Summary
The 70° arthroscope offers superior visualization for many common arthroscopic procedures, including shoulder stabilization and knee ligament reconstruction, compared to the standard 30° arthroscope.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Standard arthroscopic visualization relies heavily on the 30° arthroscope.
- The 70° arthroscope, despite its described applications, is underutilized in contemporary practice.
Purpose of the Study:
- To re-evaluate the utility of the 70° arthroscope in various arthroscopic procedures.
- To identify specific circumstances where the 70° arthroscope provides enhanced visualization over the 30° arthroscope.
Main Methods:
- Systematic exploration of the 70° arthroscope's application across a range of common arthroscopic surgeries.
- Comparative assessment of visualization quality between 70° and 30° arthroscopes.
Main Results:
- The 70° arthroscope demonstrated superior visualization in several procedures.
- Specific applications include shoulder stabilization, distal clavicle resection, AC joint reconstruction, rotator cuff repair, elbow arthroscopy, ACL and PCL reconstruction, posterior knee arthroscopy, hip arthroscopy, and subdeltoid shoulder arthroscopy.
Conclusions:
- The 70° arthroscope is a valuable tool that can significantly improve visualization in numerous arthroscopic procedures.
- Revisiting and incorporating the 70° arthroscope into surgical practice can enhance surgical outcomes.

Endoscopic Procedures III: Video Capsule Endoscopy
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
