Prolonged dislocation of the patella is a rare condition and is often related to severe osteoarthritis (OA) of the femorotibial (FT) joint. For this condition's treatment, numerous surgical techniques using total knee arthroplasty (TKA) have been published. To the best of our knowledge, this case report is the first description of the use of lateral release alone to treat recurrent patellar sub...

during an eight month prospective study, 8240 newborns were examined for detection of congenital dislocation of the hip from oct. 23, 1991 to june 22, 1992. on first examination we found 1302 neonates (158/1000 live births) to have abnormal hips 1063 (81.6%) were prone to subluxation (subluxatable), 218 (16.81 %) prone to dislocation (dislocatable), 17 (1.3%) were dislocated and 4 (0.3%) were t...

The patella is a motorical important part of the feline stifle joint. By gliding proximally and distally inside trochlear groove, its position continually changes during each step mobility. Stifle diseases like patellar luxation, cruciate ligament rupture, or tendon disease as well consecutive surgical interventions may cause dislocation.

Background: There are a number of different factors that are thought to play a role in patellar instability, including injuries to the medial patellofemoral ligament (MPFL), trochlear dysplasia, patella alta, and an increased tibial tuberosity-trochlear groove (TT-TG) distance. Objective: To use MRI to assess injury patterns to the MPFL, trochlear dysplasia, patellar height, and TT-TG distance ...
