Orthopedic surgery plays a crucial role in helping people regain mobility, reduce pain, and live healthier, more active lives. While there are many types of orthopedic procedures, knee replacement surgery is by far the most common worldwide. It's a go-to solution for patients suffering from chronic knee pain and stiffness, especially due to age-related joint damage.
At MedHarbour, we regularly see patients who have exhausted all non-surgical treatments and are ready for a long-term solution to reclaim their mobility. Here’s everything you need to know about the most performed orthopedic procedure today.
Why Is Knee Replacement So Common?
The knee joint is one of the largest and most complex joints in the body. It supports most of our body weight and is involved in almost every movement—standing, walking, climbing stairs, and even sitting. Over time, wear and tear on the knee can lead to severe pain and disability.
Osteoarthritis is the most common reason for knee replacement. It’s a degenerative joint disease that breaks down cartilage, leading to bone-on-bone friction, inflammation, and joint stiffness. Other causes include rheumatoid arthritis, previous knee injuries, or post-traumatic arthritis.
With an aging population and an increase in lifestyle-related joint issues, more people are turning to knee replacement as a reliable and lasting solution.
What Happens During Knee Replacement Surgery?
Knee replacement, or total knee arthroplasty, involves removing damaged cartilage and bone from the ends of the femur (thigh bone) and tibia (shin bone). These surfaces are then replaced with artificial components made of metal and high-grade plastic. Sometimes, a portion of the patella (kneecap) is also resurfaced.
There are two types of procedures:
Total knee replacement (TKR): Replacement of the entire knee joint.
Partial knee replacement (PKR): Only the damaged part of the knee is replaced, which may be suitable for patients with damage limited to one section of the knee.
Thanks to advancements in surgical techniques and materials, knee replacements today are more durable and feel more natural than ever before.
What to Expect Before and After Surgery
At MedHarbour, every patient undergoes a detailed evaluation before surgery. This includes X-rays, physical exams, and a discussion about lifestyle, pain levels, and goals. Once surgery is scheduled, we provide pre-operative education to help patients understand the recovery process.
The procedure typically takes 1 to 2 hours and is performed under spinal or general anesthesia. Patients are encouraged to begin moving their knee within 24 hours, and many can return home the same day or after a short hospital stay.
Rehabilitation is a vital part of recovery. Physical therapy helps patients regain strength, flexibility, and range of motion. Most people can resume daily activities within 6 to 12 weeks, although full recovery may take up to six months.
Outcomes and Success Rates
Knee replacement is one of the most successful surgeries in modern medicine. According to global health data, over 90% of patients report a significant improvement in pain and mobility. The implants used today can last 15 to 20 years or longer, depending on lifestyle and activity level.
At MedHarbour, we prioritize not only the technical success of the procedure but also the patient’s long-term quality of life. Our team of experienced orthopedic surgeons, physiotherapists, and rehabilitation specialists work together to ensure the best possible outcomes.
Final Thoughts
Knee replacement surgery remains the most common orthopedic procedure because of the sheer number of people affected by knee joint conditions and the procedure’s high success rate. If chronic knee pain is limiting your lifestyle and non-surgical treatments no longer help, it may be time to explore your options.
