MAKO Robot-Assisted TKA Shows Superior Early Outcomes Over Conventional Methods: Study

Both surgical groups successfully completed the procedures without major intraoperative complications. Key findings include:

Radiographic Parameters:

• Postoperative LDFA and HKA were significantly lower in the MA-TKA group compared to the CM-TKA group (P < 0.05).

• At the one-month follow-up, 86.4% of patients in the MA-TKA group had an HKA less than 3°, compared to 76.9% in the CM-TKA group.

Clinical Outcomes:

• VAS scores at 24 hours, 48 hours, and 72 hours postoperatively were lower in the MA-TKA group both at rest and during activity.

• AKSS Function Scores and FJS-12 scores at one month and three months postoperatively were significantly higher in the MA-TKA group compared to the CM-TKA group (P < 0.05).

Postoperative Complications:

• No complications were reported in the MA-TKA group.

• One patient in the CM-TKA group experienced postoperative knee stiffness, which resolved after physical therapy.

The findings suggest that MAKO robot-assisted TKA offers superior early postoperative outcomes compared to conventional manual TKA. The improved radiographic parameters and higher functional scores indicate better alignment and overall clinical efficacy with the robot-assisted technique. The absence of complications in the MA-TKA group further supports the safety of this advanced surgical method.

This study concludes that MAKO robot-assisted TKA demonstrates better short-term clinical efficacy, improved alignment planning, and maintains good safety compared to conventional manual TKA. These results may encourage the adoption of robotic assistance in TKA procedures, potentially leading to better patient outcomes.
