Knee pain is one of the most common musculoskeletal complaints, particularly among adults over the age of 50. While many individuals find temporary relief through non-surgical treatments such as physiotherapy, medications, or injections, persistent knee pain can significantly restrict mobility and affect overall quality of life. In such cases, knee replacement surgery is a well-established and effective solution.
Orthopaedic surgeons are often asked multiple questions by patients considering this procedure. Understanding the process, recovery, and outcomes helps patients make informed decisions with confidence.
What Is Knee Replacement Surgery?
Knee replacement surgery, medically termed knee arthroplasty, involves removing damaged cartilage and bone from the knee joint and replacing them with artificial components. These prosthetic implants are designed to replicate natural knee movement, reduce pain, and improve function.
There are two main types of procedures:
Total Knee Replacement (TKR): Replacement of both the femoral and tibial joint surfaces, and sometimes the kneecap.
Partial Knee Replacement (PKR): Replacement of only the damaged compartment of the knee.
Who Is a Suitable Candidate?
Not all knee pain requires surgery. Knee replacement is typically recommended for patients with advanced osteoarthritis or other severe joint conditions who experience chronic pain, joint deformity, and significant difficulty performing daily activities despite conservative treatment. Diagnosis is confirmed through clinical examination and imaging tests such as X-rays or MRI scans.
What Is the Ideal Age for Surgery?
There is no fixed age for knee replacement. Most patients undergoing Total Knee Replacement Surgery in Delhi are between 60 and 80 years old. However, with improvements in implant design and surgical techniques, younger patients with severe disability may also be considered. Younger individuals should be aware that revision surgery may be required later in life due to implant wear.
How Long Do Knee Implants Last?
Modern knee implants are designed to last 15 to 20 years or longer. Longevity depends on factors such as body weight, activity level, implant design, and surgical technique. Patients are advised to avoid high-impact activities to prolong implant life.
Recovery and Rehabilitation:
Recovery varies among individuals, but most patients begin walking with support within 24 to 48 hours. Hospital stay typically lasts 2 to 4 days, with return to routine activities in 4 to 6 weeks. Full recovery and maximum benefit are usually achieved within 3 to 6 months. Dedicated physiotherapy is essential for restoring strength and flexibility.
Pain and Safety:
Postoperative pain is effectively managed with modern anesthesia and pain-control protocols. Many patients report that surgical pain is far less severe than the chronic pain experienced before surgery. Knee replacement is considered a safe procedure, with complications such as infection or blood clots being relatively rare when proper care is taken.
Life After Total Knee Replacement Surgery in Delhi:
While the artificial knee may not feel exactly like a natural joint, most patients enjoy significant pain relief and improved mobility. Minor sensations such as clicking or mild stiffness may occur initially but usually diminish over time.
Role of an Expert Orthopaedic Surgeon:
Choosing an experienced Orthopaedic Surgeon Delhi plays a vital role in achieving successful outcomes. Proper surgical planning, patient education, and structured rehabilitation ensure long-term satisfaction and improved quality of life.
