Knee Replacement

When your knee has been damaged by injury or by degenerative conditions, you may feel extreme discomfort when doing even basic activities, and you may not feel relief from pain even when lying down or sitting. After you try pain medication, using an elastic bandage or knee brace to support your knee or incorporating a cane or walker into your daily activities, you may decide to undergo Knee Replacement Surgery.

In the Coachella Valley, when you want Knee Replacement or other joint surgeries, the person to do the surgery is Dr. Raj Sinha, a leader in Orthopedic Surgery, and a pioneer in developing many of the techniques used in modern Knee Replacement.

Who Are Good Candidates For Knee Replacement Surgery?

Knee Replacement Surgery, according to the American Academy of Orthopaedic Surgery, is the choice of more than 600,000 people each year; it is predicted that the number of these surgeries performed will increase by 3% annually until 2030. The reason for the current and ongoing popularity of this surgery is that the procedure is safe and effective for most people, with 90% of patients claiming that they feel much less pain and have improved mobility.

Good candidates for knee surgery:

  • Suffer from severe knee pain or stiffness that makes it necessary to walk with a cane or walker
  • Have severe amounts amount of knee pain even at rest
  • Experience chronic knee inflammation, even after resting or taking medication
  • Have knee deformity such as bowing of the knee
  • Show no improvement from other treatments

While there are no age or weight restrictions for this surgery, an orthopedic surgeon evaluates each patient individually. The majority of knee surgeries are done on people between ages 50 and 80, but these operations have successfully transformed the lives of young patients with juvenile arthritis, or who have sustained injuries. While weight is not an impediment to having the surgery, a physician will carefully examine all conditions that might pose surgical risks.

The Anatomy Of Knee Surgery

As the largest joint in body, the knee is comprised of a group of bones, cartilage, and ligaments

  • Three bones come together to make the knee: lower end of the thighbone (femur), the end of the shinbone (tibia), and the kneecap (patella).
  • C-shaped pads of cartilage, known as the menisci, serve as shock absorbers between the femur and the tibia to cushion the joint.
  • Ligaments provide stability by holding the femur and tibia together.
  • The surfaces of the knee are covered with the synovial membrane, a thin lining that releases fluid that lubricates the cartilage.

All the parts of the knee work together until disrupted by injury or disease. Arthritis of all types impacts the cartilage and makes the knee painful and less functional.

Understanding Knee Replacement Surgery

When the surgeon recommends Total Knee Replacement, the operation includes four basic steps:

  • Preparing the bone by removing damaged cartilage and small amounts of bone.
  • Positioning the implants that replace the cartilage and bone and attaching them with cement or by press fitting.
  • Resurfacing the undersurface of the kneecap.
  • Inserting a plastic spacer between the components to make the knee glide smoothly.

Dr. Sinha and others have developed minimally invasive methods for Knee Replacement that work with many patients. This procedure, most often used on more agile patients, involves making a smaller incision and using specialized instruments to place the implant after preparing the femur and tibia.

Before the surgery, your physician will evaluate your medical history, physical examination, x-rays, and other tests to determine the best approach to knee surgery.
