Everything You Need to Know About Knee Replacement Surgery

Knee pain can significantly impact your quality of life, making everyday tasks like walking, climbing stairs, or even standing for long periods extremely difficult. For people suffering from severe arthritis or joint damage, knee replacement surgery often becomes a necessary solution. This blog will guide you through the basics, benefits, and recovery process of this life-changing procedure.

What is Knee Replacement Surgery?

Knee replacement surgery, also known as knee arthroplasty, is a medical procedure in which a damaged or worn-out knee joint is replaced with an artificial implant. The goal of the surgery is to relieve pain, improve mobility, and restore the function of the knee joint. It is typically recommended for individuals who have tried other treatments like physical therapy, medications, and injections without success.

Who Needs Knee Replacement Surgery?

This procedure is commonly performed on patients suffering from:

• Osteoarthritis
• Rheumatoid arthritis
• Post-traumatic arthritis
• Severe knee injuries

If your knee pain persists despite non-surgical treatments and starts affecting your daily activities, your orthopedic surgeon may suggest knee replacement surgery as the best option.

Types of Knee Replacement

There are mainly two types of knee replacement procedures:

1. Total Knee Replacement (TKR): This is the most common type, where both sides of the knee joint are replaced.
2. Partial Knee Replacement (PKR): Only the damaged portion of the knee is replaced, which may lead to a quicker recovery and better flexibility.

Your doctor will help you decide which option is best based on the condition of your knee, overall health, and lifestyle.

The Surgery Process

Knee replacement surgery usually takes about 1-2 hours. It’s performed under spinal or general anesthesia. During the procedure:

• The damaged cartilage and bone are removed.
• Metal and plastic implants are used to recreate the joint surface.
• The new components are fixed in place with bone cement or a press-fit technique.

Post-surgery, patients usually stay in the hospital for 2 to 4 days depending on their recovery speed.

Recovery and Rehabilitation

Recovery from knee replacement surgery varies by person but generally includes:

• Physical therapy starting the day after surgery.
• Gradual increase in walking and strength exercises.
• Full recovery typically takes 3 to 6 months.

Following your rehabilitation plan strictly is crucial for a successful outcome. Many patients report significant pain relief and improved mobility after recovery.

Benefits of Knee Replacement Surgery

• Long-lasting pain relief
• Improved quality of life
• Greater mobility and independence
• High success rate (over 90% of patients experience good results)

Risks and Considerations

Like any major surgery, knee replacement surgery carries some risks such as infection, blood clots, or implant failure. However, these risks are relatively rare, especially when performed by experienced surgeons and followed by proper post-op care.

Conclusion

Knee replacement surgery can be a life-changing decision for those living with chronic knee pain. With advances in medical technology and surgical techniques, it has become a highly effective and safe procedure. If knee pain is holding you back from enjoying life, consult a qualified orthopedic specialist to see if knee replacement surgery is the right path for you.
