- Degenerative arthritis is a disease in which local degenerative changes occur as the articular cartilage wears down, also called osteoarthritis or osteoarthritis.
- Degenerative arthritis is a type of chronic arthritis, a disease caused by overgrowth of bones in the joint surface due to degenerative changes in the joint cartilage under heavy weight load, and appearing in middle-aged adults. The disease is first, the cartilage cells that make up the cartilage composition components are degraded due to aging, the cartilage loses its elasticity. Then, as time passes, the surface of the cartilage becomes rough, and various kinds of substances enter the inside of the joint cavity, which is wrapped in the joint membrane, thereby causing inflammation. Clinically, recurrent pain, joint stiffness, and gradual dyskinesia of the joints are present.
- the causes of degenerative arthritis are deeply related to aging and excessive weight, and the more and more severely in women as they age.
- Early symptoms include one or two joints with stiff pain, such as stiffness, prolonged prolongation of the cartilage, hardening of the subchondral bone, hyperplasia of the bone around the joint, and deformation of the joint.

- the mixture was centrifuged at 1000 rpm for 5 minutes at 4 ° C., and then the physiological saline supernatant was removed to obtain an MCCM / SVF mixture.
- the MCCM / SVF mixture was mixed with 1 ml of aprotinin solution mixed with fibrinogen using a mix syringe.
- Example 1 MCCM 10 mg
- Example 2 MCCM 10 mg
- the viability of chondrocytes and differentiation into chondrocytes was the most active. That is, when the content of MCCM is too large, it is determined that the differentiation into chondrocytes is slow because there is less space for differentiation into chondrocytes.
- Figure 6 shows the animal experiment process for checking whether the cartilage regeneration. Specifically, animal experiments for confirming whether cartilage regeneration was performed as follows.
- the obtained SVF (10 5 to 10 7 ) was mixed with physiological saline in which 10 mg of the prepared glass cartilage powder (MCCM) was dispersed.
