Orthoscopy used in optics and vision for the condition of normal, distortion-free view, from "ortho", straight, right, correct, and "scope", seeing.. Abbe in 1880 [1] designed an orthoscopic eyepiece for stereoscopic microscopes which minimized distortion.
Arthroscopy (also called arthroscopic or keyhole surgery) is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision.
As with many words derived with the "æ" ligature, simplification to either "ae" or just "e" is common, especially in North America.In the US, the majority of college, university, and residency programmes, and even the American Academy of Orthopaedic Surgeons, still use the spelling with the digraph ae, though hospitals usually use the shortened form.
Orthoscopic eyepiece diagram. The 4-element orthoscopic eyepiece consists of a plano-convex singlet eye lens and a cemented convex-convex triplet field lens achromatic field lens. This gives the eyepiece a nearly perfect image quality and good eye relief, but a narrow apparent field of view — about 40°–45°.
Systems free of distortion are called orthoscopic (orthos, right, skopein to look) or rectilinear (straight lines). Figure 4. This aberration is quite distinct from that of the sharpness of reproduction; in unsharp, reproduction, the question of distortion arises if only parts of the object can be recognized in the figure.
Hip arthroscopy refers to the viewing of the interior of the acetabulofemoral (hip) joint through an arthroscope and the treatment of hip pathology through a minimally invasive approach.
Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny fractures in the underlying bone.This causes new cartilage to develop from a so-called super-clot.
Manipulation under anesthesia (MUA) or fibrosis release procedures [1] is a noninvasive procedure to treat chronic pain which has been unmanageable by other methods. MUA is designed not only to relieve pain, but also to break up excessive scar tissue.
