Tendon ornithischian dinosaurs, ossified axial muscle tendons form a latticework along the neural and haemal spines on the tail, presumably for support. Tendon A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to bone, while tendons connect muscle to bone for a proper functioning of the body. Histologically, tendons consist of dense regular connective tissue fascicles encased in dense irregular connective tissue sheaths. Normal healthy tendons are composed mostly of parallel arrays
Patellar tendon rupture weakness after the injury and repair. If the tendon rupture is a partial tear (without the two parts of the tendon being separated) then non-surgical methods of treatment may suffice. The future of non-surgical care for partial patella tendon ruptures is likely bioengineering. Ligament reconstruction is possible using mesenchymal stem cells and a silk scaffold. These same stem cells have been shown to be capable of seeding repair of damaged animal tendons. In 2010, a clinical study proved that mechanical loading of the tendon callus during the remodelling phase leads to healing by regeneration. Patellar tendon rupture Patellar tendon rupture
