Knee replacement surgery (also called knee arthroplasty) is a procedure in which damaged cartilage and bone from the knee joint are removed and replaced with artificial implants made of metal and high-grade plastic. It is one of the most successful and commonly performed orthopaedic surgeries worldwide, with a proven track record of relieving pain and restoring mobility.
Dr. Shahrukh Khan is one of the most experienced knee replacement surgeons in Delhi, performing total knee replacement, partial (unicompartmental) knee replacement and revision knee replacement with excellent outcomes and rapid recovery protocols.
Types of Knee Replacement
Total Knee Replacement (TKR): All three compartments of the knee are resurfaced. Most common for advanced osteoarthritis.
Partial (Unicompartmental) Knee Replacement: Only the damaged compartment is replaced. Faster recovery, better range of motion. Suitable for selected patients.
Revision Knee Replacement: Re-do surgery for failed previous replacements due to loosening, infection or wear.
Bilateral Knee Replacement: Both knees replaced in the same surgical session or in staged procedures.
Rapid Recovery Protocol: Dr. Shahrukh uses modern rapid recovery techniques – most patients begin walking within 24 hours of surgery. Hospital stay is typically just 2–3 days.
When Do You Need Knee Replacement?
Severe knee pain that limits daily activities (walking, climbing stairs)
Knee pain at rest or during sleep
Significant knee stiffness or deformity (bow-legged or knock-kneed)
Failure of conservative treatments: physiotherapy, injections, medication
X-ray showing bone-on-bone contact (loss of joint space)
Advanced osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis
The Procedure – What to Expect
Surgery is performed under spinal or general anaesthesia and typically takes 60–90 minutes. The damaged surfaces of the femur (thigh bone), tibia (shin bone), and patella (kneecap) are precisely resurfaced using specially designed implants. A high-grade polyethylene spacer is placed between the implants to provide a smooth, pain-free gliding surface.
Recovery After Knee Replacement
Day 1: Standing and walking with support
Week 1–2: Walking independently with a walker at home
Week 3–6: Return to most daily activities; driving in ~4–6 weeks
Month 3: Most patients fully active; return to light sports
Month 6–12: Full activity including moderate exercise

Frequently Asked Questions
Modern knee implants last 20–25+ years in most patients. Longevity depends on activity level, weight, and implant type. High-quality implants are always used by Dr. Shahrukh Khan.
There is no strict minimum age. The decision is based on severity of arthritis and quality of life, not age. Younger patients may be considered for partial replacement or osteotomy first.
Post-operative pain is managed very effectively with modern multimodal pain protocols. Most patients are surprised by how comfortable they feel within 24–48 hours of surgery.
Yes. Most patients climb stairs within 2–3 weeks of surgery. Full stair function is restored within 6₃38 weeks.
