Knee arthroscopy
What is knee arthroscopy?
Knee arthroscopy is a minimally invasive surgical procedure that allows orthopedic surgeons to visualize, diagnose, and treat issues within the knee joint using small incisions. Through the use of an arthroscope (a small camera), the surgeon can inspect the knee joint and perform necessary treatments with precision, all while minimizing trauma to the surrounding tissues.
Unlike traditional open surgery, knee arthroscopy offers numerous advantages, including faster recovery, less postoperative pain, and smaller scars. This procedure is highly effective for addressing a wide variety of knee conditions and injuries, making it an ideal solution for both athletic and non-athletic individuals alike.
Why knee arthroscopy? The key benefits
Knee arthroscopy has revolutionized the way knee surgeries are performed. Here’s why you should consider it for your knee problems:
- Minimally invasive with faster recovery: Arthroscopy requires only small incisions, reducing the trauma to the surrounding tissues. This results in a quicker recovery period and less postoperative pain. Most patients are able to return to normal activities within a few weeks, compared to the several months required for traditional surgery.
- Precision in diagnosis & treatment: The camera (arthroscope) provides the surgeon with a detailed view of the inside of the knee, allowing for an accurate diagnosis and treatment. This leads to better-targeted procedures and optimal results.
- Reduced pain & swelling: Since the procedure is less invasive, patients typically experience less pain and swelling compared to open surgery. Additionally, the recovery is much more comfortable, allowing for a faster return to regular activities.
- Smaller scars: Traditional knee surgery often requires a large incision, which can leave visible scars. Knee arthroscopy uses tiny incisions, resulting in minimal scarring that usually fades with time.
- Shorter hospital stay: Unlike traditional surgeries that may require hospitalization for a few days, knee arthroscopy is usually performed on an outpatient basis. Patients are typically discharged the same day as the procedure.
