Minimal incision is often favored because it minimizes the area of the incision, making it appear to the naked eye to have less post-operative damage.
However, it is very difficult to accurately determine the area between cartilage breaks, which are the cause of degenerative arthritis, and the puncture area is also very limited when implanting stem cells during surgery.
The most important thing in stem cell transplantation is the accurate puncture of the damaged area rather than the size of the incision.
