Knee Osteotomy

Knee osteotomy is a surgery that fixes the knee joint. It helps patients with knee arthritis or deformities. The surgery cuts and reshapes bones to move weight off the damaged area.

This surgery is for younger, active people with arthritis on one side of the knee. It spreads the weight evenly. This can ease symptoms, slow arthritis, and delay a total knee replacement.

The main goal is to fix the knee’s alignment. This reduces pain and improves movement. It helps patients live better lives and do their daily activities again.

What is Knee Osteotomy?

Knee osteotomy is a surgery that aims to fix the knee’s alignment. It helps to spread out the weight-bearing forces. This is done to ease pain and improve how the knee works.

This surgery is for those with knee osteoarthritis or deformities on one side of the joint. It’s a way to correct issues like bowlegs or knock-knees.

Definition and Purpose of Knee Osteotomy

Knee osteotomy involves cutting and reshaping bones to align the knee better. It’s done to move weight away from the damaged area. This helps the healthier part of the knee to handle more weight.

This can reduce pain and improve joint stability. It might also delay the need for a total knee replacement.

Types of Knee Osteotomy Procedures

There are two main types of knee osteotomy procedures:

1. High Tibial Osteotomy (HTO): This is for bowlegs. It involves cutting the upper tibia to realign it.
2. Distal Femoral Osteotomy (DFO): This is for knock-knees. It involves cutting the lower femur to realign it.

Both High Tibial Osteotomy and Distal Femoral Osteotomy are good for correcting knee deformities. The choice depends on the patient’s anatomy and the surgeon’s preference.

Candidates for Knee Osteotomy

Knee osteotomy is a surgery for certain knee problems. It’s key to check if someone is right for this surgery.

Indications for Knee Realignment Surgery

The main reasons for knee osteotomy are:

• Genu Varum Correction: People with bowlegs (genu varum) might need this surgery. It aims to fix the knee’s alignment and spread out the weight better.
• Genu Valgum Correction: Those with knock-knees (genu valgum) can also get help from this surgery. It corrects the knee’s alignment and boosts its function.
• Knee Joint Preservation: Sometimes, this surgery is used to keep the knee joint natural. It’s good for younger, active people with arthritis in one part of the knee.

Contraindications and Risk Factors

Even though knee osteotomy helps many, there are things to think about:

• Advanced knee arthritis in many parts of the joint
• Severe knee instability or weak ligaments
• Not much movement in the knee joint
• Smoking, which can slow healing and raise risks
• Being overweight, which can stress the knee more after surgery

It’s vital to have a detailed check-up with an orthopedic surgeon. They’ll look at age, activity level, health, and knee condition to decide if surgery is right.

High Tibial Osteotomy (HTO)

High tibial osteotomy is a surgery to fix the knee’s alignment. It helps those with medial compartment osteoarthritis and varus deformity. This surgery can ease pain, boost function, and might delay the need for a total knee replacement.

The most used method is the medial opening wedge osteotomy. The surgeon cuts the tibia’s top part and opens it to make a wedge. Bone graft material fills this gap to keep the bone in place. A plate and screws hold the osteotomy stable.

People who get high tibial osteotomy usually fit certain criteria:

Recovery from high tibial osteotomy involves slowly getting back to normal activities. Most can start low-impact exercises in 3-4 months. It takes 6-12 months to fully return to sports and high-impact activities. Many patients see lasting pain relief and function improvement for years post-surgery.

Distal Femoral Osteotomy (DFO)

Distal femoral osteotomy is a surgery to fix valgus deformity and osteoarthritis in the knee’s lateral compartment. It realigns the femur to shift weight-bearing forces. This helps reduce pain in the affected area.

Procedure Overview and Techniques

In a distal femoral osteotomy, the surgeon cuts the lower femur end to correct the deformity. Then, they use plates and screws to hold the bone in place. The exact method depends on the deformity’s severity and the patient’s body.

The table below outlines the key steps involved in a typical distal femoral osteotomy procedure:

Recovery and Rehabilitation after DFO

After a distal femoral osteotomy, patients start a detailed rehab program. This helps regain strength, range of motion, and function in the knee. For a few weeks, they might not bear full weight to heal properly.

Physical therapy is key in this recovery. It includes strengthening exercises, joint mobilization, and learning to walk again. Following the recommended rehab plan and keeping up with the surgical team is vital for the best results. DFO can greatly improve pain and function for those who are good candidates.

Knee Osteotomy vs. Knee Replacement

When looking at treatments for knee arthritis, patients and doctors consider knee osteotomy and total knee replacement. Both aim to ease pain and improve function. Yet, they have different methods and results.

Knee osteotomy is a way to keep the knee healthy by realigning bones. It shifts weight off the damaged area. This is good for younger, active people who want to avoid knee replacement. It also means a quicker recovery.

On the other hand, total knee replacement removes and replaces the damaged parts with artificial ones. It’s for older patients with severe arthritis. While it offers lasting relief, it takes longer to recover and might limit certain activities.

Comparison of Benefits and Limitations

Factors to Consider in Decision-Making

Choosing between knee osteotomy and total knee replacement involves several factors. These include:

• Age and activity level of the patient
• Severity and location of knee arthritis
• Overall health and medical history
• Patient preferences and goals for treatment

The right choice depends on a detailed evaluation by an orthopedic surgeon. They will suggest the best option based on individual needs and circumstances.

Preparing for Knee Osteotomy Surgery

Getting ready for knee osteotomy surgery is key for a good outcome and easy recovery. It’s important for patients to work closely with their orthopedic surgeon and healthcare team. This ensures they are both physically and mentally prepared for the surgery.

The first step is a detailed medical evaluation. This may include:

After the medical evaluation, the orthopedic surgeon will create a surgical plan just for you. This plan will outline the type of osteotomy procedure, the surgical technique, and any pre-operative preparations needed.

To get ready physically and mentally for surgery, patients should:

• Start a pre-operative exercise program to strengthen muscles and improve flexibility
• Eat a balanced diet rich in nutrients to support healing and recovery
• Lose weight if necessary to reduce stress on the knee joint
• Quit smoking to reduce the risk of complications and improve healing
• Manage stress and anxiety through relaxation techniques and support from loved ones

By following their pre-operative preparation plan and talking openly with their healthcare team, patients can prepare well for knee osteotomy surgery. This helps ensure a smoother recovery process.

Recovery and Rehabilitation after Knee Osteotomy

After a knee osteotomy, a detailed post-operative recovery and rehabilitation protocol is key for healing and getting back to normal. The time it takes to recover and reach milestones can differ based on the surgery and individual factors. But, most people can expect to slowly get back to their usual activities over a few months.

Timeline and Milestones of Recovery

The usual recovery period after knee osteotomy includes:

Physical Therapy and Exercise Programs

Physical therapy is a big part of the rehabilitation protocol after knee osteotomy. A skilled physical therapist will help you with exercises to improve range of motion, strength, and function. This might include:

• Range of motion exercises
• Strengthening exercises for the quadriceps, hamstrings, and hip muscles
• Balance and proprioception training
• Gait training and functional activities

Pain Management and Wound Care

Managing pain control is vital for a smooth recovery and successful rehab. Patients might use a mix of medications, like acetaminophen, NSAIDs, and opioids (if needed), as their surgeon advises. Using ice and elevating the leg can also help with pain and swelling.

It’s important to take care of the wound to avoid infection and help it heal. Keep the incision clean and dry, and change dressings as told by your healthcare team. If you notice any signs of infection, like more pain, redness, or discharge, tell your healthcare team right away.

Long-Term Outcomes and Success Rates of Knee Osteotomy

Knee osteotomy has shown great results over time. It helps many patients with knee pain by improving function and reducing pain. Most people can do more daily activities and enjoy physical activities again.

Many patients are very happy with the results. They say they feel less pain and live better lives. This shows how effective knee osteotomy can be.

The results of knee osteotomy can last for years. This depends on the patient’s age, weight, and how bad the osteoarthritis is. Often, it can delay the need for a full knee replacement by years.

Going to regular check-ups and following the rehabilitation plan is key. This helps keep the benefits of the surgery going for longer.

Knee osteotomy is not a cure for everyone. But it’s a good option for those who want to ease symptoms and improve knee function without a full knee replacement. Always talk to a skilled orthopedic surgeon before making a decision. They can help decide if knee osteotomy is right for you.
