Ultrasound for Treating Meniscocapsular Separation Together With Arthroscopy

Area of Science:

• Orthopedic Surgery
• Diagnostic Imaging
• Sports Medicine

Background:

• Magnetic resonance imaging (MRI) is standard for meniscal tear diagnosis.
• Medial meniscal tears, particularly meniscocapsular separation, present diagnostic challenges for MRI.
• Accurate diagnosis is crucial for effective surgical intervention and patient outcomes.

Purpose of the Study:

• To present a technical note on the intrasurgical use of ultrasonography for diagnosing meniscocapsular separation.
• To demonstrate ultrasonography's utility in confirming the stability of meniscal tears post-suturing.
• To highlight a case where ultrasonography provided a preoperative diagnosis missed by MRI.

Main Methods:

• Intrasurgical ultrasonography was employed for real-time diagnosis during arthroscopic surgery.
• Ultrasonography identified meniscocapsular separation as a distinct vertical, low echoic area.
• A picture-in-picture function integrated ultrasonography with arthroscopic visualization.

Main Results:

• Ultrasonography successfully detected meniscocapsular separation in a case where MRI was inconclusive.
• The technique allowed for intraoperative confirmation of the beneficial effect of suturing on lesion stability.
• Ultrasonography proved to be an effective tool for diagnosing this specific meniscal injury.

Conclusions:

• Intrasurgical ultrasonography is a valuable tool for diagnosing medial meniscal meniscocapsular separation.
• Ultrasonography enhances arthroscopic surgery by providing real-time diagnostic information and treatment confirmation.
• This imaging modality offers a complementary approach to MRI for complex meniscal pathologies.
