1. What is joint replacement surgery?

Joint replacement surgery is a procedure most often recommended for patients suffering from chronic joint pain, or those unable to complete necessary daily activities due to joint immobility. The most common causes of chronic joint pain, for which joint replacement is frequently recommended, is osteoarthritis and rheumatoid arthritis. During the procedure, Dr. Kastrup removes and replaces the diseased or damaged joint with an artificial joint, known as prosthesis, designed to replicate the function of the natural joint. The most commonly replaced joints are the knee, hip, and shoulder.

3. Who will benefit most from hip replacement surgery?

Total hip replacement surgery is recommended for patients suffering from advanced arthritis of the hip, such as osteoarthritis and rheumatoid arthritis. As arthritis develops, it can cause permanent bone damage, increasing hip pain, swelling around the affected joints, decreasing range of motion, and difficulty completing required daily activities. Total hip replacement surgery may be recommended for patients suffering from advanced arthritis of the hip, which can cause the loss of the joint mobility, while rendering patients unable to manage pain symptoms using conservative treatments. Dr. Kastrup will complete an in-depth evaluation of the location and severity of joint damage in order to determine if total hip replacement surgery is the best treatment for relieving pain symptoms and returning joint function.

4. Does Dr. Kastrup use minimally invasive techniques during joint replacement?

Dr. Kastrup is dedicated to always using the most advanced techniques during joint replacement surgery, including minimally invasive surgery. Minimally invasive surgery is an advanced surgical technique that offers patients the same benefits of traditional joint replacement with decreased disruption to the surrounding muscle and tissue. In addition, when using minimally invasive techniques, Dr. Kastrup will use an incision approximately 6 inches long. This is about half the length of a normal incision, decreasing the amount of post-op scaring. The smaller incision and decreased disruption to the surrounding area can also minimize post-operative recovery time. Minimally invasive techniques are most often used during hip replacement, total knee replacement, and partial knee replacement.

5. What are the benefits of custom-fit knee replacement?

Dr. Kastrup specializes in custom-fit technology for total knee replacement surgery. Custom-fit knee implants are based on the patient’s unique anatomy, designed off a 3-D model of the patient’s knee, as created from MRI images. Using customized guides, the individualized implant is attached to the ends of the bones in order to most closely match the anatomy of the knee. Due to the more precise attachment of the implant, custom-fit knee replacement patients often experience a more natural fit and post-operative movement, improved range of motion, decreased recovery time, and a longer implant life. The increased lifespan of the implant is due to the more natural fit, which results in decreased pressure during movement.
