Total Knee Replacement

Total Knee Replacement (TKR) surgery  is a one and a half to three hour, inpatient surgical procedure in which an knee joint is replaced with a prosthetic knee joint. A TKR surgery may be recommended for patients with arthritis or severe degeneration of and damage to the bone and cartilage in the knee. TKR will relieve patients of arthritic pain, and will preserve the patient’s range of motion of the joint.  Dr. Craig S. Radnay practices conservative medical care, meaning non-surgical methods of treatment will be explored thoroughly before surgery is recommended.

The TKR Procedure involves removing the damaged knee cartilage and bone, and shaping the area to fit the prosthetic joint, lasting 10 to 20 years.  This procedure has a extremely high success rate of ninety-percent.  However, as with all major surgical procedures, there are risks of complications during and after surgery.  These complications include:

  • Clots that may travel to the lungs
  • Infection
  • Prosthesis failure
  • Nerve damage
  • Urinary Tract Infections
  • Fractures near the site of the prosthetic joint (more of a risk for elderly individuals)

Ideal candidates for this type of procedure are individuals who are of healthy weight.  Patients who do not meet these requirements may increase the risk of complications.  Even if a candidate were to meet these requirements, a major surgery may not be the recommended treatment. Dr. Craig S. Radnay practices conservative medical care, meaning non-surgical methods of treatment will be explored thoroughly before surgery is recommended.

Patients can expect to be restricted to non-weight bearing use of crutches or a walker for the first 3 to 4 weeks.  The next two weeks, the patient should still be using the appropriate assisted device, bearing minimal weight on the knee.  The patient should finally be able to walk without any assistance after about one to two months.  Until the patient is able to walk, he or she should refrain from driving or operating any motor vehicle.  Lastly, it is vital for patients to follow physical therapy and exercise instructions in order to obtain a successful outcome.
