Arm 2

Arm Type

Experimental

Arm Label

Cartilage membrane surgery

Microfracture

Arm Description

The test group applied the guidance provided by Shaanxi Baiao Regenerative Medicine Co., Ltd. Cartilage regeneration membrane combined with microfracture surgery.

The control group was treated with microfractures widely recognized at home and abroad.

Outcomes

Primary Outcome Measures

MRI evaluation of articular cartilage injury 730 days (2 years) after repair
The nuclear magnetic evaluation indicators are as follows: Cartilage defect repair filling degree; Fusion of repair tissue and adjacent normal cartilage; Repair tissue surface structure; Repair the internal structure of the organization. The MRI score of the experimental group before and after treatment increased by an average of 5 points compared with the control group.

Secondary Outcome Measures

Change in ratio of regenerated cartilage T2 value to normal cartilage T2 value
The closer the ratio of the regenerated cartilage T2 value to the normal control cartilage T2 value is 1, it means that the regenerated cartilage The closer the water content and collagen arrangement are to normal cartilage.
Change in ratio of regenerated cartilage △R1 value to normal cartilage △R1 value
The closer the ratio of the regenerated cartilage △R1 value to the normal control cartilage △R1 value is 1, it means that the GAG content of regenerated cartilage is closer to normal cartilage.

5. Study Description

Brief Summary
Guided cartilage regeneration membrane for repairing the safety and effectiveness of articular cartilage injury
Detailed Description
MRI evaluation using guided cartilage regeneration membrane for articular cartilage injury repair 730 days (2 years) is the main indicator of this trial. In this experiment, we observe the improvement of Lysholm score, VAS score, ratio change of regenerated cartilage T2 value to normal cartilage T2 value, and ratio of regenerated cartilage △R1 value to normal cartilage △R1 value Indicators such as value changes are secondary evaluation indicators.
