Postoperative Infection After Anterior Cruciate Ligament Reconstruction.

Context: Infection after anterior cruciate ligament reconstruction (ACLR) is uncommon; if it occurs, it can lead to disastrous complications.

Objective: To analyze post-ACLR infections and identify related complications to provide the most effective treatment protocol.

Study Design: Clinical review.

Matrix-Induced Autologous Chondrocyte Implantation versus Multipotent Stem Cells for the Treatment of Large Patellofemoral Chondral Lesions: A Nonrandomized Prospective Trial.

Objective: To compare the outcome of matrix-induced autologous chondrocyte implantation (MACI) and bone marrow aspirate concentrate (BMAC)-derived multipotent stem cells (MSCs) implantation in patellofemoral chondral lesions, using the same HYAFF11 scaffold.

Methods: From January 2005 to December 2010, 37 patients with patellofemoral chondral lesions were prospectively followed up, for a minimum of 3 years; 19 of these patients were treated with MACI and 18 with BMAC. Radiographs, magnetic resonance imaging, and clinical scores (International Knee Documentation Committee, Knee Injury and Osteoarthritis Outcome Score, visual analog scale, and Tegner) were collected preoperatively, at 2-year and final follow-up.
