The Migratory Cortical Button: A Rare Case of Hypersensitivity to Titanium after an Anterior Cruciate Ligament Reconstruction.

Allergy to metal, especially to titanium, is a poorly known subject in orthopedic surgery and is mostly found after arthroplasty. Here, we describe an original case of titanium allergy that developed after an anterior cruciate ligament (ACL) reconstruction of the left knee in a patient with a history of severe atopic dermatitis. Three years after the surgery, he returned to the clinic with the femoral cortical button in his hand; he removed the device from the wound when the skin spontaneously opened at the lateral part of the thigh.

Incorporation of Hamstring Grafts Within the Tibial Tunnel After Anterior Cruciate Ligament Reconstruction: Magnetic Resonance Imaging of Suspensory Fixation Versus Interference Screws.

Background: The success of anterior cruciate ligament (ACL) reconstruction requires solid graft incorporation within the tunnels to enable graft remodeling. Resorbable interference screws (RIS) provide limited tendon-bone contact because much of the tunnel circumference is occupied by the screw itself, while adjustable suspensory fixation (ASF) systems provide larger contact zones, which favor ligamentization.

Purpose: To evaluate ligamentization of a 4-strand semitendinosus (4ST) graft fixed with ASF compared with RIS within the tibial bone tunnel at 6 months postoperatively using magnetic resonance imaging (MRI).

Endoscopic treatment of intrasheath peroneal tendon subluxation.

Intrasheath subluxation of the peroneal tendons within the peroneal groove is an uncommon problem. Open exploration combined with a peroneal groove-deepening procedure and retinacular reefing is the recommended treatment. This extensive lateral approach needs incision of the intact superior peroneal retinaculum and repair afterwards.

Endoscopic calcaneoplasty combined with Achilles tendon repair.

Endoscopic calcaneoplasty is a minimally invasive technique for resection of inflamed retrocalcaneal bursa as well as the posterosuperior part of the calcaneus. A relative contra-indication for this technique is a tear of the Achilles tendon. In this report, we describe the treatment of a patient with Haglund's deformity associated with a tear of the Achilles tendon.

Two-bundle, four-tunnel anterior cruciate ligament reconstruction.

We reviewed 33 patients who underwent anterior cruciate ligament (ACL) reconstruction using a two-bundle, four-tunnel technique. The posterolateral bundle (PLB) and anteromedial bundle (AMB) were individually reconstructed with gracilis and semitendinosus tendon auto-grafts, respectively, using separate tibial and femoral tunnels. At final follow-up (24 months post surgery, range 18-31) the International Knee Documentation Committee's (IKDC) objective final evaluation scores were 69 A, 19 B, 12% C.
