Joint replacement

Joints are connections between two or more bones that enable different kinds of movement. But did you know that there are true joints and so-called ‘false’ joints?

True joints have a space between the ends of the bones. This joint space is located in a joint cavity, which is surrounded by a joint capsule. The ends of the bones are covered in articular cartilage and ligaments help to guide the movements of the joint. True joints give us mobility.

False joints, in contrast, tend to be stiff and provide stability. So they are built differently to true joints:

  • Some are fibrous joints, such as the connection between the shin bone and the calf bone, which are joined by a dense connective tissue.
  • The spinal discs are an example of cartilaginous joints. As the name suggests, these joints are joined by various types of cartilage tissue.
  • And bony joints are joints like the sacrum and the coccyx (tailbone) – these two vertebrae are actually fused together

Joint replacement surgery is one of the last line of treatment when all other treatment options such as physical therapy and medication, have been exhausted. Joint pain, joint deformation and movement restriction issues are effectively corrected through joint replacement surgery.  

Who benefits from joint replacement surgery?

Joint replacement surgery is often recommended to patients who are suffering from severe joint pain/ stiffness, swelling/ inflammation, muscles weakness, and restriction movement. Because of these conditions, patients are not able to perform their daily activities such as walking, taking stairs, putting on shoes etc.
