Abstract
\nPurpose
Osteochondral lesions of the talus (OLT) usually require surgical treatment. Regenerative techniques for hyaline cartilage restoration, like autologous chondrocytes implantation (ACI) or bone marrow derived cells transplantation (BMDCT), should be preferred. The aim of this work is comparing two clusters with OLT, treated with ACI or BMDCT.
Methods
Eighty patients were treated with regenerative techniques, 40 with ACI and 40 with BMDCT. The two groups were homogenous regarding age, lesion size and depth, previous surgeries, etiology of the lesion, subchondral bone graft, final follow-up and pre-operative AOFAS score. The two procedures were performed arthroscopically. The scaffold was a hyaluronic acid membrane in all the cases, loaded with previously cultured chondrocytes (ACI) or with bone marrow concentrated cells, harvested in the same surgical session (BMDCT). All the patients were clinically and radiologically evaluated, using MRI Mocart score and T2 mapping sequence.
