Treatment of recurrent patella dislocation through arthroscopic patellar retinaculum adjustment and Fulkerson osteotomy / 中华骨科杂志

ABSTRACT

Objective To introduce the way of arthroscopic patellar retinaculum adjustment and Fulkerson osteotomy, and to study its clinical results. Methods 35 cases of recurrent patella dislocation were treated by modified Fulkerson tibial tubercle anteromedial transfer, and arthroscopic patellar retinaculum adjustment including the medial retinaculum plication and lateral retinaculum releasing. The tibial tubercle was transferred 1.5 cm anteriorly and medially, and fixed with three Kirschner wires. The patients were followed for 25 months in average. The rate of reccurence, the subjective symptoms and the function of the injured leg were evaluated according to the IKDC and Lysholm rating scale. X-ray examination was taken to evaluate the patella-femur congruence. Results There were no recurrence at the last follow-up. Anterior knee pain, though in slight degree, still existed in 8 cases. The IKDC subjective knee scores were 37.4?4.9 and 92.1?5.3(P
