Group/Cohort Label： pretherapy post-treatment
Group/Cohort Description ：The CS—ACI is used to prepare cell sheet and implant to the Cartilage defects.The arm of safety and efficacy are compared preoperative observation with postoperative observation.
Procedure: Self-control. Cells Sheet-Autologous Chondrocyte Implantation(CS-ACI) includes an arthroscopy for harvesting of cartilage 6-8 weeks prior to the open cartilage surgery. Other Names:
Cells Sheet-Autologous Chondrocyte Implantation （CS-ACI）
Other Name: Cells Sheet-Autologous Chondrocyte Implantation（ CS-ACI）
All procedures are carried out after obtaining informed written consent from patients. Cartilage tissue is acquired from the Non-weight-bearing area of patients. chondrocyte are isolated and grown in culture for 6-8 weeks. After this time interval, the cells are reprocessed and the cell sheet is obtained. Implantation of the chondrocyte sheet into the Cartilage defect of the keen.The patients will be assessed clinically with scoring systems preoperatively as well as 24 months postoperatively to assess relief of symptoms and joint function. Radiological assessment (MRIs)of the affected joints will be performed at the same time points aforementioned to assess integrity of the formed cartilage. Second look arthroscopy and biopsy will also be performed to histologically assess the repair tissue and grade it via arthroscopic grading system according to the International Cartilage Repair Society guidelines.
