Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| American Orthopaedic Foot & Ankle Society(AOFAS) ankle-hindfoot score | 4 years | American Orthopaedic Foot & Ankle Society(AOFAS) ankle-hindfoot score. The higher score represent the better outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| International Cartilage Repair Society(ICRS) score | 4 years | International Cartilage Repair Society(ICRS) score. The higher score represent the better outcome. |
| Magnetic Resonance Observation of cartilage repair tissue(MOCART) score | 4 years | Magnetic Resonance Observation of cartilage repair tissue(MOCART) score. The higher score represent the better outcome. |
| Tegner activity level score | 4 years | The highest level of activity that you participated in before your injury and the highest level you are able to participate in currently. The higher values represent a better outcome. |
| Visual analogue scale | 4 years | The visual analogue scale or visual analog scale (VAS) is a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. From 0 to 10, no pain 0, worst pain imaginable 10. The higher values represent a worse outcome. |
