  • Research summary

    Knee arthritis is a crippling condition, which will affect a large proportion of the population. A knee replacement is the mainstay of treatment for this in the elderly population; however in the young active patient a knee replacement is undesirable due to its limited lifespan. In these cases osteotomies are used to realign deformity and reduce the pressure on the joint.

    Knee osteotomy is commonly used to realign arthritic damage on one side of the knee. The goal is to shift the patient's body weight off the damaged area to the other side of the knee, where the cartilage is still healthy. Surgeons remove a wedge of the tibia from underneath the healthy side of the knee, which allows the tibia and femur to bend away from the damaged cartilage.

    Osteotomy is also used as an alternative treatment to total knee replacement in younger and active patients. Because prosthetic knees may wear out over time, an osteotomy procedure can enable younger, active osteoarthritis patients to continue using the healthy portion of their knee. The procedure can delay the need for a total knee replacement for up to ten years

    Osteotomies are very successful; however recent audits have shown that planned corrections are achieved in less than 40% of cases.

    The purpose of this project would be to use 3D modeling and rapidprotopying technology to increase the accuracy of this procedure, thereby improving the outcome achieved. This will improve the patients function and pain, allowing them to continue worthwhile employment.
