Knee Replacement

Understanding A Knee Replacement

 

A knee replacement is a surgical procedure that can provide significant pain relief and improved function for people with advanced knee arthritis.  A knee replacement is typically performed after conservative options are tried including oral medications, injections, physical therapy and sometimes bracing.  It is a surgical procedure done through a single incision where the end of the thigh bone (femur), shin bone (tibia), and kneecap (patella) are resurfaced with metal and plastic. Patient may go home the day of surgery or spend 1 or 2 nights in the hospital.  There is typically a 3 to 6-month recovery before returning to full function.

Moderate Arthritis

  •  Bone spurs
  • Slight narrowing of joint

Advance Arthritis

  • Bone on bone with loss of cartilage
  • Malalignment
  • Large bone spurs

Knee Replacement

  • Provides improved function and significant pain relief.

 

Understanding arthritis:

 

Arthritis is a process where the normal tissue lining the knee joint starts to breakdown as a result of prolonged use, excessive stress, genetics, infection, trauma or other causes.  It is an inflammatory process with characteristic findings seen on x-ray.  Initially, the space between the bones which is filled by cartilage starts to narrow and bone spurs formed.  Over time the bone spurs worsen and the cartilage wears away completely.  Eventually this leads to malalignment of the leg.
