Rotator Cuff Healing and Augmentation

Failure Rate in Rotator Cuff Repairs

Almost 1 in 5 people failed to heal their rotator cuff after primary repair. Studies show that 86% of rotator cuffs failed at the suture-tendon interface.

Factors influencing failure risk:

  • AP tear size
  • Tear retraction
  • Grade of infraspinatus fatty infiltration
  • Bone mineral density
  • Increasing age >70 years
  • Level of work activity

Kwon et al created a 15-point scoring index (RoHI) based on these patient risk factors to predict healing of the rotator cuff.

Benefits of Augmentation

Several studies show the use of graft augmentation in rotator cuff repairs may improve biomechanical strength and tendon healing, and increase healing rates.

Specifically, acellular dermal allograft may have the ability to vascularize and remodel into tendon-like tissue and increase the biomechanical strength of a rotator cuff repair by over 60%. Additionally, it may improve postoperative healing compared to standard repairs.

In large rotator cuff tears (>3 cm), postoperative healing rates increased to 85% with dermal augmentation, compared to 40% with a standard repair.
