Summary

This study looks at how well dissolving screws work to fix broken cartilage pieces in the knees of people aged 12 to 35. The goal is to see if this surgery helps prevent long-term problems like pain, stiffness, and early arthritis. Researchers will track symptoms and daily function using questionnaires and imaging over time.
