present the specific reasons for delaminated rotator cuff tears are not
clear. However, the presence of delamination is reported to be
negatively associated with tendon healing and a negative prognostic
factor for functional rehabilitation after arthroscopic repair. No
consensus on understanding of the biomechanics and choosing of repair
methods for the delaminated rotator cuff tears have been achieved up to
now. The delaminated rotator cuff tear is mainly composed of superficial
bursal layer and the deeper articular layer. It has been demonstrated
that the articular layer is under greater stress than bursal layer
before delaminated rotator cuff repairs, and both the superficial and
deep layers in the delaminated cuff tears mainly retracted
posteromedially. Some studies showed that a synovial-like lining
presented between the delaminated rotator cuff, which should be removed
prior to repair. Currently, the diagnosis of delaminated rotator cuff
tears mainly comes from intraoperative exploration, and the treatment is
divided into arthroscopically assisted mini open rotator cuff repair
and total arthroscopic rotator cuff repair. However, there is no
consensus on whether en mass suture or separate double-layer suture.
Therefore, this paper summarizes the biomechanics, treatment and
research progress of delaminated rotator cuff tears.
