title: [Transplantation of the anterior tibial tubercle by the Elmslie-Trillat technic. Indications as a function of morphotype].
abstract: The authors note that medial transplantation of the tibial tubercle diminishes the control of lateral rotation of the tibia by the quadriceps and increases stresses on the knee in varus. They have reviewed a hundred knees operated on between 1973 and 1981. Before operation, the morphology of the patients compared with a normal population was characterised by a moderate medial torsion of the femur, a marked lateral torsion of the tibia and some genu varum. After the transplant the varus was identical but in about half of the cases, lateral laxity was noted. Passive rotation of the tibia was increased and this sign was even greater in cases of marked tibial torsion. The authors conclude that this procedure is not indicated in cases of genu varum, excessive lateral tibial torsion and lateral laxity. The best indications are cases of recurrent dislocation of the patella in knees with normal rotary alignment and painful patello-femoral syndromes. They emphasise the importance of an extensive release of the lateral patellar retinaculum, of distal transplantation of the tubercle in cases of patella alta but not too much and of some degree of anterior displacement of the tubercle.
