Total Knee Replacement in Mumbai by Dr. Mayur Rabhadiya

Total Knee Replacement in Mumbai

Quick answer: Total knee replacement is an operation for advanced knee-joint damage when pain, stiffness, deformity or loss of function substantially affects daily life and suitable non-surgical treatment no longer provides adequate relief. The operation resurfaces the damaged joint surfaces. It does not remove the entire knee.

This page explains the total knee replacement procedure, preparation, hospital care, rehabilitation, risks and long-term expectations. For doctor selection and credentials, visit Knee Replacement Surgeon in Mumbai.

What is total knee replacement?

Total knee replacement, also called total knee arthroplasty, replaces damaged bearing surfaces at the ends of the femur and tibia with metal components. A medical-grade polyethylene insert sits between them. The undersurface of the kneecap is assessed and may be resurfaced when clinically appropriate.

The main aims are to reduce arthritis-related pain, improve stability and walking, correct clinically important deformity when appropriate and improve daily function. A replaced knee is not identical to a natural knee, and surgery cannot guarantee complete pain relief, unrestricted bending or a fixed implant lifespan.

When may total knee replacement be appropriate?

The decision should combine symptoms, functional limitation, examination findings, standing X-rays, response to suitable treatment, medical health and informed patient preference. An X-ray grade or the phrase “bone-on-bone” is not enough by itself.

• Pain that substantially limits walking or routine activity

• Rest or night pain

• Progressive stiffness or loss of movement

• Bow-leg or knock-knee deformity affecting function

• Instability or recurrent giving way

• Loss of independence despite appropriate treatment

• Arthritis affecting several knee compartments

Patients who may not yet need surgery should review non-surgical knee arthritis treatment in Mumbai. If a proposed operation remains uncertain, use the knee replacement second-opinion pathway.

Total or partial knee replacement?

Total knee replacement is generally more appropriate when arthritis affects multiple compartments, deformity is substantial, ligament function is unsuitable for partial replacement or symptoms are not confined to one compartment.

Partial knee replacement may be considered when arthritis is genuinely limited to one compartment and the remaining cartilage, ligaments, movement and deformity satisfy the required criteria. Read about partial knee replacement in Mumbai.

Assessment and surgical planning

Clinical examination

Assessment includes gait, alignment, swelling, tenderness, range of movement, fixed deformity, ligament stability, muscle strength, patellar tracking and whether the hip, spine or another condition may be contributing to symptoms.

Imaging

Weight-bearing knee X-rays help show the distribution of arthritis, deformity, bone loss and whether the disease pattern suits total or partial replacement. MRI is not routinely required before every total knee replacement. It is useful only when it is likely to clarify a specific diagnostic or structural uncertainty.

Medical preparation

Diabetes, anaemia, heart or kidney disease, smoking, previous blood clots, infection risk, nutrition, medicines and other health factors are reviewed before surgery. Modifiable problems should be addressed before an elective procedure where possible.

Components used in total knee replacement

• Femoral component: a metal component covering the prepared end of the thigh bone.

• Tibial component: a metal base placed on the prepared upper surface of the shin bone.

• Polyethylene insert: a medical-grade plastic bearing between the metal components.

• Patellar component: a component that may be used on the undersurface of the kneecap according to the clinical plan.

Implant selection depends on anatomy, bone quality, ligament condition, stability needs, implant design, fixation requirements, compatibility with the chosen surgical system and the surgeon's experience. The newest or most expensive implant is not automatically the most suitable.

Robotic planning and the surgical approach

Robotic assistance and the surgical approach are different parts of the operation. Robotic systems may support planning, measurements, bone preparation, alignment assessment and execution of the selected implant position. They do not diagnose the patient or perform surgery independently.

The mini-subvastus approach describes how the surgeon reaches the knee and aims to preserve the quadriceps mechanism in appropriately selected patients. It should not be promised solely on the basis of incision size.

How total knee replacement is performed

The exact sequence varies with anatomy, implant system and operative findings, but a primary procedure generally includes:

1. Anaesthesia and positioning

2. Sterile preparation of the leg

3. Surgical exposure of the knee

4. Inspection of the joint

5. Preparation of the damaged femoral and tibial surfaces

6. Trial component placement

7. Assessment of alignment, stability, movement and patellar tracking

8. Final implant insertion and fixation

9. Bleeding control and wound closure

10. Recovery-room monitoring and early rehabilitation when medically safe

The plan may be modified if bone quality, ligament condition, anatomy or unexpected findings differ from what was anticipated.

Anaesthesia and pain management

Anaesthesia may involve regional anaesthesia, general anaesthesia or a combination selected by the anaesthetist according to the patient's health, medicines and surgical requirements.

Multimodal pain management may include local infiltration, oral and intravenous medicines, selected nerve blocks, ice, swelling control and early movement. Pain can be actively managed, but a painless operation or identical pain experience cannot be guaranteed.

Preparation before surgery

• Medical history and medicine review

• Blood tests and other investigations based on health status

• Anaesthesia assessment

• Diabetes, blood-pressure and anaemia optimisation

• Planning for blood-thinning medicines

• Skin, dental or infection review when indicated

• Smoking cessation and nutrition support where relevant

• Preoperative strengthening and walking-aid practice

• Home and caregiver planning

Body mass index alone should not be used as an automatic barrier to assessment. Weight, body habitus, medical risk, nutrition, mobility and expected benefit should be considered together.

Hospital stay and discharge

Many medically stable patients begin assisted standing and walking early after surgery. Hospital stay varies with medical health, pain control, wound condition, one-knee or bilateral surgery, safe mobility, stair requirements, home support and complications.

Discharge should be based on readiness rather than a promised number of days. Before leaving hospital, the patient should understand medicines, blood-clot prevention, wound care, exercises, walking-aid use, warning symptoms and follow-up arrangements.

Rehabilitation and recovery

Rehabilitation commonly includes circulation exercises, knee movement, quadriceps activation, safe transfers, walking with an aid, stair training, progressive strengthening, balance work and gradual return to daily activity.

Recovery varies with preoperative strength and movement, deformity, surgical complexity, pain, swelling, medical health, confidence, home support and complications. Progress should be judged by clinical and functional milestones rather than a fixed calendar promise.

For a structured timeline, read the knee replacement recovery guide.

Expected benefits and limitations

In an appropriately selected patient, total knee replacement is intended to reduce arthritis pain and improve function, stability and independence. It may also correct deformity when this forms part of a safe reconstruction.

It cannot guarantee:

• A completely natural-feeling knee

• Complete absence of pain or swelling

• Unlimited bending

• Comfortable squatting or cross-legged sitting

• Return to every sport or occupation

• A fixed implant lifespan

• No complications or future surgery

Risks of total knee replacement

Potential complications include infection, blood clots, pulmonary embolism, bleeding, wound problems, stiffness, persistent pain, instability, fracture, nerve or blood-vessel injury, reduced movement, implant loosening or wear, medical complications and the possible need for further surgery.

Individual risk varies with medical conditions, smoking, nutrition, weight, previous operations, deformity, bone quality and procedural complexity. Careful selection and preparation reduce avoidable risk but cannot make risk zero.

Long-term care of a knee replacement

Long-term follow-up may include clinical review and X-rays according to symptoms, implant type and the surgeon's plan. Patients should maintain general health, preserve muscle strength, manage body weight where relevant and seek assessment for new pain, swelling, instability or reduced function.

Implant survival is not the same as a symptom-free knee. Longevity varies with implant design and fixation, alignment, activity, body weight, bone quality, infection risk and biological factors.

When to seek urgent assessment after surgery

Contact the treating team promptly or seek emergency care for increasing wound discharge, fever with a hot or rapidly swelling knee, new severe calf swelling, chest pain, breathlessness, sudden loss of movement after injury, new weakness or numbness, or rapidly worsening illness.

Book a total knee replacement consultation

Bring recent standing knee X-rays, older imaging, prescriptions, injection or physiotherapy records, current medicines and relevant medical reports.

Book an orthopedic consultation with Dr. Mayur Rabhadiya. Assessment determines whether total knee replacement is appropriate and which plan is safest.
