Bipolar Fresh Osteochondral Allograft Transplantation and Joint Reconstruction for Patellar and Trochlear Cartilage Defects

Abstract: Patellar instability is a debilitating condition, and trauma due to the dislocations may severely damage the articular cartilage of the patellofemoral joint. The lack of healing capacity of cartilage makes treatment of such lesions challenging. In young patients, preservation of native bone and cartilage is a priority, and therefore arthroplasty procedures should be avoided even in relatively larger lesions. Fresh osteochondral allografting has been described for these difficult and complex cases, with recent … Show more

“…En la actualidad, se describen dos técnicas principales para el injerto osteocondral fresco basadas en el tamaño de la lesión condral: la técnica clavija o press-fit, para lesiones pequeñas (<5 cm 2 ) y lesiones medianas (5-10 cm 2 ), y la de bloque óseo, para lesiones grandes (>10 cm 2 ) o que comprometen más del 75% de la superficie articular. 4,5,[13][14][15] Esta última técnica fue la que se empleó en nuestras pacientes, pues tenían lesiones osteocondrales que comprometían más del 75% de la superficie articular. Por ello, es necesario conocer el tamaño y localización de la lesión condral, porque de ello dependerán la planificación quirúrgica y el método de fijación del injerto a partir de anclajes o tornillos de autocompresión de cabeza ocultable (Figura 13).…”
