Video Summary

In this video, the speaker presents a study on the use of a collagen meniscus implant (CMI) as a scaffold for partial meniscus defects. The surgical technique involves arthroscopy and suturing the CMI in place. The study included 156 patients with a follow-up time ranging from 5 to 11 years. The outcomes measured were surgical failure (including infection, dislocation, and knee replacement) and clinical failure (poor function or need for a second surgery). The results showed an overall survival rate of 88% for surgical failure and 70% for clinical failure. Lateral CMIs had a lower survival rate compared to medial CMIs, and cartilage status played a significant role in outcomes. The timing of meniscectomy also influenced results. Overall, the CMI provided satisfactory long-term results, with 90% of the scaffolds still in place after 10 years. The speaker credits their colleagues and mentors who contributed to the study.
