Kenji Takagi
Professor Kenji Takagi (1888–1963) was a Japanese orthopedic surgery, orthopedic surgeon, noted for being one of the first people to carry out a successful arthroscopy of the knee. Takagi was attached to Tokyo University (where he succeeded Yoshinori Tashiro) in 1918 when he carried out the ground-breaking operation on a cadaver. He had been influenced by the work of Danish surgeon Severin Nordentoft. In 1922, he went to Germany to study the use of x-ray technology there. Following World War II, Takagi's pupil Masaki Watanabe (surgeon), Masaki Watanabe, carried on his work.

Orthopaedics
Orthopedic surgery or orthopedics ( alternatively spelt orthopaedics), is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders. Etymology Nicholas Andry coined the word in French as ', derived from the Ancient Greek words ὀρθός ''orthos'' ("correct", "straight") and παιδίον ''paidion'' ("child"), and published ''Orthopedie'' (translated as ''Orthopædia: Or the Art of Correcting and Preventing Deformities in Children'') in 1741. The word was assimilated into English as ''orthopædics''; the ligature ''æ'' was common in that era for ''ae'' in Greek- and Latin-based words. As the name implies, the discipline was initially developed with attention to children, but the correction of spinal and bone deformities in all stages of life eventually ...

Arthroscopy
Arthroscopy (also called arthroscopic or keyhole surgery) is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision. Arthroscopic procedures can be performed during ACL reconstruction. The advantage over traditional open surgery is that the joint does not have to be opened up fully. For knee arthroscopy only two small incisions are made, one for the arthroscope and one for the surgical instruments to be used in the knee cavity. This reduces recovery time and may increase the rate of success due to less trauma to the connective tissue. It has gained popularity due to evidence of faster recovery times with less scarring, because of the smaller incisions. Irrigation fluid (most commonly 'normal' saline) is used to distend the joint and make a surgical space. The surgical instruments are smaller than traditional instruments. ...

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masaki Watanabe (surgeon)
Masaki Watanabe (渡辺 正毅, 1911 – 15 October 1995) was a Japanese orthopedic surgeon, sometimes called the "founder of modern arthroscopy". Watanabe developed the first practical arthroscope. Watanabe was born in Nagano and graduated from Tokyo Imperial University in 1937. He studied surgery under Professor Kenji Takagi, who, towards the end of World War I, had been one of the first surgeons to attempt to insert an endoscopic device into a patient. After World War II, Watanabe became director of the Department of Orthopedic Surgery at Tokyo Teishin Hospital, where he developed early arthroscopes during the 1950s, and, in 1958, he introduced the Watanabe no 21 arthroscope, which was equipped with a superior handmade lens. When top Canadian orthopedic surgeon Robert W. Jackson visited Tokyo with the Canadian Olympic team in 1964, he came into contact with Watanabe, and this was the catalyst for the introduction of modern arthroscopic techniques into North America.
