Autologous osteo-periosteal cylinder graft surface is a periosteal structure, with the ability of repairment to cartilage, periosteum is closely connected to the cortical bone, then the deep loose cancellous bone.The objective of the study is to evaluate the clinical efficacy of autologous osteo-periosteal cylinder graft transplantation for Hepple V osteochondral lesions of the talus by randomized controlled trial. 70 patients with clinically diagnosed Hepple V talus osteochondral lesions according to 1: 1 were divided into experimental group and control group. The experimental group will be treated with autologous osteo-periosteal cylinder graft transplantation under arthroscopy. The control group will be treated with autologous osteochondral graft under arthroscopy. The patients will be treated by the same surgeon in this study group. Postoperative MRI MOCART evaluation, clinical AOFAS score, VAS score, Tegner score, and the secondary arthroscopy ICRS score will be selected as the measures of outcome. The incidence of adverse events will be recorded.
The trial evaluates the clinical efficacy and safety of autologous osteo-periosteal cylinder graft transplantation for Hepple V osteochondral lesions of the talus. Half of participants will receive autologous osteo-periosteal cylinder graft transplantation, while the other will receive osteochondral graft transplantation as a control group.
