Biologic replacement for fibrin clot
View Patent ↗The invention provides compositions and methods for repairing intra-articular and extra-articular tissue including ligament, meniscus, cartilage, tendon, and bone. The method includes contacting the ends of an injured tissue from a patient with a composition. The repair composition includes soluble type 1 collagen, a platelet, and at least one of an extracellular protein and a neutralizing agent.
1. A method of treating an intra-articular injury by an arthroscopic procedure in a subject, the method comprising: contacting the ends of a ruptured intra-articular tissue having an intrasynovial environment from the subject with a composition comprising soluble type I collagen, a platelet, and at least one of an extracellular matrix protein and a neutralizing agent.
2. The method of claim 1 , wherein the intra-articular injury is a meniscal tear, ligament tear or a cartilage lesion.
3. The method of claim 1 , further comprising mechanically joining the ends of the ruptured tissue.
4. The method of claim 1 , wherein the extracellular matrix protein is selected from the group consisting of elastin, laminin, fibronectin, and entectin.
5. The method of claim 1 , further comprising a gene therapy agent.
6. The method of claim 5 , wherein the gene therapy agent includes a genetically altered cell.
