What Is Knee Replacement Surgery?

Knee replacement surgery, also known as knee arthroplasty, is a surgical procedure in which a damaged or severely worn knee joint is replaced with an artificial implant made of metal and plastic components. The procedure is primarily performed to relieve chronic knee pain and restore joint function and mobility. It is commonly recommended for individuals with advanced knee conditions, such as osteoarthritis, rheumatoid arthritis, or joint damage resulting from injury.

How Does a Knee Implant Work?

During knee replacement surgery, the damaged portions of the knee joint are removed and replaced with an artificial joint made from metal and plastic components. These components are designed to replicate the natural movement of a healthy knee, allowing for smoother motion and improved mobility.

Why Undergo Knee Replacement Surgery?

Knee replacement surgery is commonly recommended for individuals experiencing chronic knee pain, severe osteoarthritis, or joint damage caused by injury or disease. When non-surgical treatments—such as physical therapy or pain medications—fail to provide adequate relief, surgery may become a viable option.
The primary goal of knee replacement surgery is to restore joint function and relieve persistent pain that interferes with daily activities.

Signs You May Need Knee Replacement Surgery

You may be a candidate for knee replacement surgery if you experience one or more of the following symptoms:

• Chronic Knee Pain: Persistent pain that does not improve with rest or medication and worsens during activities such as walking or standing

• Stiffness or Limited Range of Motion: Difficulty fully bending or straightening the knee, especially after prolonged sitting or rest

• Swelling and Inflammation: Recurrent or constant swelling around the knee joint, indicating ongoing inflammation

• Grinding or Popping Sensations: Audible or palpable sounds during movement, often caused by cartilage deterioration

• Mobility Problems: Difficulty walking, dependence on assistive devices, or a sensation that the knee may give way

• Impaired Daily Function: Trouble performing routine activities such as climbing stairs, sitting, or standing for extended periods

Causes of Knee Osteoarthritis or Joint Damage

Several factors can contribute to knee joint degeneration, including:

• Aging: Natural wear and tear of cartilage over time, leading to osteoarthritis

• Overuse: Repetitive strain from prolonged standing, heavy lifting, or high-impact activities

• Obesity: Excess body weight increases stress on the knee joints, accelerating cartilage breakdown

• Previous Injury: Trauma such as fractures, ligament tears, or meniscus injuries that lead to long-term joint damage

• Rheumatoid Arthritis: An autoimmune condition that causes chronic joint inflammation and deterioration

• Genetic Factors: A family history of knee or joint disorders

• Abnormal Bone Alignment: Conditions such as bowlegs or knock knees that place uneven pressure on the knee joint

• Bone Disorders: Diseases such as osteoporosis that weaken bone strength and joint stability

Treatment Options for Knee Osteoarthritis

Treatment depends on the severity of the condition and may involve non-surgical or surgical approaches.

Non-Surgical Treatments

Suitable for mild to moderate cases or patients who are not candidates for surgery:

• Lifestyle Modifications: Weight loss and avoidance of high-impact activities to reduce joint stress

• Physical Therapy: Exercises to strengthen surrounding muscles and improve joint flexibility

• Pain Medications: Over-the-counter or prescription medications to help manage pain and inflammation

• Joint Injections: Hyaluronic acid injections to lubricate the joint and improve movement

• Assistive Devices: Knee braces, canes, or walkers to reduce strain and enhance stability

Surgical Treatments

Recommended for advanced cases when conservative treatments are no longer effective:

• Partial Knee Replacement: Replacement of only the damaged portion of the knee while preserving healthy tissue

• Total Knee Replacement: Replacement of the entire knee joint with an artificial prosthesis, typically for severe joint damage

Post-Surgery Care and Recovery

Appropriate postoperative care is essential for optimal recovery and long-term success.

• Pain Management: Temporary discomfort is normal and managed with prescribed medications. Pain typically improves within 1–2 weeks

• Wound Care: Keep the surgical incision clean and dry, following all instructions for dressing changes and hygiene

• Physical Therapy: Rehabilitation usually begins within 24 hours to restore strength, mobility, and joint flexibility

• Walking Aids: Crutches, walkers, or canes may be required initially and gradually discontinued as mobility improves

• Swelling Control: Elevating the leg and applying ice packs can help reduce swelling during the early recovery phase

• Nutrition: A balanced diet rich in protein and essential nutrients supports tissue healing and recovery

• Follow-Up Visits: Regular follow-up appointments with the surgeon ensure proper healing and allow early detection of complications

Recovery Timeline

Most patients begin to notice significant improvement within one month after surgery. With consistent physical therapy and proper postoperative care, many individuals are able to return to normal daily activities within 6 to 12 weeks, depending on their overall health and recovery progress.
