The trial evaluates the clinical efficacy and safety of decalcification bone scaffold for cartilage lesions of the knee. Half of participants will receive decalcification bone scaffold combined with microfracture, while the other will only receive microfracture as a control group.
Decalcification bone scaffold is a tissue engineering scaffold with the closest biomechanics and structure of normal cartilage. The objective of the study is to evaluate the clinical efficacy of arthroscopic decalcification bone scaffold combined with microfracture in the repairment of articular cartilage defects by randomized controlled trial. Sixty patients with clinically diagnosed knee cartilage injury according to 1: 1 were divided into experimental group and control group. The experimental group will be treated with decalcification bone scaffold combined with microfracture .The control group will be treated with microfracture . The patients will be treated by the same surgeon in this study group. MRI evaluation, Lysholm score, IKDC score, Tegner score, VAS score are selected as the measures of outcome, while the blood routine, blood biochemistry, urine, CRP, ECG and other laboratory tests will be recorded inclduing the incidence of adverse events.

Evaluate the articular cartilage postoperatively by MRI.
Time frame: 5 years
Lysholm score
The Lysholm score consists of eight items including limping, locking, pain, stair climbing, use of supports, instability, swelling, and squatting. The higher values represent a better outcome.
Time frame: 5 years
International Knee Documentation Committee (IKDC) 2000
International Knee Documentation Committee (IKDC) 2000. The higher values represent a better outcome.
Time frame: 5 years
Tegner activity level score
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.
Time frame: 5 years
Visual analogue scale
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.
Time frame: 5 years
