and orthoses) and (2) the functional significance of timing differences between vastus medialis oblique and vastus lateralis on lateral patellofemoral joint loads. DESIGN A three-dimensional muscul...
متن کاملThe Effect of High Heel Shoes on Tibiofemoral and Patellofemoral joint Contact Forces and Muscle Forces
Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking. Materials & Methods: A tot...
متن کاملContact pressure at osteochondral donor sites in the patellofemoral joint.
BACKGROUND The lowest contact pressure point is presumed to be the best site to harvest an osteochondral plug and minimize morbidity. HYPOTHESIS Patellofemoral contact pressures are not uniform and are lowest along the medial patellofemoral articulation. STUDY DESIGN Controlled laboratory study. METHODS Seven cadaveric knees were tested with an electroresistive, dynamic pressure sensor pl...
