How do torn ligaments heal?
Ligaments heal through a distinct sequence of cellular events that occur through three consecutive phases: the acute inflammatory phase, the proliferative or regenerative phase, and the tissue remodeling phase. Ligament healing is often slow and incomplete.
Why do ligaments heal slowly?
Ligaments attach bones to other bones. They generally have a more limited blood supply than either muscle or tendon – lengthening their healing time.
Is it worse to tear a ligament or a tendon?
Because tendons have better blood supply than ligaments, tendon injuries tend to heal faster than ligament injuries of comparable severity. Both ligament tears and tendon tears are serious conditions that can cause intense pain and irreversible impairment if left untreated.

Can ligament injuries be prevented?
Not all ligament injuries can be prevented, but you can take steps to keep your ligaments safer, especially during exercise:
What are ligaments made of?
Ligaments are much more complex, being composed of cells called fibroblasts which are surrounded by matrix. The cells are responsible for matrix synthesis and they are relatively few in number and represent a small percentage of the total ligament volume. Although these cells may appear physically and functionally isolated, recent studies have indicated that normal ligament cells may communicate by means of prominent cytoplasmic extensions that extend for long distances and connect to cytoplasmic extensions from adjacent cells, thus forming an elaborate 3-dimensional architecture.
Which joint has ligaments?
The image shows the shoulder joint, which has many ligaments. Ligaments are specialized connective tissues with very interesting biomechanical properties. The basic building blocks of a ligament are collagenfibers. These fibers are very strong, flexible, and resistant to damage from pulling or compressing stresses.
What is the microstructure of a ligament?
Ligament microstructure can be visualized using polarized light that reveals collagen bundles aligned along the long axis of the ligament and displaying an underlying "waviness" or crimp along the length. Crimp is thought to play a biomechanical role relating to the ligaments loading state with increased loading resulting in some areas of the ligament uncrimping, allowing the ligament to elongate without sustaining damage.
How do ligaments heal?
Ligaments heal by a process which includes three phases: 1 Hemorrhage with inflammation - involves retraction of the disrupted ligament ends, formation of a blood clot, which is subsequently resorbed, and replaced with a heavy cellular infiltrate. Subsequently, a considerable hypertrophic vascular response takes place in the gap between the disrupted ends and results in an increase in both vascularity and blood flow, both of which decrease with time. 2 Matrix and cellular proliferation - defined as the production of "scar tissue" (dense, cellular, collagenous connective tissue matrix) by hypertrophic fibroblastic cells. This scar tissue is initially quite disorganized with more defects. After a few weeks of healing, the collagen becomes quite well aligned with the long axis of the ligament despite the fact that the types of collagen are abnormal and the collagen fibrils have smaller diameters in the proliferating tissue. 3 Remodeling and maturation (matrix remodeling) - defects in the scar become filled in but although the matrix becomes more ligament-like with time, some major differences in composition, architecture and function persist. Differences which persist include altered proteoglycan and collagen types, failure of collagen crosslinks to mature, persistence of small collagen fibril diameters, altered cell connections, increased vascularity, abnormal innervation, increased cellularity and the incomplete resolution of matrix "flaws"[3]
What happens when you remove the epiligament?
Removal of the epiligament exposes the fibrous architecture of the ligament which is further organized hierarchically into groups of parallel fibres known as bundles that are difficult to separate suggesting that they are interconnected in some fashion.
What is the function of ligaments?
Ligaments can be found connecting most of the bones in the body. The function of a ligament is to provide a passive limit to amount of movement between your bones.
