The knee is the largest joint in the body and also having healthy and balanced knees is called for to execute most everyday activities.
The knee is made up of the lower end of the thighbone (thigh), the top end of the shinbone (tibia), and the kneecap (knee). The ends of these three bones are covered with articular cartilage material, a smooth material that safeguards the bones and also allows them to move conveniently within the joint.
The curves lie between the thigh and shin. These C-shaped wedges work as “shock absorbers” that support the joint.
Huge ligaments hold the femur and also shin with each other as well as supply stability. The lengthy upper leg muscles provide the knee stamina.
All staying surface areas of the knee are covered by a slim cellular lining called the synovial membrane layer. This membrane layer releases a liquid that lubes the cartilage, lowering friction to almost zero in a healthy and balanced knee.
Generally, every one of these elements work in consistency. Yet condition or injury can interrupt this consistency, resulting in discomfort, muscle weakness, as well as decreased feature.
One of the most usual source of persistent knee discomfort as well as impairment is joint inflammation. Although there are lots of types of arthritis, the majority of knee discomfort is caused by simply three kinds: osteo arthritis, rheumatoid joint inflammation, and also post-traumatic joint inflammation.
Osteoarthritis. This is an age-related “wear and tear” sort of joint inflammation. It typically occurs in people half a century of age and older, yet might happen in younger people, as well. The cartilage that cushions the bones of the knee softens and also wears away. The bones then scrub against each other, creating knee pain and also tightness.
A total knee replacement (also called knee arthroplasty) may be more accurately called a knee “resurfacing” because just the surface area of the bones are changed.
Prepare the bone. The damaged cartilage material surfaces at the ends of the thigh as well as tibia are removed along with a small amount of underlying bone.
Placement the metal implants. The eliminated cartilage material and also bone is replaced with steel elements that recreate the surface area of the joint. These metal components may be cemented or “press-fit” right into the bone.
Resurface the patella. The undersurface of the patella (kneecap) is cut and resurfaced with a plastic switch. Some doctors do not resurface the knee, relying on the situation.
Put a spacer. A medical-grade plastic spacer is placed in between the steel parts to develop a smooth sliding surface area.
