We retrospectively reviewed the operative treatment carried out between 1988 and 1994 of eight patients with habitual patellar dislocation. In four the condition was bilateral. All patients had recurrent dislocation with severe functional disability. The surgical technique involved distal advancement of the patella by complete mobilisation of the patellar tendon, lateral release and advancement...

BACKGROUND Cranial cruciate ligament insufficiency is a common orthopaedic problem in canine patients. This cadaveric and radiographic study was performed with the aim of determining the effect of proximal translation of the tibial tuberosity during tibial tuberosity advancement (TTA) on patellar position (PP) and patellar ligament angle (PLA). RESULTS Disarticulated left hind limb specimens ...

Patellofemoral disorders represent 20–40% of all knee problems and can be one of the most common complaints in sports related injuries. These disorders are a major cause of disability, particularly in females, and in extreme cases may contribute to termination of athlete’s career and could lead to degenerative arthritic changes of the knee joint. For these reasons, disorders and in particular p...

Background: Patellar instability is a common cause of anterior knee pain and can limit function sports participation. To help assess patellar instability, the clinical J-sign test consists observing patella translate laterally in shape an inverted J over anterolateral femur proximal to trochlear groove during active extension. Only positive or negative categorization has typically been used wit...

objectives: patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome (pfps). patellar taping can considerably reduce such pain and disability. this study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with pfps (mean age 32.2±1.12 years) by using magnetic resonance imaging (mri). methods: thirty w...

The tibial tubercle (interchangeable with tuberosity) is the most distal anchor of the extensor mechanism and can serve as a tool in altering patellofemoral (PF) mechanics. Known collectively as distal realignment procedures, osteotomies of the tibial tubercle are a useful method to treat a variety of PF conditions by allowing coronal, axial, and sagittal plane adjustments of the patellofemoral...
