  • Title: Intra-articular loose body removal during hip arthroscopy.
    Author: Randelli F, Randelli P, Banci L, Arrigoni P.

    Abstract:
    Loose bodies are common findings in hip arthroscopy. Loose body removal can be challenging because of the inner position of the acetabulum in which the loose bodies tend to accumulate. Moreover, the standard removal procedure of a considerable number of loose bodies may need a long time under limb traction, thereby increasing the risk of complications. This article describes a new easy method for intra-articular loose body removal. A flexible endotracheal catheter, connected with suction system, is inserted via the anterior or midanterior portal. The catheter can easily be directed toward the inner parts of the joint in proximity of loose bodies. The suction system allows the loose body to be captured in contact with the tip of the catheter, which is then retrieved carrying the loose body outside the cannula. We performed this technique on 4 consecutive patients with synovial chondromatosis. Patients were evaluated preoperatively and 1 month postoperatively by completing self-administered questionnaires. The technique effectiveness was evaluated in terms of overall surgery time, traction time, radiographic appearance of loose bodies left in situ, and postoperative complications. Mean overall surgery time and central time was 175 and 78 minutes, respectively. All patients showed improvement in the operated hip. All radiographs showed hip joint space free of osteochondral loose bodies. No patients reported paraesthesia, nerve palsy, or other postoperative complications. This technique allows for retrieval of a greater amount of loose bodies in a short time, reducing the possibility of undesirable complications.
