A common rehabilitation strategy for patellofemoral pain syndrome (PFPS), which lacks scientific evidence, includes pulling the patella medially with tape to reduce pain and increase the vastus medialis oblique (VMO) muscle activity. The purpose of this study was to examine the effect of various patellar taping procedures on force production, EMG activity of the VMO and vastus lateralis (VL) mu...

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: A potential specific problem of patellar tendon graft in ACL reconstruction is the possibility of graft-tunnel mismatch which could be more problematic with anatomic ACL reconstruction where the femoral tunnel is placed low on the lateral wall of the lateral femoral condyle. The occasional occurrence of this mismatch raises the question that whether a correlation exists between pat...

BACKGROUND The prevalence of patellar tendinopathy is elevated in elite soccer compared to less explosive sports. While the burden of training hours and load is comparably high in youth elite players (age < 23 years), little is known about the prevalence of patellar tendinopathy at this age. There is only little data available on the influence of age, the amount of training, the position on the...

BACKGROUND Patella alta and patella baja are important conditions underlying a predisposition to many joint diseases, including patellar luxation and patellar chondromalacia of the articular cartilage. The frequencies of patella alta and patella baja have not yet been determined. The objectives of this study were to determine the frequency of patella alta and to determine reference values to th...

Abstract Objective To assess the role of proximodistal and caudocranial relative position patellar ligament insertion on tibia length‐to‐patellar length ratio (PLL:PL) in small‐breed dogs with without grade II medial luxation (MPL). Study Design Retrospective study. Sample Population Dogs weighing ≤15 kg, including 43 stifles MPL 34 control stifles. Methods The was determined as a using vertica...

Background: Bilateral rupture of the patellar tendon is a very rare injury, which takes place in relation to chronic systemic diseases. These injuries are known causes. Some of these causes are particular in patellar tendon rupture and another are in quadriceps tendon rupture. Case presentation: 70-year-old diabetic man with simultaneous bilateral patellar tendon disruption of proximal inser...

Medial patellar luxation is defined as medial displacement of the patella from the trochlear groove. In dogs, medial luxations account for 75% of all patellar luxation cases, and are frequently associated with patella alta. Common surgical treatments for medial luxation are trochleoplasty and lateral transposition of the crest to drive the patella into the correct anatomical alignment. Postoper...

PURPOSE To assess normal patellar tracking during walking using the 9-camera infrared system. METHODS Four men and 6 women aged 25 to 33 (mean, 29) years each performed 16 walking trials on one occasion. They had prominent patellae with minimal soft tissues (minimising skin artefacts), and their knees and lower limbs were normal and symmetrical. 12 retro-reflective markers (2.5 cm in diameter...

BACKGROUND Patellar stabilizing braces are used to alleviate pain and prevent subluxation/dislocation by having biomechanical effects in terms of improved patellar tracking. The purpose of this study is to analyze the effects of the dynamic patellar realignment brace, Patella Pro (Otto Bock GmbH, Duderstadt, Germany), on disease determinants in subjects with patellofemoral instability using upr...
