Robotic-assisted knee surgery's growth, market outlook, biggest players & more


Surgeons are increasingly using robotic technology for knee surgery, and the rate of robotic-assisted knee reconstructions is expected to keep growing in the next decade, according to a July 1 report from GlobalData.


"In comparison with a conventional procedure, robotic total knee surgery improves surgeons’ consistency and accuracy to control implant positioning, ligament balance, and limb alignment, leading to decreased postoperative pain, a shorter stay in the hospital, and better knee flexion on discharge," said Tina Deng, principal medical device analyst at GlobalData. "Despite the drawbacks such as a learning curve, the financial costs, and lack of long-term clinical data, most joint reconstruction surgeons support the usage of orthopedic robots to improve precision and short-term patient outcomes in knee reconstruction surgeries."

Five takeaways:

1. Robotic-assisted knee surgeries are expected to hit 700,000 by 2030.

2. From 2021 to 2030, robotic-assisted knee surgeries are expected to have a compound annual growth rate of 8 percent.

3. There are about 3 million knee surgeries performed worldwide every year, and in 2020 about 11 percent included robotic assistance.

4. Four robotic systems control more than 95 percent of the knee surgery market:

  • Mako from Stryker
  • Rosa from Zimmer Biomet
  • Cori from Smith+Nephew
  • Velys from Johnson & Johnson

5. Ms. Deng expects competition to intensify in the capital equipment and consumables market for robotic-assisted knee surgery systems.
