In recent years, the medial patellofemoral ligament (MPFL) has been considered as the primary restraint of the medial patellar stabilizers [1]. Clinical reports have revealed that MPFL injury occurs in almost all patients with traumatic patellar dislocation, and attention has been focused on the repair and reconstruction of the MPFL in recurrent patellar dislocation and patellar subluxation [2]...

Articular cartilage injuries to the patella are frequent after patellar dislocation. The management of these acute cartilage injuries in the acute setting can be challenging. It is well documented that acute fixation is the optimal choice for treatment of osteochondral injuries. This article discusses the challenges and potential treatment options for acute chondral/osteochondral injuries to th...

Primary patellar dislocation injures the medial patellofemoral ligament (MPFL), the major soft-tissue stabilizer of the patella, which may lead to recurrent patellar instability. Recurrent patellar dislocation are common and may require surgical intervention. The variation in location of injury of the MPFL and the presence of an osteochondral fracture produces challenges in clinical decision ma...

BACKGROUND Numerous studies have investigated the influence of osseous factors on patellofemoral joint instability, but research on the influence of dynamic muscle factors in vivo is still in the exploratory stage. This study aimed to use magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) to evaluate vastus medialis oblique (VMO) fiber bundles in patients with recurrent patella...

Purpose Patellofemoral instability is a common cause of anterior knee pain in adolescents and young adults. Most normal and pathological values for diagnosing patellofemoral instability are based on Western literature. We conducted this radiological study to determine normal values for different patellofemoral parameters in a Korean population and to evaluate their usefulness in diagnosis. Ma...

UNLABELLED Recently, medial patellofemoral ligament reconstruction has been emphasized for the treatment of patellar dislocation. This study compared the results of medial patellofemoral ligament reconstruction by adductor magnus tenodesis with distal patellar realignment in patients with recurrent patellar dislocation. Additionally, the development of patellofemoral osteoarthrosis was compared...

CONTEXT The rising popularity and intensity of youth sports has increased the incidence of patellar dislocation. These sports-related injuries may be associated with significant morbidity in the pediatric population. Treatment requires understanding and attention to the unique challenges in the skeletally immature patient. EVIDENCE ACQUISITION PubMed searches spanning 1970-2013. STUDY DESIG...

BACKGROUND The present study aimed to describe a new safe and economical technique for medial patellofemoral ligament (MPFL) reconstruction with satisfactory clinical outcomes, and present the results of a four-year follow-up. MATERIAL AND METHODS Thirty-two patients with recurrent patella dislocation, who underwent MPFL reconstruction with two semi-patellar tunnels and hardware-free patellar f...

The objective of this study was to explore the clinical effect of medial and lateral retinaculum plasty for congenital patellar dislocation due to small patella syndrome. Twelve patients with congenital patellar dislocation due to small patella syndrome treated at the authors' hospital between January 2005 and February 2010 were enrolled in the study. The study group comprised 4 men (4 knees) a...
