Clinical Outcome After Episealer Talus Implant in Treatment of Osteochondral Lesion of the Talus
Sponsor: Stefano Zaffagnini
Summary
Autologous Chondrocyte Implantation (ACI) is an appealing technique whereby cartilage is harvested from the joint in a first operation. This biopsy is processed, individual cells are freed and cultivated and, in a second procedure, injected into the defect that has been covered by a periosteal graft). A second generation includes a matrix (MACI) into which the cells are injected/cultivated. Recently, collagen membranes are used to cover the cells or cover a micro-fractured defect. Good results have been reported although return to previous sports remains a challenge . Long term results are lacking. More important is the fact that these treatments are directed towards restoring the articular cartilage whereas the patient's symptoms are generated by the bone and not the cartilage. Treatment of an OCD with a small metallic implant has been tested in recent years. Results have been promising by some reports, while a high revision rates was reported by others. A recent 2-8 years follow-up study revealed a survival rate of 95 %
