Osteotomy or knee replacement: which makes sense in my 40s or 50s?

The core trade-off

An osteotomy is a joint-preserving operation. It changes how load passes through your own knee, so there are no implants inside the joint to wear out and fewer restrictions on impact activity once the bone has healed. The price is a longer recovery, since bone must heal, and pain relief that is usually good but less complete than a replacement when wear is advanced.

A partial or total knee replacement removes the worn surfaces. Pain relief is often more predictable for bone-on-bone arthritis, but high-impact running and contact sport are generally discouraged, and a younger patient may need revision surgery during their lifetime.

Side-by-side comparison

• Keeps your own cartilage and ligaments: osteotomy yes; partial mostly; total no
• Typical patient: osteotomy younger and active with moderate wear; partial one-compartment advanced wear; total widespread wear
• Crutches: osteotomy usually several weeks; replacements usually shorter
• Return to high-impact activity: more realistic after osteotomy
• Future options: an osteotomy can later be converted to a replacement if needed

What tips the balance

The deciding factors are how severe the wear is, how bowed the leg is, the state of the outer compartment and kneecap, ligament stability, your range of movement, smoking and weight, and above all what you want to do. A 42-year-old padel player with moderate inner-side wear and a clearly bowed leg is a classic osteotomy patient. A 58-year-old with bone-on-bone wear on one side and a straighter leg may do better with a partial replacement.

Getting a tailored opinion

There is rarely one right answer for every knee. At Aman Hospital in Doha, Dr. Gelber reviews long-leg alignment X-rays, MRI findings and your goals, and explains the expected recovery and long-term outlook of each option so you can choose with clear information.
