Key Points

• Knee arthroscopy is an effective and minimally invasive method for treating joint injuries.
• This procedure can result in a faster recovery with fewer complications.
• It is essential to consider the associated risks to make informed health decisions.

What is Knee Arthroscopy?

Knee arthroscopy is a minimally invasive surgical procedure that allows doctors to examine and treat knee injuries. It uses advanced technology to provide an internal view of the joint, facilitating both diagnoses and interventions.

Definition and Objectives

Knee arthroscopy involves the insertion of a tiny camera called an arthroscope through small incisions in the skin. This device allows surgeons to directly visualize the inside of the knee on a monitor.

The primary goal of this technique is to diagnose and treat conditions such as ligament injuries, meniscus tears, and other joint problems. This may include repairing damaged tissues or removing loose fragments, thereby improving the patient's function and movement.

Surgical Technique

During arthroscopy, small incisions, typically 0.5 to 1 cm, are made in the knee. Through these incisions, the arthroscope and other specialized surgical instruments are introduced.

The procedure can be performed under local or general anesthesia, depending on the complexity of the case. Surgeons use saline solutions to inflate the joint, facilitating visualization and intervention.

Recovery is quick compared to open surgeries, and many patients can return to their daily activities within a few weeks.

Benefits of Knee Arthroscopy

Knee arthroscopy offers multiple significant benefits, highlighting its ability to facilitate a faster recovery and provide a precise diagnosis. This minimally invasive technique is beneficial for both the patient and the doctor.

Accelerated Recovery

One of the main benefits of knee arthroscopy is accelerated recovery. Due to the minimally invasive nature of the procedure, patients typically experience less damage to surrounding tissues. This translates to less postoperative pain and reduced recovery time.

Patients can often begin rehabilitation immediately, facilitating a quicker return to their daily and sports activities. In many cases, patients can start walking with support shortly after surgery, improving their overall mobility.

Lower Morbidity

Arthroscopy generally involves fewer complications than open surgeries. With a lower risk of infections and postoperative complications, this technique tends to have lower morbidity.

The duration of hospital stays is drastically reduced. Many patients are discharged on the same day as the procedure, providing comfort and less disruption to their daily lives.

Accurate Diagnosis and Treatment

Arthroscopy allows doctors to directly visualize the inside of the joint. This provides a more accurate diagnosis of existing problems, such as ligament injuries, meniscus or cartilage damage.

Additionally, the possibility of performing treatments simultaneously, such as repairing a damaged meniscus, improves the overall effectiveness of the procedure. This ability to diagnose and treat in a single intervention constitutes a significant advancement in the treatment of knee injuries.

Risks and Complications

Knee arthroscopy, although a common and generally safe procedure, carries certain risks and complications that patients should be aware of. It is important to know the adverse events that may arise and how they are properly managed.

Common Adverse Events

Adverse events following knee arthroscopy may include:

• Infection: Despite aseptic measures, there is a small risk of infection at the surgical site.
• Bleeding: Bleeding may occur within the joint, which may require drainage.
• Nerve injuries: Some patients may experience damage to the nerves surrounding the knee, resulting in numbness or weakness.
• Venous thrombosis: There is a slight risk of blood clots forming in the leg veins post-surgery.

These problems are relatively uncommon, but patients should be alert to these symptoms and consult a professional if they occur.

Complication Management

The management of complications after arthroscopy depends on the type and severity of the event. For example:

• Infection: Can be treated with antibiotics and, in severe cases, may require additional surgical intervention.
• Bleeding: If present, the doctor may opt to drain the excess blood accumulated in the joint.
• Nerve injuries: These generally improve over time, but physical therapy may be required to aid recovery.
• Venous thrombosis: Early mobilization is recommended, and in some cases, anticoagulants may be used.

Close follow-up and timely medical evaluation are crucial to managing any complications that arise.

Patient Selection Criteria

Proper patient selection for knee arthroscopy is essential to optimize the outcomes of the procedure. There are specific criteria that determine when a patient is suitable for this type of surgery, as well as situations where it should be avoided.

Clinical Indications

Knee arthroscopy is recommended for a variety of conditions. These include:

• Meniscus injuries: Significant tears or damage affecting knee functionality.
• Chondromalacia: Cartilage degeneration causing pain and limited movement.
• Knee instability: Ligament-related problems compromising joint stability.
• Bursitis or synovitis: Inflammation of the structures around the joint.

Patients experiencing persistent pain and functional limitations, and who do not respond to conservative treatments may be considered candidates.

Contraindications

There are situations where arthroscopy is not advised. These include:

• Active infections in the knee joint can complicate the procedure.
• Severe arthritis: Conditions like rheumatoid arthritis where joint changes are very advanced.
• Cardiovascular or coagulation problems that increase the risk during anesthesia.
• Unrealistic expectations: Patients who believe the surgery will resolve problems unrelated to arthritis or mechanical injuries.

Evaluating these factors is essential to ensure a safe and effective intervention.

Postoperative Care and Rehabilitation

After knee arthroscopy, it is crucial to follow an appropriate postoperative and rehabilitation process. This ensures optimal recovery and minimizes the risk of complications.

Immediate Care

Immediate care is vital for recovery. Immediately after surgery, ice should be applied to the knee to control inflammation and pain.

It is recommended to keep the leg elevated for the first 24 to 48 hours. This helps reduce swelling. The doctor's instructions on pain medication administration should also be followed.

It is important to watch for signs of complications, such as unusual swelling or redness. If in doubt, consult the doctor.

Rehabilitation Strategies

Rehabilitation plays a central role in the recovery process. Starting with gentle mobility exercises is essential, usually a few days after surgery. This may include gentle knee bends and isometric exercises.

Over time, the patient can progress to strengthening exercises. Physical therapy sessions, typically lasting 4 to 6 weeks, are highly recommended. The physical therapist will guide the patient in functional recovery.

It is important to follow a regular exercise schedule. This not only improves flexibility but also facilitates a return to normal activities. The key is to progress gradually and avoid overexertion to ensure proper healing.
