Complete Guide to Knee Arthroscopy for ACL, Meniscus & Ligament Injuries in Pune

1. What is Knee Arthroscopy?

Knee arthroscopy is a minimally invasive surgical technique used to diagnose and treat issues within the knee joint. Using a small camera (called an arthroscope) inserted through tiny incisions, the surgeon can see inside the knee joint and identify damaged tissue, torn ligaments, or cartilage. In many cases, arthroscopy allows for repair or removal of damaged tissue with smaller incisions, leading to reduced pain, fewer complications, and faster recovery times compared to traditional open surgery.

2. When is Knee Arthroscopy Recommended?

Knee arthroscopy is commonly recommended for individuals suffering from injuries to the ACL, meniscus, or other ligaments. Some of the most common scenarios where knee arthroscopy is suggested include:

• ACL Tears: The ACL is one of the major ligaments in the knee. A tear often occurs during sports activities involving sudden changes in direction or jumping.
• Meniscus Tears: The meniscus is a cartilage that acts as a cushion between the thighbone and shinbone. Tears can occur from twisting motions or trauma.
• Ligament Injuries: Injuries to other ligaments, such as the MCL (medial collateral ligament) or PCL (posterior cruciate ligament), can also be treated using arthroscopic surgery.

If you’ve experienced any of the following symptoms, knee arthroscopy might be an appropriate solution:

• Persistent pain in the knee joint
• Swelling and inflammation that doesn’t go away
• Limited range of motion in the knee
• A popping or clicking sound when you move the knee
• Inability to bear weight on the affected knee

3. Types of Injuries Treated with Knee Arthroscopy

Knee arthroscopy is highly effective for treating various knee injuries, including:

a. ACL Injuries
The anterior cruciate ligament is one of the most crucial stabilizing structures in the knee. It helps prevent the tibia (shinbone) from sliding forward and provides stability during movements like running, jumping, and pivoting. A complete ACL tear often requires reconstruction surgery, which can be performed via arthroscopy. This procedure uses either a graft from your own body or a donor graft to replace the damaged ligament.

b. Meniscus Tears
The meniscus acts as a shock absorber between the femur (thighbone) and tibia (shinbone). Meniscus tears are common and can occur due to trauma or age-related wear and tear. Arthroscopy can be used to trim or repair the torn meniscus, depending on the severity of the injury. For more severe tears, a full meniscectomy or meniscus repair may be required.

c. Ligament Injuries (MCL, PCL)
Injuries to the MCL (medial collateral ligament) and PCL (posterior cruciate ligament) are also treatable with arthroscopy. Both ligaments provide stability to the knee joint, and an injury can cause instability or discomfort. Repair of these ligaments through arthroscopy helps restore knee function and relieve pain.

4. Benefits of Knee Arthroscopy

Knee arthroscopy offers several advantages over traditional open surgery, including:

• Smaller Incisions: The procedure only requires small incisions, leading to minimal scarring.
• Faster Recovery: Due to the minimally invasive nature of arthroscopy, recovery times are significantly shorter compared to open surgery. Many patients are able to return to normal activities in a matter of weeks.
• Reduced Pain: Smaller incisions result in less trauma to surrounding tissues, meaning less pain during the recovery process.
• Lower Risk of Complications: With reduced incisions and a more controlled environment, the risk of complications such as infection is minimized.

5. The Knee Arthroscopy Procedure: Step-by-Step

Knee arthroscopy is a relatively straightforward procedure, typically performed under local or general anaesthesia. The steps involved are as follows:

• Preparation: The surgeon will clean and sterilize the knee area. The patient is positioned in a way that gives the surgeon optimal access to the knee joint.
• Incisions: The surgeon makes a few small incisions around the knee joint to insert the arthroscope and surgical instruments.
• Visualisation: The camera is inserted, and the surgeon can view the inside of the knee on a monitor. This allows for precise diagnosis and treatment of the damaged area.
• Treatment: Depending on the injury, the surgeon will either trim or repair the damaged tissue or ligament. Tools are used to remove debris or perform repairs, such as stitching a torn ligament.
• Closing: After the procedure, the incisions are closed with sutures, and the knee is bandaged.

6. Recovery After Knee Arthroscopy

While knee arthroscopy is less invasive than traditional surgery, it still requires some recovery time. The recovery process includes:

• Rest: Immediately after surgery, you’ll need to rest and keep your knee elevated to reduce swelling.
• Physical Therapy: Rehabilitation and physiotherapy are crucial for restoring strength and mobility to the knee joint. Dr. Sahil Lombar will guide you through a personalized rehabilitation plan to ensure a smooth recovery.
• Post-Surgery Care: You may be instructed to use crutches or a brace to protect the knee during the initial stages of recovery.

Most patients return to light activities within 2 to 3 weeks, while more intense physical activities may take 6 to 12 weeks, depending on the type of surgery and the individual's healing process.
