Lesion identification:

Osteochondral lesion of the left knee femoral trochlea in a 47 year old patient, due to sport trauma (judo).

Arthroscopic procedure/Defect preparation:

The arthroscopic procedure was performed using the standard anterolateral and anteromedial approaches. After joint inspection, debridement of the osteochondral lesion was performed to remove fibrous tissue and to obtain a stable wall of healthy cartilage and subchondral bone.

Microfractures:

Microfractures were then made in the exposed bone about 3 to 4mm apart according to Steadman technique.

CO₂ joint distension:

Before product application, CO₂ can be used to obtain joint cavity distension in order to gain a better view of the lesion and to facilitate the scaffold positioning.

HYALOFAST^® shaping and arthroscopic application:

The HYALOFAST^® scaffold was cut to fit the chondral defect and then inserted directly into the articular cavity through the arthroscopic portal and gently adapted to the chondral defect by using a probe. The fast adhesion of HYALOFAST^® scaffold into the osteochondral defect was obtained without application of fibrin glue or other fixation means.
