Rotationplasty Surgery: Procedure, Recovery and Results

Rotationplasty surgery is a limb-preserving reconstruction most often used to treat certain bone tumors around the knee in children, teenagers, and selected adults. The lower leg is rotated 180 degrees and reattached, allowing the ankle to work like a knee joint inside a specially designed prosthetic leg.

Overview: How rotationplasty surgery works

Rotationplasty surgery is a complex reconstructive operation that may be offered when a tumor affects the bone around the knee. It is used most often for osteosarcoma or Ewing sarcoma in the lower part of the thigh bone (femur) or upper part of the shinbone (tibia), although it can sometimes be considered for other severe limb conditions. The procedure removes the part of the limb containing the disease while preserving the lower leg, ankle, foot, blood supply, and key nerves when this can be done safely.

During the reconstruction, the lower leg is turned 180 degrees before it is reattached. The foot points backward, and the ankle is positioned at the level where a knee would normally be. When the person wears a tailored prosthesis, ankle movement can function similarly to knee movement. This can provide a stable, durable limb for walking and many daily activities.

Rotationplasty is not the right option for every person. The decision involves careful cancer staging, imaging, surgical planning, and discussion of personal goals. It is one form of orthopedic oncology treatment that may be considered alongside limb-sparing tumor removal, reconstruction, or amputation.

Who may be a candidate for rotationplasty?

Rotationplasty is generally considered when complete tumor removal would require taking out the knee joint and a substantial section of nearby bone. It may be particularly useful for growing children and adolescents, because conventional joint replacement devices may need revision as the child grows. In selected adults, it can also offer a functional alternative when other reconstructions are not expected to provide reliable long-term use.

For the procedure to be feasible, surgeons must be able to remove the tumor with an adequate margin while preserving or safely reconstructing important blood vessels and nerves. The ankle and lower-leg muscles also need to have enough function to support prosthetic control. Imaging studies help the team assess the tumor’s relationship to bone, muscles, nerves, and vessels.

Suitability is individual. Tumor type, location, size, response to chemotherapy when indicated, spread of disease, prior operations, overall health, expected rehabilitation needs, and the person’s preferences all matter. A multidisciplinary team commonly includes orthopedic oncologic surgeons, medical oncologists, radiologists, pathologists, plastic or vascular surgeons when needed, physiotherapists, prosthetists, and psychosocial support professionals.

• Children or adults with a tumor involving the knee region may be assessed.
• The tumor must be removable with cancer-safe surgical margins.
• Blood supply and nerve function in the lower leg must be suitable for reconstruction.
• The person and family should understand the visible change in limb appearance and the rehabilitation commitment involved.

Step by step: What happens during the procedure?

Before surgery, the team performs detailed imaging, which may include X-rays, MRI, CT, and scans to check for spread of cancer. They also plan the bone cuts, blood vessel management, muscle balancing, and eventual prosthetic alignment. If chemotherapy is part of the treatment plan, surgery may take place after initial chemotherapy or within a schedule tailored to the specific cancer.

Under general anesthesia, the surgeon removes the tumor and the involved section of bone, including the knee joint when necessary. The lower leg, ankle, and foot are preserved. Major blood vessels and nerves are carefully protected where possible; in some cases, vessels are divided and microsurgically reconnected. The lower leg is then rotated so that the ankle points in the opposite direction.

The remaining bones are fixed together with surgical hardware, such as plates, screws, or rods, to allow healing. Muscles and soft tissues are repositioned to support movement and coverage, and the surgical wound is closed. The operation is highly individualized and can take several hours, particularly if vascular or soft-tissue reconstruction is needed.

After surgery, the person is closely monitored in hospital. The care team checks circulation, sensation, pain control, wound healing, and the position of the limb. Pathology results are reviewed to confirm information about the tumor and surgical margins, which helps guide any further cancer treatment.

Why do they rotate the leg in rotationplasty?

The leg is rotated so the ankle can take on the mechanical role of a knee joint. After the foot is turned backward, pointing the ankle downward can act like bending a knee, while lifting the ankle upward can act like straightening it. A custom prosthesis is built around the rotated limb to use these movements for standing, walking, stairs, and other activities.

This design preserves a person’s own ankle muscles and joint sensation, which can give active control of the prosthesis. Compared with a prosthesis used after an above-knee amputation, the ankle-based “new knee” may use less energy for walking and can provide strong functional potential. Outcomes vary, however, and depend on healing, strength, prosthetic fit, rehabilitation, and individual circumstances.

The appearance of the backward-facing foot can feel unfamiliar and may be emotionally challenging at first. Preoperative conversations, meeting rehabilitation and prosthetic specialists, and where available speaking with people who have undergone similar surgery can help families make an informed decision.

Rotationplasty recovery timeline and rehabilitation

Hospital recovery varies according to the complexity of surgery, wound healing, and whether other cancer treatment is required. In the first days and weeks, care focuses on pain relief, protecting the surgical site, monitoring blood flow, preventing complications, and beginning safe movement as advised by the surgical team. A cast, brace, or other support may be used while the bone junction heals.

Physiotherapy usually begins in stages. Early therapy can include breathing exercises, gentle mobility, transfer practice, strengthening of the upper body and unaffected leg, and learning to move safely with temporary supports. Weight bearing is introduced only when the surgeon confirms that healing is progressing appropriately.

Once swelling has reduced and the limb is sufficiently healed, a prosthetist measures and designs a custom prosthesis. Fitting and adjustment are an ongoing process, especially for children who are growing. Rehabilitation then focuses on balance, ankle control, gait training, endurance, stairs, school or work activities, and goals such as sports or recreation.

Recovery is better viewed as a progression than a fixed timetable. Many people need months of rehabilitation before achieving comfortable, confident prosthetic use. Ongoing reviews with the surgical, oncology, rehabilitation, and prosthetic teams remain important, particularly during cancer surveillance and periods of growth.

What are the risks of rotationplasty?

Rotationplasty is major surgery, so it carries risks that should be discussed carefully before treatment. Early complications can include bleeding, blood clots, infection, wound healing problems, pain, and reactions related to anesthesia. Because the operation involves important blood vessels, reduced blood flow to the lower leg is a rare but serious concern that requires prompt assessment.

Nerve injury or nerve-related pain can occur, and some people experience altered sensation in the foot or lower leg. Bones may heal slowly or fail to unite fully, and surgical hardware may occasionally need adjustment or replacement. Further surgery may be needed if there is infection, a bone-healing problem, a vascular issue, tumor recurrence, or difficulty achieving a stable prosthetic fit.

There are also practical and emotional considerations. The altered appearance of the limb, adapting to a prosthesis, body image concerns, and changes in social confidence can be significant for some people. Counseling, peer support, child-life services for younger patients, and rehabilitation psychology can be valuable parts of care.

For people undergoing surgery for cancer, risks related to the cancer itself and additional treatment, such as chemotherapy, must also be considered. The treating team explains how these factors apply to the individual situation and provides clear instructions for monitoring recovery.

What are the long-term outcomes of rotationplasty?

Long-term outcomes of rotationplasty can be very good in appropriately selected patients. Many people achieve independent walking, use stairs, attend school or work, drive when appropriate, and participate in recreational or athletic activities with a well-fitted prosthesis. The preserved ankle can provide active control that supports efficient, stable movement.

For people treated for bone cancer, the most important long-term outcome is cancer control. This depends on the cancer type, stage, response to systemic treatment, and whether the tumor was removed completely, rather than on reconstruction alone. Regular follow-up examinations and imaging are therefore essential after surgery.

Rotationplasty may reduce some of the revision needs associated with tumor endoprostheses, particularly in growing children. Nevertheless, prosthetic components require maintenance and periodic replacement, and the limb may need adjustments as a child grows or activity needs change. Some people also need treatment for skin irritation, alignment issues, pain, or bone and muscle changes over time.

Long-term wellbeing includes more than walking ability. Most people benefit from continued access to rehabilitation, prosthetic expertise, and emotional support. The best reconstruction is the one that combines safe cancer surgery with realistic functional goals and the person’s own values.

When to seek medical care

Anyone recovering from rotationplasty should contact their surgical team promptly for increasing redness, warmth, swelling, wound drainage, fever, worsening pain, new numbness, a cold or pale foot, sudden changes in limb color, or trouble moving the ankle. These symptoms do not always mean there is a serious complication, but they need timely medical assessment.

Urgent medical care is also needed for chest pain, shortness of breath, fainting, or sudden swelling and pain in the unaffected leg, as these can be warning signs of a blood clot or other urgent condition. People receiving chemotherapy should follow their oncology team’s instructions about fever and signs of infection.

Before and after surgery, it is important to attend planned oncology and orthopedic follow-up appointments. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat bone tumors and coordinate surgical, cancer, rehabilitation, and prosthetic care for international patients.

Frequently asked questions

Is rotationplasty an amputation?

Rotationplasty involves removal of the diseased part of the limb, often including the knee joint, but it preserves and repositions the lower leg, ankle, and foot. It is therefore a specialized reconstructive procedure that combines tumor removal with functional use of a prosthesis. The terminology may vary between clinical teams, but the goal is to retain active ankle function for prosthetic control.

Can a person walk normally after rotationplasty surgery?

Many people can walk independently with a custom prosthesis after rehabilitation. Their gait may look different from typical walking, and adjustment takes time, but the rotated ankle can provide active control similar to a knee. Function depends on healing, strength, prosthetic fit, rehabilitation, and individual health factors.

How long does recovery from rotationplasty take?

Initial surgical healing takes weeks, while rehabilitation and prosthetic training usually continue for several months. The exact pace differs based on bone healing, wound recovery, cancer treatment schedules, age, and rehabilitation goals. Children may need repeated prosthetic adjustments as they grow.

Can rotationplasty be done after chemotherapy?

Yes. For several bone cancers, chemotherapy is commonly given before and/or after surgery as part of the overall treatment plan. The oncology and surgical teams coordinate timing to balance cancer treatment, blood counts, wound healing, and recovery needs.

Does rotationplasty cause pain?

Pain is expected after major surgery and is managed with an individualized plan in hospital and during recovery. Some people may have longer-lasting discomfort, nerve-related symptoms, or phantom sensations, although the foot is preserved. Ongoing pain should be discussed with the care team because rehabilitation, prosthetic adjustment, medication, and pain specialists may help.

Can people play sports after rotationplasty?

Some people return to sports, exercise, and active recreation after healing and training with a prosthesis. The activities that are suitable depend on bone healing, cancer recovery, fitness, prosthetic design, and medical advice. A physiotherapist and prosthetist can help set safe, realistic goals.
