|Condition or disease||Intervention/treatment||Phase|
|Articular Cartilage Defect Chondral Defect Osteochondritis||Other: autologous chondrocytes||Not Applicable|
- Prospective and interventional study
- All procedures are carried out after obtaining informed written consent from patients.
- Study procedures involve a biopsy, cell production, cell implantation and follow-up including a strict post-surgery rehabilitation protocol (12 month timepoint)
- All subjects will be assessed at intervals post-implantation (6 weeks, 3 months, 6 months and 12 months).
- Measures to assess effectiveness and safety will be conducted at follow-ups: Magnetic Resonance Imaging (MOCART score), collection of adverse events, orthopaedic scores (KOOS, IKDC, SF12v2)
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||100 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Introduction of Autologous Chondrocyte Implantation Procedure for the Treatment of Chondral Defect in the Knee|
|Actual Study Start Date :||September 1, 2017|
|Estimated Primary Completion Date :||September 1, 2025|
|Estimated Study Completion Date :||September 1, 2025|
Experimental: Autologous Chondrocyte Injection
Autologous chondrocytes were isolated and expanded in laboratory, then injected at 2x10^6 of cells per cm^2 of the cartilage defect.
Other: autologous chondrocytes
autologous chondrocytes implantation (ACI)
- Rate of implantation-associated complications: serious adverse events (SAEs) and serious adverse reactions (SARs) [ Time Frame: Up to 12 months. ]Post-implantation data collection: Types, probability and severity of treatment (inflammation, infection,pain, joint effusion, delamination, transplant rejection, fibrocartilage, incomplete cartilage reparation).
- Change in tissue integrity into and around the treated aera [ Time Frame: 3 months post-implantation ]MRI analysis
- Absence of infection after implantation. [ Time Frame: 6 weeks post-implantation ]Absence of infection is assessed in blood sample by the quantification of three parameters: C-reactive Protein (CRP), neutrophil and lymphocyte rate. The non-infection is characterised by a CRP rate < 10 mg/L, neutrophil rate ranges from 40-75% and lymphocyte rate ranges from 25-40%.
- Self-reported function and knee-related quality of life are assessed by using the Knee injury and Osteoarthritis Outcome Score (KOOS) [ Time Frame: Change from baseline to 12 months post-implantation. ]KOOS includes five subscales: symptoms, pain, activities of daily living, function in sport/recreation, and knee-related quality of life. A score in points for each subscale will be calculated, and it ranges from 0 (worst score) to 100 (best score).
- Self-reported physical pain and function are assessed by International Knee Documentation Committee score (IKDC) [ Time Frame: Change from baseline to 12 months post-implantation ]A score will be calculated, and it ranges from 0 (worst score) to 100 (best score).
- Self-reported functional health and weel-being as assessed by SF12 Survey [ Time Frame: Change from baseline to 12 months post-implantation ]SF12 survey includes 2 subscales: mental component summary (MCS) and physical component summery (PCS). A score in points for each subscale will be calculated, and it ranges from 0 (worst score) to 100 (best score).
- The cartilage repair is assesed by Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system. [ Time Frame: Change from baseline to12 months post-implantation ]MOCART scoring system is based on MRI analysis. A score in points will be calculated, and it ranges from 0 points (no repair) to 100 points (excellent cartilage defect repair)
