Intracapsular Injection of Human Umbilical Cord Mesenchymal Stem Cells for the Treatment of Knee Osteoarthritis (KOA UC-MSCs)

6 novembre 2026 aggiornato da: Beijing Hospital

Evaluating the Efficacy of Intra-articular Injection of Human Umbilical Cord Mesenchymal Stem Cells for Treating Knee Osteoarthritis

This is a self-controlled study comparing both knees. A total of 20 participants are planned to be enrolled. Among the first 10 participants, the same patient received 50 million mesenchymal stem cells and 2 ml of hyaluronic acid solution mixture in one knee as the experimental group, while the other knee was treated with 2 ml of hyaluronic acid injection solution as the control group. The first 10 patients did not experience any serious adverse events. After re-enrollment of the next 10 patients, the same patient was given 100 million mesenchymal stem cells and 2 ml of hyaluronic acid sodium mixture to one knee, while the other knee was given 2 ml of hyaluronic acid sodium injection as the experimental group. Compare the therapeutic effects between the two knees and among different doses.

Armi e interventi

Intervento / Trattamento
Sperimentale: treatment group

First, 10 subjects were enrolled. For one knee joint of each subject, a mixture of 5 million HUCMSCs and 2 ml of sodium hyaluronate was administered as the experimental group. If no serious adverse reactions occurred among the first 10 patients, the remaining 10 subjects were enrolled, and the other knee joint of each subject was treated with 100 million HUCMSCs and 2 ml of sodium hyaluronate as the experimental group.

Procedure for knee joint injection: The patient lies on their back, with the knee joint flexed at 90 degrees. The knee joint is disinfected with iodine and alcohol, and a sterile sheet is laid out. The puncture point for the knee joint is selected at the inner or outer knee crease or the supra-patellar bursa approach. Using a joint cavity puncture needle (a 19-gauge needle), insert the needle vertically through the skin at the puncture point. There is a slight sense of firmness when passing through the joint capsule, and a feeling of emptiness when it is broken through. There is no resistance when injecting the fluid, and the drug can be injected.
