# Arthroscopic Cartilage Repair of the Patella With Minced Cartilage and Collagen Membrane Scaffold With Bone Marrow Aspirate Concentrate

## TL;DR

This paper presents an arthroscopic method for repairing patellar cartilage using a collagen scaffold, bone marrow, and minced cartilage.

## Contribution

The novel contribution is an all-arthroscopic technique using a bilayer collagen scaffold and bone marrow aspirate concentrate.

## Key findings

- The technique is designed for single-stage patellofemoral cartilage repair.
- It uses a porcine-derived collagen scaffold augmented with minced cartilage and bone marrow aspirate concentrate.
- The method aims to improve upon previous open mini-arthrotomy approaches.

## Abstract

The single-staged repair technique of patellofemoral cartilage lesions has previously been described, with the utility of a bilayer scaffold and minced cartilage via an open mini-arthrotomy, showing great clinical efficacy. We describe a procedure similarly aimed at addressing patellofemoral lesions but with an all-arthroscopic approach, using a porcine-derived collagen I/III bilayer scaffold augmented with bone marrow aspirate concentrate and minced cartilage.
