この1~2年の間にも股関節唇に対する内視鏡術には疑問符が投げかけられ、
医学系雑誌「The Journal of bone & Joint Surgery」では、関節唇損傷が必ずしも変形性股関節症へと進行するものではないと述べられています。
One recent study cast doubt. Dr. George Hartofilakidis and his colleagues at the
University of Athens in Greece followed 96 people with an average age of 49 with
hip impingement but no hip pain. They did not have impingement surgery. http://web.jbjs.org.uk/cgi/content/abstract/93-B/5/580
After 18 ½ years, 20 percent had developed arthritis, a rate that is not particularly
unexpected as people age. There was no reason to blame impingement for it. So
the researchers concluded that "prophylactic surgery is not warranted."
