Patellar Tendon-to-Patella Ratio in Children

Does Medial Patellofemoral Ligament Reconstruction Decrease Patellar Height? A Preliminary Report

“…[33][34][35][36][37] The Blackburne-Peel and Caton-Deschamps indices assess the patellar height in relation to the tibial plateau and are considered to be more reliable in children compared with the Insall-Salvati index, which is dependent on the ossification of the tibial tubercle. When used in children or adolescents, one has to account for growth and ossification pattern around the knee and their influence on these indices.…”

Vertical Patellar Position in Large‐Breed Dogs with Clinically Normal Stifles and Large‐Breed Dogs with Medial Patellar Luxation

“…In humans, patella alta has been shown to result in patellofemoral incongruity, leading to chondromalacia and substantial pain in the anterior aspect of the knee. [3][4][5][6][7] Chondromalacia may also exist in dogs with patella alta but, to our knowledge, has not yet been reported.…”

“…1,2 In human orthopedics, patella alta has been associated with recurrent patellar dislocation, subluxation, chondromalacia, and pain in the anterior aspect of the knee. [3][4][5][6][7] Limited information is available regarding potential clinical conditions associated with patella alta in the dog. It has been speculated that patella alta may play a role in canine patellar luxation.…”

Proximo-distal patellar position in three small dog breeds with medial patellar luxation

“…Patella alta, defined as proximal displacement of the patella within the femoral trochlear groove, is associated with recur-rent patellar dislocation, subluxation, chondromalacia, and pain in the anterior aspect of the knee in humans (1)(2)(3)(4). It is also associated with medial patellar luxation in large-breed dogs (5)(6)(7).…”
