Over the past few years, many biologic patches have been developed to augment repairs of
large or complex tendon tears. These patches include both allograft and xenografts …

PURPOSE: This study tested a bone-tendon allograft versus human dermis patch for
reconstructing chronic rotator cuff repair by use of a canine model. METHODS: Mature …

Rotator cuff injuries are common in both young and elderly patients. Despite improvements
in instrumentation and surgical techniques, the failure rates following tendon reconstruction …

Background The quality of tendons has considerable limitations regarding torn rotator cuff
tendons. Tissue-engineering techniques using a biodegradable scaffold offer potential …

Understanding the cellular response to a biologic graft used in rotator cuff applications is
important because foreign-body reactions and inflammation complications have historically …

Purpose: The purpose of this study was to determine the load to failure strengths and modes
of failure of various commercially available tendon augmentation xenografts and allografts …

Materials and Methods An Institutional Review Board approval was available for this study
(RC-5047). A retrospective chart review of patients who had rotator cuff repair with acellular …

Porcine dermal collagen (Zimmer Patch, formerly known as Permacol; Tissue Science
Laboratories plc, Aldershot, Hampshire, UK) has been used for reinforcement of several …

Background Tears of the rotator cuff are one of the most common tendon disorders.
Treatment often includes surgical repair, but the rate of failure to gain or maintain healing …

Background: Large rotator cuff tears still represent a challenging problem in orthopaedics.
The use of tenocytes on biomaterials/scaffolds for the repair of large rotator cuff defects …
