  • thigh
  • All participants underwent two phases of data collection: 1) magnetic resonance imaging of the knee, patellofemoral joint, and thigh, and 2) kinematic, kinetic and EMG analysis during walking, running, stair ascent, and stair descent. (ebscohost.com)
  • radiographs
  • One possible reason for this is the fact that this secondary ridge is often purely cartilaginous ( Fig. 1.5 ) and, not always being reflected in subchondral bone, may not be apparent on tangential radiographs of the patellofemoral joint (Fig. 1.6, A and B ). There is considerable individual variation in the prominence of the secondary ridge. (patellofemoral.org)
  • bone
  • Frequently such individuals have severe disability in their 50s and can be helped by patellofemoral replacement which removes very little bone and is therefore much preferred to a total knee replacement. (allevyngentle.com)
  • J Bone Joint Surg Am. 90: 2751-62. (wikipedia.org)
  • Cartilage is a thin, elastic tissue that protects the bone and makes certain that the joint surfaces can slide easily over each other. (wikipedia.org)
  • Forces
  • The purpose of this study was to describe an imaging based, subject specific model that was developed to quantify patellofemoral joint reaction forces (PFJRF's). (ebscohost.com)
  • Normalization of Ground Reaction Forces, Joint Moments, and Free Moments in Human Locomotion. (ebscohost.com)
  • When using joint models to estimate tissue specific stresses, the decision of which technique is used to estimate muscle forces plays a significant role in determining the magnitude of estimated stresses in patellofemoral joint models. (physiospot.com)
  • cartilage
  • This study showed the potential of using an Alicona Infinite focus G5 optical profiler to assess the change in cartilage topography in natural joints. (bl.uk)
  • Anteriorly, the synovial membrane is attached on the margin of the cartilage both on the femur and the tibia, but on the femur, the suprapatellar bursa or recess extends the joint space proximally. (wikipedia.org)
  • There are two types of joint cartilage in the knees: fibrous cartilage (the meniscus) and hyaline cartilage. (wikipedia.org)
  • Hyaline cartilage covers the surface along which the joints move. (wikipedia.org)
  • Cartilage is a resilient and smooth elastic tissue, rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components. (wikipedia.org)
  • Over the last years, surgeons and scientists have elaborated a series of cartilage repair procedures that help to postpone the need for joint replacement. (wikipedia.org)
  • symptoms
  • Strategies that address the modifiable factors for risk of PFJ OA may aid in alleviating joint loads and symptoms for people after ACLR. (bmj.com)
  • femur
  • The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement. (wikipedia.org)
  • patients
  • Such reports raise the possibility that aggressive early treatment of certain patients (those with more severe malalignment and joint damage) may improve long‑term results. (patellofemoral.org)
  • exercises
  • Changes in activity patterns such as excessive increases in running mileage, repetitions such as running up steps and the addition of strength exercises that affect the patellofemoral joint are commonly associated with symptom onset. (wikipedia.org)
  • presence
  • also termed crepitation) is a medical term to describe the grating, crackling or popping sounds and sensations experienced under the skin and joints or a crackling sensation due to the presence of air in the subcutaneous tissue. (wikipedia.org)
  • usually
  • Authors who report ground reaction force (GRF), free moment (FM), and resultant joint moments usually normalize these variables by division normalization. (ebscohost.com)
  • model
  • A characterization study was carried out to investigate the suitable animal model required to simulate a human joint that requires osteochondral substitutions. (bl.uk)
  • Motion capture and force platform data were processed using both solely inverse dynamics and inverse dynamics with static optimization to estimate the quadriceps force in a patellofemoral joint model. (physiospot.com)
  • femoral
  • Additionally, a line drawn through the femoral neck superimposed on a line drawn through the femoral condyles forms an angle, the torsion angle, which makes it possible for flexion movements of the hip joint to be transposed into rotary movements of the femoral head. (wikipedia.org)
  • femur
  • The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement. (wikipedia.org)
  • It originates on the femur 1 cm distal to the sMCL origin and inserts 3-4 mm distal to the joint line. (wikipedia.org)
  • Notable exceptions to palpation are the hip joint, and the neck and body, or shaft of the femur. (wikipedia.org)
  • This line stretches from the hip joint (or more precisely the head of the femur), through the knee joint (the intercondylar eminence of the tibia), and down to the center of the ankle (the ankle mortise, the fork-like grip between the medial and lateral malleoli). (wikipedia.org)
  • often
  • It is treated by arthroplasty, the replacement of the joint by a synthetic joint often made of a stainless steel alloy (cobalt chromoly) and ultra high molecular weight polyethylene (UHMWPE). (wikipedia.org)
  • lateral
  • Divergence from the normal femorotibial angle is called genu varum if the center of the knee joint is lateral to the mechanical axis (intermalleolar distance exceeds 3 cm), and genu valgum if it is medial to the mechanical axis (intercondylar distance exceeds 5 cm). (wikipedia.org)
  • cartilage
  • Cartilage is a resilient and smooth elastic tissue, rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components. (wikipedia.org)
  • Over the last years, surgeons and scientists have elaborated a series of cartilage repair procedures that help to postpone the need for joint replacement. (wikipedia.org)
  • functional
  • Movement assessment is the practice of analysing movement performance during functional tasks to determine the kinematics of individual joints and their effect on the kinetic chain. (wikipedia.org)
  • musculoskeletal
  • Musculoskeletal evaluation testing is taught one joint at a time, one muscle test at a time, so "isolated movement" bias continues to be reinforced. (wordpress.com)
  • Bone
  • The way it was taught when I was in school was body region by body region, origin, insertion (of muscle on bone) and action (independently, or in concert to affect 1 or 2 joints). (wordpress.com)
  • J Bone Joint Surg Am. 90: 2751-62. (wikipedia.org)
  • usually
  • Usually, the large joints of the lower limb are aligned in a straight line, which represents the mechanical longitudinal axis of the leg, the Mikulicz line. (wikipedia.org)
  • bones
  • The three bones that make up the elbow joint are the humerus (upper arm,) and the two bones of the forearm, the radius and ulna. (twinboro.com)
  • manual
  • Manual therapy is used to "correct" an SI joint alignment, with no attention given to hip mobility or pillar stability as part of a home program. (wordpress.com)
