Osteotomy Surgery
in Perth, WA

Osteotomy surgery is a joint-preserving option for patients with early arthritis or joint damage isolated to one side of the knee.

At Dr. Samuel Duff’s orthopaedic clinic, we use carefully planned osteotomy techniques to realign the leg and relieve pressure on the worn part of the joint — without replacing it.

ABOUT

What Is Osteotomy and Who Is It For?

Osteotomy reshapes knee bones to shift weight away from damaged cartilage, relieving pain and delaying joint replacement.

Ideal for active patients under 55 with one-sided arthritis.

What Is an Osteotomy?

An osteotomy is a surgical procedure that involves reshaping or repositioning a bone to alter how forces travel through the joint. Around the knee, it’s commonly used to shift the body’s weight away from the damaged cartilage and onto healthier areas — delaying the need for joint replacement.

There are several types of osteotomies depending on alignment:

  • High Tibial Osteotomy (HTO): For bow-legged patients (varus) with inner knee wear
  • Distal Femoral Osteotomy (DFO): For knock-kneed patients (valgus) with outer knee wear
  • Torsional and rotational osteotomies: For abnormal leg or patella tracking


These procedures may also be combined with cartilage repair or meniscus surgery if needed.

Osteotomy is most appropriate for:

  • Patients under 55 with one-sided knee arthritis
  • Active individuals not ready for the limitations of joint replacement
  • People who have exhausted non-operative measures such as physiotherapy, injections, and bracing

 

If joint degeneration becomes more widespread in future, an osteotomy does not prevent you from proceeding to a Total Knee Replacement later.

The main goal of osteotomy is to relieve pain and improve function by shifting weight-bearing to the healthier side of the knee.

Key benefits include:

  • Retaining your natural knee joint
  • Delaying or avoiding total joint replacement
  • No long-term activity restrictions once healed
  • Potential to return to physically demanding work or sports


This makes osteotomy an attractive option for young, active patients whose lifestyles are not compatible with prosthetic joint limitations.

As with all surgeries, osteotomy carries potential risks:

  • Infection
  • Blood clots
  • Knee stiffness
  • Delayed healing of the osteotomy site
  • Irritation from metal implants
  • Damage to nearby blood vessels or nerves (rare)

 

Dr. Duff will discuss these risks in detail and guide you through a recovery plan.

How Is Surgery Performed?

Dr. Duff uses digital planning and specialised imaging to calculate the exact angle needed for correction.

Movement of the knee typically begins within the first week, although partial weight-bearing is required initially to allow the osteotomy to heal properly.

During the procedure:

Timeline Scroll Progress

1. The targeted bone (tibia or femur) is cut in a controlled fashion

2. The angle of the leg is opened or closed to change alignment

3. The new position is secured with a plate and screws

4. Over 6–10 weeks, the bone heals naturally into its new position

What to expect​

Most patients:

  • Stay in hospital for 1–2 nights
  • Use crutches for 4–6 weeks
  • Begin physiotherapy early to regain motion and strength
  • Return to full activities gradually over 3–6 months


The bone typically heals by 10–12 weeks, after which weight-bearing and more intensive exercise can resume.

Book an Osteotomy Consultation

If you have early knee arthritis or pain localised to one side of the joint, osteotomy may offer long-term relief while preserving your natural knee.
