Knee replacement surgery, also known as knee arthroplasty, is a common procedure aimed at alleviating pain and restoring function in severely diseased knee joints. This comprehensive guide by Acibadem Health Point is designed to provide you with authoritative, research-backed information about knee replacement surgery.
Understanding Knee Replacement
What is Knee Replacement Surgery?
Knee replacement surgery involves removing damaged or diseased parts of the knee joint and replacing them with artificial components, typically made of metal and plastic. The goal is to relieve pain, correct deformity, and help you resume normal activities.
Types of Knee Replacement
There are several types of knee replacement surgeries, including:
- Total Knee Replacement (TKR): Replaces the entire knee joint.
- Partial Knee Replacement (PKR): Replaces only the damaged part of the knee joint.
- Revision Knee Replacement: A second surgery to replace a worn-out or failed knee implant.
Benefits of Knee Replacement
- Pain Relief: Alleviates severe knee pain that limits your daily activities.
- Improved Mobility: Restores the function and movement of the knee joint.
- Enhanced Quality of Life: Allows you to return to normal activities and improve your overall well-being.
The Procedure
Pre-Surgery Preparation
Before undergoing knee replacement surgery, several steps are taken to ensure you are well-prepared:
- Medical Evaluation: A thorough medical history and physical examination.
- Imaging Tests: X-rays and MRI scans to assess the extent of knee damage.
- Pre-operative Instructions: Guidance on medications, diet, and pre-surgery exercises.
During the Surgery
Knee replacement surgery typically takes about 1-2 hours and involves the following steps:
- Anesthesia: Administering spinal, epidural, or general anesthesia.
- Incision: Making an incision over the knee to access the joint.
- Removal of Damaged Tissue: Removing damaged cartilage and bone.
- Implant Placement: Inserting the artificial knee components.
- Closure: Sewing the incision and applying a sterile bandage.
Post-Surgery Care
After the surgery, you will be closely monitored and guided through the recovery process:
- Pain Management: Medications to manage post-operative pain.
- Physical Therapy: Exercises to strengthen the knee and improve mobility.
- Follow-Up Visits: Regular check-ups to monitor healing and progress.
Potential Risks and Complications
While knee replacement surgery is generally safe, it carries certain risks and complications, including:
- Infection: Though rare, infections can occur around the surgical site.
- Blood Clots: Deep vein thrombosis (DVT) is a potential risk.
- Implant Issues: Loosening, wear, or failure of the implant may require revision surgery.
Long-Term Outcomes
The success rate of knee replacement surgery is high, with most patients experiencing significant pain relief and improved function. The longevity of the implant can vary, but many last 15-20 years or more.
