مفروش کردن بیولوژیک استخوان کشکک به جای برداشتن آن

In the past years, there was a tendency to excise the patella in pathologic conditions affecting this bone. The patella has many critical effects in the function of the knee joint. For example, after its exicision the force of quadriceps muscle decreases by forty percent (40%) and the knee joint becomes prone to early osteoarthritic changes. For these reasons, in the recent years the "biologic resurfacing of patella" has been used in pathologic conditions instead of its complete removal. In this new method after resection of the diseased part of the bone, the fascia of the quadriceps muscle, with its intact base, is used to cover the resected part of the bone. In practice, after pain relief, the active motion of the joint is started. Then the limb is placed in a splint or brace and after a period of 3 weeks, passive motion is begun.
