NCT02770209

Brief Summary

This study is aimed at evaluating the feasibility and effectiveness of a completely natural tissue engineered cartilage, composed of a self-made tissue engineered oriented scaffold and autologous chondrocytes, for repairing articular cartilage damage following injury. And it is also aimed at investigating the safety of tissue engineered cartilage transplantation.

Study Arms (2)

the experimental group

EXPERIMENTAL

Patients in the experimental group will be treated with the biomimetic cartilage matrix combined with autologous chondrocytes. The entire course of treatment includes two surgeries. The first surgery will be performed to observe articular cartilage damage by arthroscopy and assess treatment potential. If the patient's condition meets the surgical requirement, we will extract cartilage from the fossa intercondylar non-weight-bearing area during the first surgery. Chondrocytes will be in vitro-amplified and inoculated into the cartilage scaffold. The fully prepared seeded scaffold will be implanted into the site of injury during the second surgery.

Biological: biomimetic cartilage matrix + autologous chondrocytes

the control group

EXPERIMENTAL

Patients in the control group will be subjected to arthroscopic debridement and microfracture surgery.

Procedure: arthroscopic debridementProcedure: microfracture surgery
