Knee Replacement

Dr. Hope believes that a knowledgeable patient will make the best decision about his or her own treatment.

With him, you will discuss how your condition developed and how various treatment approaches can improve or repair the problem. After treatment alternatives are considered, Dr. Hope will present a realistic outlook on the results that can be achieved. He will be frank about any risks that might be involved. Non-surgical options, if available, will be explained in depth.

Knee Replacement

A surgical procedure to replace the weight-bearing surfaces of the knee joint.

It is most commonly performed for osteoarthritis,and also for other knee diseases such as rheumatoid and psoriatic arthritis; it helps relieve pain and disability in the patient's knee. The recovery period can be 6 weeks or longer.

Minimally Invasive Computer-assisted Subvastus Knee Surgery

The minimally invasive (MI) computer-assisted (CAS) subvastus knee replacement is performed by replacing lost cartilage and diseased bone without making incision in the quadriceps muscle and tendon. It is performed with computer assistance, so that a guide rod doesn't have to be inserted into the femoral bone – allowing for more precise positioning of the component.

Minimally invasive computer-assisted subvastus knee surgery reduces post operative pain by sparing the quadriceps muscle and tendon that are cut through during traditional total knee replacement surgery. Surgeons make a small incision that will move the soft tissue rather than cutting through it. A computer-assisted technique is used so the surgeon can perform the procedure without inserting a guide rod into the femoral bone. The computer gives the surgeon immediate feedback during the procedure so that the patient has the best possible knee alignment.

To perform the surgery, the surgeon makes a 6-8 inch incision in the front of the patient's knee. The damaged surfaces of the knee are removed and the ends of the bones are reshaped to allow immediate weight bearing. Once the surgeon has completed this procedure, the incision is then closed and a bandage is applied. The surgery usually takes between 45-90 minutes.

Benefits of the MI CAS Subvastus Total Knee Replacement

  • Less trauma to muscles and tendons. The quadriceps tendon and muscle are avoided rather than cut through
  • Performed without inserting a guide rod into the femoral bone
  • Less damage to tissue
  • Shorter rehabilitation
  • Less blood loss
  • Shorter hospital stay
  • Faster return of basic knee functions
