Fixation of the knee joint with a needle

It is not easy to find a free bone-cartilaginous body in the cavity of the knee joint. Quite often, especially for a novice surgeon, the search for a "joint mouse" turns into a complex operation. In 5 patients, we used an injection needle to fix the free bone body found during the operation. Patients usually themselves, sitting on the operating table, grope for the "articular mouse" and try to hold it. After processing the operating field, the surgeon's assistant fixes the "articular mouse" with his fingers, and then pierces the body with a needle through the skin and the capsule of the joint and holds it. The surgeon makes an incision and, grasping the free body with a clamp, removes it. In this case, the incision of the skin and the joint capsule is no more than 5 cm, which is important for a favorable course of the postoperative period. We did not find information on the use of this technique for fixing a free body in the knee joint in the available literature.
