| Abstract | The anterior cruciate ligament (ACL) is critical for knee stability when walking or running. Unfortunately, it does not heal well after significant tearing or rupture and surgery is often necessary to reconstruct the injured ligament. Though ACL ruptures are quite common, the surgical repair of this ligament has inconsistent success rates [1]. The goal of this study was to characterize a biomimetic tissue engineered ACL scaffold using a novel combination braid-twist technique. The braid-twist scaffolds were made using the following procedure: • Nine groups of six 160 mm length PLLA fibers were selected. • Each group of six fibers was twisted in a counter-clockwise manner to form a fiber bundle (a total of nine fiber bundles/scaffold). • Three of these bundles were twisted around one another counter-clockwise to form a yarn (a total of three yarns/scaffold). • These three yarns were braided together to form one scaffold. This technique is based on the structure of ACL tissue and is designed to reduce scaffold fatigue and accurately mimic ACL behavior. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
