Summary

This trial is testing GelrinC, a special gel designed to help repair damaged knee cartilage. It targets patients with knee cartilage defects who need effective treatment. The gel works by forming a support structure that helps new cartilage cells grow and repair the damaged area. GelrinC has shown significant improvement in radiological outcomes for treating chondral and osteochondral femoral cartilage lesions.

Who is the study for?
This trial is for adults aged 18-50 with a Body Mass Index (BMI) of 35 or less, who have a specific type of knee cartilage damage (ICRS III or IV) that's no larger than 5 cm2 and not deeper than 5 mm. The other knee must be healthy. People with additional severe lesions, recent bone conditions, untreated ligament issues, recent meniscus surgery, or past failed cartilage treatments can't join.
What is being tested?
The study tests GelrinC against an older method called microfracture in treating knee cartilage defects. It's conducted at multiple centers where patients are openly assigned to either the new treatment arm (GelrinC) or compared to historical data from the control group.
What are the potential side effects?
While specific side effects aren't listed here, typical risks may include pain at the injection site, swelling in the treated knee, infection risk due to surgery and possible adverse reactions to GelrinC material.
