- Brief Summary
Mesenchymal stem cells (MSC) are stromal cells that have the ability to self-renew and also exhibit multilineage differentiation. MSCs can be isolated from a variety of tissues, such as umbilical cord, bone marrow, and adipose tissue. The multipotent properties of MSCs make them a promising option for the treatment of osteoarthritis (OA).
Bone marrow mesenchymal stem cells (BM-MSC) and adipose derived mesenchymal stem cells (AD-MSC) have been used separately to treat OA. The aim of the present study will be to compare in a randomized non blind controlled clinical trial 3 types of intra-articular injections containing MSC populations obtained from two clinically relevant sources: BM-MSC, AD-MSC and a combination of both BM-MSC and AD-MSC.
- Detailed Description
The aim of the present study will be to compare 3 types of intra-articular injections of MSC populations obtained from two clinically relevant sources: injections containing BM-MSC or AD-MSC or a combination of both BM-MSC,and AD-MSC in a randomized non blind clinical trial.
To assess the efficacy and safety of 3 kind of MSC injections in relation to pain, function and quality of life in patients with knee OA.
A total of 54 patients with the diagnosis of knee OA grade II and III will be recruited to receive a single intra-articular injection of MSC: Group 1 (n 18 patients) will receive BM-MSC, Group 3 (n 18 patients) will receive AD-MSC. Group 3 (18 patients) will receive a combination of BM-MSC and AD-MSC.
A randomized non blind clinical trial with active control. For this purpose, the random number generator is 54, found on the RANDOM.ORG ® website (available at https://www.random.org/integers/)

- Primary Outcome Measures
Name Time Method knee pain assessed by Visual Analogue Scale. 12 months psychometric response scale which used in questionnaires. It is a measurement instrument for subjective characteristics of pain . Score from O to 10. O indicate no pain, and 10 indicate the worst pain.
knee function assessed by WOMAC (Wester Ontario McMaster Osteoarthritis Index). quosteionary. 12 months The Index contains 24 questions five items for pain (score range 0-20), two for stiffness (score range 0-8), and 17 for functional limitation (score range 0-68). Individual question responses are assigned a score of between 0 (extreme) and 4 (None). Individual question scores are then summed to form a raw score ranging from 0 (worst) to 96 (best). Finally, raw scores are normalized by multiplying each score by 100/96. This produces a reported WOMAC Score of between 0 (worst) to 100 (best).
- Secondary Outcome Measures
Name Time Method Quantitative T2-Mapping Evaluation of Changes in Cartilage Matrix 6 months after procedure MRI T2 mapping of the cartilage is a non-invasive functional imaging technique delivering cartography of the T2 relaxation time of the cartilage without any contrast injection. It is sensitive to tissue anisotropy, and provides compositional information on the cartilage collagen network, water content and proteoglycans concentration.
