| Abstract | We describe a single stage arthroscopic procedure for the treatment of articular cartilage defects in the knee. The novel procedure involves microfracture and application of bone marrow aspirate concentrate cells (BMAC) with hyaluronic acid and fibrin gel. The aim of the study was to evaluate the clinical and radiological outcomes at 2 years. A prospective study of 30 patients with symptomatic ICRS grade III/IV chondral defects, ranging from 2–9 cm$^{2}$, who were assessed clinically and radiologically. The surgical procedure involved debridement of the lesion, microfracture and application of concentrated BMAC with HA and fibrin gel under CO$_{2}$ insufflation. Patients underwent morphological MRI, quantitative T2*-mapping and d-GEMRIC scan. Clinical assessment used the Lysholm, IKDC and KOOS scores. Radiological assessment used the MOCART score. At 2 year follow-up, Lysholm score was 80.1, as compared to 50.8 pre-operatively (p < 0.05). KOOS (symptomatic) was 92.1, as compared to 65.7 pre-operatively. IKDC (subjective) was 83, up from 39 preoperatively. The mean T2* relaxation-times for the repair tissue and native cartilage were 29.1 and 29.9 respectively. Average MOCART score for all lesions was 72. Our technique shows encouraging clinical results at 2 year follow-up. Clinical outcome scores show significant benefit. The morphological MRI shows good cartilage defect filling and the biochemical MRI (T2*-mapping) suggests hyaline like repair tissue. |

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.
