Summary:
For many years, the use of computer-assisted navigation has been touted as improving the positioning, sizing and alignment of replacement knee joints, resulting in greater durability of joints and overall improvement in patient movement. But new research suggests there is no difference in knee function, pain, mobility and activity level between computer-assisted navigation and traditional surgery.

- For many years, the use of computer-assisted navigation has been touted as improving the positioning, sizing and alignment of replacement knee joints, resulting in greater durability of joints and overall improvement in patient movement. However, new research published in the Journal of Bone and Joint Surgery (JBJS) found no difference in knee function, alignment or durability/survivorship between joints positioned and completed with the help of computer navigation, and those replaced with conventional total knee arthroplasty (TKA) procedures.

Researchers in Korea compared the results of 520 patients with osteoarthritis who underwent computer-navigated TKA for one knee and conventional TKA for the other knee. Patients included 452 women (904 knees) and 68 men (136 knees). Patients were assessed before surgery, and then at three months and one year following surgery, and annually thereafter, for 10 to 12 years (mean assessment duration: 10.8 years). Patients were assessed clinically using the Knee Society rating system and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and. radiographically using X-rays or CT scans.

No statistically significant differences were noted between the computer-navigated and traditional procedure scores pertaining to knee function, pain, knee motion and activity, according to the study. In addition, the Knee Society and WOMAC scores were comparable for both procedures.

"Our mid-term follow-up data demonstrated no difference in clinical function or alignment and survivorship of the components between the knees that underwent computer-navigated total knee arthroplasty and those that underwent conventional total knee arthroplasty," said Young-Hoo Kim, MD, The Joint Replacement Center, Ewha Womans University School of Medicine in Seoul, Korea.
