Video Summary

Post-meniscectomy syndrome is knee pain following partial or total meniscus removal. The meniscus, composed mainly of type 1 collagen and fibrocartilaginous cells, plays a critical role in load transmission, joint stability, and cartilage preservation. Meniscectomy increases pressure and accelerates joint degeneration, with deterioration proportional to meniscus loss. Meniscal extrusion—a displacement beyond the tibial plateau—complicates transplant success. Meniscal transplantation, using fresh-frozen cadaver grafts, is indicated for complete defects, ideally in patients under 50 with good alignment and stable knees. Advanced cartilage damage predicts worse outcomes. Improved surgical techniques and patient selection have led to favorable long-term results, making transplantation a viable alternative to osteotomy or partial knee replacement.
