Advances in Knee Replacements

This new design allows surgeons to preserve the important central ligaments of the knee called the anterior and posterior cruciate ligaments. This design should allow a knee replacement to move, respond, and feel more like a normal knee.

The Anterior Hip

Patients are being told by both surgeons and orthopedic implant companies that Anterior Hip Replacement approach offers something unique and different compared to other approaches. This is a flatly untrue, unscientifically supported myth...

Custom-Fit Knee Replacement in Portland, Oregon

Each patient has a unique musculoskeletal system, resulting in slight differences in joint size and shape. These slight differences can contribute to less accurate joint placement and improper alignment of traditional knee replacements. Custom-fit knee replacement is a surgical procedure that aims to improve the fit of knee implants, potentially resulting in improved alignment and a more natural feeling knee. Schedule an appointment to speak with Dr. Ballard at his two Portland-area offices to learn more.

The knee is the largest joint in the human body, comprised of three bones: the femur (thighbone), the tibia (shinbone), and the patella (kneecap). The end of the femur meets the top of the tibia to form the main hinge joint, which is protected anteriorly (in the front) by the patella.

The Development of Knee Arthritis

During normal movement, the knee experiences stress from carrying the body's weight. Two soft pieces of cartilage, known as the menisci, lie between the femur and the tibia, acting as shock absorbers during routine activity. The cartilage also provides a smooth surface for the bones to glide on with very little friction.

Osteoarthritis refers to a wear-and-tear condition that makes extending the knee painful and uncomfortable. Due to friction, excessive stress, and natural degeneration, the meniscus becomes brittle and less capable of protecting the knee. Over time, the meniscus deteriorates and makes movement painful, causing bones to rub against one another.

Knee Arthritis Treatment

To treat osteoarthritis, patients may opt to replace the arthritic knee with a prosthetic implant made of metal, strong plastics, and sometimes ceramic. This procedure, total knee replacement surgery, is an effective method of restoring joint function and alleviating knee pain.

Following a post-operative recovery period, patients should experience significantly less joint pain, and may be able to return to previous levels of activity. Knee replacement implants are durable, and typically have a lifespan between ten to twenty years.

Custom-Fit Knee Replacement Surgery

Innovations in technology and implant design have given patients more options for knee replacement. These innovative new procedures, such as custom-fit knee replacement, can potentially result in improved joint placement and increased alignment. These improvements can potentially mean a more naturally feeling joint compared to a traditional "one-size-fits-all" knee replacement. Additionally, the improved fit can lead to greater wear characteristics, potentially increasing the implant's lifespan.

Custom-fit knee replacement benefits from computer-aided measurements of the patient's joint, which allows the surgeon to plan the surgery before entering the operating room. Using MRI imaging and special computer software, the surgeon will build a 3D model of the arthritic knee. Based on the 3D model, the surgeon can develop a customized knee implant that matches the patient's anatomy and improves the joint's alignment and fit.
