Knee surgery in Mexicali

What is knee surgery?

Knee surgery is a medical procedure aimed at addressing various issues in the knee joint. This joint is one of the largest and most complex in the body, involving bones, cartilage, muscles, ligaments, and tendons. When the knee is damaged due to injury, wear and tear, or disease, surgery may be required to restore function, reduce pain, and improve mobility.

There are several types of knee surgery depending on the underlying condition, ranging from minor procedures to more extensive reconstructions. The surgery may involve repairing damaged tissues, replacing parts of the knee joint, or even replacing the entire joint with an artificial one. It is often performed when non-surgical treatments like physical therapy, medications, or injections fail to relieve symptoms or improve function.

How is it carried out?

There are various ways to perform knee surgery depending on the specific condition being treated. The three most common types include:

1. Arthroscopic knee surgery

This is a minimally invasive procedure where small incisions are made around the knee joint, and a tiny camera (arthroscope) is inserted to visualize the inside of the joint. Special instruments are then used to repair or remove damaged tissues. Arthroscopy is often used to treat problems like meniscus tears, ligament injuries, and loose cartilage.

Benefits:

• Smaller incisions
• Faster recovery time
• Less pain after the procedure
• Minimal scarring

2. Partial knee replacement

In this surgery, only the damaged part of the knee joint is replaced with artificial parts (prosthetics). This method is less invasive than a total knee replacement and is suitable for patients with damage confined to one part of the knee, often due to osteoarthritis.

Benefits:

• Less bone is removed compared to total knee replacement
• Quicker recovery and rehabilitation
• Often preserves more of the patient’s natural knee motion

3. Total knee replacement

This is a more extensive surgery where the entire knee joint is replaced with prosthetic components made of metal and plastic. It is typically done for patients with severe joint damage, most often due to advanced arthritis or significant injury.

Benefits:

• Relieves chronic knee pain
• Restores mobility and function in severely damaged knees
• Long-lasting results

What are the most common diagnoses that resort to this type of procedure?

The most common reasons for knee surgery include:

• Osteoarthritis: This degenerative joint disease causes the breakdown of cartilage in the knee, leading to pain, stiffness, and loss of function.
• Rheumatoid arthritis: An autoimmune condition that results in inflammation of the knee joint and can cause significant damage over time.
• Meniscus tear: Damage to the cartilage between the knee bones, which can cause pain, swelling, and difficulty moving the knee.
• Ligament injuries: Tears to ligaments such as the ACL (anterior cruciate ligament) or PCL (posterior cruciate ligament), often occurring due to sports injuries or trauma.
• Knee fractures: Breaks in the bones that form the knee joint, requiring surgical intervention to repair or replace parts of the bone.
• Patellar dislocation: A condition where the kneecap (patella) moves out of its normal position, often requiring surgery to realign it.
• Synovitis: Inflammation of the synovial membrane, which lines the knee joint, sometimes necessitating surgical intervention to reduce swelling and pain.

Who are candidates for this procedure?

Candidates for knee surgery typically include individuals who experience severe pain, stiffness, or dysfunction in the knee that interferes with daily activities such as walking, climbing stairs, or getting out of chairs. Most often, they have tried non-surgical treatments like medication, physical therapy, or injections, but without significant improvement. Patients may also have structural damage in the knee that requires surgical repair, such as torn ligaments or damaged cartilage.

How long does this type of procedure take?

The duration of knee surgery varies depending on the type and complexity of the procedure. For example, arthroscopic knee surgery generally takes about 30 minutes to 1 hour, while a partial or total knee replacement may take between 1 to 2 hours. The time may increase if there are complications or if the surgeon needs to perform additional repairs.

Recovery times

Recovery times also vary depending on the type of knee surgery and the patient’s overall health. For minimally invasive procedures like arthroscopy, patients can often return to normal activities within 4 to 6 weeks. Partial knee replacement recovery typically takes around 6 weeks to 3 months, while total knee replacement may require 3 to 6 months or more for full recovery.

Factors such as the patient’s age, physical condition, and adherence to rehabilitation exercises will influence recovery time. Physical therapy is often crucial to help regain strength and mobility in the knee.

Results

The results of knee surgery depend largely on the underlying condition, the type of procedure performed, and the patient’s overall health. Many patients experience significant pain relief and improved mobility after surgery, particularly with total knee replacement, where pain reduction can be dramatic and long-lasting. Arthroscopic surgery can lead to rapid recovery and return to activity, especially in cases of ligament or cartilage repair.

However, results vary depending on the complexity of the condition, and in some cases, patients may require additional treatment or follow-up procedures.
