Femoral retroversion surgery

Femoral retroversion may lead to pain, difficulty walking, or reduced athletic performance. Surgery is typically considered when symptoms are severe, significant "out-toeing" or symptoms do not improve with conservative measures such as physiotherapy, orthotics, or activity modification.

What is femoral retroversion surgery?

Femoral retroversion surgery is an orthopaedic procedure designed to correct abnormal rotation of the thigh bone (femur). In femoral retroversion, the femur is rotated backwards more than normal, which can cause the hips, knees, or feet to point outward.With reduced internal rotation, hip pain is a result of dynamic impingement.

What does the procedure involve?

The operation, called a femoral derotation osteotomy, involves carefully cutting the femur, rotating it into the correct alignment, and stabilising it with a plate, screws, or rod while it heals. This restores a more normal position of the hip and leg, improving function and reducing discomfort. Foot direction is corrected and the hip has more internal rotation.

The procedure is usually performed under general anaesthetic and may take two to three hours depending on the complexity. Modern imaging techniques and computer-assisted tools help surgeons achieve precise correction, minimising the risk of over- or under-rotation.

When is surgery recommended?

Surgery is usually advised when:

Pain, limping, or fatigue significantly affects daily activities.
Abnormal gait or outward-pointing legs cause functional or cosmetic concerns.
Other treatments have failed, such as physiotherapy or bracing.
Hip or knee problems are developing due to malalignment.

In children, surgeons carefully weigh the decision because the bones are still growing. In adults, correction may prevent joint damage or arthritis later in life.

What is recovery like?

Recovery involves a combination of hospital care, rest, and structured rehabilitation:

Hospital stay is usually a few days to monitor healing and manage pain.
Weight-bearing on the operated leg is gradually reintroduced, often with crutches for 6 to 8 weeks.
Physiotherapy plays a major role in restoring strength, mobility, and walking patterns.
Full recovery may take several months, but improvements in gait and comfort are often noticeable within weeks.

The bone typically heals solidly, but regular follow-up and X-rays are essential to ensure proper alignment during the recovery period.

What are the risks?

Like any major surgery, femoral retroversion correction carries some risks, though these are uncommon when performed by experienced surgeons. Potential complications include:

Infection or bleeding
Nerve or blood vessel injury
Incomplete or delayed bone healing
Over- or under-correction of the rotation
Persistent pain or stiffness

Careful planning, modern surgical techniques, and structured rehabilitation help reduce these risks.

How successful is femoral retroversion surgery?

Femoral derotation osteotomy has a high success rate in improving hip and leg function, reducing pain, and correcting abnormal gait. Many patients return to normal daily activities and even sports after full rehabilitation. Long-term benefits include improved joint alignment, which can help prevent hip or knee arthritis in the future.
