Study Overview
Brief Summary
The purpose of this research is to confirm the efficacy of cartilage regeneration (or stem cell transplant) simultaneously performed with high tibial osteotomy. Furthermore, as conventional microfracture surgery on injured cartilage has a disadvantage of the replacement by fibrocartilage, this research intends to prove the excellence over the conventional therapy by proving a hyaline cartilage regeneration of injured cartilage by stem cell.
Detailed Description
The prevalence rate of arthritis in medial knee joint is increasing with an increase in senile diseases and there are two main types of therapy: total knee replacement surgery and high tibial osteotomy. Generally, the elderly prefer total knee replacement surgery and younger people prefer high tibial osteotomy. High tibial osteotomy is a procedure to reduce pain and to prevent the progression of osteoarthritis by evenly dispersing excessive load on medial knee joint attributed to varus deformity on the overall knee joint through the correction of abnormal anatomical axis arising from degenerative changes in articular cartilage. The clinical outcomes of high tibial osteotomy are reported as favorable but this high tibial osteotomy has a limitation in terms of the regeneration of injured cartilage. Thus, a research to concurrently perform additional therapy for the regeneration of injured cartilage with the osteotomy was released. Microfracture surgery on injured cartilage, autologous chondrocyte implantation, autologous bone marrow injections and adipose derived stem cell injections are typical examples. However, there is not any solid proof for the excellence of concurrent therapy over a therapy using only the osteotomy in the regeneration of injured cartilage. Therefore, this research is designed to conduct a research to prove the excellence of the direct transplantation of stem cell into injured cartilage over the existing concurrent therapy in the regeneration of injured cartilage. Besides, this research intends to compare the cartilage regeneration capabilities of bone marrow and adipose-derived stem cell.
