Hybrid Medial Patellofemoral Ligament Reconstruction Using the Semitendinous Tendon for Recurrent Patellar Dislocation: Minimum 3 Years’ Follow-up

Patellar instability

“…Nomura et al followed 12 patients after MPFL reconstruction for an average of 4.2 years. An 83% of patients were classified as excellent or good and there were no cases of patellar instability following surgery 41 . Authors found fair results only among patients with pre-existing chondromalacia of the patella 41 .…”

Panagopoulos et al followed 25 patients after MPFL reconstruction for an average release may be used as an adjunct to proximal or distal realignment procedures 38 .…”

Modern management of patellar instability

“…Reconstructions using various different soft tissue harvest grafts have been documented, including semitendinosus [64][65][66][67], gracilis [68,69], quadriceps tendon [70], adductor magnus [71][72][73] and even a mesh-type artificial ligament [74,75]. The femoral attachment can be secured through a variety of different methods, including a bone block on the graft, screw and washer, or EndoButton™ fixation.…”

Avaliação tomográfica dinâmica pré e pós-reconstrução do ligamento patelofemoral medial de pacientes com instabilidade patelar recidivante

“…Apesar da grande variação de técnicas descritas para sua reconstrução, se acumulam evidências que mostram bons resultados clínicos dessa cirurgia [4][5][6][7][8][9]72,84 . Além dos estudos clínicos, outros trabalhos biomecânicos sugerem que o reparo ou reconstrução do LPFM restaura a fisiologia PF 15,45 .…”

“…Apesar dessa importância biomecânica, o conhecimento da reconstrução do LPFM é relativamente recente, tendo ocorrido principalmente nas últimas duas décadas, com a descrição de muitas técnicas, com diferentes fontes de enxerto e métodos de fixação. Mesmo com toda essa variedade, se acumulam evidências que mostram bons resultados clínicos dessa cirurgia [4][5][6][7][8][9] , com taxa muito baixa de recidiva da instabilidade.…”
