Abstract: A device for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions using intra articular localization has a guide, a locating arm, a set of attachment assemblies and a tubular sleeve. The device comprises a device body and an attachment assembly mounted on the device body. The attachment assembly includes a main body and at least one closure body. The main body has an elongated recess therein. The elongated recess is configured for receiving an elongated member therein along an entire length thereof. The at least one closure body is rotatably mounted on the main body. The elongated member may be positioned within the elongated recess via lateral movement when the at least one closure body is in a first rotational position relative to the main body.
