Trial Summary

What is the purpose of this trial?

This trial focuses on patients who did not respond to initial Microfracture treatment. The Microfracture procedure creates small holes in the bone to stimulate new cartilage growth, helping repair knee damage. Microfracture is a widely used technique for treating cartilage defects in the knee by creating small holes in the bone to stimulate new cartilage growth.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment NOVOCART 3D for articular cartilage injury?

The NeoCart implant, a similar autologous cartilage tissue treatment, showed positive short-term results in clinical trials, indicating it was safe and effective compared to microfracture for knee cartilage injuries. ^{1 2 3 4 5}

How is the NOVOCART 3D treatment different from other treatments for articular cartilage injury?

NOVOCART 3D is unique because it is a matrix-based autologous chondrocyte implantation (ACI) that uses a biocompatible structure to support the growth of the patient's own cartilage cells, potentially reducing complications like graft hypertrophy (excessive tissue growth). This approach differs from traditional methods like microfracture, which involves creating small holes in the bone to stimulate cartilage growth, as it directly uses the patient's cells to repair the cartilage. ^{1 3 4 5 6}

Findings from Research

The MOCART 2.0 knee score shows improved interrater reliability compared to the original MOCART score, with an ICC of 0.875, making it a more reliable tool for assessing cartilage repair tissue in patients who have undergone various cartilage repair procedures.

This study, which included 114 patients with different types of cartilage lesions, found that the MOCART 2.0 score is effective for evaluating repair tissue across multiple techniques (like ACI and microfracture) and demonstrated better reliability for osteochondral lesions compared to chondral lesions.

The NeoCart implant, a tissue-engineered collagen matrix with autogenous chondrocytes, significantly reduced pain in patients with full-thickness cartilage injuries at 12 and 24 months post-implantation, indicating its efficacy in treating knee cartilage damage.

MRI evaluations showed that most patients (6 out of 8) achieved substantial defect fill (67% to 100%) and demonstrated stable integration of the implant without complications like arthrofibrosis or overgrowth, suggesting the safety and effectiveness of the NeoCart in cartilage repair.

An autologous cartilage tissue implant NeoCart for treatment of grade III chondral injury to the distal femur: prospective clinical safety trial at 2 years. Crawford, DC., Heveran, CM., Cannon, WD., et al.[2019]

In a study of 41 patients with knee cartilage defects treated with NOVOCART 3D implants, graft hypertrophy occurred in 11 patients over a 2-year follow-up, particularly in those with defects resulting from acute trauma or osteochondritis dissecans (OCD).

The modified MOCART Score indicated significant improvement in the quality and integration of the NOVOCART 3D implants post-surgery, suggesting that while graft hypertrophy is a concern, the overall treatment shows positive outcomes in cartilage repair.
