Research in diverse fields such as biomaterials, stem cell biology, molecular biology, tissue engineering, and genetics have also provided further insight relevant to orthopaedic tissues. This review will synthesize major developments over the past year in the areas of cartilage injury and repair, meniscal injury, tendon and ligament pathology, muscle injury, tissue engineering and stem cell approaches to soft-tissue repair, and spine pathology.
