Introduction: Chondral lesions of the patella are a challenge for the surgeon, mainly in young and active patients. Most patellar chondral defects are superficial injuries and can be managed with joint preservation techniques; however, deep injuries may require other types of management. The objective of this article is to manage osteochondral defects of the patella in young patients, using the technique of fresh allograft from a cadaveric donor. Materials and Methods: Patients with anterior knee pain, with grade III- IV chondral lesion of the patella and who had or had not undergone some type of medical or surgical management were included. They received a fresh patellar allograft that sought to provide a solution and improvement of the functionality. Results: In all cases, recovery of functionality and mobility, absence of pain and integration of the fresh allograft into the recipient area were achieved, without evidence of tissue rejection or infection. Conclusions: The advent of fresh osteochondral grafts allows adequate management and evolution of patients, with the aim of favoring joint preservation and avoiding total knee arthroplasty over time.

Palabras clave : Patella; chondral defect; allograft; fresh; joint preservation; viability.
