Does Suture Technique Affect Re-Rupture in Arthroscopic Rotator Cuff Repair? A Meta-analysis

Area of Science:

• Orthopedic surgery
• Sports medicine
• Biomedical engineering

Background:

• Rotator cuff tears are common injuries, often requiring surgical repair.
• The choice of suture technique and repair method may influence healing outcomes.
• Understanding factors affecting rotator cuff repair healing is crucial for optimizing patient recovery.

Purpose of the Study:

• To evaluate the impact of suture configuration, repair method, and tear size on rotator cuff repair healing.
• To compare rerupture rates across different suture types in single-row repairs.
• To assess rerupture rates for double-row anchor (DA) and suture bridge (SB) repairs.

Main Methods:

• Systematic review of 13 studies (Level IV evidence) published between 2003 and 2014.
• Analysis of 682 rotator cuff repairs, stratifying by tear size (<3 cm and ≥3 cm).
• Comparison of rerupture rates for simple, mattress, and modified Mason-Allen sutures in single-row repairs, and between DA and SB repairs.

Main Results:

• No significant difference in rerupture rates for different sutures in single-row repairs, irrespective of tear size (P > .18).
• No significant difference in rerupture rates between suture bridge (SB) and double-row anchor (DA) repairs for both small and large tears (P > .29).

Conclusions:

• Suture technique does not appear to significantly affect rerupture rates in single-row rotator cuff repairs.
• Double-row repair methods (DA and SB) showed no difference in rerupture rates.
• These findings suggest that suture technique may not be a critical factor in rotator cuff repair healing outcomes.
