Why knees wear out
The knee joint is lined with smooth cartilage that allows the bones to glide. In osteoarthritis, this cartilage gradually wears away, so the bones rub against each other. The result is pain, stiffness, swelling and reduced movement. Other causes of knee damage include rheumatoid arthritis, previous injuries and avascular necrosis.
Treatments to try before surgery
- Weight reduction to reduce load on the knee
- Physiotherapy to strengthen the thigh muscles that support the knee
- Pain-relief medicines as prescribed
- Joint injections and aspirations where appropriate
- Walking aids and activity changes
- Arthroscopic (keyhole) procedures for certain mechanical problems
Smita Memorial Hospital's Orthopaedics Department offers joint injections and aspirations, arthroscopic surgery and comprehensive rehabilitation with physiotherapy and pain management.
Signs knee replacement may be the right choice
- Severe knee pain that limits walking, climbing stairs or sleeping
- Pain that continues despite medicines, physiotherapy and other treatment
- Visible deformity such as bowing of the leg
- Stiffness that prevents bending or straightening the knee
- X-rays showing advanced joint damage
Age alone does not decide. What matters most is how much the knee limits your life and whether other treatments have helped.
Who may not be suitable
- People with mild arthritis who are managing well with non-surgical treatment
- Those with an active infection in the knee or elsewhere
- Some people with serious uncontrolled medical conditions, until these are optimised
- Pain that is actually coming from the hip or spine
Computer-navigated knee replacement
In total knee replacement, the damaged surfaces are removed and replaced with implants. Correct alignment of the implants helps the knee function smoothly and last longer. Smita Memorial Hospital's Orthopaedics Department performs total knee, hip and elbow replacements using computer-navigated arthroplasty, with advanced implants. Surgery is performed in the hospital's operation theatres — the hospital was the first in Idukki district to receive Platinum Grade Green OT certification.
Recovery
- Physiotherapy often begins soon after surgery, as advised
- Walking with support starts early; independence increases over the following weeks
- Exercises at home are essential for bending and strength
- Follow wound-care and blood-clot prevention advice
- Most people return to daily activities gradually over the coming months
Myths and facts
- Myth: You must wait until you cannot walk. Fact: Surgery is considered when pain and stiffness seriously limit your life despite other treatments.
- Myth: Recovery means months in bed. Fact: Patients are encouraged to start walking early with support.
- Myth: Knee replacement is only for the very old. Fact: The decision depends on joint damage and symptoms, not age alone.
Preparing for knee replacement
- Pre-operative assessment including blood tests, ECG and anaesthesia review
- Control of diabetes and blood pressure before surgery
- Treating any infection, including dental and urinary infections
- Strengthening exercises before surgery can help recovery
- Arranging the home: a chair with armrests, raised toilet seat, clear pathways
- Planning insurance pre-authorisation for planned surgery
Pain control and anaesthesia
Modern anaesthesia and pain management make knee replacement far more comfortable than many people fear. The anaesthesia team at Smita Memorial Hospital is trained in general, regional and local anaesthesia and plans pain relief during and after surgery, which helps patients begin moving sooner.
A realistic recovery timeline
- First days: walking with a frame or support; bending exercises start
- First weeks: increasing independence at home; wound healing; continuing exercises
- Following weeks: walking longer distances, climbing stairs with growing confidence
- Months: strength and comfort continue to improve
Recovery varies with age, fitness, the condition of the knee before surgery and how consistently exercises are done.
Protecting your new knee
- Continue exercises even after pain settles
- Avoid high-impact activities such as jumping unless your surgeon approves
- Keep a healthy weight
- Prevent falls at home
- Tell doctors and dentists you have a joint replacement before procedures
- Report fever, increasing pain, swelling or redness promptly
