Lower ACLR Failure Rates in Bone-Soft Tissue Versus Soft Tissue-Only Allografts in Adults: A Systematic Review and...

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Sports Medicine

Background:

• Allografts are frequently used for anterior cruciate ligament reconstruction (ACLR).
• Limited evidence exists to guide the optimal selection of allografts for ACLR.
• Graft choice significantly impacts patient outcomes and revision rates.

Purpose of the Study:

• To compare clinical and graft failure rates between soft tissue-only allografts and bone-soft tissue allografts in adult ACLR.
• To provide evidence-based guidance for allograft selection in ACLR.
• To analyze cumulative failure and graft rupture rates based on allograft type.

Main Methods:

• Systematic review and meta-analysis of English-language studies.
• Inclusion of primary and revision ACLR studies in adults using non-irradiated grafts.
• Data extraction on allograft type, patient characteristics, follow-up, and failure rates, with meta-analysis to pool outcomes.

Main Results:

• Fourteen studies were included, analyzing bone-soft tissue and soft tissue-only allografts.
• Bone-soft tissue allografts showed a significantly lower cumulative failure rate (11%) compared to soft tissue-only allografts (20%).
• Graft rupture rates were also lower for bone-soft tissue allografts (6%) versus soft tissue-only allografts (13%).

Conclusions:

• Bone-soft tissue allografts exhibit superior performance with lower cumulative failure rates than soft tissue-only allografts in ACLR.
• The findings suggest that bone-soft tissue allografts may be the preferred choice for anterior cruciate ligament reconstruction.
• Further research may explore long-term outcomes and specific patient factors influencing graft choice.
