Combining a novel leucocyte-platelet-concentrated membrane and an injectable collagen scaffold in a single-step AMIC procedure to treat chondral lesions of the knee: a preliminary retrospective study.

Background: Different surgical approaches are currently available to treat knee chondral defects. Microfracture is the most commonly applied, but it often leads to a mechanically inferior fibrocartilaginous tissue. To overcome this shortcoming, the Autologous, Matrix-Induced Chondrogenesis (AMIC) technique has been proposed.

Percutaneous calcaneoplasty in displaced intraarticular calcaneal fractures.

The ideal treatment for displaced intraarticular calcaneal fractures is still under debate. Open reduction and internal fixation is the most popular surgical procedure; however, wound complications, hardware failure and infection remain a major concern. The aim of this study was to evaluate the results of a new minimally-invasive surgical procedure: closed reduction technique combined with balloon-assisted fracture augmentation with cement or calcium phosphate (minimally-invasive percutaneous calcaneoplasty).

Tibial plateau fractures: internal fixation with locking plates and the MIPO technique.

Proximal tibial fractures are difficult lesions to treat because of the involvement of the articular surface, the often occurring comminution, and the precarious condition of the soft tissues, especially following high-energy trauma. Aim of the treatment is to restore the congruence of the articular surface supporting the tibial plateau cartilage which is usually depressed; to fix the fracture with a stable device; to allow early rehabilitation. We present our treatment strategy, utilising closed or open reduction and internal fixation, angle-stable polyaxial plates, immediate osteointegration, when necessary, with autologous bone graft or other osteoconductive material augmented with autologous platelet gel.
