Tunnel Widening in Revision Anterior Cruciate Ligament Reconstruction

Widening of the tibial and femoral tunnels can present a substantial obstacleduring revision anterior cruciate ligament reconstruction because of the associatedbone loss and poor graft fixation. Delayed incorporation of soft-tissue graftsinto bone and decreased graft stability are of particular concern. The degreeto which mechanical (eg, graft position, fixation method) and biologic (eg,increased cytokine levels, synovial fluid propagation) factors contributeto tunnel widening remains unclear. Radiography, CT, and MRI can be used tocharacterize the extent of widening and aid in preoperative planning. Althoughmany management methods exist, revision surgery remains difficult. Controversypersists regarding the clinical significance, contributing factors, prophylacticmeasures, and effective management of tunnel widening following anterior cruciateligament reconstruction.

Return to sports likely even with traumatic type II lesions

Arthroscopic SLAP repair yields mostly favorable outcomes

Although most patients with type II superior labral anterior posterior (SLAP) lesions who are treated arthroscopically can expect good results, athletes with a distinct traumatic etiology have a significantly greater likelihood of a successful return to sports, said the authors of a study presented at the AAOS 75th Annual Meeting.

Preparation and Use of Antibiotic-Impregnated Beads for Orthopaedic Infections

Localized antibiotic therapy using antibiotic-impregnated bone cement has become an attractive option for treating severe orthopaedic infections. In the form of beads and spacers, antibiotic-impregnated cement can provide high concentrations of local antibiotic to a wound with minimal systemic toxic exposure. Clinical uses of antibiotic beads and spacers include prophylaxis for open fractures and total joint arthroplasties and in the treatment of acute and chronic osteomyelitis. Limited clinical data indicate that the use of antibiotic beads decreases the incidence of adverse effects observed with systemic antibacterial therapy. A detailed description of the"bead pouch"technique for the prevention of infection in open fractures is provided in this article.
