Everything You Need to Know About High Tibial Osteotomy

Imagine waking up every morning, and the first thing you feel is pain in your knee. Getting out of bed, climbing stairs, and walking to the kitchen, each step is a reminder that something is wrong. For millions of people across India, this is daily life with knee arthritis.

Most people assume the only answer is a knee replacement. But here’s what many patients don’t know: if you catch it early enough, there is another way.

High Tibial Osteotomy (HTO) is a surgical procedure that can relieve your knee pain, slow down arthritis progression, and help you avoid or at least significantly delay a total knee replacement. It’s not a new procedure, but it’s one that is often overlooked.

This article explains everything you need to know about joint preservation for arthritis, written in plain language so you can have an informed conversation with your doctor.

What Is Knee Arthritis and Why Does It Happen?

Arthritis of the knee is not just “wear and tear.” It is the gradual breakdown of the cartilage, the smooth, rubbery cushion that lines the inside of your knee joint. When cartilage wears away, the bones begin rubbing against each other. That friction causes pain, swelling, stiffness, and, over time, deformity.

In India, osteoarthritis (the most common type) affects roughly 15% of people over the age of 60. But it doesn’t only affect the elderly. Active adults in their 30s and 40s, especially those with sports injuries, obesity, or a bow-legged or knock-kneed alignment, can develop early-stage arthritis much sooner.

Common Causes of Knee Arthritis

Malalignment of the leg – Bow legs (varus) or knock knees (valgus) places uneven stress on one side of the knee
Previous knee injuries – A torn meniscus or ACL injury that wasn’t treated properly
Obesity – Every extra kilogram adds roughly 4 kg of force across the knee joint
Age-related changes – Cartilage naturally thins over time
Family history – Genetics does play a role
Heavy physical labour – Common in manual workers, farmers, and construction workers

Early arthritis treatment in Thane, focused on knee preservation, can often delay surgery, even when consulting the best doctor for knee replacement becomes necessary later.

Warning Signs You Should Not Ignore

Many people brush off early knee pain as “tiredness” or “old age.” But these signs deserve attention:

Pain on one side of the knee (usually the inner side in bow-legged patients)
Morning stiffness that eases within 30 minutes of moving around
Swelling after activity or by the end of the day
A grinding or creaking sensation inside the knee
Difficulty fully straightening or bending the knee
Limping or favouring one leg while walking
Knee pain that gets worse when going downstairs more than upstairs

If you are younger than 55–60 and experiencing these symptoms, you may be an ideal candidate for joint preservation surgery, not replacement. Timely arthritis treatment in Thane from the best knee orthopedic surgeon may help preserve your natural joint before considering care at the best hospital knee replacement centre.

How Is Knee Arthritis Diagnosed?

A good orthopaedic surgeon will not rely only on an X-ray. Diagnosis involves a clinical examination, appropriate imaging, and understanding the grade of arthritis.

Imaging Investigations

Investigation	What It Shows
Standing X-ray (full leg)	Overall leg alignment, joint space narrowing
MRI of the knee	Cartilage condition, meniscus health, ligaments
CT scan (sometimes)	Bone anatomy for precise surgical planning
DEXA scan	Bone density important before surgery

Arthritis is graded on the Kellgren-Lawrence scale from Grade 1 (mild) to Grade 4 (severe/bone-on-bone). HTO is most effective in Grade 2 and Grade 3, where meaningful cartilage is still present. Accurate diagnosis is essential because early arthritis treatment in Thane by the best knee orthopedic surgeon may prevent unnecessary surgery, even before consulting the best doctor for knee replacement.

What Is High Tibial Osteotomy (HTO)?

Let’s break the name down: High = performed near the top of the shin bone. Tibial = the tibia (shin bone). Osteotomy = a surgical cut in the bone.

In simple terms, the surgeon makes a precise cut in your shin bone, realigns it slightly, and holds it in the new position with a metal plate and screws. This shifts your body weight away from the damaged, arthritic side of your knee and onto the healthier side.

Think of it like re-balancing a car’s tyres when the tread on one side wears out faster. You are correcting the root cause of the alignment, not just treating the symptom.

Types of HTO

Opening Wedge HTO – A small wedge-shaped gap is created on the inner side of the tibia and held open with a bone graft and plate. Most commonly performed today.
Closing Wedge HTO – A small piece of bone is removed from the outer side to close the gap. Less common now.

Who Is the Right Candidate for HTO?

You May Be a Good Candidate If:

You are between 30 and 60 years of age
You have medial compartment arthritis (inner side) with bow-legged alignment
Your pain is localised to one side of the knee
You have Grade 2 or Grade 3 arthritis (not end-stage)
You are active and want to return to sports or physical work
You have good ligament stability and no significant cartilage loss on the other side

HTO May Not Be Suitable If:

You have Grade 4 (bone-on-bone) arthritis across the whole knee
You are significantly overweight (high BMI can affect outcomes)
You have inflammatory arthritis, such as rheumatoid arthritis
You have ligament instability or prior failed knee surgery
You smoke, which significantly slows bone healing

Other Joint Preservation Options

HTO is often part of a broader strategy. Depending on your condition, your surgeon may also recommend:

Arthroscopic debridement – Cleaning up damaged tissue inside the knee (for early-stage cases)
Cartilage repair procedures – Microfracture, OATS, or ACI (Autologous Chondrocyte Implantation)
PRP injections – Regenerative injections to stimulate healing (adjunct therapy, not a standalone cure)
Unloader knee brace – Specially designed to shift load away from the damaged compartment
Combined HTO with cartilage repair – Often done together for better long-term outcomes

The best knee orthopedic surgeon will always prioritise joint preservation and knee preservation strategies before recommending surgery at the best hospital knee replacement facility.

What Happens During HTO Surgery?

HTO is performed under spinal or general anaesthesia. Here is a step-by-step overview:

The surgeon makes a small incision below the inner side of the knee
Using specialised guides, a precise cut is made partway through the tibia
The cut is carefully opened to the calculated angle (determined from pre-operative X-rays)
A bone graft (your own bone or a synthetic substitute) is placed in the gap
A metal plate and screws are fixed to hold the correction in place
The incision is closed, and a dressing is applied

The procedure typically takes 60 to 90 minutes.

Recovery: What to Expect Week by Week

Timeframe	What Happens
Day 1–2	Walking with crutches, pain managed with medication
Week 1–2	Discharge home, physiotherapy begins (gentle exercises)
Week 4–6	Partial weight-bearing, swelling reduces significantly
Week 8–12	Full weight-bearing, bone consolidating on X-ray
Month 3–4	Returning to desk work, light activity
Month 6	Most patients return to normal daily activities
Month 12+	Return to sports and strenuous activity

Important: Individual recovery varies. Smokers, diabetics, and patients with low bone density may take longer to heal.

Exercises and Lifestyle Advice

After Surgery (Phase-Wise)

Early phase: Ankle pumps, gentle knee bends, quad sets, done in bed
Mid phase: Straight leg raises, stationary cycling, pool walking
Late phase: Squats (within pain limits), step-ups, resistance training

Daily Habits That Protect Your Knee

Maintain a healthy weight – Losing even 5 kg can reduce knee load significantly
Low-impact exercise: Swimming, cycling, and yoga are ideal
Avoid sitting cross-legged on the floor for prolonged periods
Wear good footwear – Flat, shock-absorbing soles
Strengthen your quadriceps and hamstrings – These muscles act as shock absorbers

What to Eat

Anti-inflammatory foods: turmeric, ginger, omega-3-rich foods (fish, walnuts, flaxseeds)
Calcium and vitamin D: dairy, ragi, sunlight exposure
Reduce processed foods and refined sugar, as they promote inflammation

Prevention: Can You Slow Down Arthritis Before It Starts?

Get your leg alignment checked early: Bow legs or knock knees can be corrected in childhood
Treat sports injuries properly: Do not ignore a meniscus or ACL tear
Avoid excessive squatting and kneeling in daily work if you already have pain
Lose weight if you are overweight: This single change has the most impact on knee health
Exercise consistently but wisely: Build muscle without stressing the joint

HTO vs Total Knee Replacement: What’s the Difference?

This is the question most patients ask. Here is a clear side-by-side comparison:

Feature	High Tibial Osteotomy (HTO)	Total Knee Replacement (TKR)
Age group	30–60 years	Usually 60+ years
Arthritis severity	Grade 2–3 (partial)	Grade 3–4 (severe)
What is preserved	Your natural knee	Replaced with an implant
Activity level post-op	High sports possible	Moderate
Implant required	Plate & screws only	Full knee implant
Can TKR be done later?	Yes, HTO does not prevent it	N/A
Recovery time	6–12 months	3–6 months

The key advantage of HTO: you keep your natural knee. And if arthritis progresses years later, a knee replacement is still an option.

When Should You See an Orthopaedic Surgeon?

Do not wait until you are limping or completely unable to walk. Seek expert opinion if:

Knee pain has persisted for more than 6 weeks despite rest and medication
Pain is interfering with your work, sleep, or daily activities
You notice a visible deformity, or your knees are bowing outward
You are below 60 years old and have been told you need a knee replacement
You have had a previous knee injury that never fully healed
Pain medication is no longer working as well as it used to

If you are in Thane, Mumbai, or the surrounding areas, consulting an orthopaedic surgeon who specialises in joint preservation and complex knee reconstruction can help you understand all your options, including whether HTO is right for you.

Frequently Asked Questions (FAQ)

Is High Tibial Osteotomy a major surgery?

It is a moderately significant surgery done under anaesthesia, but it is not as extensive as a total knee replacement. Most patients are discharged within 2–3 days and recover well with proper physiotherapy.

How long does the benefit of HTO last?

Studies show that in well-selected patients, the results of HTO last 10 to 15 years or more. After that, some patients may need a knee replacement, but by then, they are older and better suited for it.

Is HTO painful after surgery?

There will be discomfort in the first few weeks, managed with pain medication. Most patients find the post-operative pain manageable, and it gradually reduces over 4–6 weeks.

Can I play sports after HTO?

Yes, this is actually one of the biggest advantages over knee replacement. Many patients return to jogging, cycling, trekking, and even cricket within 9–12 months.

Will the metal plate and screws cause problems?

The plate and screws are made of medical-grade titanium and are designed to stay permanently. They do not usually need removal unless they cause local irritation, which is uncommon.

Is HTO available in Thane / Mumbai?

Yes. Experienced orthopaedic surgeons in Thane and Mumbai perform HTO regularly. It requires careful pre-operative planning and surgical expertise, so choose a surgeon with specific experience in complex knee reconstruction.

How much does a High Tibial Osteotomy cost in India?

The cost varies depending on the hospital, surgeon’s experience, and implant used. As a general guide, HTO in Mumbai or Thane typically ranges from ₹1.5 lakh to ₹3.5 lakh, including the implant. Many insurance policies and government health schemes do cover this procedure.

What is the difference between HTO and arthroscopy?

Arthroscopy is a keyhole procedure used to clean or repair tissue inside the knee; it does not correct alignment. HTO addresses the root cause by correcting the mechanical axis of the leg. They can be combined.

Can HTO be done on both knees?

Yes, but usually not at the same time. If both knees are affected, surgeries are typically staged 3–6 months apart.

What happens if I don’t treat my knee arthritis?

Without treatment, arthritis typically worsens over time. The cartilage continues to wear away, the deformity increases, and eventually, the only option left is a total knee replacement. Early intervention gives you more choices and better long-term outcomes.

A Note from Our Practice

Arthritis does not have to mean a lifetime of pain or an inevitable knee replacement. With the right diagnosis, the right timing, and the right surgical approach, many patients in their 40s and 50s regain a functioning, pain-free knee and go on to live very active lives.

Joint preservation is both a philosophy and a commitment. It means looking beyond quick fixes and thinking about what will serve you best over the next 20–30 years.
