Summary Introduction

To determine:

The way composition of joints explains that joint injuries are slow to heal.

Introduction:

Joints such as shoulder, elbow, and knee are composed of considerable amounts of cartilage and dense regular connective tissue. The dense regular connective tissues are composed of closely packed collagen fibers, elastic fiber, and fibroblast cells.

On the other hand, the cartilages are rigid connective tissues with an abundant extracellular matrix. They are composed of collagen fibers embedded in a gel-like ground substance. The injuries of joints take a considerable amount of time to heal.
