Does dynamically tensioning suture alter outcomes after rotator cuff repair?

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Musculoskeletal Research

Background:

• Dynamic tensioning sutures represent an advancement over traditional static sutures for tendon repair.
• Rotator cuff repair (RCR) is a common orthopedic procedure.
• Patient-reported outcomes (PROs) are crucial for evaluating surgical success.

Purpose of the Study:

• To compare patient-reported outcomes (PROs) following rotator cuff repair (RCR) using dynamic versus static tensioning sutures.
• To evaluate the efficacy of dynamic suture technology in RCR.

Main Methods:

• Retrospective review of 424 patients undergoing RCR by a single surgeon (2016-2022).
• Comparison of pre- and post-operative PROs (ASES, VAS, SSV) at a minimum of 2 years.
• Multivariable regression analysis controlling for preoperative variables and intraoperative findings.

Main Results:

• No significant preoperative differences between dynamic and static suture groups, except for acromial undersurface characteristics.
• Postoperative PROs (ASES, VAS, SSV) showed no significant differences between the two groups.
• Preoperative ASES, VAS, and tear size were independently associated with postoperative scores.

Conclusions:

• Dynamic tensioning sutures do not yield superior patient-reported outcomes compared to static sutures in arthroscopic rotator cuff repair.
• The choice between dynamic and static sutures may not significantly impact patient satisfaction or pain levels post-RCR.
