Treatment of Achilles tendon partial injuries with injection of peripheral blood mononuclear cells (PB-MNCs): a case series.

Three patients with Achilles tendon partial injury were treated with local injection of peripheral blood mononuclear cells (PB-MNCs). All subjects were evaluated both clinically (American Orthopedic Foot and Ankle Society - AOFAS scale) and radiologically (MRI examination) at 2 months, and a clinical reassessment with the AOFAS scale was performed at 6 months. Functional and radiological signs of tendon healing processes were detected as early as 2 months after the procedure and the AOFAS scale rose from an initial average value of 37.

CT arthrography for evaluation of autologous chondrocyte and chondral-inductor scaffold implantation in the osteochondral lesions of the talus.

Purpose: to analyse the findings of CT arthrography of the ankle, one year after the transplant of autologous chondrocytes in solution (ACI technique) and the covering with the only scaffold implantation of the osteochondral lesions of the talus, in comparison with the clinical evaluation of the ankle.

Methods: This retrospective study includes 10 patients (6 male, 4 female, mean age 49.4, range 25-74 years) with an osteochondral lesion of the medial side of the talus, 4 pure chondrals, 6 osteochondrals, painful and limiting the articulation, who underwent ACI using autologous chondrocyte (5 cases) and a covering with the only scaffold implantation (5 cases), in patients who underwent multi-detector CT arthrography between April 2006 and December 2013, at least 12 months after the surgery.
