Treatment of Focal Chondral Lesions in the Patellofemoral Joint with Collagen Membrane: Clinical and Functional Outcomes in a Two-Year Follow-Up
Pedro Debieux, José Ricardo Dantas Moura Costa, Wesley Araujo Weis, Diego da Costa Astur, Camila Cohen Kaleka, Moisés Cohen

TL;DR
This study shows that a collagen membrane-based surgical technique improves clinical and functional outcomes in patients with patellofemoral cartilage lesions over two years.
Contribution
The study provides clinical evidence for the effectiveness of autologous matrix-induced chondrogenesis in treating focal cartilage lesions in the patellofemoral joint.
Findings
All patient-reported outcome scores significantly improved after a minimum of two years of treatment.
The AMIC technique was found to be safe, effective, and viable for treating full-thickness cartilage defects.
Improvements were observed in pain levels and functional knee scores.
Abstract
Avaliar os desfechos clínicos e funcionais de pacientes submetidos a tratamento cirúrgico para reparo de lesão condral focal na patela e na tróclea, pela técnica de condrogênese induzida por matriz autóloga ( autologous matrix-induced chondrogenesis , AMIC, em inglês), após um mínimo de 2 anos de tratamento. Ao todo, 24 pacientes (25 joelhos) com idade média de 39,6 ± 4,7 anos foram submetidos à técnica AMIC patelofemoral e foram avaliados em um seguimento médio de 3,64 ± 0,65 anos. Os fatores dos pacientes, a morfologia da lesão e as medidas de resultado relatadas pelos pacientes, incluindo os escores do International Knee Documentation Committee (IKDC), de Tegner, de Kujala, de Fulkerson, de Lysholm, e a Escala Visual Analógica (EVA), foram coletados. O sexo masculino representou 76% da amostra. O tamanho médio do defeito das lesões condrais foi de 1,99 ± 0,36 cm 2 . Todos os…
