No Difference in Chondrocyte Viability Using Manual Versus Custom-Cutting Technique for Matrix-Induced Autologous Chondrocyte Implantation.

ABSTRACT:

Background

Matrix-induced autologous chondrocyte implantation (MACI) was developed for knee cartilage restoration involving seeding autologous chondrocytes onto a collagen membrane. Maintaining chondrocyte viability and achieving proper membrane size and contour are crucial for successful outcomes. Scissor cutting (Sc) has traditionally been used to shape the membrane, but recently, custom cutting (CC) have gained popularity for their enhanced preparation efficiency.

Purpose

To determine the difference in chondrocyte viability using the Sc versus CC methods.

Study design

Controlled laboratory study.

Methods

Using Sc and CC methods, 15 mm-diameter circular specimens were cut from 5 residual membranes. Membranes were stained, and confocal microscopy was used to v
