Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this trial is to demonstrate superior efficacy and safety of MACI compared with arthroscopic microfracture in the treatment of patients (aged 18 to 55 years) with symptomatic articular cartilage defects of the knee.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, randomized, open-label, parallel-group, multicenter study designed to investigate the outcome of MACI implant versus arthroscopic microfracture in the treatment of articular cartilage defects in the knee in patients between ages of 18 and 55 years.

All patients who meet the eligibility criteria and are considered suitable for inclusion will have a cartilage biopsy taken prior to randomization to study treatment. Eligible patients will then be randomized during the index arthroscopy procedure to receive either MACI implant or microfracture treatment.

Patients randomized to treatment with MACI implant will return within approximately 4 to 8 weeks of the index arthroscopy to undergo the chondrocyte implantation procedure via arthrotomy. Patients randomized to microfracture will undergo the procedure during the index arthroscopy.

Patients will be assessed post-arthroscopy and post-arthrotomy at intervals during 2 years follow-up. Evaluations include adverse events, functional and pain outcomes, arthroscopic and histologic evaluation and magnetic resonance imaging (MRI).
