If arthroscopic surgeries are so much better than open surgeries, how come not all are done that way now?

Arthroscopic surgery, which involves making a few tiny incisions, perhaps only a few centimeters long, and using long slender instruments and a camera to see inside the body, has many advantages over traditional open surgery where a large incision is made and the surgeon reaches inside to perform the repair. However, some surgeries are on too big a scale for arthroscopy and some do not have the same results, open surgery is more effective. When a surgeon is deciding how to approach a surgery, he or she will take many things into consideration. For example, removing an appendix is done very frequently using arthroscopic surgery. However, if the appendix is threatening to burst or has burst, it must be removed using an open technique because of the work involved in ensuring every thing has been taken care of properly.
