Treatment of patellofemoral chondropathy with BIOART

The patella is a sesamoid bone, roughly triangular in shape, placed inside the quadriceps muscle tendon. This bone, articulating with the trochlear groove of the femur, mechanically constitutes the fulcrum of extensor mechanisms of the lower limb. Both the articular surfaces of the patella itself and those of the trochlear sulcus are covered by an articular cartilage that is on average 4 to 6 mm thick [1,2]. The normal sliding mechanisms of the patellofemoral joint are controlled by static factors, i.e. non-contractile and dynamic, i.e. contractile. Static factors are represented by the patella size, femoral condyles and their size, the shape/angle of the trochlear sulcus and the alignment of the lower limb [3-6].
