Knee surgery

From arthroscopy under local anaesthesia for a meniscus tear to robotic total knee replacement for osteoarthritis: modern treatment for every knee condition.

  • Robotic joint replacement
  • Arthroscopy as a day case
  • Sports injuries

Your knee in experienced hands

The knee is the largest joint in the body and one of the most heavily loaded, both in sport and with age. Marios Salmas treats the full range of knee conditions: meniscus and ligament tears, injuries and fractures, kneecap (patella) disorders and osteoarthritis.

His team has performed more than 2,000 knee and hip replacements since 1998 and today performs active robotic joint replacement with the TSolution One® system.

Patient testimonials

What our patients say

G
5.0425 reviews

“I feel the need to thank, from the bottom of my heart and publicly, orthopaedic surgeon Professor Marios Salmas for the perfect operation on my knee – a robotic total knee replacement that freed me from the unbearable pain that tormented me. I am in my eighth decade of life, and my recovery was immediate, painless and without needing a walking stick or a walking frame. On the very day of the operation I walked on my own without any help, and on the third day I climbed stairs. Now, one week after the operation, I move as I did at 40, without the terrible pain that tormented every movement, and without needing physiotherapy.”

EPEleni PortouliKnee replacement

“My mother had surgery on Monday 27/4/2026 at Eugenideio Hospital with Prof. Salmas (total joint replacement). An exceptional person, an exceptional doctor. My mother, who is 79, walked on the same day as the operation. Zero pain after the surgery. Today she was discharged and her leg is working perfectly.”

ETEleftheria TerpeniKnee replacement

“A big thank you to this wonderful person and excellent doctor! He operated on my 91-year-old father. Four hours after the operation he was walking in the corridors, and the next day he climbed 12 steps on his own. An experienced doctor who deserves many congratulations.”
