What is Knee Arthroscopy?
Knee arthroscopy is a surgical procedure that allows doctors to examine and treat knee joint problems using a small camera called an arthroscope. The procedure involves making tiny incisions around the knee and inserting specialized instruments to diagnose and repair damaged tissues.
What are the Conditions Treated with Knee Arthroscopy?
Knee arthroscopy is commonly used to treat:
Meniscus Tears: Repairing or removing torn cartilage.
ACL & PCL Injuries: Reconstructing torn ligaments.
Cartilage Damage: Smoothing or repairing cartilage defects.
Loose Bodies Removal: Extracting fragments of bone or cartilage.
Patella Issues: Correcting kneecap alignment problems.
Inflammatory Conditions: Treating synovitis and other joint inflammations.
What are the Benefits of Knee Arthroscopy?
Minimally Invasive: Smaller incisions lead to faster healing.
ACL & PCL Injuries: Reconstructing torn ligaments.
Reduced Pain & Scarring: Less post-operative discomfort compared to open surgery.
Faster Recovery: Most patients resume daily activities within a few weeks.
Accurate Diagnosis: Enables a clear view of the knee joint.
Lower Risk of Complications: Compared to traditional knee surgery.
The Knee Arthroscopy Procedure
Pre-Surgery Preparation
Before undergoing knee arthroscopy, your doctor will:
Conduct a physical examination.
Recommend imaging tests like MRI or X-rays.
Advise stopping certain medications before surgery.
Provide fasting instructions before anesthesia.
Step-by-Step Procedure
1. Anesthesia Administration: Local, regional, or general anesthesia is given.
2. Small Incisions: Tiny cuts are made around the knee.
3. Insertion of Arthroscope: A small camera is inserted to visualize the joint.
4. Repair or Removal: Damaged tissues are treated using specialized instruments.
5. Closure: Incisions are stitched or bandaged.
6. Recovery Monitoring: The patient is observed for a few hours before discharge.
What are the Recovery After Knee Arthroscopy?
Immediate Post-Op Care
Minimally Invasive: Smaller incisions lead to faster healing.
Rest & Ice: Reduces swelling and pain.
Compression Bandage: Supports the knee and prevents excessive movement.
Elevation: Keeps swelling under control.
Rehabilitation & Physical Therapy
First Week: Gentle movements and limited weight-bearing.
2-4 Weeks: Gradual strengthening exercises.
4-6 Weeks: Return to normal activities.
3-6 Months: Full recovery for sports and intense activities.
Tips for Faster Recovery
Follow your doctor’s instructions.
Stick to your physical therapy routine.
Avoid high-impact activities until cleared by your doctor.
Maintain a healthy diet to support healing.
What are the Risks and Complications?
While knee arthroscopy is generally safe, potential risks include:
Infection: Rare but possible.
Blood Clots: Prevented with early movement and compression devices.
Swelling & Stiffness: Managed with physical therapy.
Nerve or Blood Vessel Damage: Extremely rare but possible.
