Endoscopic total one-piece medial meniscectomy: its effect on the medial collateral ligament.

Meniscus specimens from 10 patients subjected to endoscopic total medial meniscectomy were examined for remnants of the collateral ligament. Very small amounts were found in the postero-medial area of the specimens. None exceeded 2 mm in length or breadth and could be formed in only one of the sections. With our technique for endoscopic total meniscectomy the integrity of the medial collateral ligament is not violated and ligamentous instability can be avoided.
