Robotic Partial Knee Replacement in Faridabad

July 21, 2026

Knee arthritis does not always damage the entire knee joint. In many patients, particularly during the earlier stages of osteoarthritis, the damage remains limited to just one part, or compartment, of the knee. In such cases, replacing the complete knee joint may not always be necessary.

Robotic partial knee replacement in Faridabad offers a more targeted solution. Instead of removing and replacing the entire knee, the procedure treats only the damaged compartment while preserving healthy bone, cartilage, ligaments and surrounding tissues.

With robotic assistance, the orthopaedic surgeon can develop a personalised surgical plan, evaluate the patient’s knee movement and position the implant with a high level of precision. The technology assists the surgeon throughout the procedure; it does not independently perform the operation.

Patients looking for an experienced robotic knee replacement surgeon in Faridabad can consult Dr Deepak Kumar Mishra, an orthopaedic surgeon with more than 26 years of reported experience in knee replacement, hip replacement, arthroscopy and related orthopaedic procedures. His official profiles describe expertise in primary and revision knee and hip replacement surgeries, partial knee replacement and robotic joint replacement.

Understanding the Different Parts of the Knee

The knee is generally divided into three compartments:

1. Medial compartment: The inner side of the knee
2. Lateral compartment: The outer side of the knee
3. Patellofemoral compartment: The area between the kneecap and thigh bone

Osteoarthritis may begin in only one of these compartments. The medial compartment is commonly affected because it carries a significant proportion of body weight during standing and walking.

When arthritis is limited to one compartment and the remaining parts of the knee are healthy, a surgeon may consider partial knee replacement rather than total knee replacement.

What Is a Partial Knee Replacement?

Partial knee replacement, also known as unicompartmental knee replacement, is a surgical procedure in which only the damaged part of the knee is resurfaced and replaced with an implant.

During the procedure, the surgeon removes a carefully measured amount of damaged bone and cartilage from the affected compartment. A specially designed implant is then positioned to restore smooth movement and reduce painful contact between the bones.

Unlike total knee replacement, partial knee replacement normally preserves:

• Healthy compartments of the knee
• More of the patient’s natural bone
• The anterior and posterior cruciate ligaments, when healthy
• Undamaged cartilage
• Natural knee mechanics to a greater extent

This bone- and ligament-preserving approach may help the operated knee feel more natural for appropriately selected patients.

What Is Robotic Partial Knee Replacement?

Robotic partial knee replacement combines the principles of unicompartmental knee replacement with computer-assisted planning and robotic technology.

Before or during the surgery, the system creates a detailed representation of the patient’s knee anatomy. Depending on the robotic platform being used, this may involve preoperative imaging or real-time mapping of the joint.

The surgeon uses this information to plan:

• The exact area of damaged bone to be removed
• The size of the implant
• The position and alignment of the implant
• The balance of the knee throughout its range of motion
• The amount of healthy bone and tissue that should be preserved

During surgery, robotic assistance helps the surgeon work within the predefined treatment area. The surgeon remains in control of the operation at every stage.

Clinical literature indicates that robotic assistance can improve the accuracy and precision of partial knee replacement procedures, although results still depend on correct patient selection, surgical expertise, rehabilitation and individual health factors.

Robotic Partial Knee Replacement vs Total Knee Replacement

The correct procedure depends on the extent and pattern of arthritis.

Robotic Partial Knee Replacement

It may be considered when:

• Arthritis is limited to one compartment
• The remaining cartilage is reasonably healthy
• The knee ligaments are functional
• The knee is stable
• The deformity is correctable
• Pain is localised to a particular part of the knee

Total Knee Replacement

It may be recommended when:

• Arthritis involves two or three knee compartments
• There is severe deformity
• The knee is significantly unstable
• Ligaments are badly damaged
• Inflammatory arthritis has affected the whole joint
• Pain and stiffness are widespread

A partial knee replacement should not be chosen simply because the incision may be smaller or recovery may be quicker. It is beneficial only when the patient’s arthritis pattern and knee condition meet the required criteria.

Who May Be Suitable for Robotic Partial Knee Replacement?

A person experiencing knee pain should undergo a complete orthopaedic assessment before being considered for surgery.

A suitable candidate may have:

• Osteoarthritis limited mainly to one knee compartment
• Pain located on the inner or outer side of the knee
• Pain while walking, standing or climbing stairs
• Difficulty getting up from a chair
• Knee stiffness after rest
• Reduced ability to perform routine activities
• Limited benefit from medication, physiotherapy or injections
• Good ligament stability
• A reasonable range of knee movement
• A correctable bow-legged or knock-kneed deformity

Partial knee replacement is commonly considered for localised osteoarthritis when non-surgical treatment has not provided sufficient relief. Patients with stable ligaments, good movement and arthritis confined to a limited area are generally more suitable candidates.

Age alone does not determine eligibility. The decision is based on the location of arthritis, activity level, ligament condition, knee stability, bone quality and the patient’s overall health.

Who May Not Be Suitable?

Robotic partial knee replacement may not be appropriate when a patient has:

• Arthritis throughout the knee
• Severe inflammatory arthritis
• Major ligament damage
• Significant knee instability
• Severe or fixed deformity
• Active infection
• Poor skin condition around the knee
• Advanced disease in the other knee compartments
• Certain neuromuscular conditions
• Uncontrolled medical problems

In these situations, total knee replacement or another treatment may provide a more reliable outcome.

Symptoms That Should Be Evaluated by a Knee Specialist

Consult a knee doctor if you experience:

• Persistent pain on one side of the knee
• Pain that affects walking or standing
• Difficulty climbing or descending stairs
• Swelling that repeatedly returns
• Stiffness after sitting for long periods
• A grinding or catching sensation
• Reduced knee movement
• Pain that interrupts sleep
• Difficulty performing household or professional activities
• Dependence on pain-relieving medication
• Increasing bow-legged or knock-kneed appearance

Early consultation does not necessarily mean that surgery will be advised. It allows the doctor to diagnose the stage of arthritis and recommend appropriate measures before the condition progresses.

Diagnosis Before Robotic Partial Knee Replacement

The assessment normally includes a detailed medical history and physical examination.

The surgeon may evaluate:

• Exact location of pain
• Knee alignment
• Range of motion
• Ligament stability
• Walking pattern
• Muscle strength
• Swelling and tenderness
• Response to previous treatments

Investigations may include:

Weight-Bearing X-Rays

Standing X-rays help identify loss of joint space, bone spurs, deformity and the compartment affected by arthritis.

Special Knee Views

Additional views may help the surgeon evaluate the kneecap and individual knee compartments.

MRI Scan

An MRI may be advised in selected cases to assess cartilage, ligaments, meniscus and other soft tissues. It is not necessary for every patient.

Blood Tests

Tests may be required to rule out infection, inflammatory arthritis or medical problems before surgery.

Pre-Anaesthesia Evaluation

The patient may undergo blood investigations, an ECG, chest assessment and specialist clearance depending on age and medical history.

Benefits of Robotic Partial Knee Replacement

For a properly selected patient, potential benefits may include:

1. Preservation of Healthy Bone

Only the damaged compartment is resurfaced, allowing more natural bone to remain intact.

2. Preservation of Healthy Ligaments

When suitable, important knee ligaments are retained, which may support more natural movement and joint awareness.

3. Personalised Surgical Planning

Robotic systems allow planning based on the patient’s individual anatomy rather than relying only on standard measurements.

4. Precise Implant Positioning

Robotic assistance helps the surgeon execute the planned bone preparation and implant placement accurately.

5. Smaller Surgical Exposure

The operation generally requires less exposure than a total knee replacement, although incision size varies.

6. Less Disruption of Healthy Tissue

Because only the affected compartment is treated, there may be less disturbance to healthy bone and soft tissues.

7. Potentially Faster Initial Recovery

Many suitable patients recover functional movement sooner than after total knee replacement. Recovery, however, differs between individuals.

8. More Natural Knee Movement

Preserving healthy compartments and ligaments may allow the knee to feel more natural during daily activities.

9. Reduced Blood Loss

Partial replacement generally involves less bone preparation than total knee replacement, which may contribute to lower blood loss in selected cases.

10. Easier Future Conversion, When Required

If arthritis later progresses to other parts of the knee, a partial replacement may be converted to a total knee replacement. This is still a revision procedure and requires careful surgical planning.

How Is Robotic Partial Knee Replacement Performed?

The exact process varies according to the robotic system and the patient’s condition, but the general stages include:

Step 1: Anaesthesia

The surgery may be performed under spinal, regional or general anaesthesia based on the anaesthetist’s assessment.

Step 2: Surgical Access

The surgeon makes an incision and examines the knee to confirm that arthritis is limited to the planned compartment.

Step 3: Knee Mapping and Registration

The patient’s anatomy is registered with the robotic system. This helps match the actual knee with the digital surgical plan.

Step 4: Assessment of Alignment and Ligament Balance

The surgeon moves the knee through different angles to assess alignment, stability and soft-tissue balance.

Step 5: Personalised Planning

The implant position is adjusted virtually according to the patient’s anatomy and functional knee movement.

Step 6: Removal of Damaged Bone

The surgeon uses robotic assistance to prepare only the planned damaged area while protecting healthy structures.

Step 7: Implant Placement

The implant is positioned in the treated compartment, and its movement and stability are evaluated.

Step 8: Closure

After confirming satisfactory knee movement and implant placement, the incision is closed and a dressing is applied.

The robot acts as an advanced surgical tool. It does not replace the surgeon’s judgement, experience or control.

Recovery After Robotic Partial Knee Replacement

Recovery depends on the patient’s age, fitness, muscle strength, health conditions, severity of arthritis and commitment to rehabilitation.

First 24 Hours

Many patients are encouraged to stand and begin walking with assistance once medically stable. Physiotherapy may start on the day of surgery or the following day.

Hospital Stay

Some patients may be discharged after a short stay, while others need additional observation. Discharge depends on pain control, walking ability and overall medical fitness.

First Two Weeks

The main goals are to:

• Control swelling
• Protect the surgical wound
• Improve knee bending and straightening
• Walk safely with support
• Perform prescribed exercises
• Prevent blood clots and other complications

Two to Six Weeks

Patients generally work toward:

• Improved walking
• Reduced dependence on walking aids
• Better muscle strength
• Increased knee movement
• Resumption of light daily activities

Six to Twelve Weeks

Many patients experience meaningful functional improvement during this period. Full recovery may take longer depending on individual progress and occupational demands.

Patients must follow their surgeon’s advice rather than comparing their recovery with another person’s experience.

Physiotherapy After Surgery

Physiotherapy plays a major role in achieving a good outcome.

A rehabilitation programme may include:

• Ankle pump exercises
• Quadriceps activation
• Straight-leg raises
• Knee bending and straightening
• Assisted walking
• Balance training
• Gait correction
• Stair-climbing practice
• Progressive muscle strengthening
• Functional exercises

Patients should not perform aggressive exercises or use gym equipment without professional guidance during early recovery.

Risks and Limitations

Robotic partial knee replacement is a major surgical procedure and carries possible risks, including:

• Infection
• Blood clots
• Bleeding
• Anaesthesia-related problems
• Persistent pain
• Knee stiffness
• Nerve or blood-vessel injury
• Implant loosening or wear
• Fracture around the implant
• Progression of arthritis in untreated compartments
• Need for revision or conversion to total knee replacement

Robotic technology can assist precision, but it cannot eliminate every surgical risk or guarantee a specific result.

Patients should discuss expected benefits, limitations, implant longevity and alternatives with their surgeon before making a decision.

How Long Does a Partial Knee Implant Last?

The life of an implant varies from patient to patient. It depends on:

• Implant positioning
• Bone quality
• Body weight
• Activity level
• Implant design
• Progression of arthritis
• Rehabilitation
• Overall knee alignment
• Injury or infection

Modern partial knee replacements may function for many years, but no implant should be considered permanent. Regular follow-up helps the surgeon monitor implant condition and the health of the remaining knee.

Frequently Asked Questions

1. Is robotic partial knee replacement better than conventional surgery?

Robotic assistance may improve planning and execution accuracy, but “better” depends on correct patient selection, surgeon expertise and the condition of the knee. Not every patient needs robotic or partial replacement.

2. Does the robot perform the knee operation?

No. The orthopaedic surgeon controls and performs the procedure. The robotic system assists with planning, measurements and accurate execution.

3. Is partial knee replacement suitable for severe arthritis?

It may be suitable only if severe damage is still confined to one compartment and the ligaments and other compartments remain healthy. Widespread arthritis generally requires total knee replacement.

4. Can both knees undergo partial replacement?

Yes, in selected patients, but each knee must be evaluated separately. Arthritis may affect different compartments or stages in each knee.

5. How soon can I walk after surgery?

Many patients begin assisted walking within the first day after surgery, depending on medical stability and the surgeon’s rehabilitation protocol.

6. Is robotic partial knee replacement painful?

Postoperative discomfort is expected, but pain is managed with medication, regional anaesthesia techniques, cold therapy and physiotherapy.

7. How long does recovery take?

Many patients return to routine activities over several weeks. Functional improvement often continues for a few months. Recovery varies according to individual health and rehabilitation.

8. Can partial knee replacement be converted to total knee replacement?

Yes. If arthritis progresses or the implant fails, conversion may be possible. It is considered revision surgery and should be planned by an experienced joint replacement surgeon.

9. What is the cost of robotic partial knee replacement in Faridabad?

The cost varies based on the hospital, implant, robotic platform, room category, investigations, length of stay and medical condition. A personalised estimate can be provided after consultation.
