Tibial osteotomy is a realignment surgery done on the shin bone near the knee to shift body weight away from the damaged part of the joint. In orthopedic practice, this most often refers to a high tibial osteotomy (HTO), which is commonly used in selected patients who have knee pain on one side of the joint, especially the inner or medial side, along with bow-leg alignment and early or moderate unicompartmental arthritis. [1][2]
In my practice, I often explain to patients that tibial osteotomy is not the same as knee replacement. The goal is different. Instead of replacing the knee joint, the aim is to correct the alignment of the leg so that pressure moves away from the worn area of cartilage and toward the healthier side of the knee. For the right patient, this can reduce pain, improve function, and sometimes delay the need for joint replacement. [1][3]
For Bangladeshi patients and families, this topic can feel confusing because many people hear about knee replacement far more often than osteotomy. But in younger or more active patients with specific alignment problems, tibial osteotomy may be an important option worth understanding.
What Is Tibial Osteotomy?
An osteotomy means cutting and reshaping a bone to improve alignment. In a tibial osteotomy around the knee, the upper part of the tibia is carefully cut and repositioned so the leg carries weight in a better line. [1][2]
Why alignment matters
When the knee is not properly aligned, one side of the joint may bear too much load with every step. Over time, this can increase cartilage wear, pain, and progression of arthritis. In a person with varus alignment or a bow-leg pattern, the inner side of the knee often takes more pressure. A high tibial osteotomy can shift part of that load toward the healthier outer side. [1][3]
I usually explain this in simple terms: if all your body weight keeps pressing on the damaged side of the knee, the pain often continues. If we can safely improve the line of weight-bearing, the knee may work more efficiently.
Who May Need a Tibial Osteotomy?
This surgery is not for every patient with knee pain. It is usually considered only after careful evaluation.
Patients who may be suitable candidates
- Younger or middle-aged active adults
- Patients with pain mainly on one side of the knee
- Bow-leg alignment with medial compartment overload
- Early or moderate unicompartmental osteoarthritis
- Some patients with meniscal deficiency, cartilage damage, or ligament-related alignment problems
- Patients who are not ideal candidates for immediate total knee replacement [1][3][4]
In Bangladesh, I commonly see patients who remain quite active in daily life even when they have knee pain. They may need to use stairs often, walk on uneven roads, travel long distances, squat for daily activities, or continue work that places repeated load on the knees. In selected cases, alignment-correcting surgery may offer a joint-preserving option.
Who May Not Be a Good Candidate?
Not every painful knee benefits from tibial osteotomy. When I evaluate a patient, I look carefully at the whole knee, the alignment, activity level, age, body weight, ligament status, and the condition of the joint surfaces.
Situations where tibial osteotomy may be less suitable
- Advanced arthritis affecting multiple compartments of the knee
- Severe stiffness or poor knee motion
- Significant inflammatory arthritis
- Major instability that is not being addressed appropriately
- Poor bone quality or other medical issues affecting healing
- Patients unable to follow the rehabilitation plan [1][2]
This is one reason I do not advise patients to decide based only on one X-ray image or a social media video. Proper patient selection is one of the most important parts of a successful outcome.
Why Is Tibial Osteotomy Done?
Common reasons for surgery
- To reduce pain from one-sided knee overload
- To improve knee alignment
- To protect healthier cartilage
- To improve walking tolerance and daily function
- To delay progression of arthritis in selected patients
- To support other knee procedures in some cases, such as ligament or cartilage-related surgery [1][3][4]
One important point I want Bangladeshi patients to understand is that tibial osteotomy is usually not a “last option.” It is a targeted option for a specific type of problem. The question is not whether it sounds smaller or bigger than knee replacement. The real question is whether the alignment problem and knee condition match the procedure.
Types of Tibial Osteotomy
The most commonly discussed type is high tibial osteotomy.
High tibial osteotomy
This is done in the upper part of the tibia near the knee. It is often used when the inner side of the knee is worn and the leg is in varus alignment. [1][2]
Open-wedge and closing-wedge techniques
There are different technical methods, including opening-wedge and closing-wedge osteotomy. In simple terms, the surgeon changes the bone shape to correct alignment and then stabilizes it with metal hardware such as a plate and screws while healing occurs. [1][3]
The exact technique depends on the patient’s alignment, bone shape, associated pathology, and the surgical plan. Patients do not need to memorize the technical details, but they should understand the purpose: shifting load away from the painful compartment.
How I Evaluate a Patient Before Tibial Osteotomy
When I assess a patient for possible tibial osteotomy, I do not look only at pain. I assess the full mechanical picture of the limb.
Important parts of evaluation
- History of pain, swelling, and activity limits
- Exact location of knee pain
- Bow-leg or other alignment pattern
- Range of motion and ligament stability
- Meniscus and cartilage status
- Weight-bearing X-rays for alignment assessment
- Sometimes MRI or other imaging depending on the case
