Knee replacement surgery also known as knee arthroplasty is a life-changing orthopedic procedure designed to relieve pain and restore mobility in patients suffering from severe knee joint problems. As one of the most commonly performed joint replacement surgeries worldwide, it offers significant benefits to people struggling with chronic arthritis, knee injury, or long-term joint degeneration.
In this guide, we’ll explore everything you need to know about knee replacement surgery, including its benefits, types, recovery process, and how to find a qualified surgeon.
What Is Knee Replacement Surgery?
Knee replacement surgery involves removing the damaged or worn-out surfaces of the knee joint and replacing them with artificial implants (prostheses) made of metal alloys, high-grade plastics, or ceramics. The goal is to eliminate pain, improve joint function, and enhance the quality of life.
Who Needs a Knee Replacement?
Knee replacement is typically recommended for patients who:
- Suffer from severe osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis.
- Have chronic knee pain and stiffness that limits daily activities.
- Experience swelling and inflammation that doesn’t improve with medications or physical therapy.
- Notice deformities in the knee, such as bowing in or out.
- Have tried all conservative treatments without success.
Types of Knee Replacement Surgeries
There are several types of knee replacement procedures, depending on the patient’s needs:
- Total Knee Replacement (TKR)
Replaces the entire knee joint with artificial components. This is the most common type. - Partial Knee Replacement (PKR)
Only the damaged compartment of the knee is replaced. This is ideal for patients with limited joint damage. - Bilateral Knee Replacement
Both knees are replaced at the same time, often recommended for patients with severe arthritis in both joints. - Revision Knee Replacement
A follow-up surgery to replace or fix a failed knee implant.
The Knee Replacement Surgery Process
Pre-Surgery Evaluation
The process begins with a detailed assessment by your orthopedic surgeon, including X-rays, MRIs, and blood tests to determine the severity of joint damage.
Surgical Procedure
Performed under general or spinal anesthesia, the surgery typically takes 1–2 hours. Damaged bone and cartilage are removed, and the prosthetic components are securely fixed.
Hospital Stay
Most patients stay in the hospital for 2–4 days post-surgery.
Recovery and Rehabilitation
Recovery from knee replacement surgery varies but generally follows this timeline:
- Week 1–3: Walking with a walker, managing swelling, and beginning physical therapy.
- Week 4–6: Transition to a cane, improve knee strength, and regain range of motion.
- Month 3–6: Resume daily activities; some may return to low-impact sports.
- 1 Year: Full recovery and maximum joint function achieved.
Tip: A structured physiotherapy plan is critical for optimal recovery.
Risks and Complications
Like any surgical procedure, knee replacement carries potential risks, including:
- Infection
- Blood clots
- Implant loosening or wear
- Nerve damage
- Limited range of motion
However, with modern techniques and skilled surgeons, complications are rare and manageable.
Benefits of Knee Replacement Surgery
- Long-term pain relief
- Improved mobility
- Enhanced quality of life
- Ability to return to work or recreational activities
- High satisfaction rate among patients
