NCT03068988

Brief Summary

The prospective randomized clinical study investigating the effect of mesenchymal stem cells on tendon healing. The objective of the study is to demonstrate the effect of concentrated bone marrow stem cells ( MSCs ) to the healing of sutured tendon of the supraspinatus muscle in comparison to the same procedure performed without MSCs. We have postulated the hypothesis that MSCs enhance the healing of the sutured supraspinatus tendon to its humeral footprint.

Outcome Measures

Primary Outcomes (1)

  • The supraspinatus tendon re-rupture rate

    presence of the supraspinatus tendon rupture on magnetic resonance imaging evaluated 2 years after the surgery, incidence of rerupture compared between group I- with the use of mesenchymal stem cells and group II- without the use of mesenchymal stem cells

    2 years postoperatively

Secondary Outcomes (3)

  • visual analogue scale

    1 day before the surgery, 6 months postoperatively, 1 year postoperatively, 2 years postoperatively, 5 years postoperatively, 10 years postoperatively

  • ASES score- American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form

    1 day before the surgery, 6 months postoperatively, 1 year postoperatively, 2 years postoperatively, 5 years postoperatively, 10 years postoperatively

  • Constant score

    1 day before the surgery, 6 months postoperatively, 1 year postoperatively, 2 years postoperatively, 5 years postoperatively, 10 years postoperatively
