Decellularized tendon patch enhance biological and mechanical healing of large-to-massive rotator cuff tear in a rat chronic model: a comparison study of patch sterilization and storage methods.

Background: Large-to-massive rotator cuff tears (L-M RCTs) usually requires a patch to reconstruction. Decellularized tendon patch (DTP) was a biomimetic and effective material for reconstructing L-M RCTs. However, the protocol for DTP sterilization and storage is variable, which may influence their performance.
