Patch augmentation with acellular dermal matrix allograft effectively reduced rotator cuff retear rates in high-risk patients (Rotator Cuff Healing Index score ≥7). Short-term clinical outcomes remained comparable to arthroscopic rotator cuff repair alone.

Area of Science:

  • Orthopedic Surgery
  • Regenerative Medicine
  • Biomaterials

Background:

  • Rotator cuff tears are common, leading to pain and dysfunction.
  • Arthroscopic rotator cuff repair (ARCR) is a standard treatment.
  • Patch augmentation aims to improve healing and reduce retear rates.

Purpose of the Study:

  • To compare retear rates and short-term clinical outcomes between ARCR and ARCR with patch augmentation (PA).
  • To evaluate the efficacy of PA using acellular dermal matrix allograft based on the Rotator Cuff Healing Index (RoHI).
  • To identify optimal indications for PA in rotator cuff repair.

Main Methods:

  • Retrospective case-control study of 738 patients (≥50 years) undergoing primary ARCR (2017-2023).
  • Patients stratified by RoHI score into ARCR alone and ARCR with PA groups.

  • Comparison of cumulative retear rates and clinical outcomes (ROM, ASES, Constant scores) at ≥12 months follow-up.

    • Main Results:

    • The RoHI demonstrated fair predictive performance for retears, with an optimal cutoff score of 7.
    • Patients with RoHI ≥7 showed significantly lower retear rates with PA compared to ARCR alone (21.6% vs 36.6%).
    • No significant differences in range of motion or clinical outcome scores (ASES, Constant) between groups; similar rates of achieving minimal clinically important difference.

    Conclusions:

    • Patch augmentation with acellular dermal matrix allograft effectively reduces retear rates in high-risk patients (RoHI ≥7).
    • PA is beneficial regardless of sex for reducing retears in this cohort.
    • Short-term clinical outcomes are comparable between ARCR with PA and ARCR alone.
