Today, the treatment of patellar luxations using current techniques has become a very common procedureas part of the surgical treatment. Nevertheless, there are some doubts about such procedures in restraining the patella in lower grade cases. The purpose of the present retrospective clinical study was to determine theefficacy of the soft tissue and bone reconstructive procedures used for vario...

Originally the main idea was to obtain a stable patella, i.e., to stabilize the "slipping patella". In the past many conditions like patella alta, ligamentous laxity, PF bone hypoplasia, weakness of the quadriceps muscle, genu valgum or genu recurvatum were thought to predispose to patellar instability. For a long period muscle exercises were instituted to strengthen the weak m.vastus medialis ...

In this case report, the surgical treatment of a calf with congenital, unilateral lateral patellar luxation clinical, radiography, and computed tomography findings is presented. A 5-day-old was referred due to an extremely flexed knee joint hindlimb weakness. Radiographic, tomographic, orthopedic examination demonstrated grade 3 normal stifle bone anatomy. Surgery includes release medial imbric...

INTRODUCTION Cartilage lesion with patellar malalignment may be correlated with pain. Situations in which patients with recurrent patellar dislocation are painless between episodes of luxation can be approached with considerable curiosity. We evaluated the distribution of substance-P and S-100 protein expression in soft tissue of the knee in children with recurrent patellar dislocation, in orde...

Patella luxations occur frequently in dogs (primarily medial (MPL) [1]) and less commonly in cats [2]. It is normally seen in small breed dogs but is becoming more common in dogs such as the Labrador retriever. It can be unilateral or bilateral (50-65%) of cases. Both conservative and surgical methods are used for correction of patella luxation and this decision-making usually depends on the se...

The need to characterize and understand the contribution of femoral and tibial bone deformity associated with medial patellar luxation was recognized by Putnam and Singleton fifty years ago (1, 2). For a very long time we struggled to comprehend this problem because the only means to image these bones non-invasively was radiology. Two-dimensional radiographic images were subject to projection a...

OBJECTIVE To measure the quadriceps angle (Q-angle) in dogs with congenital patellar luxation using magnetic resonance (MR) methods. STUDY DESIGN Prospective clinical study. ANIMALS Thirty-eight client-owned dogs. METHODS Thirty-eight dogs were examined and placed into the following groups based on the degree of patellar instability: normal, grade I, grade II, and grade III. MR images of ...
