The ideal goal of treatment for osteochondral lesions is to resurface the lesions with hyaline cartilage and to prevent the occurrence of secondary osteoarthritis. To achieve this goal, autologous chondrocyte implantations (ACI) have been developed and clinically applied to osteochondral lesions of the knee and ankle joints. 2 , 3 , 7 , 20 , 25 , 26 , 33 Osteochondral lesions such as osteochondral dissecans (OCD) or osteochondral fractures are frequently involved in the elbow. Although the implementation of ACI in the elbow has been reported, 17 , 28 postoperative follow-up is limited. Consequently, the surgical efficacy of this procedure remains unclear. We present 2 patients with OCD in the elbow who underwent ACI, with favorable clinical and radiographic outcomes over a 4-year follow-up.
