TruMatch® Total Knee Replacement

What is TruMatch® Total Knee Replacement?

Total knee replacement is a surgical procedure to replace the weight-bearing surfaces of the knee joint.

During total knee replacement, the surgeon removes damaged cartilage surfaces at the ends of the femur (thighbone) and tibia (shinbone) and replaces them with an implant called a prosthesis. A plastic spacer is attached to the prosthesis to create a cushioning effect much like the original cartilage in your knee.

TruMatch® total knee placement is an advanced technique that features made-to-measure implants and patient-specific instrumentation for precise alignment and faster, safer, more efficient surgery.

A simple CT scan is used to develop a 3-D computerized model of the entire leg structure and create a customized surgical guide, based on each patient’s unique anatomy. With fewer surgical steps and less equipment in the OR, surgery is quicker, the risk of infection is significantly lower, and patients spend less time under anesthesia, which reduces the chance of complications such as blood clots.

Using the CT scan ahead of time to align and size the joint more perfectly makes it much more of custom fit than previous models that simply came in different sizes. The customized surgical guide improves the placement and positioning of the implant, which is critical for overall performance and long-term success. This level of precision improves alignment and stability, which results in less wear and tear over time and helps the implant last longer.


The knee is the largest joint in the body and one of the most complex. It is made up of the femur, tibia and patella (kneecap). Damage can result from injury, deformity or arthritis, when the articular cartilage that cushions the ends of the bones gradually erodes. Without this cushioning effect, the bones of the knee joint rub together. The knee can't move easily and becomes stiff, swollen and painful.

When is surgery recommended?

If you have knee pain that limits your everyday activities and all non-surgical methods of treatment have failed – including weight loss, anti-inflammatory medications, cortisone injections, lubricating injections and physical therapy – then you should consider total knee replacement surgery.

Good candidates for TruMatch total knee replacement are men or women with knee deformities or previous fractures, as well as those with osteoarthritis. However, the way a knee replacement will perform depends on a number of factors, including a patient’s age, weight, activity level, and overall health. It is important that each patient is carefully screened by an orthopaedic surgeon to determine the most appropriate type of procedure.

What is the recovery time?

Because TruMatch total knee replacement requires fewer steps, surgery is more efficient, which usually results in a much faster recovery. Most patients are up and walking immediately following surgery and regain range of motion, strength and flexibility after several weeks of physical therapy. Hospital stays have been reduced to one or two days and the vast majority of patients can go directly home without having to use a rehabilitation center. As with all surgical procedures, specific recovery time varies by patient and demand.
