Studio MaioRegen Prime per il Trattamento delle Lesioni Osteocondrali Profonde del Ginocchio (OSTEOCONFIRM)

3 ottobre 2026 aggiornato da: Fin-Ceramica Faenza Spa

Studio Prospettico Randomizzato Multicentrico di MaioRegenTM Prime vs. Debridement (Standard Chirurgico di Cura (SSOC)) per il Trattamento della Lesione Osteocondrale dell'Articolazione del Ginocchio - Studio OSTEOCONFIRM

The present study aims to compare the efficacy and the safety of MaioRegen Prime to Debridement (SSOC) in patients with deep osteochondral lesions of the knee joint. The foreseen population involves patients with osteochondral lesions with different etiology, dimension, shape, and location.

The evaluation will be performed through clinical, subjective and objective assessments.

Misura Descrizione
Lasso di tempo
Superiority of MaioRegen Prime vs Debridement
Lasso di tempo: baseline, 24 months

The primary endpoint is the success rate defined as a composite binary endpoint, where a patient is a success if they meet all of the following criteria:

  • At least a 15 points IKDC increase at 24 months
  • Lack of SAE related to MaioRegen treatment or debridement during the 24-month follow-up
  • Lack of related re-intervention after MaioRegen treatment or debridement during the 24-month follow-up

International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Score at 24 months of MaioRegen Prime compared to debridement
Lasso di tempo: 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).

baseline, 24 months
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
Lasso di tempo: 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).

baseline, 24 months
Change from baseline in average overall KOOS score (Knee Injury and Osteoarthritis Outcome Score)
Lasso di tempo: 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).

baseline, 12, 18, and 24 months
Change from pre-injury and from baseline in Tegner score
Lasso di tempo: 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.

baseline, 12 months, 18 months, 24 months
Change from baseline in IKDC (International Knee Documentation Committee) Knee Examination Objective Form
Lasso di tempo: 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.

baseline, 12 months, 18 months, 24 months
Change from baseline in VAS (visual analogue scale) pain
Lasso di tempo: 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
Lasso di tempo: 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.

baseline, 12 months, 18 months and 24 months
MRI evaluation: MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) 2.0 Knee Score
Lasso di tempo: 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.
