Osteotomy

Knee pain does not always mean that the entire joint is damaged. In some patients, cartilage wear is concentrated mainly on one side of the knee and may be associated with an alignment problem in the leg. In carefully selected patients, osteotomy can be used to change the distribution of load across the knee and reduce excessive pressure on the damaged part of the joint.

Osteotomy is a joint-preserving orthopedic procedure. Rather than replacing the knee joint, the operation aims to improve the mechanical alignment of the leg by making a controlled correction in the bone. This approach may be particularly valuable for active patients with localized knee damage who are not yet appropriate candidates for total knee replacement.

What Is an Osteotomy?

An osteotomy is a surgical procedure in which a bone is carefully cut and repositioned to correct alignment. Around the knee, the correction is most commonly performed on the tibia or femur, depending on where the deformity originates.

The purpose of the procedure is to change the mechanical axis of the leg. By doing so, body weight can be redistributed away from an overloaded and damaged part of the knee toward a healthier area of the joint.

Osteotomy does not replace damaged cartilage with new cartilage, and it is not suitable for every patient with knee arthritis. Its role is to improve the mechanical environment of the knee in appropriately selected patients.

Why Does Knee Alignment Matter?

During standing, walking, running, and climbing stairs, significant forces pass through the knee. Ideally, these forces are distributed appropriately across the joint. When the leg has an alignment problem, one side of the knee may carry a greater proportion of the load.

Over time, this increased mechanical stress may contribute to pain and cartilage deterioration in the overloaded compartment. This can occur in patients with a bow-legged alignment, known as varus alignment, or a knock-kneed alignment, known as valgus alignment.

Correcting the alignment can shift the weight-bearing forces toward a healthier part of the knee. This is the fundamental principle behind osteotomy surgery around the knee.

Who May Be a Candidate for Knee Osteotomy?

The decision to perform an osteotomy is highly individualized. Age alone does not determine whether the procedure is appropriate. The location of cartilage damage, degree of arthritis, leg alignment, activity level, knee stability, range of motion, and patient expectations all need to be considered.

High Tibial Osteotomy

High tibial osteotomy is one of the most commonly performed osteotomy procedures around the knee. It involves making a controlled correction in the upper part of the tibia, or shinbone.

This procedure is frequently considered when varus alignment is associated with excessive loading and cartilage damage on the medial, or inner, side of the knee. By changing the alignment of the tibia, the mechanical axis can be shifted so that weight is distributed more appropriately across the joint.

High tibial osteotomy is not simply a procedure for changing the appearance of a bow-legged knee. The amount and location of correction are calculated according to the patient's individual anatomy and mechanical alignment.

Distal Femoral Osteotomy

In some patients, the alignment problem originates primarily from the femur rather than the tibia. In these cases, a distal femoral osteotomy may be considered.

This procedure involves correcting the lower portion of the thighbone near the knee. It may be used particularly in selected patients with valgus alignment and excessive loading of the lateral compartment of the knee.

Determining whether the correction should be made in the femur, tibia, or occasionally at more than one level requires careful analysis of full-length standing X-rays and the patient's individual anatomy.

How Is an Osteotomy Planned?

Accurate planning is one of the most important stages of osteotomy surgery. The objective is not simply to make the leg appear straighter. The correction must address the mechanical problem responsible for abnormal loading of the knee.

During evaluation, the orthopedic examination assesses knee movement, stability, pain location, previous injuries, activity level, and the condition of the surrounding joints.

Standing X-rays are particularly important because they allow the alignment of the leg under weight-bearing conditions to be evaluated. Full-length leg X-rays may be used to examine the mechanical axis from the hip through the knee to the ankle.

MRI may also be requested when detailed information about cartilage, menisci, ligaments, or other soft tissues is necessary.

How Is Osteotomy Surgery Performed?

During surgery, the bone is carefully cut at the predetermined location and corrected according to the preoperative plan. Depending on the type of osteotomy, the correction may involve opening or closing a controlled wedge in the bone.

Once the desired alignment has been achieved, the bone is stabilized with appropriate fixation, commonly using a plate and screws. This fixation maintains the correction while the bone heals.

The exact surgical technique varies according to the patient's deformity, bone structure, cartilage condition, and the location of the required correction.

What Is the Goal of Knee Osteotomy?

The primary goal is to improve the distribution of forces across the knee while preserving the patient's natural joint. By reducing excessive load on the damaged compartment, osteotomy aims to improve function and reduce symptoms in appropriately selected patients.

Another important objective is to delay the need for knee replacement when this is realistic and clinically appropriate. This can be particularly relevant for younger or physically active patients with localized joint damage.

However, osteotomy cannot guarantee that knee replacement will never be necessary. Degenerative changes can continue over time, and future treatment depends on the progression of the joint condition.

Osteotomy or Knee Replacement?

Osteotomy and knee replacement are fundamentally different operations. Osteotomy aims to preserve the natural knee joint by changing alignment and redistributing load. Knee replacement involves replacing damaged joint surfaces with prosthetic components.

Osteotomy may be considered when damage is concentrated in a specific part of the knee and the remaining joint is sufficiently preserved. Knee replacement may be more appropriate when arthritis is advanced and affects multiple areas of the joint.

Choosing between these treatments requires an individual assessment. The most appropriate operation depends on the pattern of arthritis, alignment, age, activity level, range of motion, symptoms, and expectations of the patient.

Recovery After Osteotomy

Recovery after osteotomy is different from recovery after a simple knee arthroscopy because the bone needs time to heal in its corrected position.

Patients may need crutches during the early recovery period. The amount of weight that can be placed on the operated leg is determined according to the type of osteotomy, fixation, bone quality, and progression of healing.

Follow-up X-rays are used to monitor bone healing. As recovery progresses, weight bearing and activity can be increased according to the surgeon's recommendations.

Rehabilitation focuses on maintaining knee movement, controlling swelling, restoring muscle strength, and gradually returning to normal walking and daily activities.

When Can I Return to Work After an Osteotomy?

Return to work depends greatly on the patient's occupation. Someone who works at a desk may be able to return earlier than a patient whose job requires prolonged standing, walking, lifting, climbing, or other physically demanding activities.

Rather than using the same timeline for every patient, return to work should be planned according to bone healing, pain control, mobility, and the physical demands of the job.

Can I Return to Sports After Knee Osteotomy?

Returning to sports is possible for many appropriately selected patients, but the timing and level of activity vary considerably. Bone healing must first progress adequately, followed by recovery of knee motion, muscle strength, balance, and functional control.

Low-impact activities can generally be introduced before demanding sports. The decision to return to running, competitive sports, or high-impact activities should be individualized according to clinical and radiographic recovery.

What Are the Risks of Osteotomy?

Osteotomy is a major orthopedic procedure and, like all surgery, has potential risks. These may include infection, blood clots, delayed bone healing, failure of the bone to heal, irritation from fixation materials, stiffness, nerve or blood vessel injury, loss of correction, and persistent symptoms.

The individual risk profile depends on factors such as general health, smoking, bone quality, the degree of correction required, previous surgery, and the specific technique used.

The expected benefits, possible limitations, and potential risks should therefore be discussed individually before surgery.

If you have persistent knee pain and have been told that you have bow-legged or knock-kneed alignment, cartilage damage, or arthritis affecting mainly one side of the knee, it is important to determine whether the alignment of your leg contributes to the problem.

A detailed orthopedic assessment can evaluate the location of cartilage damage, mechanical alignment, knee stability, range of motion, activity level, and previous treatments. When necessary, standing and full-length leg X-rays can be used to analyze the mechanical axis and plan possible correction.

For appropriately selected patients, osteotomy can form part of a joint-preserving knee surgery strategy. The objective is to select a treatment based on the patient's individual knee rather than applying the same surgical solution to every patient with knee pain.

Frequently Asked Questions About Osteotomy

What does osteotomy mean?

Osteotomy is a surgical procedure in which a bone is carefully cut and repositioned to correct alignment or improve the distribution of mechanical forces across a joint.

Why is osteotomy performed around the knee?

Knee osteotomy is generally performed to correct abnormal leg alignment and reduce excessive loading on a damaged compartment of the knee while preserving the natural joint.

What is a high tibial osteotomy?

High tibial osteotomy is a procedure in which the upper part of the tibia is corrected. It is commonly considered in selected patients with varus alignment and predominantly medial compartment knee damage.

What is a distal femoral osteotomy?

Distal femoral osteotomy corrects alignment through the lower part of the femur. It may be considered when the deformity originates from the femur, particularly in selected patients with valgus alignment.

Does osteotomy cure knee arthritis?

Osteotomy does not eliminate arthritis or regenerate all damaged cartilage. Its purpose is to improve joint mechanics by reducing excessive stress on the affected part of the knee.

Can osteotomy delay knee replacement?

In appropriately selected patients, osteotomy may help preserve the natural knee and delay the need for joint replacement. However, future knee replacement cannot be ruled out because arthritis may continue to progress.

How long does the bone take to heal after osteotomy?

Bone healing varies between patients and depends on the type of osteotomy, fixation, bone quality, general health, and other individual factors. Follow-up examinations and X-rays are used to monitor healing before activity is progressively increased.

Is osteotomy suitable for every patient with knee arthritis?

No. Osteotomy is most useful in carefully selected patients. The location and severity of arthritis, leg alignment, knee stability, range of motion, activity level, and overall health must be evaluated before deciding on treatment.
