The latest advancement in arthroscopic surgery is the Arthroscopy Ultra Wide Angle (UWA). This specialized surgical instrument is designed to improve surgeons' performance during arthroscopic procedures. Using an optical tracking system, the researchers evaluated the movement of the arthroscope during 3 standardized tasks. The findings of the study were analyzed using paired t-tests. A wide-angle UWA is also better suited to patients with small or enlarged joints.
The evolution of arthroscopic instruments began with Eugen Bircher, a physician who pioneered the technique in the 1920s. Originally, it was reserved for the knee or large joints. But in the last half-century, the technique has expanded to other joints, including the ankle and foot. Improvements in lens systems and smaller instruments have enabled arthroscopic procedures to become more widely used. For example, Van Dijk's no. 21 arthroscope features a wide FOV with 150 degrees.
The ultra wide angle of the arthroscope allows the surgeon to visualize the inner structure of the joint with greater accuracy. The scope's lens angle can be adjusted with the help of a specialized cannula. Arthroscopy Ultra Wide Angle is available in two models. Each one has different features and functions, depending on the surgeon's preference and the needs of the patient. The Olympus 4 mm ULTRA is a powerful solution for arthroscopy.
This procedure is performed under general anesthesia. The distractor is loosened one notch to facilitate visualization of the lateral and medial gutters. A noninvasive distraction method, using a toe trap attached to a rope and pulley system, is also used. This semi-controlled distraction is a good option for patients who need to undergo a procedure on their foot or ankle. This type of procedure is more effective than the conventional method and is less invasive than other forms of arthroscopic surgery.
The results of this procedure are the most predictable when performed by an experienced surgical team. The surgeon can operate on a large area without causing significant damage to the surrounding tissues or injuring the origin of the deltoid muscle. The procedure typically takes a few hours under general anaesthesia and has little to no discomfort. A video is usually taken during the procedure. While the patient may feel some discomfort, the procedure itself is typically painless.
In addition to identifying fractured joints and other abnormalities, this procedure can help doctors repair ligaments that hold the joint together. The risks are minimal, and the outlook is generally good. Recovery time and prognosis vary. During this minimally invasive procedure, a supine position is required. However, this procedure is also safe, and many patients have no side effects at all. It is also used to treat fractures of the patella.
