The trial is looking for adults having a first reverse shoulder replacement. It tests whether lengthening the conjoint tendon during surgery reduces pain in the front of the shoulder at one year.

Age
18 years and older
Sex
All sexes
Disease stage
Shoulder osteoarthritis treated with a first (primary) reverse total shoulder replacement. Surgery must take place at Loyola University Medical Center, Loyola Ambulatory Surgery Center (Maywood, IL) or Gottlieb Memorial Hospital.
Earlier treatment
People who had a coracoid transfer procedure before cannot join. People having a repeat surgery to replace an earlier shoulder replacement cannot join.

Main reasons for not taking part

  • Younger than 18 years
  • Prior coracoid transfer procedure
  • Revision surgery of an earlier shoulder replacement
  • Current pregnancy (a urine pregnancy test is done before surgery)

About the trial

What the trial wants to find out

Some patients may experience persistent pain in the front of their shoulder after reverse shoulder replacement. One of the possible reasons for this is that the surgery causes a change in the alignment of the shoulder joint, which may cause increased tension and compression on one of the biceps tendon called the conjoint tendon. The purpose of this study is to evaluate whether conjoint tendon lengthening, a surgical procedure that involves cutting and lengthening the conjoint tendon in order to reduce tension and compression, is able to prevent or reduce the risk of anterior shoulder pain at one year after surgery.
