Matrix-induced autologous chondrocyte implantation grafting in osteochondral lesions of the talus: Evaluation of cartilage repair using T2 mapping

Publication date: Available online 2 May 2019Source: Journal of OrthopaedicsAuthor(s): P. Correa Bellido, J. Wadhwani, E. Gil MonzoAbstractOsteochondral lesions of the talus may be treated with different autologous biological approaches. These include platelet-rich plasma, stem cells or MACI and ACI. MACI implants are used to cover cartilage lining defects in the ankle. A total of 18 patients were treated with MACI implants. NMR images were taken before and after the procedure. T2 mapping was used to quantify the changes in cartilage collagen after a 6–12-month postoperative period. Increase in collagen was recorded on all patients. Both open and arthroscopic procedures were performed depending on the technical difficulties encountered during the repair.
