NCT04955548

Brief Summary

66 articular cartilage injury diseases patients were divided into two groups as 1:1. The test group will be treated with arthroscopic micro-fracture with autologous adipose gel, and the control group will be treated with arthroscopic micro-fracture. Postoperative MRI evaluation, Lysholm score, IKDC score, Tegner score, and VAS score will be used as the treatment validity evaluation index, at the same time testing blood routine, blood biochemistry, urine routine, CRP, electrocardiogram and other laboratory tests and recording the occurrence of adverse events.

Outcome Measures

Primary Outcomes (1)

  • Assessing a change of MRI Evaluation of Articular Cartilage Injury after Repair

    Assessing a change of postoperative MRI evaluation with autologous fat glue combined with micro-fracture treatment or micro-fracture treatment articular cartilage injury

    Knee MRI examinations were performed on patients baseline, 5 days, 90 days, 180 days, and 365 days after operation.

Secondary Outcomes (4)

  • Lysholm score

    Lysholm score was tested for the two groups of patients' baseline, 5 days, 90 days, 180 days, and 365 days after operation.

  • IKDC score

    IKDC score was tested for the two groups of patients' baseline, 5 days, 90 days, 180 days, and 365 days after operation.

  • Tegner score

    Tegner score was tested for the two groups of patients' baseline, 5 days, 90 days, 180 days, and 365 days after operation.

  • VAS score

    VAS score was tested for the two groups of patients' baseline, 5 days, 90 days, 180 days, and 365 days after operation.

Study Arms (2)

arthroscopic microfracture with autologous adipose gel

EXPERIMENTAL

The experimental group will be treated with arthroscopic microfracture with autologous adipose gel.

Procedure: arthroscopic micro-fracture with autologous adipose gel

arthroscopic microfracture

ACTIVE COMPARATOR

The control group will be treated with arthroscopic microfracture.

Procedure: arthroscopic micro-fracture

Interventions

Fully cut the adipose tissue taken out under the arthroscopy, transfer the cut adipose tissue to a syringe connected with a double pass, push back and forth through the syringe to physically emulsify the adipose, and centrifuge to obtain the autologous adipose gel, and inject it into the lesion

arthroscopic microfracture with autologous adipose gel

Surgeons routinely perform international standard micro-fracture surgery to repair cartilage damage
