Similar short-term clinical outcomes, such as reduction of mechanical axis alignment and joint-line deviation outliers, were found among patients who underwent robot-assisted and conventional total knee arthroplasty, according to study results.
From May 2012 to December 2012, researchers inSingapore randomly assigned 31 patients to undergo robot-assisted total knee arthroplasty (TKA) and 29 patients to conventional TKA. Patients had weight-bearing radiographs taken at one-month follow-up. The researchers examined clinical outcome markers, such as postoperative Knee Society score, Knee Society function score, Oxford knee score, SF-36 score and range of motion, at six months. Additionally, operative times, length of hospital stay and any perioperative complications were recorded as well.
Results showed no overall difference at six-month follow-up in terms of clinical outcome measures. However, the robot-assisted group demonstrated higher SF-36 vitality scores, according to the data.
The analysts also found the conventional group had 19.4 percent coronal plan mechanical axis outliers and 10.3 percent cases with anterior femoral notching compared with the robot-assisted group. According to the study results, the robot-assisted group had 3.2 percent joint line shift outliers vs. 20.6 percent in the conventional group.
