Stemming from the Greek arthro (joint), and skopein (to look), arthroscopic surgery redefines the conventional definition of surgery by making a small incision and inserting "pencil--sized instruments" to expose the structures inside the joint. This allows surgeons to not only finalize a diagnosis, but operate with little collateral damage to other areas of the body. By maximizing efficiency and minimizing unnecessary steps, arthroscopic surgery has become the best form of surgery for joint injuries and diseases. The necessity of arthroscopy speaks for itself. It is stored as the final piece in an arsenal of medical tools used for diagnosing injuries and diseases. Following a "thorough medical history", a physical examination, occasionally X-rays, with the usual MRI or CT scan, arthroscopic surgery seals a diagnosis with more accuracy than "open" surgery or X-ray, MRI, and CT studies.
Because of the noticeably reduced physical wear and tear on the body, arthroscopic patients are almost always treated as outpatients and are home within hours of the surgery. The overall healing process and rehabilitation is reduced favorably for patients. As opposed to "open" surgery, the tiny incision and the work that takes place inside that incision minimizes bleeding and shows a sizable reduction in complications, physical pain and infections, proving that arthroscopy should be considered a standard.
For patients searching for a path that reduces unfavorable complications and increases efficiency and accuracy, arthroscopic surgery is the obvious road to travel.
