상세 설명
This is multicenter, prospective, randomized clinical trial, subjects will be randomized (2:1) to MaioRegen Prime or debridement.
All randomized patients will be followed with post-operative visits at 15 days, 6 weeks, 3, 6, 12, 18 and 24 months after surgery and annually post-24 months visit (until last patient reaches 24 months).
During screening period and at follow-up visits commonly used specific scores will be evaluated: IKDC Subjective Knee Evaluation Form, IKDC Knee Examination Form, KOOS, Tegner Score, VAS pain, PROMIS-29, ICRS Cartilage Repair Assessment and MRI related scores.

International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Score at 24 months of MaioRegen Prime compared to debridement
기간: baseline, 24 months
|
Subjective, knee-specific rating scale that is considered one of the most reliable assessment tools in the evaluation of knee pathologies. All questions examines 3 categories: symptoms, sports activity, and knee function. The IKDC Subjective Knee Evaluation Form is graded by adding the results of each item's scores, and then converting the result to a scale from 0 to 100. Higher scores indicate higher levels of function and lower levels of symptoms, (i.e., a better outcome). |

Rate of responder in IKDC Subjective Knee Evaluation at 24 months of MaioRegen Prime compared to debridement as defined as improvement in IKDC Subjective Knee Evaluation of ≥15 points
기간: baseline, 24 months
|
The new IKDC Subjective Knee Evaluation Form, published in 2000, is considered one of the most reliable assessment tools in the evaluation of knee pathologies. All questions examines 3 categories: symptoms, sports activity, and knee function. The IKDC Subjective Knee Evaluation Form is graded by adding the results of each item's scores, and then converting the result to a scale from 0 to 100. Higher scores indicate higher levels of function and lower levels of symptoms, (i.e., a better outcome). |

Change from baseline in average overall KOOS score (Knee Injury and Osteoarthritis Outcome Score)
기간: baseline, 12, 18, and 24 months
|
KOOS score consists of 5 subscales and covers: pain (9 items), symptoms (7 items, two of which are related to stiffness), functions and activities of daily living (17 items), physical function, sports and leisure activities (5 items) and quality of life in relation to the knee (4 items). Each question uses a 0 (no problem/difficulty) to 4 (extreme problem/difficulty) response, which is then converted into the final 0-100 score for each subscale, indicating the percentage of the total possible score achieved, with 0 representing extreme knee problems (i.e., worse outcome) and 100 representing no knee problems (i.e., better outcome). |

Change from pre-injury and from baseline in Tegner score
기간: baseline, 12 months, 18 months, 24 months
|
Tegner activity level scale allows to know the level of physical activity carried out by the patients. Tegner's activity scale classifies the activity according to work and sports activities on a scale from 0 to 10, where 0 is being on sick leave/disabled due to knee issues, and 10 is elite, international competitive sports. |

Change from baseline in IKDC (International Knee Documentation Committee) Knee Examination Objective Form
기간: baseline, 12 months, 18 months, 24 months
|
The IKDC objective examination form uses a 0-100 scale, calculated by summing seven parameters related to knee function. The presence of effusions and degree of knee motion are assessed; the worst value of any of these parameters determines the final IKDC grade. There are four grades (A, B, C, D) that identify a knee rated as normal, near normal, abnormal, and severely abnormal, respectively. |

|
Change from baseline in VAS (visual analogue scale) pain
기간: baseline, 12 months, 18 months, 24 months
|
The VAS scale is a 0-cm line tool to measure pain intensity, with "no pain" at 0 and "worst pain imaginable" at 10, where patients mark their pain level |

PROMIS-29 (Patient-Reported Outcomes Measurement Information System): Patient's QOL (quality of life) improvement
기간: baseline, 12 months, 18 months and 24 months
|
The PROMIS-29 uses a T-score metric (mean 50, SD 10) to assess 7 domains (Physical Function, Fatigue, Depression, Anxiety, Pain Interference, Sleep Disturbance, and Social Participation) with 4 questions with an additional pain intensity numeric rating scale (NRS, 0-10 score). There is no total score, but each axis forms its own score. |

MRI evaluation: MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) 2.0 Knee Score
기간: baseline, 12 months, 24 months
|
MOCART 2.0 score allows the assessment of both cartilage tissue repair and the structures surrounding it. It is a 0-100 point MRI-based system for evaluating cartilage repair, updating the original MOCART by focusing on nine key variables like defect filling (in 25% increments), integration to native cartilage, surface, signal intensity, bony changes (overgrowth/defect), marrow edema, and subchondral cysts. 100 represents the best score and a score of 0 represents the worst score. |
