OBJECTIVES The aim of this study is to evaluate the usefulness of Magnetic Resonance Imaging (MRI) at 20° of knee flexion in patients with patellofemoral pain syndrome (PFPS) caused by suspected patellofemoral malalignment (PFM). MATERIAL AND METHOD Fifty MRIs were performed on 25 patients with PFPS secondary to suspected PFM based on clinical examination, and on 25 patients without PFPS (con...

The main objectives is to compare the existing full adders circuits and there performances and to design a Low Power Full Adder having improved result as compared to existing full adders. The various full adders are described namely BBL-PT (branch based logic and pass transistor logic based), conventional CMOS full adder and hybrid full adder. Finally comparisons between the various full adders...

BACKGROUND Radiographic landmarks for medial knee attachment sites during anatomic repairs or reconstructions are unknown. If identified, they could assist in the preoperative evaluation of structure location and allow for postoperative assessment of reconstruction tunnel placement. METHODS Radiopaque markers were implanted into the femoral and tibial attachments of the superficial medial col...

  Background : Biomechanical factors are known to be important in knee osteoarthritis (OA) development and progression. This study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group.   Methods: 16 females (10 with mild and 6 with moderate medial knee osteoart...

To evaluate the development of postoperative patellofemoral osteoarthritis, we performed a retrospective clinical and radiographic study of 100 patients who had undergone anterior cruciate ligament reconstruction with a bone-patellar tendon-bone autograft an average of 7 years before the follow-up. Radiographic evaluation showed no patellofemoral osteoarthritis in 53 patients (group I), mild os...

Objective: To prospectively determine gait related risk factors for patellofemoral pain. Design: A prospective cohort study. Setting: Male and female recruits of the Belgian Royal Military Academy during a 6 week basic military training period. Participants: 84 officer cadets (65 men, 19 women), who entered the Military Academy and were without a history of any knee or lower leg complaints part...

Patellar maltracking is thought to be one source of patellofemoral pain. Measurements of patellar tracking are frequently obtained during non-weight-bearing knee extension; however, pain typically arises during highly loaded activities, such as squatting, stair climbing, and running. It is unclear whether patellofemoral joint kinematics during lightly loaded tasks replicate patellofemoral joint...

We retrospectively analysed the MR scans of 25 patients with patellofemoral dysplasia and ten control subjects, to assess whether there was any change in the morphology of the patella along its vertical length. Ratios were calculated comparing the size of the cartilaginous and subchondral osseous surfaces of the lateral and medial facets. We also classified the morphology using the scoring syst...
