Knee replacement is not a one-size-fits-all procedure. Modern orthopaedic surgery offers several approaches tailored to the pattern of arthritis, patient age, activity goals, and overall health. Here is an overview of the main types available in Lucknow.
Total Knee Replacement (TKR)
Total knee replacement replaces all three compartments of the knee — medial, lateral, and patellofemoral — with metal and polyethylene components. It is the most common procedure for advanced tricompartmental arthritis.
- Best for widespread cartilage loss across the knee
- Corrects significant deformity and restores alignment
- Proven long-term outcomes with modern implant designs
Partial Knee Replacement (PKR)
Partial knee replacement replaces only the damaged compartment, preserving healthy bone and ligaments. It suits patients with arthritis limited to one part of the knee who meet strict selection criteria.
- Smaller incision and often faster initial recovery
- Preserves more natural knee mechanics
- Requires intact ligaments and localized disease
Bilateral Knee Replacement
When both knees are severely affected, bilateral replacement may be planned — either both knees in one sitting (simultaneous) or one knee at a time with staged surgery (sequential). The choice depends on medical fitness and rehabilitation support.
Minimally Invasive Knee Replacement
Minimally invasive techniques use smaller incisions and muscle-sparing approaches to reduce soft-tissue trauma. Early mobilisation and reduced postoperative pain are potential benefits when performed by experienced surgeons.
Robotic-Assisted Knee Replacement
Robotic systems help the surgeon plan implant positioning with greater precision using preoperative imaging and real-time feedback during surgery. Accurate alignment may improve implant longevity and functional outcomes in selected cases.
Choosing the Right Option in Lucknow
The best type of knee replacement depends on your X-ray findings, ligament stability, age, activity level, and medical conditions. Dr. Kumar Deepak at The OrthoVision Clinic and Remedy Medicity, Lucknow, evaluates each patient individually to recommend the most appropriate surgical approach.
Frequently Asked Questions
Is partial knee replacement as durable as total replacement?
In well-selected patients, partial replacement can provide excellent long-term results. If arthritis spreads to other compartments later, conversion to total replacement may be needed.
Is robotic knee replacement better than conventional surgery?
Robotic assistance enhances precision in planning and implant placement. Outcomes still depend heavily on surgeon experience, patient selection, and rehabilitation.
Can both knees be replaced at the same time?
Simultaneous bilateral replacement is possible in medically fit patients with adequate home support. Staged surgery is preferred when comorbidities or recovery concerns exist.
How long do knee implants last?
Modern implants often last 15 to 20 years or longer. Implant longevity depends on alignment, activity level, body weight, and implant type.
