Objective: To report surgical technique, morphometric effects and clinical outcomes for tibial tuberosity transposition-advancement (TTTA), sulcoplasty and para-patellar fascial imbrication for management of concomitant medial patellar luxation (MPL) and cranial cruciate ligament (CCL) disease in 32 dogs. Study design: Case series. Methods: A previous technique for tibial tuberosity advancement...
A 7 yr old spayed female Chihuahua presented for right hind limb lameness and reduced stifle range of motion. Radiographs showed a marked patella baja of the right stifle and evidence of a previous surgery to correct a medial patellar luxation. A tibial tuberosity osteotomy was performed to allow proximal translation of the tibial tuberosity, which was stabilized with a tibial tuberosity advanc...
The objective of this paper is: (a) to present a rating scale for the evaluation of the musculoskeletal stress markers; (b) to analyze the medieval population from Cedynia in terms of the degree of expression and frequency of the musculoskeletal stress markers. The presented rating scale was developed based on the variability of the morphology of muscle attachment sites, observed in the skeleta...
Osgood-Schlatter disease is a condition that is caused by traction of the muscle-tendon unit at tibial tuberosity, which affects adolescents who exercise. The predisposing factors include rapid growth and physical activity, particularly running and jumping. Osgood- Schlatter disease causes intermittent pain, which can be aggravated by running, cycling and climbing stairs. We present the case of...
Biomechanical studies have shown that external rotation of the femoral TKA component improves patellar tracking but does not restore it to physiologic values. We hypothesized that this could be due to differences in the trochlear groove geometry of TKA and normal knees. This was investigated via a virtual TKA procedure that mounted femoral components on to 3-dimensional models of healthy femurs...
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...
OBJECTIVES To calculate the difference between the desired tibial tuberosity advancement (TTA) along the tibial plateau axis and the advancement truly achieved in that direction when cage size has been determined using the method of Montavon and colleagues. To measure the effect of this difference on the final patellar tendon-tibial plateau angle (PTA) in relation to the ideal 90°. METHODS Tr...
This condition usually occurs during the adolescent growth spurt before the tibial tuberosity has finished ossification. The strength of quadriceps, in children regularly practising sports that involve running and jumping, may exceed the ability of the tibial tuberosity to resist that force. As the avulsed fragments heal and grow, the tibial tubercle may enlarge. The extent will depend on the s...
