Use of Platelet-Leukocyte Membrane in Arthroscopic Repair of Large Rotator Cuff Tears

Abstract

The use of the platelet-leukocyte membrane in the treatment of rotator cuff tears improved repair integrity compared with repair without membrane. However, the improvement in repair integrity was not associated with greater improvement in the functional outcome. In fact, the Constant scores of the two groups would have been similar if the shoulder pain component (which had differed preoperatively) had been excluded.
