APEX Optimizing Surgical Outcomes for Knee & Shoulder Arthroscopy-Track 2: Optimizing Cartilage Restoration: Microfractures, OATS

Video Transcription

Video Summary

Dr. Cruz from Mexico City discusses strategies to optimize cartilage repair in knee chondral injuries. He explains articular cartilage’s organized, location-dependent structure and common causes of chondral lesions such as trauma, overload, aging, and instability. Treatments range from conservative medication and rehabilitation to surgical approaches including joint lavage, microfractures, osteochondral autograft transfers (OATS), and allografts. Microfracture stimulates fibrocartilage growth but has limitations like reduced durability (around 2 years) and poorer outcomes in certain knee areas. Osteochondral grafts transfer healthy cartilage but require precise alignment and are better for single lesions around 10mm. Newer "microfracture plus" techniques combine microfracture with collagen or synthetic meshes to improve repair quality. Dr. Cruz emphasizes careful lesion preparation, proper graft placement, and early mobilization to prevent complications. While some advanced methods face accessibility and cost issues, tailored treatment based on lesion size and patient activity level is crucial for successful cartilage repair.
