Summary: Recent studies on animal models suggested that nanofractures showed advantages in biomechanical, histological, and radiographic results compared to larger diameter microfractures; the aim of our study was to evaluate the clinical efficacy of biologic enhancement of tendon bone-healing through nanofractures of the greater tuberosity.


Background

Although it has been shown that microfractures of the greater tuberosity reduce re-tear rate after arthroscopic rotator cuff repair, recent studies on animal models suggested that nanofractures showed advantages in biomechanical, histological, and radiographic results compared to larger diameter microfractures.

Methods

A retrospective study was conducted. Patients who underwent an arthroscopic rotator cuff repair associated with nanofractures of the greater tuberosity instead of cortical abrasion were included. Exclusion criteria were: partial thickness tears, irreparable tears, capsulo-labral pathologies, calcific tendonitis, gleno-humeral osteoarthritis and/or previous surgery. Primary outcome was the ASES score. Secondary outcomes were: Quick-DASH, WORC and evaluation of tendon integrity through a magnetic resonance imaging (MRI) performed six months after surgery. A paired t-test was used to compare pre and postoperative outcomes. A subgroup analysis for tear size was also conducted. Significance was set at p < 0.05.

Results

The study included 20 males and 9 females. Mean age (+ SD) of patients was 61 + 6.9 years. Mean follow-up was 31.5 + 10.9. Comparison between pre- and postoperative functional scores showed significant clinical improvement (p < 0.001). Subgroup analysis for tear size showed no differences nor in functional outcomes, neither in structural integrity. Postoperative imaging showed healed tendons in 25 out of 29 (86.2%) MRI.

Conclusions

Nanofractures of the greater tuberosity enhances functional and structural outcome after rotator cuff repair.
