Risk Factors for Failure of Meniscal Repair

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Sports Medicine

Background:

• Meniscal preservation is crucial for knee function, load transmission, and joint stability.
• Expanding indications for meniscal repair necessitate understanding failure factors.
• Meniscal repair offers superior long-term outcomes compared to meniscectomy.

Purpose of the Study:

• Synthesize evidence on risk factors for meniscal repair failure.
• Clarify definitions and evaluation methods for meniscal repair failure.
• Outline management strategies for failed meniscal repairs.

Main Methods:

• Comprehensive review of contemporary literature on meniscal repair outcomes.
• Analysis of patient-related, tear-related, and surgical factors influencing failure.
• Evaluation of current diagnostic and management approaches for failed repairs.

Main Results:

• Meniscal repair failure is multifactorial, influenced by smoking, alignment, comorbidities, tear characteristics, and surgical variables.
• Advances in devices, imaging, and biologics enhance healing potential.
• Revision meniscal repair is effective in select patients with favorable tissue and tear morphology.

Conclusions:

• Successful meniscal repair hinges on appropriate patient selection, tear assessment, optimal repair strategy, and rehabilitation.
• Meniscal repair failure is not solely due to surgical technique.
• Revision repair is a viable option for preserving meniscal function; future research should standardize failure definitions and compare techniques.
