Treatment of Early Knee Osteoarthritis With Autologous Adipose-derived Mesenchymal Stem Cells

September 15, 2020 updated by: Qilu Hospital of Shandong University

Efficacy and Safety of Autologous Adipose-derived Mesenchymal Stem Cells in the Treatment of Early Knee Osteoarthritis

The purpose of this study is to explore the efficacy and safety of autologous adipose mesenchymal stem cells in the treatment of early knee arthritis. Investigator believes that autologous adipose mesenchymal stem cells can relieve pain, improve knee function, promote knee cartilage regeneration and improve life satisfaction of patients.

Study Overview

Detailed Description

Investigators extracted abdominal fat from eight patients, extracted autologous adipose mesenchymal stem cells and injected them into the knee joint of the patients. The data were followed up regularly after operation and compared with those before operation.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hospital for special surgery knee score postoperative 1 month
Time Frame: postoperative 1 month
Hospital for special surgery knee score is a knee function scoring system with a full score of 100. 0 means the loss of knee function, 100 means the best knee function, and the greater the value, the better knee function.
postoperative 1 month
Hospital for special surgery knee score postoperative 3 month
Time Frame: postoperative 3 month
Hospital for special surgery knee score is a knee function scoring system with a full score of 100. 0 means the loss of knee function, 100 means the best knee function, and the greater the value, the better knee function.
postoperative 3 month
Hospital for special surgery knee score postoperative 6 month
Time Frame: postoperative 6 month
Hospital for special surgery knee score is a knee function scoring system with a full score of 100. 0 means the loss of knee function, 100 means the best knee function, and the greater the value, the better knee function.
postoperative 6 month
Visual Analogue Scale Postoperative 1 month
Time Frame: Postoperative 1 month
Draw a 10 cm horizontal line on the paper. One end of the line is 0, indicating no pain; the other end is 10, indicating severe pain; and the middle part indicates varying degrees of pain. The patient selects a point from the horizontal line and the length from 0 to this point is the Visual Analogue Scale score.
Postoperative 1 month
Visual Analogue Scale Postoperative 3 month
Time Frame: Postoperative 3 month
Draw a 10 cm horizontal line on the paper. One end of the line is 0, indicating no pain; the other end is 10, indicating severe pain; and the middle part indicates varying degrees of pain. The patient selects a point from the horizontal line and the length from 0 to this point is the Visual Analogue Scale score.
Postoperative 3 month
Visual Analogue Scale Postoperative 6 month
Time Frame: Postoperative 6 month
Draw a 10 cm horizontal line on the paper. One end of the line is 0, indicating no pain; the other end is 10, indicating severe pain; and the middle part indicates varying degrees of pain. The patient selects a point from the horizontal line and the length from 0 to this point is the Visual Analogue Scale score.

Squatting to Standing Time postoperative 1 month
Time Frame: postoperative 1 month
The patient squatted on the floor and then stood up completely for five consecutive times, recording the time required.

Evaluation of cartilage repair under MRI postoperative 3 month
Time Frame: postoperative 3 month
Recht criterion was used for grading articular cartilage injury of knee joint, including 0-IV grade, in which: 0 grade, normal articular cartilage, no obvious abnormal signal was found; 1 grade, the layered structure of cartilage disappeared, and there were focal low signal areas, but the surface was smooth; 2 grade, the surface of cartilage was irregular, the depth of cartilage injury was less than 50% cartilage thickness; 3 grade, the surface of cartilage was heavy. The degree of injury is irregular, the depth of injury is more than 50% of the thickness of cartilage or through the whole layer, but the surface of cartilage is not completely exfoliated; Grade IV, full-thickness cartilage defect, articular cartilage injury deep to the cortex, subchondral bone exposed.

Degree of meniscus injury under MRI postoperative 3 month
Time Frame: postoperative 3 month

Stoller's criteria were used in the classification of meniscal injuries, including 0-3 grades, in which: 0 grade, the shape of meniscus was regular, complete and even low signal; 1 grade, focal ellipse or circular high signal appeared in the meniscus, which did not extend to the articular surface and margin of the meniscus; 2 grade, the meniscus showed horizontal linear high signal extending to the articular margin of the meniscus.

But it did not exceed the articular surface; in grade III, the shape of meniscus was irregular and incomplete. Irregular or linear high signal appeared in the meniscus and extended to the articular surface of meniscus. The grade I and II symptoms of meniscus injury were mild, suggesting meniscus degeneration, and grade III suggesting meniscus tear.
