Q

Two main types of cartilage in the knee? Describe them?

A
  1. Articular cartilage: a thin lining of resilient connective tissue that serves as padding and an ultra low friction surface
  2. Meniscal cartilage: serve to deepen the contact of the femur on the tibia, provide stability, distribute force

30
Q

Lateral and Medial Epicondylitis

Treatment consists of ?
5

  3. Compression
  4. Elevation
  5. Anti-inflammatories
31
Q

Lateral and Medial Epicondylitis

For recalcitrant cases? 2

A

32
Q
  1. What is Platelet Rich Plasma?
  2. Extracted from?
  3. Delivered and works how?
A
  1. High concentration of functionally viable platelets and their associated growth factors
  2. Extracted from a small amount of patients blood: 9-18cc
  3. Delivered arthroscopically/open and placed directly into the tear site to stimulate a reparative healing response for soft tissue and bone repair
33
