The original version of this article contained mistakes, and the authors would like to correct them. The correct details are given below:

• Fig. 4 A. In the GPO group, the S-O and H-E staining pictures were used incorrectly. This is our mistake.

Fig. 4
figure 1

The addition of GPO reduced the cartilage destruction in the OA ratmodel, assayed by Safranin-O staining, as well as H&E staining (a). Rat received intraperitoneal injections of GPO or vehicle (DMSO) during the fourth week after surgery. The OARSI score was calculated for each group (b). Values are mean ± SD. Significant differences from the control group are indicated by * P  < 0.05. Significant differences from the OA group are indicated by # P  < 0.05.

• Fig. 4 B. The name of the GPO drug treatment group is wrong, and the correct name should be OA+GPO.

The correct figure 4 can be seen at the next page.

The authors apologize for potential issues raised by these mistakes.
