Ultrasound for Treating Meniscocapsular Separation Together With Arthroscopy.

Abstract

Magnetic resonance imaging (MRI) can be used to identify most types of meniscal tears; however, meniscocapsular separation of the medial meniscus can be difficult to identify with MRI. Here we present a technical note on the intrasurgical use of ultrasonography for the detection of meniscocapsular separation and confirmation of the beneficial effect of suturing on the stability of this lesion in a representative case of meniscocapsular separation that could be diagnosed with ultrasonography but not MRI preoperatively. Ultrasonography can detect meniscocapsular separation as a vertical low echoic area and be performed together with arthroscopy using the picture-in-picture function of the ultrasonography machine. Ultrasonography is an effective tool for diagnosing meniscocapsular separation and is helpful during arthroscopic surgery.
