Understanding Arthritis and Knee Pain
The knee joint features a layer of smooth cartilage positioned between the end of the thigh bone and the top of the calf bone. This cartilage acts as a cushion, enabling seamless knee movement. Arthritis refers to the gradual wearing away of this cartilage, eventually leading to its depletion and exposing the underlying bone. When bone rubs against bone, it results in discomfort, swelling, and stiffness. Knee pain is typically concentrated in the knee but can radiate to the thigh, calf, or the back of the knee. It often worsens after periods of immobility. In most cases, the inner part of the knee wears out first, followed by the outer side and the kneecap.
In a primary total knee replacement, the surfaces of the femur, tibia, and patella are replaced with implants. (The patellar component is not shown here.)
Exploring Total Knee Replacement
A total knee replacement is a surgical procedure that involves the removal of arthritic bone and damaged cartilage from the knee joint. The knee is then replaced with a metal and plastic prosthetic that mimics natural cartilage, restoring the joint’s smooth functionality and eliminating pain. The natural tendons and muscles are retained, allowing the joint to operate smoothly.
What to Expect After Total Knee Replacement
Approximately 95% of our patients report good to excellent results following the initial healing period. They experience minimal to no pain and can engage in a wide range of activities with few limitations. Most patients can participate in moderate exercise, walk long distances, drive, or even engage in active sports.

Timing for Surgery
The decision to undergo surgery is based on the patient’s history and examination. Surgery is typically recommended when non-operative methods no longer provide pain relief.
Age and Eligibility
Age is not a limiting factor if you are in reasonable health and have the desire to maintain a productive and active life.
Scar and Mobility Aids
The scar from the surgery is usually about four to five inches long. For the initial three weeks, it is advisable to use a walker or crutches.
To break up scar tissue, your doctor may perform manipulation under anesthesia.
Physical Therapy and Rehabilitation
We will arrange for a physical therapist to provide therapy at your home. Following this, you may need to visit an outpatient facility two or three times a week to support your rehabilitation.
Return to Normal Activities
You can typically resume driving within three weeks and should take at least four weeks off from work.
Implants
We offer a variety of imported implants to suit your individual needs.
