A study of autologous stem cells therapy assisted regeneration of cartilage in avascular bone necrosis.

Application of 'regenerative medicine' has given a new hope to surgeons for the treatment of several chronic diseases and disorders including severe orthopedic conditions. There are a myriad of orthopedic conditions and injuries that presently have limited therapeutic treatments and could benefit from new developing therapies in regenerative medicine with the help of stem cell therapy[1]. Regenerative medicine therapies are mainly based on the applications of stem cells. Stem cells play a vital role in orthopedic treatments and the studies have shown to have promising results in repair of bone, tendon, cartilage including avascular necrosis (AVN), spondylitis etc. Bone and cartilage regeneration ability of stem cells has been demonstrated clinically. However, success rate may not be same in every case and it depends on the patient profile. Several factors can be responsible for the same which include patient's immune response, the type and grade of the disease, which along with other confounding factors decide the outcome of the treatment. In this paper we have presented some of the orthopedic case studies performed through autologous transplantation of the stem cells.
