Total Knee Replacement

Total Knee Replacement

When you run out of treatment options for your knee osteoarthritis the time may come for you to have your knee replaced.  This surgery involves removing your knee and replacing it with prosthetic components.  The bottom of your femur, your knee cap, and the top of your tibia will all be cut out.

Some reasons for having your knee replaced are listed below:

  • Severe knee pain while walking or standing
  • Knee pain while resting either or day or night
  • Chronic knee swelling
  • Knee deformity
  • Knee stiffness
  • Failure to obtain pain relief from other treatment options
  • Inability to take medications


Knee Exercise

Knee Exercise

Pre-operative exercise programs help patients with osteoarthritis of the knee after they have their knees replaced.  People who undergo “pre-habilitation” experience better leg function and faster recovery times.

So even if you decide to have total knee replacement surgery you still have to exercise!

71 patients were divided into two groups at the University of Louisville.  One group underwent an exercise program before surgery.  The exercises was developed to improve knee and leg strength, through light walking and step exercises.  Standard preoperative care was provided to the other group of patients.

The group that exercised before they had their knees replaced experienced less pain during functional tests and increased extension strength.  The findings published in the Journal of Strength and Conditioning suggests exercise before surgery results in quicker recovery.



This is a continuation of our series on the Osteoarthritis Research Society International (OARSI) recommendations for the management of hip and knee osteoarthritis published in the Journal of Osteoarthritis and Cartilage.

Unicompartmental Knee Surgery

Unicompartmental Knee Surgery

Recommendation XXII

Unicompartmental knee replacement is effective for patients with unicompartmental OA.

33% of the patients with knee osteoarthritis only have the disease in one compartment of their knee.  Nine studies and one randomized controlled trial were examined for this recommendation.  Knee pain and function were similar following unicompartmental knee replacement when compared to total knee replacement.

The research team gave this osteoarthritis treatment option a Strength of Recommendation score of 76%.
