Meniscus

For this lab there were two debriefs, in these debriefs we, as a class, discussed the topic of surface tension, meniscus, and how they affected our experiment. The meniscus, also stated before, gave the students a measuring problem in the beginning, when filling up the graduated cylinder to 100 mL. In Lab Debrief Part One, we discussed this situation and later found out that the meniscus was a curve of the liquid and could be either convex or concave. An observation in the experiment was when the pennies were displacing both water and milk, which created convex meniscus; this was the effect of surface tension. Surface tension was a large aspect of our experiment because this was what made more pennies fit into the water rather than the milk. Surface tension is defined as the cohesive force between particles which ties them together, and creates an elastic bubble on top of the graduated cylinder. In the end, the water had a stronger amount surface tension, therefore, it was able to hold five to ten more pennies then the…

Torn Meniscus Stop! That is what happens to an athlete who has torn his or her meniscus. This represents one of the most common knee injuries (Mayo Clinic Staff). It affects 61 in 100,000 people per year (“Meniscal Injuries”). A torn meniscus often happens to athletes, it is a knee injury that can be treated and fully recovered in just a couple of months with the correct medical attention. What is a meniscus tear? What may be the causes of a torn meniscus? How does one know if they have…

Life holds a series of setbacks; every day we deal with problems that affect us on a personal level. In my four years of college, I have definitely had my fair share of setbacks through athletics and my living arrangements at Saint Peter’s University. My freshman year, I came from a slow, quiet suburban childhood into the fast and nonstop environment of Jersey City. The following year, I tried to take on more responsibility by renting a house near campus with my teammates, but I ended up stuck…

POP! Your ACL just snaps in half. The pain is unbearable. It feels like your knee is just hanging because nothing is holding the back part of your knee together. You are scared to get the MRI results back because it is a huge setback. “You’ve torn your ACL.” Those are words an athlete never wants to hear. What is Your ACL? You may be wondering what your ACL is and what it does? Your ACL is the Anterior Cruciate Ligament. It is one of the four ligaments that stabilizes your knee so there is no…

, & Jomha, N. M., 2015). What even is a meniscus? Menisci are crescent-shaped portions of fibrocartilage located in the knees and can actually be found in other joints, but injury primarily takes place in the knees. These injuries are also closely associated with ligament sprains (Lewis, S. M., 2011). Alone, this type of damage does not usually cause significant edema or swelling due to the fact that most of…

the interfaces of materials of different magnetic susceptibility, such as bone-soft tissue or air-tissue interfaces. ( 45 ) 6- Partial volume Partial volume artefacts arise from the size of the voxel over which the signal is averaged. Objects smaller than the voxel dimensions lose their identity, and loss of detail and spatial resolution occurs. ( 46 ) NORMAL ANATOMICAL VARIATIONS: MENISCI Morphological variants of the shapes of the menisci were macroscopically noted and…

ABSTRACT Purpose: This study was undertaken to diagnose and to document clinical results and the technical aspects of arthroscopic meniscus repair for treating the recurrent subluxation with peripheral tears around popliteal hiatus of the LM. Methods: Twenty three patients (24 knees) with symptomatic recurrent subluxation of the LM treated by arthroscopic meniscus repair were included. The inclusion criteria were (1) patients with knee pain, locking or snapping symptoms despite 3 months of…

The inner meniscus is avascular which means that it has less healing potential [9]. Buma et.al also state that meniscus which constitutes a fibro-cartilage tissue has a limited regenerative capacity [12]. The ongoing challenge for clinicians and researchers is to improve the healing process in this type of injury. Some of the new approaches include the use of parameniscal synovial tissue, trephination of the peripheral meniscus rim with suture of the meniscus tear, creation of vascular access…

tears are the most common orthopedic procedure performed. Out of the procedures, two-third is traumatic, while the remaining one-third is idiopathic. The medial is semicircular and lateral is a complete circle. The meniscus is made out of fibrocartilage, type I. Blood supply depends on the capillary as one-third of the ring is avascular, also known as the part that can heal. The function of the meniscus is to load absorption and serve as a shock absorber when pressure is applied across the knee.…

of the peripheral body of the lateral meniscus, indeterminant in age. Compression and erosion of the body of the medial meniscus is seen with a complex of small tears in the posterior horn, indeterminant of age. There is a cluster of small subchondral cysts in the proximal mid tibia with surrounding edema of indefinite age. Small knee…
