A trial determining whether injections of local anaesthetic in front and behind the hip can make arthroscopic hip surgery less painful
In patients having arthroscopic hip surgery are ultrasound guided anterior and posterior pericapsular injections of local anaesthetic as good as or better than injections of saline alone for relief of pain following surgery

Conditions
Summary
Many patients find hip arthroscopy surgery to be very painful in the first few hours following the operation. We think this may be due to the swelling of the hip joint capsule that occurs during this type of surgery. The purpose of this study is to determine whether injecting local anaesthetic medication on both the front and the back of the hip joint, at the start of the operation, will make this surgery less painful.
