Comparison of Efficacy and Safety of Microfracture and Modified Microfracture
Study Details
Study Description
Brief Summary
This study was designed to evaluate the efficacy and safety of a modified microfracture using collagen, and to compare them with those of a simple microfracture to prove the non-inferiority of the modified microfracture using collagen in patients with cartilage defects in their knees.

Detailed Description
This study was an open-trial study. One hundred subjects participated in it. The study was explained to the subjects and they voluntarily agreed to participate in it. Their eligibility to participate in the study was checked, and they were randomized either into the simple microfracture group or the modified microfracture group using collagen based on a centrally controlled randomization table. They were asked to follow the guidelines of the investigators during the study and to visit the hospital six times*, including for screening. At each visit, the subjects underwent an examination with doctors, a blood test, an X-ray procedure, an MRI, an observation with the naked eyes, and arthroscopy to evaluate the safety and efficacy of the procedure. (*If the screening date overlaps with the procedure date, the number of his or her visits would be five.)

Outcome Measures
Primary Outcome Measures
- 100mmVAS(Visual Analogue Scale) [12 month after surgery]
It will be evaluated by the VAS score 12 months after surgery of the affected knee of the investigational group and the control group.
Secondary Outcome Measures
- change of 100 mmVAS (Visual Analogue Scale) [screening, 3, 6, 12 and 24 months after surgery]
The difference between the VAS scores of the affected knee at the screening and 12 months after surgery in the investigational group will be compared to that in the control group. The differences in the VAS scores obtained at the follow-ups (3, 6, and 24 months after surgery) will be compared.
- change of Knee injury and osteoarthritis outcome (KOOS) [screening, 6, 12 and 24 months after surgery]
The difference between the KOOS scores of the affected knee at the screening and 12 months after surgery in the investigational group will be compared to that in the control group. The differences in the KOOS scores obtained at the follow-ups (6 and 24 months after surgery) will be compared.
- change of International Knee Documentation Committee (IKDC) [screening, 6, 12 and 24 months after surgery]
The difference between the IKDC scores of the affected knee at the screening and 12 months after the surgery in the investigation group will be compared to that in the control group. The differences in the IKDC scores obtained at the follow-ups (6 and 24 months after surgery) will be compared.
- the results of MRI and MRI of articular cartilage examination (T2, T2 star, deGEMRIC, UTE, etc.), mMOCART [12 months after surgery]
The results obtained 12 months after the surgery on the affected knee in the investigational and control groups will be described. mMOCART will be obtained, and the difference will be assessed. * Depending on the MRI equipment, if in-house imaging is not possible, it may be done at the other hospitals conducting the research.
