Outcome After Soft Tissue Realignment of the Tibial Insertion of the Patella Tendon

2014-07-24 14:10:09 | BioPortfolio


Soft tissue realignment of the tibial insertion of the patella tendon is a simple operative technique for treating dislocation of the patella in childhood and adolescence. It is performed in children with either recurrent dislocation or complicated primary dislocation in cases with malalignment or maltracking of the patella and a lateralised tibial tuberosity. It can be performed in patients with open epiphyses. We investigate long-term outcome after this procedure.


Method. Investigation of the outcome of a relatively new method for centralisation of the insertion of the patella tendon in patients with open epiphyses. Using a soft tissue technique the patella tendon is released from the tibial tuberosity with the tendon still fixed to the distal periosteum. The tibial periosteum is split on the lateral border of the tibia distally. Together with lateral release this procedure releases the patella tendon which finds a new insertion more medially. Because the tendon is still fixed at the distal periosteum no additional fixation is needed and therefore no complications occur at the tibial apophysis due to osteosynthetic material. Full weight bearing is possible after 4 weeks and movement is not restricted.Results. From 1999 to 2004 a total of about 90 operations in about 80 patients for soft tissue centralisation of the distal insertion of the patella tendon were carried out on children and adolescents aged between 10 and 18 years old. This study is a retrospective analysis of the outcome after 6 to 10 years. Relevant outcome criteria will be evaluated with the occurrence of recurring dislocation, the Lysholm score, the Tegner activity scale and subjective measurement with the VAS scale and an additional functional outcome score, that we created especially for children. Eventual occurrence of growth disturbance or osteoarthritis will be documented be clinical or radiological features.

Medical and Biotech [MESH] Definitions

A band of fibrous tissue that attaches the apex of the PATELLA to the lower part of the tubercle of the TIBIA. The ligament is actually the caudal continuation of the common tendon of the QUADRICEPS FEMORIS. The patella is embedded in that tendon. As such, the patellar ligament can be thought of as connecting the quadriceps femoris tendon to the tibia, and therefore it is sometimes called the patellar tendon.

Displacement of the PATELLA from the femoral groove.

A syndrome of multiple abnormalities characterized by the absence or hypoplasia of the PATELLA and congenital nail dystrophy. It is a genetically determined autosomal dominant trait.

Surgical procedure by which a tendon is incised at its insertion and placed at an anatomical site distant from the original insertion. The tendon remains attached at the point of origin and takes over the function of a muscle inactivated by trauma or disease.

Nodular bones which lie within a tendon and slide over another bony surface. The kneecap (see PATELLA) is a sesamoid bone.
