ABSTRACT
Objectives: The objective is to observe the functional outcome of early stages of osteoarthritis knee treated with Bone marrow aspirate concentrate (BMAC) and Intraarticular steroid A total of 60 Methods: patients of both genders aged 45–60 years were included in the study. 5ml - 10ml of Bone marrow was aspirated under local anaesthesia from iliac crest, ipsilateral / contralateral to the knee, with a bone marrow aspiration needle and was centrifuged and processed. 40 mg of Triamcinolone was mixed with BMAC and was administered in the knee joint. This procedure was done under Day Care. At 6-month follow-up, BMAC injection with 40 mg triamcinolone signi?cantly improved knee pain and Results: function. BMAC injection with 40 mg triamcinolone signi?cantly improved knee pain and function in early stages of Conclusion: osteoarthritis knee
ABSTRACT
Background: Osteoarthritis (OA) of the knee is a very common musculoskeletal disorder. Although total knee replacement is a suitable option in the treatment of severe OA, it has some limitations when performed in the early stage and early age. Bone marrow aspirate concentrate (BMAC), which is rich in mesenchymal stem cells, is promising due to its potentially regenerative and symptomatic effects in many disorders of the musculoskeletal system. This study aims to investigate the efficacy of BMAC in terms of functional recovery in OA of the knee joint.Methods: Total of 52 patients with unilateral symptomatic knee OA but no inflammatory disease, advanced malalignment or instability were enrolled in this study. Bone marrow aspirate was collected from the iliac crest in one session, prepared using a manufactured kit and the patients received intra-articular injections of this BMAC. The mean age of the patients was 59.2±7.4 and the mean follow-up period was 22.1±3.6 months. Functional outcomes of the patients were evaluated using Modified Cincinnati and Tegner Lysholm scoring systems.Results: It was observed that both Lysholm and Cincinnati scores of the patients were statistically significantly higher throughout the follow-up period as compared to the period before the procedure (p=0.0001). There was no statistically significant difference in Lysholm and Cincinnati ratings between gender, side and body mass index groups throughout the follow-up period (p >0.05). It was found that the results of the patients with Kellgren-Lawrence Grade 4 severe joint arthrosis were statistically significantly lower (p <0.05).Conclusions: Considering the functional outcomes of the patients up to two years, it was observed that the application of concentrated bone marrow aspirate provided functional recovery in arthrosis of the knee joint.
ABSTRACT
Bone marrow aspirates concentrate (BMAC) transplantation is a well-known technique for cartilage regeneration with good clinical outcomes for symptoms in patients with osteoarthritis (OA). Magnetic resonance imaging (MRI) has an important role in evaluating the degree of cartilage repair in cartilage regeneration therapy instead of a second assessment via an arthroscopy. We experienced a case of hypertrophic regeneration of the cartilage and a presumed simultaneous regeneration of the posterior horn of the lateral meniscus after BMAC transplantation for a cartilage defect at the lateral tibial and femoral condyle. This report provides the details of a case of an unusual treatment response after a BMAC transplant. This report is the first of its kind to demonstrate a MR image that displays the simultaneous regeneration of the cartilage and meniscus with a differentiation ability of the mesenchymal stem cell to the desired cell lineage.
