Eksperimentel: arthroscopic microfracture with autologous adipose gel
The experimental group will be treated with arthroscopic microfracture with autologous adipose gel.
|
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
|
|
Aktiv komparator: arthroscopic microfracture
The control group will be treated with arthroscopic microfracture.
|
Surgeons routinely perform international standard micro-fracture surgery to repair cartilage damage
