Knee Replacement Surgery : Everything you need to know

Knee replacement surgery, also known as knee arthroplasty, is a common procedure for those suffering from severe knee pain and disability, typically due to arthritis or injury. This comprehensive guide will provide detailed information about knee replacement surgery, including the types, procedures, pre-and post-operative care, recovery, potential risks, and the factors to consider when choosing to undergo surgery either in your home country or abroad.

 

What is Knee Replacement Surgery?

Knee replacement surgery involves removing damaged cartilage and bone from the surface of the knee joint and replacing them with artificial implants. This procedure can significantly reduce pain and improve mobility for individuals with severe knee joint damage.

Types of Knee Replacement Surgery

1. Total Knee Replacement (TKR)

This is the most common type of knee replacement surgery. It involves replacing the entire knee joint with a prosthesis.

2. Partial Knee Replacement (PKR)

Also known as unicompartmental knee replacement, this procedure replaces only the damaged part of the knee, preserving healthy bone and tissue.

3. Revision Knee Replacement

This procedure is performed to replace an existing knee prosthesis that has worn out or failed.

Who Needs Knee Replacement Surgery?

Knee replacement surgery is typically recommended for individuals with:

• Severe knee pain that limits daily activities
• Chronic knee inflammation and swelling that does not improve with rest or medication
• Knee deformity, such as bowing in or out of the leg
• Failure to improve with other treatments like physical therapy, medications, or injections

The Procedure

1. Pre-Operative Preparation

• Medical Evaluation: Comprehensive health assessment to ensure the patient is fit for surgery.
• Pre-Surgery Education: Information about the procedure, recovery, and rehabilitation.
• Lifestyle Adjustments: Patients may be advised to lose weight, stop smoking, or make other lifestyle changes to enhance recovery.

2. During Surgery

• Anesthesia: General anesthesia or spinal anesthesia is used to ensure the patient is pain-free.
• Incision: A cut is made over the knee to access the joint.
• Bone Preparation: Damaged bone and cartilage are removed.
• Implant Placement: The artificial knee joint is positioned and secured.
• Closure: The incision is closed with stitches or staples.

Recovery and Rehabilitation

1. Immediate Post-Operative Care

• Hospital Stay: Typically lasts 2-3 days.
• Pain Management: Medications are provided to manage post-surgical pain.
• Physical Therapy: Begins within 24 hours to improve mobility and strength.

2. Home Care

• Wound Care: Keeping the incision clean and dry to prevent infection.
• Activity Restrictions: Avoiding high-impact activities and following the surgeon’s guidelines.

3. Long-Term Rehabilitation

• Exercise Program: A structured exercise regimen to restore strength and flexibility.
• Follow-Up Visits: Regular check-ups with the surgeon to monitor progress.

Potential Risks and Complications

• Infection: Can occur at the incision site or within the joint.
• Blood Clots: Deep vein thrombosis (DVT) is a potential risk.
• Implant Problems: Wear and tear, loosening, or dislocation of the prosthesis.
• Nerve Damage: Rare but possible complication.
• Allergic Reactions: To anesthesia or materials used in the prosthesis.

Factors to Consider When Choosing Surgery Location

1. Cost

The cost of knee replacement surgery can vary significantly depending on the country and the healthcare facility. Consider the overall expenses, including travel and accommodation if opting for surgery abroad.

2. Quality of Care

Research the reputation of the surgeons and the quality of healthcare facilities. Accreditation and patient reviews can provide insight into the standard of care.

3. Surgeon’s Expertise

The experience and expertise of the surgeon are crucial for successful outcomes. Look for surgeons with specialized training and extensive experience in knee replacement procedures.

4. Post-Operative Care

Consider the availability and quality of post-operative care and rehabilitation services. Effective recovery often requires close follow-up and access to physical therapy.
