Part I— “Jill” Questions

1. What is the difference between a tendon and ligament? (1 point)

Ligaments are strong rope like structures that connect the joints and hold organs in place. They hold the bones together and also allow limited movements of the bones across the joint. Ligaments are made up of type I (90%) and III (10%) collagen Tendons attach muscles to bones or to other body parts. Muscles get converted into tendons gradually. They are much thinner as compared to muscles, but transmit the force of contraction very effectively. Tendons are made up of type I collagen.

2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your reasoning and the difference between the two? (1 point) The tibia and fibula of your leg articulates with the tarsals in the foot (anatomically the ankle joint is the joint between the distal end of leg bones, tibia and fibula, and the trochlea of Talus)

3. What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point)

The four major ligaments of the knee are;

1.Patella ligament

2.Anterior and posterior cruciate ligaments

3.Medial and lateral collateral ligaments

4.Oblique and arcuate popliteal ligaments

4. If you were the trainer that initially saw Jill after her fall, describe what her knee probable looked at (Hint-inflammation). Why did the trainers put ice on her knee right away? (1 point) Her knee probably swelled up like a basketball soon after an injury. Ice to reduce the swelling.

5. What did a positive Lachman’s test signify? What are some of the other orthopedic tests the doctor most likely perform on Jill’s knee? (1 point)

positive lachman is essentially diagnostic of complete rupture of the antior cruciate ligament (ACL) - Mechanism: ACL Tear; Anteromedial Rotatory Stability; Anterior Cruciate Ligament ; Anterior...
