Background: Patellofemoral joint disorders are the most common cause of anterior knee pain in patients who referred to orthopedic clinics. Patellar lateralization cause anterior knee pain due to weakness of vastus medialis oblique muscle or tightness of lateral structures like lateral retinaculum or iliotibial band muscle. Materials and Methods: For evaluation of this abnormality, plane radiog...
Patellar resurfacing in the context of primary total knee replacement (TKR) and in the presence of patella-femoral osteoarthritis is common and widespread practice, as it reduces the rate of re-operation and anterior knee pain. There are several measuring devices and cutting jigs available in the market, which aim to aid with accurately resecting the patellar articular surface. A common charact...
To our knowledge, this is the first case of synovial osteochondromatosis in a patient presenting with a double patella-like condition. The true duplication of the patella, which is called double patella, is extremely rare. In our case, the operative and histopathological findings showed that the double patella-like condition was secondarily induced by synovial osteochondromatosis. Synovial oste...
This study was designed to investigate whether there is a difference in the strength of the bony patella following preparation either with a dome configuration or with a regular uniplanar cut in total knee arthroplasty. For each test 4 cadaveric patellae were used. Two of the 4 patellae were prepared with a regular uniplanar cut and 2 were prepared into a dome shape with a circumferential wall,...
introduction iatrogenic patellar fracture is reported as a complication of patella procedures, such as medial patellofemoral ligament reconstruction, reconstruction of the anterior cruciate ligament of the knee using bone-patellar tendon-bone technique, and resurfacing the patella in total knee arthroplasty. case presentation a 65-year-old lady with right patella fracture was treated with open ...
conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...
We present the theoretical development of the 3D multipole probability tomography applied to the electric Self-Potential (SP) method of geophysical exploration. We assume that an SP dataset can be thought of as the response of an aggregation of poles, dipoles, quadrupoles and octopoles. These physical sources are used to reconstruct, without a priori assumptions, the most probable position and ...
BACKGROUND Changing the kinematic behaviour of patellar movement could be one of the reasons for anterior knee pain after implantation of a total knee arthroplasty (TKA). The aim of the current study was to measure the potential influence on patellar kinematics of patellar resurfacing during TKA. METHODS Patellar movement before and after TKA with and without patellar resurfacing was measured...
Neglected or chronic ruptures of the patellar tendon are defined as ruptures presenting after 6 weeks. Late presentation is often due to neglect or missed diagnosis. With chronic ruptures, the patient presents with weakness, instability, and pain. Management of patients with chronic ruptures is difficult due to adhesions, proximal patellar migration, contracture, and quadriceps muscle atrophy. ...
