All-Arthroscopic Implantation of Minced Juvenile Chondral Allograft for an Isolated, Full-Thickness Chondral Lesion in the Trochlea of an Adult Knee.

Current use of juvenile chondral allograft (DeNovo; Zimmer, Warsaw, IN) within the knee is an emerging treatment option for full-thickness, isolated chondral lesions. Its implantation traditionally involves a formal arthrotomy for exposure. Arthroscopic implantation minimizes the morbidity associated with this treatment option yet retains the promising functional results already established in the literature. We present a technique for all-arthroscopic implantation of juvenile chondral allograft (DeNovo) for a symptomatic, isolated chondral lesion within the trochlea of an adult knee.
