Injuries in the articular cartilage of the knee are frequent in young and active people. It is a common finding during knee arthroscopic surgery, with a reported prevalence of up to two third of the cases. Regarding only localized cartilage defects, they can be seen in around 20% of patients.

Introduction

Injuries in the articular cartilage of the knee are frequent in young and active people [1]. It is a common finding during knee arthroscopic surgery, with a reported prevalence of up to two third of the cases. Regarding only localized cartilage defects, they can be seen in around 20% of patients [2]. In these young group of people, knee arthroplasties show low satisfaction rates and high failure rates due to accelerated loosening or wear [3, 4].

Multiple surgical options have been developed for localized articular cartilage defects, including autologous chondrocyte implantation, subchondral marrow stimulation, osteochondral autograft transplantation, and fresh osteochondral allograft (FOCA) transplantation. FOCA is an effective biologic, durable treatment option for localized femoral, patellar or tibial osteochondral defects [5]. It is performed in a single-stage technique and may be preferable to other surgical alternatives, particularly in the setting of unshouldered lesions, extensive subchondral edema, or extensive bone loss that requires restoration.

One of the main advantages of using FOCAs is the presence of metabolically active chondrocytes without concurrent donor site morbidity [6]. Most soft tissue and bone allografts can be easily storage in tissue...
